Spotted Hyenas, Kenya - East Africa

2012-02-04T03:45:08Z

Continuing with the African theme. Despite vehicle issues and occasional appalling weather conditions, wildlife was plentiful.

Whilst tracking cheetahs, I had observed a number of spotted hyenas and was keen to photograph some of the hyena behaviour at a den. Finding a den isn’t that difficult if you have an off-road access permit; we were driving long distances daily and we already knew the location of three hyena dens.

Order Carnivora / Family Hyaenidae - Hyenas

The family Hyaenidae consists of three species; each living within a broad habitat range within Continental Africa. The smaller and shy brown hyena (Hyaena brunnea) occurs only in southern Africa and the Spotted Hyena (Crocuta crocuta) and the rarer Striped Hyena (Hyaena hyaena) inhabit East Africa.

Although the spotted hyena is not endangered – its numbers are actually increasing due to the decline in African wild dogs numbers, research is still conducted my scientists interested in hyena behaviour and population distribution. Although not commonplace, you see the odd hyena sporting a fashion accessory in the name of research: a tracking collar that emits either a GPS location or a radio transmission beep so researchers can track the individual.

Social Behaviour

The spotted hyena is the most social of the Hyaenidae in that it has the largest group sizes and most complex social behaviours. Its social organisation is unlike that of any other Carnivore, bearing closer resemblance to that of primates (baboons and macaques) with respect to group-size, hierarchical structure, and frequency of social interaction among both kin and unrelated group-mates. However, the social system of the spotted hyena is openly competitive rather than cooperative, with access to kills, mating opportunities and the time of dispersal for males depending on the ability to dominate other clan-members. Females provide only for their own cubs rather than assist each other, and males display no paternal care. Spotted hyena society is matriarchal; females are larger than males, and dominate them.

A Highly Successful Animal

The spotted hyena is a highly successful animal, being the most common large carnivore in Africa. Its success is due in part to its adaptability, cunning and opportunism; it is both an efficient hunter and a scavenger, with the capacity to eat and digest skin, bone and other animal waste.

LEFT: A spotted hyena carries the mane and mandible of a recently brought down and killed wildebeest.

In functional terms, the spotted hyena makes the most efficient use of animal matter of all African carnivores. The spotted hyena displays greater plasticity in its hunting and foraging behaviour than other African carnivores; it hunts alone, in small parties of 2-5 individuals or in large groups. During a hunt, spotted hyenas often run through ungulate herds in order to select an individual to attack. Once selected, their prey is chased over long distance, often several kilometers, at speeds of up to 60 km/h.

I witnessed several occasions when a pack of hyenas attempted to separate a young wildebeest from its mother, and I have a fond memory of a pack of ten hyenas trotting over a rise on a hill at dawn after a night’s long-range hunting patrol.

I my next post, we will look at the mating rituals of the spotted hyena and have a closer look at hyena pups within the den.

Blog Updates Have Been Minimal

2012-02-04T03:44:37Z

Blog entries have been few lately; I’ve been working closely with an overseas conservation agency supplying a number of photographs & short video clips. I’ve also been busy arranging schedules for a number of photographic trips this year. Organising a trip is always a time consuming activity and often keeping a blog up-to-date takes second place to trip logistics and working with organisations to produce and supply images.

Toyota Landcruisers are Tough - Kenya, East Africa

2011-12-15T00:47:27Z

If I hear this comment one more time I’ll scream….

Five weeks in Africa self drive can be very damaging to a motor vehicle, more so if you have an off road permit. In Australia I own a Toyota Landcruiser which is an excellent vehicle and takes me to some out of the way places, but my vehicle is regularly maintained. The rental vehicle in Africa was Toyota Landcruiser troop carrier. In many respects a similar vehicle with the exception that this four wheel drive hadn’t been regularly maintained.

Australian Landcruisers Are Tough

The lineage of this vehicle was Australian and it had been purchased second hand from Telecom, the Australian communications company. On the outside the 4X4 looked OK, and for the first week or so performed admirably. But as time passed, problems began to present themselves.

LEFT: Field repairing the front left spring which began to break due to rough road conditions. Masai Mara warriors watch as we work!

Apart from the usual flat tyres and getting stuck a few times in deep mud, we had more insidious issues. The front springs were makeshift and had been replaced incorrectly; we were afraid that with the workload they would fall apart leaving us stranded in “lion country”. Further, the roof hinges for the observation roof were damaged and rattling like chattering teeth and the attachment points of the bulbar to the chassis were loose due to poor welding. Shock absorbers were – well let’s say they didn’t absorb anything at all! But we continued using the vehicle until the inevitable occurred.

LEFT: We wondered if "this" would be our Toyota in a year or so!

Mechanical Problems

BANG – while driving along the dirt track, the hinges of the roof hatch broke and the heavy metal hatch flew forward onto the bonnet (hood) of the Landcruiser. It then hit the bull-bar which reflected the hatch back towards the windscreen – SMASH. In 30 seconds the windshield was cracked and the hatch was lying loose. Repairs were necessary so we drove to the nearest town and mechanical repair facility. The name “repair facility” is erroneous, as these guys were not mechanics but locals who knew a little bit about mechanics – just enough to be dangerous. They repaired the car for a few dollars and away we went satisfied that all was OK.

LEFT: Field welding the bullbar back to the vehicle chassis.i

A few days later, BANG!! We hit a hole in the ground and the vehicle lurched precariously to the side. Inspecting the damage it was noted the bulbar now had fallen off the car, the rear tyre carrier had also broken away and the shock absorber – well what shock absorber! It was gone. Another visit to our newly made mechanical friends soon rectified the situation – for a few dollars. The locals shrugged off our comment about regular maintenance, log books and the like – “Hey this Africa” they chanted.

As we departed the repair facility, we could only wonder if this was going to be a regular affair. A few days later as we crossed a rather deep and rocky river crossing – BANG!! The vehicle sunk to the chassis in the centre of the river. Our first thought was crocodiles, but there were none nearby. We literally smashed the transmission repeatedly into forward and reverse as we attempted to extract ourselves from the hole. BANG!! Was that the drive shaft or the front diff hitting a submerged rock– who knows! Climbing from the river we inspected the vehicle again. The front springs were not looking healthy! Further, the steering was suspect as the car veered sideways when driving. Time to say hello to our local friends again and here the ominous words “Hey this is Africa” as we parted with a few more dollars….

This visit identified additional mechanical issues. As we drove into the town locals jumped about and wildly pointed at the front wheels. Alighting from our chariot to inspect the front wheels we were “delighted” to see that the right hand tyre was sitting at a crazy angle!! The upper bearing had broken and wheel was about to vacate the car!

Authorized Toyota Repair Facility – Ahhh No

It soon became apparent that this was NOT an authorized Toyota repair facility as we watched the bearings being replaced. The bearings were striped apart and placed on the sand – YES read sand. They were then cleaned with petrol by a young African smoking a cigarette (I stood well away). New grease was not applied to the bearings but rather they used the older sand-entrained grease. When I mentioned this to the head mechanic, he quickly smeared some new grease over the older grease looking at me with a smile that said “Hey this is Africa”….. A few dollars and once again we were on our way!

The final straw was a few days later when we hit a rather large hole whiles travelling off-road. BANG!! Inspecting the car we noted more issues which included the front springs looking slightly “more” bent than what they were a week earlier. We drove on but stopped when we noticed we no longer could hear a rattle that had been present for two weeks. To our horror we found out why there was no rattle; the sidebar, which was the cause of the rattle, had vanished! It must have fallen off on one of the river crossings! We looked or the sidebar but never found it.

The vehicle served us for three weeks. It was then decided, in lei of the amount of time being spent having the vehicle repaired, that it was prudent to rent another vehicle form Nairobi with a driver. After this decision, our repairs ceased and although the local mechanics waved to us every time we passed through town, we never did stop to hear the words “Hey this is Africa” again.

LEFT: Field repairs were a constant ordeal and we were always keeping an ear to the ground listening for something else falling off, or breaking on the vehicle. Tyre repairs and changes were common and in "lion country" need to be done as quickly as possible, Here a Masai Mara warrior lends a hand to Uwe as a damaged tyre is replaced.

Other Issues

Of course if the above mechanical issues were not enough to keep us on our toes, there were also battery problems. The battery was new but the wires and alternator were old - very old! I have SOG to thank for making a very robust knife tool (like a leatherman). I used this on several occasions to repair the alternator and arc the battery terminals so the car would start! I can remember at one stage we all were pushing the vehicle in an attempt to clutch start it, but it got away from us and started chugging along the track without its passengers; We were madly running after the car!! An except from the movie flick "The Gods must be Crazy" crept into my mind as I clamored aboard.

But, as they say "this is Africa"...

Photographing Intimate Moments

2011-11-30T04:29:12Z

Photographs are “just photographs” unless they capture something special regarding the subject.

Left: A black-browed albatross (Diomedea melanophris) tends it's sole chick in the Falkland Islands.

In today’s digital world, there are so many images of animals that it’s easy to view images as a just another animal “snap”. To elevate your image to the next level you need to do something more than just being at the location for a fleeting moment and squeezing the shutter button. Certainly, a well lighted, technically correct and suitably composed photograph is several steps in the right direction, as is a rarely photographed animal. But, what can be done to separate your image from the rest of the crop.

I’ve discussed photographing defining moments in an earlier blog post, but what about intimate moments.

Intimacy

Capturing an intimate moment with wildlife is often serendipitous; however, knowing the behaviour of your target species is advantageous as it allows you (the photographer) to have a “somewhat slightly fractured” crystal ball to predict the behaviour that will occur. Although animals do alter their behaviour to changing environmental situations, they do not change their base behaviour. Spending as much time as possible with an animal will greatly increase your chance to observe differing behaviour and photograph, either a defining or intimate moment.

In this photograph of a Black-browed Albatross, the intimate behaviour is the subtle expression on the adult and chick’s face as they face each other in the nest. I waited for two hours on a cliff ledge in the Falkland Islands to be given the opportunity, to capture this connection between the chick and its parent. I have many “snaps” of albatross in similar positions with similar lighting, but the expression of intimacy portrayed in this image, is what separates it from the others.

Is the Intimate Connection Real?

Was there an actual connection between the chick and the parent? This is a difficult question to answer; it depends upon whether you believe animals’ have the ability to “feel” as humans do.

I rarely have anthropomorphic responses towards an animal’s behaviour, however, many individuals who view my images do. Therefore, photographing intimacy between animals is well worth the effort because it separates your photograph from the many hundreds of “snaps” already out there in the marketplace.

Anthropomorphism is any attribution of human characteristics (or characteristics assumed to belong only to humans) to animals.

The Hunt, Chase & Kill - Wild Cheetahs in Kenya, East Africa

2011-11-06T07:56:09Z

The Hunt

The following morning, whilst travelling the usual rough route from the camp to the last known position of the cheetahs, our luck appeared to change. The brothers were on the move and tailing a large herd of wildebeest. Quickly driving to a suitable shooting position in relation to the sun, we prepared our cameras for what was hoped would be a kill.

LEFT: A cheetah moves out from the cover of the stream and makes his way toward the herd.

One of cheetahs climbed a termite mound, to see further ahead, before setting off at a fast trot moving toward our vehicle. In an instant, the feline was transformed from a sleeping house cat to a highly mobile killing machine. It was so fast, almost a blur, as the cat shortened its distance between itself and the herd of wildebeest. The target was a largish individual, enough to sustain the three hunters. But where were the other hunters – only one was chasing the target prey. The other two hunters were lolling behind enjoying the morning sun while playing in the grass!

LEFT: A male cheetah, bypasses a fleeing wildebeest as it locks onto an individual within the herd.

Confrontation

The wildebeest, perhaps sensing an untrained solo hunter, stopped running and turned while lowered its head to confront the cheetah. A brief exchange took place whereby the wildebeest charged the cheetah attempting to injure the adolescent with its two flailing front legs and hoofs. The cheetah made a fleeting attempt at grabbing the rear flank without success before retreating to a safer distance from the aggressive wildebeest.

LEFT: Adult wildebeest are no easy match for a cheetah. The wildebeest rather than run, stops and confronts the cat.

The hunt had ended and the cheetah was left standing, panting and looking towards his brethren with a disdainful look on his face which clearly said “where were you?” The hunt, run and attack was a failure due to poor cooperation between the trio.

Let’s Try Again…

A lager (a thin strip of thick vegetation that hides a watercourse) was directly in front of the moving wildebeest. We decided that the prime shooting position would be with the sun behind us on the quarter at the other side of the lager. To reach this position required us to drive across the rough lager and a small stream.

LEFT: Paws outstretched, a cheetah brings down a wildebeest after a short but very fast run.

Meanwhile, the trio had reunited and were making a steady pace behind the herd. We were certain a kill would happen this morning; the cheetahs were active and we knew they must be hungry!

The wildebeest slowly moved around our vehicle; for a moment I was concerned our presence would predetermine the direction of the herd. However, this didn’t occur as the animals abruptly altered direction moving away and to the left of our vehicle. The herd comprised a number of mothers with first born, inexperienced adolescents, and old salts. It’s the young and inexperienced that are usually targeted by predators.

LEFT: The prey is now dead and the cheetahs share the choice pieces of the kill. One cheetah drinks fresh blood from a severed artery whilst another chews on a flank.

The cheetahs, following each other, pushed through the dense vegetation of the lager and stopped short of the savannah. The cats assessing the situation quickly, realized that the herd was moving towards them. They broke from the cover provided by the lager and began to walk toward the herd maintaining what cover was available from the natural contours of the land. The herd hadn’t noticed the three slick cats, until they bounded from a walk to a very fast run, which became a blur as they shortened the distance to the herd. The wildebeest finally saw the danger and the lead animals broke into a run which translated to a wild frenzy of movement as each individual in the herd panicked. The hunting had ended and the chase had begun.

The Hunting Had Ended & The Chase Had Begun

It was too little too late! The three cats were amongst the herd and it was difficult to think that the hunt would not be a success. At first, each cat appeared to target what he thought was a prime individual, but as they ran along the side the herd, a dedicated target was selected from the many. The three cats, in marvellous co operation ran the ‘chosen one” away from the protection of the central section of the herd. The singled out wildebeest ran fast, weaving and dancing in an attempt to remove the ‘target lock” achieved by the cheetahs. The individual selected was not an inexperienced youngster, but a fully grown adult who was more than capable of outfighting a single cheetah, but what about three cheetahs acting as one unified force?

Feline Cooperation

The first cheetah pawed the rear leg of the wildebeest, but missed!; the resultant inertia forcing him to loose his footing and fall to the ground. The second cat manoeuvred himself to the front of the wildebeest causing the stricken animal to alter direction and loose speed. The third cheetah made his move and with two paws outstretched, fastened himself to the rump of the now highly panicked animal and wrestled him to the ground. Attempting to get a better purchase on the animal, the cheetah released his grip and the wildebeest, realizing his opportunity, jumped from the cheetah’s grasp to make an escape. However, by this time the first cat, recovered from his fall, leapt onto the rear of the animal, bringing him down before he could make good his escape. The cheetah that had lost his initial purchase on the rump, quickly climbed onto the panting wildebeest holding him to the ground. It was over. The death of one would be the life of three.

The hunt, chase and kill had transpired very quickly. Now there was a stricken wildebeest lying on the ground with two cheetahs beginning to feed, whilst the third kept a careful watch for intruders.

LEFT: Two hungry cheetahs begin to feast on the still live wildebeest whilst a third cheetah watches for other predators. It's unusual behaviour for cheetahs to feed on still-living prey.

While one of the brothers tore the flesh from the favoured area of the animal; the rear haunches, his brethren began to open an area in the region of the neck, to drink the fresh blood. Blood is very rich in iron and often is drunk by animals as a vitamin supplement to water. The luckless victim continued to try and make an escape, but clearly this movement was instinctive. I was told by the KWS ranger that cheetahs rarely eat live food, and to do so, probably can be explained by heightened hunger.

In between feeding, each cheetah in unison would stop momentarily, raise himself high from the ground and scan the horizon for danger. A lion or hyena group could easily steal the carcass and perhaps injure one of the trio. Overhead, vultures attracted to the recent kill, began to circle the carcass.

Unusual Cheetah Behaviour

The normal practice for cheetahs is to “rush their meal” for fear of losing it to another scavenging animal – the behaviour is almost “hit and run”; but, thirty minutes had gone by and the three brothers were still eating! This was not normal behaviour.

The flanks had been consumed and now the trio were demolishing and feeding upon the remainder of the carcass. A lone jackal, attracted by the smell of blood boldly made his way towards the carcass, however, the brothers had little intension of sharing their food with a non family member and quickly charged the jackal, putting this “lower predator” into its rightful place. Eventually the jackal was successful in steeling a morsel (the stomach).

LEFT: A male cheetah lifts its head from early dining to sneer at a Jackrel that wants her share of the free food which the jackrel did not earn....

The three brothers, whose bellies were now visibly distended, had within forty minutes consumed most of the accessible meat from the carcass. Immediately after the last cheetah had left the remains, the waiting vultures descended and began to rip apart the remainder of the flesh. The transition was swift; it reminded me of a hoard of flies attracted to a piece of left over meat at a summer BBQ, or perhaps a school of piranha attacking a hapless victim in Amazonian waters. Literally within minutes, the bones were picked relatively clean with only the rib cage showing above the grass. Nothing went to waste.

Cheetah Cubs

I'll return to the cheetahs at some stage in the future, however, I won't be discussing the three brothers. Instead, we'll have a glimpse into the life of three, very playful one-week old cheetah cubs and their mother.

The Three Brothers, Cheetah (Acinonyx jubatus) - Republic of Kenya

2011-10-17T03:02:53Z

The small thermometer I had on my photo backpack said it was 45 degrees Celsius; I thought about repositioning the device, but then realized that it was already in the shade.

I was sitting in the rear of a Toyota Landcruiser crammed in amongst various pieces of photographic equipment, and a very large cooler which carried breakfast and lunch. I’d been sitting here for 3 hours watching three young cheetahs, and the temperature didn’t seem to be decreasing. The cheetahs had the right idea – sleep, and I’m sure I dozed off now and again, only to be woken by several dozen squadrons of annoying flies buzzing around my head.

LEFT: A male cheetah (Acinonyx jubatus) watchful for prey or predators.

The Three Brothers

The three male cheetahs, nicknamed “The Three Brothers” by the Kenyan Wildlife Service (KWS), are a tad over a year old and belong to the same litter.

“Cheetahs are usually solitary or are seen in pairs. A trio co-habitating is quite uncommon” stated one of the KWS rangers I had spoken with earlier that day.

Our task this day, and for the following several days was relatively simple; follow the cheetahs to observe their behaviour and hopefully photograph the animals hunting and making a kill.

Cheetahs are one of the most beautiful cats to be found in Africa, and in my opinion rate second to the leopard. Evolution and natural selection has developed an animal that is exceptionally adapted to chasing and killing certain types of prey. The cheetah is the fastest of the big cats and is superbly adapted for speed, able to retain speeds of 112 km/hr (69 mph). This speed equates to roughly 32 meters per second (32 m/s) and can be maintained over an average prey chase of 2.7 kilometres (3.5 miles).

But, as with most predators when not hunting, they sleep to conserve energy - and this is exactly what the three brothers were doing, only occasionally stirring to check on the location of a number of Thompson gazelles that were browsing nearby.

Cheetahs Are Skittish Animals

Cheetahs, in comparison to other apex predators such as lions and leopards, are skittish animals forever watchful and alert. They are the “scaredy cats” of the feline family. A cheetah won’t take unnecessary risks, and often will retreat upon conflict with another animal – especially a lion which are known to kill cheetahs. A mother with cubs is especially vulnerable and often cubs will be killed by hyenas and lions. At these times the mother will move away from areas heavily populated with prey to minimise any interaction with other predators.

The Three Brothers inhabited a lightly vegetated area adjacent to surrounding plains; this is the favoured habitat of cheetahs as it provides vegetation to hide behind, and open ground from which to exercise their one benefit over other predators – speed. Unlike lions, which mainly hunt at night, cheetahs prefer to hunt during the daylight hours, thereby minimising the chance of injury such as falling into a hole while running at high speeds.

Fussy Eaters

Searching for the cheetahs each day revealed that over the past week or so they had hunted and made several kills; the remains of their kill was evident as we searched the open ground and beneath shady bushes. Cheetahs, like some house cats, are fussy eaters; they prefer smaller animals such as gazelles, and then only consume the choicest cuts – normally the rear flanks, leaving the remainder of the kill for hyenas, jackals or vultures.

LEFT: On the brothers wakens briefly and yawns whilst his brethren sleeps adjacent.

Several times, we observed prey animals and positioned the four wheel drive in a suitable place to film any resultant hunt and kill; however, it became evident that as the brothers were three, a gazelle hind quarter was not going to be enough food to sustain them. I’d read that cheetahs hunt three to four times a week; daily when bringing up cubs.

We knew the brothers were hungry….We knew they had to hunt soon…We had an inkling that they wanted something more sustainable than a gazelle, but when would they make their move?

In my next post, I’ll describe the hunting technique of the three brothers and we’ll learn whether they were successful or not.

Black-browed Albatross (Thalassarche melanophrys) - Falkland Islands

2011-09-20T12:18:00Z

One would be remiss when discussing the Falkland Islands not to include the albatross. The islands are the breeding ground for 70% of the world’s population of Black-browed Albatross (Thalassarche melanophrys). Several colonies dot the archipelago with the largest colony located on Steeple Jason Island, an isolated island in West Falklands.

LEFT: Male and female black-browed albatross court to reunite the monogamous lifetime bond that unites the pair.

This species normally nests on steep slopes covered with tussock grass and sometimes on cliffs. They are an annual breeder laying one egg from between September and early November. Incubation is done by both sexes and lasts roughly 70 days. After hatching, the chicks take 120 to 130 days to fledge. Juveniles will return to the colony after 2 to 3 years but only to practice courtship rituals, as they will start breeding around the 10^th year.

This delayed time until sexual maturity is one of the reasons that these birds, also called Mollyhawks because of their distinguishing black brow along the eye, is listed on the IUCN Red List as endangered. The population of albatross in the Falklands has declined 67% since population counts began in 1964. This decline is attributed to the increase in long line fishing practiced along the Patagonian Shelf and in particular off the coast of South Africa which is one of the regions the birds migrate to when feeding.

During my three weeks in the islands I was fortunate to visit 2 breeding locations and spent several days at one of the colonies. Sitting quietly along the cliff edge for many hours a day, the birds became very accustomed to your presence and for the most part lost their fear of humans and became increasingly curious. I had one fellow leave his nest and adolescent chick and waddle toward me to peck at my boot laces, hand and camera lens. It’s experiences such as this that make the often laborious task of wildlife photography worthwhile. If more people could appreciate the connection that occurs between species during such occurrences, then perhaps more people would be concerned about protecting habitat and allowing space for wild animals to remain wild.

In the late afternoon when the breeze freshens is when the albatross truly show their grace. Taxi and liftoff is somewhat ungainly and is final approach and landing, however, in flight their nothing that matches the flight dynamics of the albatross. Their massive wingspan allows great lift and its possible for albatross to fly distances of thousands of kilometers with barely a wing beat. Often albatross can be seen skimming over waves and swells flying an almost nape of the earth pattern. They achieve this ability by harnessing the air pressure that the passing waves produce.

LEFT: Black-browed albatross looks carefully at its own reflection in the camera lens.

I recall one afternoon when weather conditions were inclement for the best pilots to remain grounded; visibility was reduced to less than 100 meters and winds were buffeting to 40 knots. The albatrosses were cleared for takeoff and several dozen individuals were flying patterns along the cliff edge. Sitting on the cliff top was hazardous not for the risk of falling, but by being struck by one of birds diving overhead and making low passes to investigate me. Often all that was heard was a whoosh as an albatross cleared by head by inches! This said, the bird is a master in the air and if I kept still there was minimal chance that I would be hit unless a bird was in landing approach, which is very ungainly and would cause concern to the most experienced pilot.

Tasmanian Devil Babies - Tasmania

2011-08-19T12:45:01Z

During June and July the female Tasmanian Devils (Sarcophilus harrisii ) aren't very active and finding them can be difficult. The reason for their slumber is that most are heavily pregnant or have given birth to young. Amazingly up to 50 young can be born and the joeys must race a distance of about 3 inches (7.6 centimeters) from the birth canal to the mother’s rear-facing pouch, where they compete to attach themselves to one of only four available teats. Only those four will then have a chance to grow and survive.

LEFT: A female Tasmania Devil ((Sarcophilus harrisii) rests on her back revealing three large joeys.

August is the time when the devils are beginning to develop fur and their eyes are opening; for the most part the joeys are still attached to the teats. At this stage of development, the youngsters are growing rapidly and depending upon the number of young in the pouch, it maybe difficult for the mother devil to accommodate them all. The mother devil will scavenge and hunt prey during this time while carrying the babies in the rear-facing pouch attached to her nipples.

LEFT: A large heathy male devil baby, guard hairs reflecting in the sun, suckles.

During this time, mother devils attempt to keep beneath the radar as much as possible, as protecting their infants is their prime responsibility and concern. Other devils (male and female) but particularly male devils may try and kill the youngsters The reasons for this are varied but include :protecting food resources (less food to share), reducing rival male devil's DNA by killing the rival's young, and causing the female to become receptive again.

When the young finally are too large, they emerge from the pouch and often ride on their mother’s back, like young koalas or possums, or are dragged along underneath her, still attached to her nipples. After about six months, the young are weaned, leaving the mother to live alone in the bush by late December until the following march when courtship and mating begins again.

Rockhopper Penguins (Eudyptes chrysocome), Falkland Islands

2011-08-03T08:07:20Z

Rockhopper Penguins (Eudyptes chrysocome chrysocome) are the smallest of the crested penguins with a circumpolar distribution. They are also one of the most common penguin species in the Falklands. The penguins which weigh between 2 and 2.7 kg get their name because they move around by hopping keeping both feet together. Despite, what may seem as hindrance, they are exceptionally agile on land; I was constantly amazed by their ability to tackle the most challenging terrain as they ledge-hopped on precipitous cliff faces!

If you inspect the cliffs closely you can see the narrow cuts and crevices created by the sharp toe claws on the penguin s feet. The carved sandstone provided evidence to the millions of penguins that have moved across the rock over thousands of years.

LEFT: After an arduous cllimb of 50 meters, a rockhopper penguin bellows its success in the late afternoon light.

Every evening the rockhoppers porpoise towards the steep sea cliffs riding the large South Atlantic swells. More than once the penguins, who gather into a raft for safety just out from the breakers, are pulverised onto the sharp rocks. I watched a small group land successfully onto a flat rock and begin to hop to safety only to be swept away again by another large wave. If this is not enough, predators cruise the coast near the breeding colonies seeking an easy kill. Southern elephant seals, leapoard seals and killer whales regularly lie in ambush waiting for the penguins to begin their waterborne assault.

Rockhoppers live in large colonies often mixed with albatross or imperial shags. They are noisy and quarrelsome little creatures but their comical antics and inquisitive personalities make them very endearing and they soon become the favourite penguin for many visitors.

Currently they listed as vulnerable by several conservation agencies with an overall decline in most populations. The speculated reason for this decline is the rise in sea surface temperature (due to global warming) which has affected the prey stocks of rockhopper penguins.

Breeding
Rockhopper penguins are very synchronised in their breeding cycle both within a colony and across years. Males return to the island in mid-October and females a few days later. Nests are re-established (with most returning to the same nest sites and mates) and two eggs laid, with the smaller first egg never producing a chick to fledging.

LEFT: The afternoon rush hour as food-ladden rockhopper penguins make their way to the colony to rejoin their mate and offspring

Females take the first incubation shift while males, who have not eaten for some 4 weeks, go to sea to forage. On the males return, the females depart for a foraging trip and return as the chicks hatch. Females provide all food for the chick when it is young and when absent from the nest (food foraging) the male will undertake guard duty. But once chicks enter a creche, both parents forage.
Chicks fledge at the end of February. At this time adults go to sea to fatten for the moult, which they undertake in early March. After finishing the moult they depart the breeding areas in late April.

Diet and Feeding

Rockhopper penguins eat predominantly euphausiids, myctophid fish and squid which they hunt for in the Polar Frontal, Zone.
