Chobe’s winter birdlife

This post shows a selection of the images of birds seen along the Chobe river in June 2021, mid-winter in southern Africa. Almost all the images were taken while on a CNP Safari from CNP’s specialised photographic boat. The perspective from the boat is ideal and the wildlife allows you to get much closer on the water than on land. Winter is obviously a time when all the migrants have flown north for warmer climes where there is more food, especially insects.

“I think the most important quality in a birdwatcher is a willingness to stand quietly and see what comes. Our everyday lives obscure a truth about existence – that at the heart of everything there lies a stillness and a light.” ~ Lynn Thomson

As a change in format for this post I have decided to show more images with a brief description of the birds. For anyone interested in birds and bird photograph, the Chobe offers wonderful photographic opportunities and should be on the to-do list for all serious bird photographers

A female Comb duck in flight. The angle of the sun dictates whether we see the beautiful iridescence on the wings of not. In this image their was just a hint of the iridescence on the wings.

A pair of White-crowned lapwings noisily declaring their territory.

A female Blacksmith lapwing sitting on her eggs in the morning on the banks along the Chobe river.

A few White-faced whistling ducks coming to land with a hippo in the background.

A Wire-tailed swallow with its shiny dark blue upperparts, black eye band, chestnut brown crown, white throat and no collar. This species is named for the very long filamentous outermost tail feathers, which trail behind like two wires.

A Water thick-knee bathing in the shallow water at the edge of the river.

An adult Fish eagle in flight scanning the water below for potential prey close to the river’s surface.

A Spurwing goose running to take off and in the process leaving a trail of water splashes.

The annual floods start in March and peak around June in the winter months. This is a time when a myriad of newly spawned bait fish make their way back into the river, only to be ambushed by shoals of hungry Tiger fish and Catfish waiting for them. That is just what the Fish eagle’s are waiting for.

Two pairs of the diminutive Pygmy geese feeding in a secluded part of Jacana alley just off the northern channel of the Chobe river around Sedudu island.

The Pygmy geese seem to be around all year round. They are skittish with the female taking off before the male. We call them “pocket rockets” for a reason.

A Red-billed spurfowl had come down to drink at Elephant Valley with its dark brown plumage and distinctive red bill and yellow eye ring.

On the river bank near Puku flats we found a flock of Blue waxbills with members of the flock flying down in relays to drink at the river’s edge.

An Openbill stork finding plenty of snails to feed on in the shallow waters near Puku flats.

This Openbill stork skillfully cracked open the snail shell and swallowed the succulent, rich inner parts.

Winter time seems to be a time when we see more Comb or Knob-billed ducks along the Chobe river. The female does not grow a comb but does have the iridescent colours on its secondary wing feathers adding that little bit of pazazz.

It is cool in the winter mornings along the Chobe, so this Fish eagle was taking the opportunity to warm up and dry its wings in the morning sun high up on top of a tree overlooking the river.

An African skimmer hunting in the late afternoon rippled waters of the Chobe river. Perfectly adapted for scooping up small fish which have come to the surface to catch insects. The black feathers on crown, around the eye and neck are thought to reduce the glared from the water.

The African skimmer has a half wing beat as it flies just above the surface of the river with is lower mandible in the water ready to scoop up a small fish. There must be a reason for the bright red beak but I have still to find out what it is.

The high power to weight ratio and the precision flight make the hunting of the African skimmer spellbinding. They mostly rely on their sense of touch through their bills. If the prey is too big or the object too solid the skimmer’s head recoils downward underneath its body to release the beak from the object. Skimming usually takes pace in the early morning or late afternoon when the water is calm.

Not on the boat this time, but we sitting having breakfast at the Chobe Safari Lodge when we heard the unmistakable cries of the Trumpeter hornbill. A small family flock were feeding on the fruit of a tree in front of the lodge at the river’s edge.

The Trumpeter hornbill makes a loud wailing , nasal call which sounds like a baby crying. The large casque is a sign that it prefers dense woodland areas. They tend to flock outside breeding season.

This coucal was issuing, as Douglas Livingstone puts it “the rainbird’s liquid note” from the sand bank of Sedudu island around mid-morning. The call sounds like “sound of water bubbling from some cool spring hidden deep in the bush. This looks like a Senegal coucal as it lacks the fine barring on the rump but could be a Coppery-tailed coucal as I could not see the full extent of its tail. Both are common residents in this area. This was a solo act we did not hear the duet in this episode.

Reed cormorants are agile, highly successful fisherman in the fish rich waters of the Chobe river.

An active and successful Reed cormorant with a tasty morsel.

We found a small family herd of giraffe down near Chobe Game Lodge. They were eating soil rich in minerals in a what is called geophagia. In this case the soil looked to be rich in a form of chalk. While the giraffe were occupied it was a perfect time for the Red-billed oxpeckers to get to work grooming, cleaning and feeding from their host.

The Fish eagles were active. Some watched from a perch on a tree high above the river while others stood on the river bank. As the water gets colder the fish tend to swim deeper in the river. This dictates that the Fish eagles must become more opportunistic which mean mongoose, Jacana and White-faced whistling duck come onto the menu.

A male Stonechat was on the look out from a tassling reed.

A Collared pratincole disturbed by a herd of buffalo walking along the sand bank it was roosting on Sedudu island.

A Collared practincole seeking protection from the cool wind one morning on the north side of Sedudu island.

This was a first in Chobe for me, I had not seen a Curlew sandpiper along the Chobe before. It is a migrant but does winter in Africa and breeds in the tundra of Arctic Siberia.

I assume it was a Curlew sandpiper from the decurved shape of its beak, the cryptic colouration of its back and its white breast.

A lone Kittlitz plover on Sedudu island not far from the Curlew sandpiper.

I could not see the tail and rump but I assume this was a Senegal coucal as it looked slightly smaller than its coppery-tailed cousin. It also prefers a dense waterside habitat. Coucals are members of the cuckoo family.

Sunning spots are at a premium in winter. A Reed comorant objected to this grey-heading gull stealing the prime position.

That unique grey face, red eye ring, red beak and red legs are a give away, making this grey-headed gull easily identified.

There seems to be a pair of Fish eagles every couple of hundred metres upstream the Chobe river from the rapids below the Mowana Game Lodge up river to Serondela. We did not go much further past Serondela due to the distance from our base at the Chobe Safari Lodge.

An adult African spoonbill flying back to its roosting site in the trees in the Chobe river rapids just above Kazangula.

This female Comb duck had to had to make last minute adjustments to its landing due to the crowded land area.

Bird photography on the Chobe river is a highly productive. This was mid-winter so all the migrants had left for warmer climes. The permanent water and rich fishing makes this an ideal residence for waders, storks, ducks, geese and raptors.

“A great photograph is one that fully expresses what one feels, in the deepest sense, about what is being photographed.” ~ Ansel Adams

The few images I have shown in this post is just a selection of the birds we saw along the Chobe river. I had already put out a post on egrets and herons and another on kingfishers. We had such good sightings of pratincoles that I will do a separate post of collared pratincoles.

Chobe’s river horses

Along the Chobe river between the rapids below Kasane up river to Serondela is home to numerous pods of hippos. The river is flowing all year round which is ideal for them. The high water period is around May-June each year when the flood waters come down from Angola. Hippos do not swim but rather walk, prance, and even “fly” underwater. They can float or sink by controlling their breathing and body position. Parts of the hippo’s skeleton have very dense bones. This bone structure acts as a form of ballast to enable them achieve neutral buoyancy underwater. They are able to further regulate their buoyancy by controlling their breath. Breathing out creates negative buoyancy.

“Everything you see exists together in a delicate balance.” ~ The Lion King

Hippopotamuses get their common name from the ancient Greeks and which literally translates into English as river horse.

“It’s not what you look at that matters, it’s what you see.” ~ Henry David Thoreau

Female hippos are highly protective of their calves even against much bigger male hippos. We found many hippos out of the water but this was because we were on the Chobe in June which is mid-winter in the southern Africa. During the day when the sun is blazing, hippos spend most of their time in the water to keep cool and prevent them from sunburn. They do like to lie in mud baths next to the river which offers some protection from the sun. Hippos also produce a red fluid which is a deep red mucus-like secretion which helps to control their body temperature and acts as a potent sunscreen and antibiotic.

This looked to be a young male trying to mount a large female hippo with red-billed oxpeckers in attendance. Hippos tend to fight a lot and many have scratches and cuts on their thick hides which the oxpeckers clean up. This young male did not look like he was making the slightest impression on the dozing female. It was winter in southern Africa so the hippos spend more time than usual sunning themselves on dry land to warm up.

Hippos usually mate in the water. The female hippos are often forcibly submerged in the water by the male hippo for most of the mating process. She needs to come to the surface at times to breathe. In some cases, although very rarely, the hippos may choose to mate on land.

 A hippo can run at 30 kilometres per hour and will charge anything that gets in its way, especially if you are between it and its place of safety, which is the water. We had one incident along the Chobe river several years ago when we got between the water a dozing bull hippo. He was dosing about 40 metres from the water’s edge in the grass. We stopped next to the bank to photograph some waders. We were between the hippo and the water but checked to ensure the bull hippo was relaxed and dozing. It was not until Lou Coetzer, our CNP Safari guide, shouted to the boat driver to get out of the way as quick as possible when we turned to see the bull hippo in full charge toward the boat. We made it but a matter of metres. In our shaken state, we were reminded never to be complacent. When hippos run for the water it does provide photographers with opportunities to capture spectacular splash shots as they charge into the water.

“Hippos always have the right of way, except when an elephant crosses its path.” ~Mike Haworth

There were other times when we were slowly boating through the thick matt of water lilies and water grass when out of nowhere a hippo burst out of the water. The guide and boatman kept a very wary eye on the movement of hippos as we are travelling along the river. You would be surprised how quickly a hippo can move through the water. Furthermore, do not be fooled by deep water they can run and bounce of the river bed surprising fast and continue the chase for longer than you might expect.

The biggest threat to a male hippo is another male hippo. This young male was not being allowed back into the water by the dominant bull who was not about to shy away from a confrontation. Most hippo fights take place in the water. Hippos live in pods or groups ranging from – on average – 30 individuals to bloats numbering up to 200 in the Luangwa river. Pods comprise females, their young and a single dominant bull. This bull will aggressively protect his females and territory against other male hippos. He won and maintains his dominant position through continue combat and confrontation.

The open jawed “yawning” display is usually a threatening posture. When an unwanted male enters the dominant bull hippo’s territory, the two size each other up. They will probably stand nose to nose and bellow their discontent. In an attempt to threaten each other they open their jaws as wide as possible, which can be as much as 150 degrees wide, to display their size and power as well as their sharp teeth. If that does not work it can end up in a pitch jaw battle. The hippos teeth tend to sharpen naturally through constant use throughout their life, and can grow to be up to three feet long, strong enough to cut deep into the opposition’s thick hide or the hull of an aluminium boat.

A typical family scene along the Chobe river in winter. The larger females and males are lying in the mud in the sun. The youngsters and younger females, probably mothers, got up when we passed by. The females were probably just protective of their youngsters. The hippos do not seem to be fussed about the crocodiles or all the birdlife around them. In this case there were hundreds of Egyptian geese which made a racket but this did not disturb the slumbering mud bathers.

“Only let the moving waters calm down, and the sun and moon will be reflected on the surface of your being.” ~Deepak Chopra

After the mating period, the female hippo has a long gestation period of around eight months and the birth usually takes place in the wettest season of the year. When it is almost time to give birth, the female hippo isolates herself from the pod until she has given birth to her calf (female hippos usually give birth to one calf but occasionally produce twins). The baby hippo is born underwater with its hind legs appearing first.

Hippos and elephant don’t usually tangle. This bull elephant had crossed the southern channel around Sedudu island to feed on the island. Hippos are highly territorial but although huge they are way smaller than a bull elephant. Elephants are not usually aggressive animals unless there are young to protect or water or grazing that they need to protect. Interestingly, this bull hippo did not give much ground to the confronting bull despite its major size and weight disadvantage. Thankfully the confrontation was over quickly with no damage done.

Nothing looks more relaxed and content than a hippo submerged in its salad. This hippo was neck deep in the river amongst water lilies and water grass. The late afternoon light was soft and warm and this hippo seemed to enjoy being adorned with water lily pads.

Hippos spend most of their time deep in water to cool and graze on the water grass in the river. They require about 45 kilograms of food a day to maintain that massive weight. Hippos are herbivores but their diet depends on what is available. Hippos generally do most of the grazing at night on land but along the Chobe the overgrazing by elephants has dictated that hippos have adapted to take advantage of the water lilies and water grass. Hippos are ruminants but have only three chambers to their stomach, not four as in other ruminants. Hippos do not chew the cud, a ball like mass of partly digested plant matter. The hippo also has a small and large intestine. The small intestine is where all the fats, proteins and fat are digested (or emulsified) by enzymes and absorbed. The large intestine has the function of absorbing the water that goes through it and excretes whatever bodily material is left over as defecation.

Like elephants, hippos are the gardeners of Africa’s river systems. Hippos keep channels open through the reeds and papyrus which improves the flow of the river. Hippos defecate a lot but this provides vital for food for the fish. In turn the fish feed the Catfish and Tigerfish and many waterbirds. The Catfish and Tigerfish in turn feed the Fish eagles and crocodiles. There is a trophic cascade.

“Few can sojourn long within the unspoilt wilderness of a game sanctuary, surrounded on all sides by its confiding animals, without absorbing its atmosphere; the Spirit of the Wild is quick to assert supremacy, and no man of any sensibility can resist her.” ~James Stevenson-Hamilton

Chobe’s Chacma characters

“What is it that awakens in my soul when I catch the scent of rain, when I see the sun and moon rise and set on all the colours of the earth, when I approach the heart of wilderness? For indeed something does move and enliven me in my spirit, something that defines my very being in the world, I realise my humanity in proportion as I perceive my reflection in the landscape that enfolds me. It has always been so.” ~ N. Scott

Along the Chobe river upstream of Kasane to Serondela there are several troops of baboons. Two primates are found along the Chobe river, the Chacma baboon and the Vervet monkey. Baboons are Old World monkeys. There are five extant species of baboon – olive, yellow, Chacma, Guinea and Sacred or Hamadryas – and all are found in Africa and there is a population of Hamadryas baboons found in Saudi Arabia.

The word “chacma” is derived from the Hottentot (Khoikhoi) name for baboon, namely chocchamma or chow kamma.

Chacma baboons are found throughout southern Africa and along the Chobe river. They are the largest and most terrestrial monkeys found in southern Africa. These baboons are highly social and can live in troops as large as 100 individuals. The troops I have seen along the Chobe river probably number up to 40 to 50 individuals. The next images is of a mother with her two youngsters sitting down on the sandy beach at Pygmy Geese bend on the Chobe river. It was early morning and the sun had just risen. The whole troop had come down from the trees where they sleep at night to avoid most nocturnal predators- except leopard. Grooming is an important social activity that strengthens relationships among a troop. Male to female grooming is used during courtships and nursing. Females partner with certain males for protection, especially for their infants.

On our second morning out on the photographic boat we heard a great commotion. A whole baboon troop was in a large Natal Mahogany near the river’s edge upstream from Pygmy Geese bend. This large tree was probably their sleeping quarters the previous night. Chacma baboons are diurnal meaning they only move around and feed during the day. There was a great deal of barking from many of the baboons. The reason for their alarm calls was that there was a pride of lions near the river’s edge not far from the Natal Mahogany in which they were seeking refuge.

Chacma baboons do not have prehensile tails but they do help with balance and can be great play things for young baboons. Chacmas have wonderful balance, a skill won with age and practice.

Chacma baboons have incredible balance and immense strength. They appear to have great strength in their feet, hands, arms and legs. Although they are not heavily built, except the large adult males, they must have exceptionally strong tendons.

Baboons are dimorphic meaning the males and females are quite different in size. The males are significantly larger and heavier than the females and can weigh between 30 and 40 kilograms, almost double that of most females. The males have long (around 5 cm), razor sharp canine teeth and a dark mane on their neck and shoulders. A large male baboon will give a leopardess a hard time and in a fight those large canines can inflict real damage.

Current research into baboon behaviour has some important things to tell us about how we got so far in the smarts business. After closely observing baboons in the Okavango Delta for many years, behavioural scientists Dorothy Cheney and Robert Seyfarth discovered that they (the baboons) spent much of their time gossiping and eavesdropping on others of their troop. While they had only 14 types of vocalising or “words”, their responses to these words and the movement of the troop indicated that they held in their minds many more concepts for which they had no words. Studies on baboons and other apes, including chimps, show that they all have considerable ability to form ideas and discern and remember sounds, but no ability to represent them. A language of mind has structure and requires that the thinker has a sense of self and of their separation from others and the world. Baboons have this, which makes them such fun to watch, but they live in the present tense. They lack the insight to imagine a different world. Or to change it. (Source: Daily Maverick)

Chacma’s have fascinating social structure and able to communicate via facial expressions, gestures and vocalisations. A baboon troop can and will operate cooperatively against a predator during the day especially a leopard. They develop friendships and misbehaving is swiftly and noisily dealt with.

A fundamental part of their development is their play in and on fallen trees and in bushes. This must be were they develop those strong tendons and learn to balance.

“It is not about achieving your dreams but living your life. If you lead your life the right way, the karma will take care of itself. The dreams will come to you.” ~ Randy Pausch

Gestation period of around 180 days and the females are very protective of the new borns.

Young Chacma’s are very playful. Often they can be very rough with each other but I guess this is part of what toughens them up.

Females carry their very young offspring under their belly. This can be tricky for the youngster especially when the mother is wading through water or drinking. The youngster tends to get dunked frequently.

The belly carrying technique is useful as the mother has her hands free and the youngster can breast feed when ever it likes.

Chacma baboons make wonderful photographic wildlife subjects because they are very active and have so many expressions and poses which we humans can identify with and more often than not find very funny.

“It doesn’t interest me where or what or with whom you have studied. I want to know what sustains you from the inside when all else falls away. I want to know if you can be alone with yourself, and if you truly like the company you keep in the empty moments.” ~ Oriah Mountain Dreamer

“There was an ape in the days that were earlier,
Centuries passed and his hair became curlier;
Centuries more gave a thumb to his wrist—
Then he was a man and a Positivist.” ~ Mortimer Collins

Around mid-morning we found a troop that had come down to drink from the Chobe river. The baboons seem to enjoy the Elephant Valley’s little beachfront, where they can slate their thirst and rummage through the elephant dung for undigested berries, seeds and other edibles. Elephants digest their food with less than 50% efficiency. Elephants are non-ruminant herbivores so do not chew the cud, ruminate or belch like ruminant animals.

Baboons can often be found foraging or drinking with antelope such as impala and kudu. Both species benefit from more eyes, especially as drinking from the Chobe river delivers threats from predators on land and in the water. The Chobe river is infested with crocodiles some of which are many years old and massive and wily hunters.

This was one of the older adult females who had come down to drink at the river’s edge. You can see that they watch the water very carefully for any sign of an incoming crocodile. The baboons prefer to drink from small pools of water near the river’s edge because of the reduced threat of a crocodile attacks but if there are no pools they have to drink from the river.

An example of a very young baby getting wet while its mother was taking a drink from the river.

Once the youngsters are strong enough they can ride on their mother’s back. They seem to really enjoy the ride and climb on and off with gay abandon.

There is still so much in the world worth fighting for. So much that is beautiful. So many wonderful people working to reverse the harm, to help alleviate the suffering. There are so many people dedicated to making this a better world. All conspiring to inspire us and give us hope that it is not too late to turn things around, if we all do our part.” ~ Dr. Jane Goodall

A partial backlit shot of a female Chacma picking up edibles from the water. This is an extremely dangerous place to be feeding, especially as she was already in the shallow water. An opportunity for a crocodile. We never saw a croc attacking a baboon while it was drinking, but it does happen.

Baboons will eat many things varying from the new shoots on trees and bushes to flowers, fruit, seeds and berries to water lily shoots. They will all eat birds eggs and even spiders and scorpions when they can find them. They often stuff there cheeks full of food to eat later when they feel safer.

This young Chacma was gorging itself on water lily shoots but obviously keeping a wary eye out for crocodiles.

Chacma baboons exhibit many vocal signals, which can be combined with visual signals. They use a well known double bark called “bokkum” as an alarm or aggressive signal; it’s given by only high-ranking males when there is aggression either between troops or within their troop. It is also used for a predator signal or for when a male communicates his presence or arousal. Lower-ranking males use a shrill single bark. This is expressed when there is a sudden disturbance or when one part of the troop rejoins another. Grunts are used for contentment, desire, or mild aggression. (Source: New England Primate Conservancy).

As photographer we can spend hours watching a troop of Chacmas moving along the river’s edge, there is always something happening whether it is youngsters playing, a teenager getting disciplined or the dominant male asserting his authority over the troop.

“The earth does not belong to man; man belongs to the earth. This we know. All things are connected. Whatever befalls the earth befalls the sons of the earth. Man did not weave the web of life; he is merely a strand in it. Whatever he does to the web, he does to himself…” ~ Chief Seattle
