Verreaux’s Eagle is a large bird of prey that is highly specialised, with its life history and distribution revolving around its main prey of rock hyraxes and preferred habitat of hilly and mountainous terrain. It is wide spread throughout Kenya, especially around Samburu game reserve, Lake Baringo, Lake Magadi and Tsavo West national park. It feeds primarily on rock hyraxes but it also preys on other animals such as small mammals, birds and reptiles. Its populations are stable and have been less impacted by human encroachment due to the isolation and the inaccessible terrain of its habitat.

When perched or at rest adult Verreaux’s Eagles are entirely black in appearance, except for a white ‘V’ above the wings on the back and yellow feet (talons) and cere. In flight, the unfolded wings expose a white rump and whitish panels on the outer wings. The wings have a distinctive shape that is broad in the middle and tapering at the tips. Sexes are similar, but females are slightly larger than males. Juveniles have a yellow-brown plumage and the head and back of the neck have a distinctive reddish-brown colour. The face and throat are black. Juveniles achieve adult plumage in 4 years. The photos appearing here were all taken in western cliffs of Lake Baringo.

Widespread and locally common in higher rainfall areas up to 3000m, though generally uncommon above 2000m. Long-crested Eagle is an adaptable woodland and forest edge species which is especially common in areas partially cleared for agriculture, even when heavily settled. It takes large numbers of rodents and his generally considered beneficial to man.

Long-crested Eagle adult is dark brown or black. It has long white patches at the joint of the wings, visible when perched, forming white lines on each side of the breast. Underwing coverts are white, with black spots. It has broad dark tail strongly barred of white. Tarsi are whitish. Wings are long and broad.
Hooked bill is yellow with dark tip. Eyes are golden or reddish-brown. Feet are yellow with slender talons.

The Cryptic Slender-tailed Nightjar at the Rocky Cliffs of Lake Baringo!

Nightjars are largely nocturnal family. They look like owls, with large heads and eyes and a cryptic plumage. The family name caprimulgidae was given to them after some superstitious belief that because of their wide mouths, the birds suckled goats.

In Kenya we have 13 different species of Nightjars, wide spread in different habitats across the country. The photo appearing above was taken at a rocky countryside of Lake Baringo. Most species are nocturnal or active at dusk, and are solitary and retiring . They concentrate their foraging bouts during twilight hours.

By day, they roots on exposed grounds or rocks, in leaf litter, or on branches. When roosting , they adopt a horizontal posture, in contrast to owls.

Nightjars have very large eyes, adopted to low light condition. They eye have a tapetum, a reflective membrane that increases the amount of light entering the eyeball. Its presence causes reflective “eye-shine” when the eye are illuminated by artificial light.

“The Leopard of the Sky”Crowned Hawk-eagle (Stephanoaetus coronatus)

Although not the biggest eagle in Africa, the Crowned Eagle is considered the most powerful and ferocious eagle based on the size of its prey. Weighing in at 2.5 – 4.5 kg, it regularly kills prey heavier than itself. Forest mammals like Vervet monkeys and duiker (25kg) are never safe when this eagle is near. Africa’s biggest eagle is the Martial Eagle which can weigh over 6kg but prefers to prey on animals like Guineafowl and reptiles.

Also known as the Leopard of the Sky for its hunting abilities, the Crowned Eagle is well camouflaged with bars and blotches on the chest and a slate grey upper side. This colouring makes it disappear in a forest environment, especially because it tends to sit inside the tree canopy instead of on top like most other eagles.

To adapt to the forest environment, the Crowned Eagle has a long tail and broad, rounded wings. The combination of these two makes it extremely agile and fast which is one of the main reasons why it is the only eagle that preys on monkeys actively. Monkeys are very alert and quick, making them difficult to hunt, especially in a group. The male and female Crowned Eagle often hunt as a pair, while one eagle distracts the monkeys, the other makes the kill. With powerful feet and massive talons it can kill a monkey in one blow. This is essential because monkeys have strong hands and can easily damage an eye or a wing of the eagle.

During breeding time crowned eagles become much more visible and vocal as they make undulating areal displays at heights of up to 1km. They can be noisy during these times with a loud ‘kewee kewee kewee’ call from the male. This ritual is normally associated with breeding, but could also be an act of territorial domination.

The nest of a Crowned Eagle is a huge structure of sticks which is repaired and enlarged every breeding season, making the nests grow bigger and bigger. Some nests grow to be about 2.3 metres across making them the biggest nests of all the eagle species.

You have a chance of seeing this species in Kenya if you are touring Mt.Kenya Forest Reser, Nairobi National Park, Aberdare National Park, Kakamega tropical rain forest and Mau Forest.

White-spotted Flufftail at Rondo Retreat Centre, Kakamega forest.

On the first week of December, 2018 we had planned a 8 days photographic trip to kakamega forest. My client opted to stay at Rondo Retreat Centre because of its location right inside the forest. Our target birds were many, but high on the list was the stunning White-spotted Flufftail.

After 3 days of continuous search of this elusive and secretive species, nature rewarded us with great views of both male and female. I guess they were on romantic walk enjoying each other company and failed to notice our presence.

Birding is first class at Kakamega forest, although the forest suffers from increasing fragmentation .

On any bird watching excursion disappointment and  surprises happen all the time, so when my clients and I arrived at one of the forest block a long the lower slopes of Mt.Kenya, seeing a Bar-tailed Trogon was not really in our mind, I guess we had learned to manage our expectation.

On the main trail in the forest other things come by easily without much effort, Mountain Yellow and Brown Woodland Warbler, African Hill Babbler, Black-fronted Bush-Shrike, Yellow-crowned Canary, Abyssinian Crimsonwing, Hartlaub’s Turaco, African Crowned Eagle, Mountain Buzzard, Eastern Mountain and Slender-bill Greenbul, White-starred Robin, Ruppelle’s Robin-chat, Golden-winged and Tacazze Sunbird  among others were some of our priced collection.

Then the big moment come and voila we had some fantastic views of Bar-tailed Trogon. It begun by it calling from a nearby forest thicket  and its continuous calling betrayed its exact location and we had excellent photographic opportunities.

On such kind of trips, sometimes you lose and sometimes you win, but this time round we won in a big way.

Grey Woodpecker (Dendropicos goertae rhodeogaster)

Grey-headed Woodpecker 1Our bird of the week  is the Grey Woodpecker, race rhodeogaster, which is sometimes considered conspecific with the Ethiopian spodocephalus and known as Grey-headed Woodpecker. This species species was photographed around central Kenya.

In Kenya we have 13 species of Woodpecker and they are amazingly beautiful to watch in the field. Most of the woodpeckers we have here are diamorphic, meaning male look different from the female.Grey-headed Woodpecker

Woodpeckers are known for tapping on tree trunks in order to find insects living in crevices in the bark and to excavate nest cavities. Woodpeckers also have, well, a head for pecking. For one, woodpeckers have tiny brains—just 0.07 ounce. The bigger the brain, the higher the mass and thus the higher the risk of brain injury according to biologist research work, hence the reason why woodpeckers don’t get a headache while pecking.

The woodpecker’s strong, pointed beak acts as both a chisel and a crowbar to remove bark and find hiding insects. It has a very long tongue, up to four inches in some species – with a glue-like substance on the tip for catching insects.

While most birds have one toe pointing back and three pointing forward on each foot, woodpeckers have two sharply clawed toes pointing in each direction to help them grasp the sides of trees and balance while they hammer – this formation is called zygodactal feet. Many woodpecker species also have stiffened tail feathers, which they press against a tree surface to help support their weight.

Woodpeckers live in wooded areas and forest where they tap on tree trunks in order to find insects living in crevices in the bark and to excavate nest cavities. Some species drum on trees to communicate to other woodpeckers and as a part of their courtship behavior. Woodpeckers tap an estimated 8,000-12,000 times per day.
