I’ve been studying raptors (birds of prey) in the Athi-Kaputiei Ecosystem of southern Kenya for a few years now and recently published a paper on the findings of my research so far in SCOPUS: Journal of East African Ornithology. In the paper I share a lot of info on the abundance, distribution and status of raptors in the area. Being a scientific publication however, the space available for photos was limited. I’d therefore like to share more photos of the raptors I’ve recorded as a way of highlighting the beauty and diversity of the raptors, and wildlife overall, in this incredible but highly threatened part of Kenya. The paper focuses on resident raptors but here I include photos of migrants as well. All photos were taken within the greater Athi-Kaputiei Ecosystem. Names used here follow the Checklist of the Birds of Kenya – Fourth Edition (Bird Committee, the East Africa Natural History Society, 2009). I’ve also included alternative names for some birds.
Falcons (Falconidae)
Common Kestrel Falco tinnunculus
Male of the Palearctic migrant race F. t. tinnunculus in Olerai ConservancyF. t. tinnunculus female – Olerai Conservancy
Lanner FalconFalco biarmicus
A juvenile near Swara Plains (Game Ranching)
Peregrine FalconFalco peregrinus
The only photo I ever managed of a Peregrine in the entire area. Not exactly award-winning! They are hard to find and even harder to photograph! This one is an adult from a pair of the resident race F. p. minor.
Diurnal Birds of Prey other than Falcons (Accipitridae)
Secretarybird Sagittarius serpentarius
An adult on the prowl in Nairobi National Park Sub-adult attacking prey. It was unsuccessful on this attempt. They are however lethal predators, capable of tackling an impressive array of prey including scorpions, snakes, rodents, hares and hedgehogs.

African Black-shouldered Kite Elanus caeruleus
The bright red eyes of this kite are striking!Hunting individuals are entertaining to watch as they hover in search of preyTalons ready to engage
Black KiteMilvus migrans
The Afrotropical race M. m. parasitus (also called the Yellow-billed Kite) is common in towns and other human settlements.An adult of the Palearctic migrant race M. m. migrans gliding high over Olerai
African Fish EagleHaliaeetus vocifer
Adult male perched along the Empakasi (Mbagathi) River Adult from the Hyena/Nagolomon Dam pair in flight – Nairobi National Park1st year (juvenile) at Hyena Dam – Nairobi National Park2nd year bird along the Mokoyeti River – Nairobi National Park
White-backed VultureGyps africanus
Adult with a full crop after a good feedContrary to popular belief, vultures are very clean birds. The White-backed Vultures of Nairobi National Park bath daily after they’ve had their meal.Drying off after a bath Marabou Storks Leptoptilos crumenifer often join them at the bathing poolAdult in flightImmature bird in flight – Machakos Ranching

Augur BuzzardButeo augur

Tawny EagleAquila rapax
Typical adult – Nairobi National ParkPale adult – Lukenya HillMoulting adult in flight – Olerai ConservancySub-adult in flight – Silole SanctuaryTogether with White-backed Vulture in Machakos Ranching. Both have full crops so had clearly fed recently. Tawnys scavenge regularly and often associate with vultures at carcasses, making them one of the most vulnerable eagles to secondary poisoning (the main cause of the steep decline of African vultures).

Verreaux’s Eagle (or Black Eagle)Aquila verreauxii
As seen from above. Hunting for hyraxes on the rocky slopes of Lukenya Hill. This massive unique-looking eagle is one of my favorite birds.
African Hawk EagleAquila spilogaster

Martial EaglePolemaetus bellicosus
Adult male in Nairobi National ParkAdult female from the NNP pair – Silole SanctuaryMale checking out a potential branch to add to a new nest they were building …… decides the branch is suitable …… breaks it off …… and takes it to the nest.A juvenile in Olerai Conservancy
Barn Owls (Tytonidae)
Barn Owl Tyto alba
Roosting adult
Typical Owls (Strigidae)
Spotted Eagle OwlBubo africanus
This individual had an injured left eye. Very possibly from having stones thrown at it. Persecution as ‘bad omens’ is a major threat to owls in most of Kenya. It’s important to change people’s attitudes towards owls. They are key to healthy ecosystems.
Africa’s largest owl. It can take prey as large as dik-dik, young warthogs and Great White Egret! Though hedgehogs tend to be its favorite prey.A roosting pair
