Alright, this one's for our birding folks on VF:
Thanks, Éric—a really great set of bird photos, thank you!
Eastern Chanting Goshawk, Eastern Chanting Goswack, Mélierax poliopterus

Still our good old Grey-winged Goshawk, which is indeed the Eastern Chanting Goshawk, Melierax poliopterus. In Kenya, there’s no Chanting Goshawk, Melierax canorus—Pale Chanting Goshawk—the English name is misleading.
African White-backed Vulture, African white-backed vulture

Rüppell’s Vulture, Gyps rueppelli, Rüppell's Vulture
? Same

Yes, Rüppell’s Vulture
? Funny position

Rüppell’s Vulture and, I think, African White-backed Vulture, Gyps africanus, White-backed Vulture
Pygmy Kingfisher? Kingfisher... less than 10 cm

Grey-headed Kingfisher, Halcyon leucocephala, Grey-headed Kingfisher—it measures 22 cm (measured the "birding way," from tail tip to beak tip). The Pygmy Kingfisher looks like the Malachite Kingfisher (sometimes called Crested Kingfisher) with a purple patch on its cheek and is just 1 cm smaller at 12 cm.
Von der Decken’s Hornbill, Von Der Decken's hornbill, Tockus deckeni

Yep, and it’s even a male.
Like you, I’m disappointed by the lack of African wild dogs and really surprised by John’s lack of interest. You must’ve been fuming!
Have a great day,
BL
