I'd be grateful for help with the following, all from about ten days ago in the Serengeti (4 ane 5), and Ngorongoro (2) and Tarangire (2 and 3) areas.

1. Waller's or Red-winged Starling? The tail seems too long for Waller's but the eye is red.

2.1 I initially thought was Rosy-breasted Longlaw, but I now wonder if it was Pangani's, even though my field guide suggests it doesn't get as far as Ngorongoro.

3. Is this African Scops Owl?

4. Hartlaub's Bustard?

5. Rufous-naped Lark?

#1 is Fork-tailed Drongo (moulting: old "brown" flight feathers and growing tail feathers): posture is also different from the starlings, more vertical with "less visible leg".

Tom, tu ne penses pas que c'est plutôt une "Hartlaub" ?
Le patron de tête correspond mieux à cette espèce, en imaginant que le noir n'est pas encore nettement exprimé. Le blanc du côté de la tête est plutôt de type Hartlaub. L'arrière du haut du cou est gris,...
Je pense que tu lis sans pb le français
Amicalement

Salut Jean
Je pense que la joue blanche et l'arrière du coup gris ne sont pas des critères très fiables, je recherche surtout les bords blancs des plumes du manteau qui donnent des pointes de flêches très caractéristiques couplées à des centres foncés réduits. Ici aucun 'spike' et des centres noirs très larges. Les tertiaires sont à peine visibles (barrées chez le Black-bellied et uniforme chez le Hartlaub.
I think the white 'thumb' in the face and he colour of the back of the neck are no good features to look for. Hartlaub should show nice white spikes on upperparts (white margins) combined with reduced dark centers. Tertials are hatdly visible (barred in Black-bellied, unifom in Hartlaub)

I still remain confused whenever Hartlaub's vs Black-bellied id threads come up. Maybe if someone were to explain in Swahili?

Ok, now I've taken the trouble to look at a few images I finally see what I think is meant by these spikes! Reckon you'd need to be quite close in the field to assess that feature though? Maybe the tertial differences you mention would stand out more at a distance?? That feature's not mentioned in the East Africa field guide. :smoke:

To say that the tertials are uniform in Hartlaub's, must be a slight exaggeration, but I think this link clearly shows the barred ones in Black-bellied.

This pic also shows the extensive dark centres to upper mantle feathers, which Tib78 taught me in another post.

Further, and also according to Tib78, spotted crown is a good pointer for Hartlaub's - but I don't know if this goes for both sexes and all plumages?

Lika Larry I'm interested in the Hartlaub's vs Black-bellied identification factors.
This link shows "white spikes" and the not barred tertials quite well

Am I getting this right now?

All the best

1. Well yes, they are not boldly barred in Hartlaub's
2. Yes, the link shows all this quite nicely, for even better views of the tertials the bird has to drop slightly the wings
3. YES, we all learned this from thibaut aka tib78
