Xavier's Greenbul (Phyllastrephus xavieri). Determinate by call. Elevation: 231 m. Date added to IBC: July 25, 2018.
Detalhes da observação
I am quite certain it is not a Phyllastrephus greenbul and in the case of Icterine and Xavier's it ought to have a paler iris (Icterine), yellow cutting edges on the bill, a longer bill, greyish lores and a bit of a supercilium, and a redder tail though I admit the angle in the image makes that harder to be certain of. It shows very typical proportions and pattern for a Eurillas like Little or Yellow-whiskered with the rather short bill with decurved culmen and I think it shows the small yellow gape that is very typical of Little. The leg colour also looks yellowy/straw/orangey as would be for Little and not greyish as a Phyllastrephus. And the distinct yellow belly contrasting with more olivey flanks of Little also shows well. Xavier's would lack the appearance of a yellow belly patch but just be plainer yellow below (apart from darker breast band if that was visible). It is very yellow around the throat I agree. When I first saw it I thought it might be a Golden Greenbul but I don't believe that would ever show an all dark bill like this and would be more yellow still. And it is indeed odd that it was high up (and sitting out in the open like this) I agree. I'm trying to think if I can persuade myself that perhaps it is a Yellow-whiskered to account for the yellowness of the throat, but not sure I can. I do wonder if this is an immature bird. The pale tips to the lesser and median coverts, and brownish wash to the secondaries. The head shape, size and shape of bill and leg colour all point to Little as far as I am concerned. Also, the back and upper tail appear concolorous, which they wouldn't in X's. Granted, sitting out in the open like that is unusual for Little and it looks rather more yellow below than one might expect, but Jeremy's assessment that it is an immature might help to explain this.
