A last ID request for the moment! I think this was in one of the smaller aviaries near the Scripps Aviary, but I'm not wholly sure. As always, help gratefully received..... (from July 2017)
I' ll take a shot. A Baglafecht Weaver (Reichenow Weaver). The bird usually looks more yellow, but the lighting and green background could be giving us a more orange tone. The black around the eyes varies, but I ws able to find photos that match the bird above. Beak shape matches pretty well as well as eye color and shape. That's my best guess and I know the zoo has had this species in it's collection and in the Lost Forest.
@lintworm and @timmychompchomp - thank you very much for your help. Timmy: any idea where in the Lost Forest these are maintained? might this have been in the Scripps Aviary (I thought this was where the Reichnow's Weaver was to be seen)?
