Congregation of several of this species at a gravel pit area where soil & rock had been excavated for road construction.
At a certain altitude, there was an abundance of this tree. Amazingly prolific blooms.
Duiker dung. There are two options on Bioko: blue (smaller) & red (bigger). The pellets looked 'big' to me, for whatever that's worth. Maybe red?
Crappy pictures and I'm not 100% confident of ID, but in support of a palm-nut vulture ID: (a) face looks like it has some color, (b) tail is relatively short, and (c) I saw several other palm-nut vultures on island (and one hanging dead for sale).
Caught in a pit trap. Yellow belly.
Seen on a busy Malabo street, roosting in palm trees. Possible that these are Rousettus (either R. aeyptiacus or angolensis) but a Google image search looks like it better matches Eidolon helvum.
In flight. Not all seen in photo, but was a group of 6 (which is apparently somewhat unusual to see more than a pair together).
Caught in a pit trap. Reddish base at back leg.
Various individuals--will confirm with local expert that they're all the same species.
Yellowish montane bird.
Banded bird (by BBPP): either N. minullus (shorter, less decurved bill compared to other options) or N. chloropygius (my best guess) or N. reichenowi
Not sure what occurs this high that would leave this dung: a blue duiker? a giant rat?
The only option for a yellow-bellied male sunbird on Bioko?
soaring near the top of Pico Basile
Not 100% confident of ID (the photo was taken of 4 parrots flying relatively high & far away), but the gray parrot may be the only option for Bioko. To support this ID, I can make out a reddish tail, and can confirm that they were flying like parrots.
