Helmeted Friarbird, Philemon buceroides. Common in dry forest around the tropical Australian and Indonesian coast, relatively large (about 40 cm) and with a variety of raucous calls that are a feature of the tropical dawn.
Olive-backed Sunbird, Cinnyris jugularis; female. A tiny (10cm) mainly nectar eating bird - in this case nectar of the Umbrella Tree, Schefflera actinophylla - native here but a weed in many areas outside its original home.
Both Z50II with 28-400 @400mm with cropping. Bird recognition works quite well on the Z50II.
