Pale-throated Greenbul

A long-tailed kingfisher of lowland forests. White underparts and rump, dark blue upperparts with pale blue shoulder and crown. Long white tail with 2 extended central tail feathers ending in spatula tips. Sits still for long periods whilst slowly pumping its tail. Very similar to Little Paradise-Kingfisher, but Common Paradise-Kingfisher is larger, with a paler crown, white rather than blue outer tail feathers and a heavier bill. The safest way to separate, however is by vocalization. Heard more often than seen. Song, a rapidly accelerating and slightly rising series of dry notes.

A relatively large-billed shrike-like bird primarily found in lowland forest canopy. Male is white below and iridescent black above except for a white rump. The female is overall reddish brown, with more reddish wings and a grayish hood. Similar to several bicolored shrikelike birds in the region, but note Sabine’s Puffback’s large bill, striking sexual dimorphism, and unique song, which consists of a distinctive series of long whistles descending in pitch before arriving at a single repeated pitch, growing louder, and then ending suddenly. Songs can sometimes last several minutes, and are more reminiscent of some Yellow Longbill songs than of the songs of other puffbacks. Calls include typical puffback-like rattles and harsh calls. 

The largest of the six prion species, with an exceptionally wide bill that gives the head a chunky appearance. Occurs in dispersed flocks at sea, where it catches prey items either sitting on the water or skimming the surface for zooplankton. Can be seen around breeding colonies on the Chatham Islands, in southern New Zealand, and in the South Atlantic Ocean. The wide bill distinguishes this species from other prions apart from Salvin’s and MacGillivray's, which are smaller in overall size and have a narrower bill than the Broad-billed Prion. However this can be hard to see at sea, and identification of prions is often impossible without a good view or photograph.
