Pale-throated Wren-Babbler

Slow-moving and highly elusive chunky Javan endemic, found only in montane and foothill forests. Generally scarce and difficult to pick out in the dark forest due to its coloration and inactive behavior. Males are entirely blue, with some paler highlights on the crown and wings. Female has a mostly dark brownish body with blue most evident in the wings, tail, and crown. Combination of size, shape, and behavior serve to distinguish this infrequently-encountered species from other dark blue forest birds, such as Javan Whistling-Thrush and the Javan subspecies of Sunda Robin. Vocalizations include high, thin whistles and harsh chattering.

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.

Medium-sized owl (but large for a screech-owl) with short ear tufts and brownish (not yellow) eyes. Fairly common in scrubby woodland, thorn forest, and edge of interior southwest Mexico where it is endemic. Sometimes seen hunting beside quiet roads. Usually detected by its gruff, bouncing ball song. Mottled Owl occurs in same areas but is slightly larger, with a rounded head and thicker dark streaks below.
