Sumba Buttonquail

Small, distinctive boobook with extensive chestnut-brown barring. Favors surviving primary rainforest, but can sometimes be found in secondary growth; can be found on roadsides through suitable habitat when hunting. The only resident owl on the island; the migratory Northern Boobook is a winter visitor to the island, and is significantly larger and much darker overall, with an all-brown head and brown-striped white underparts. Present species gives an odd, distorted-sounding “qwr-qwerk.” Begging birds give a shrill trill. Unfortunately, like many other Christmas Island species, has suffered declines due to the introduced yellow crazy ant, which has caused the owl to disappear from parts of its range.

A rufous-brown owl with yellow eyes, prominent white eyebrows, and mottled underparts. Juvenile reportedly redder-colored and plainer. Inhabits forested lower foothills, regularly in pairs. A recently described, little-known owl confined to Sumba. Smaller than Sumba Boobook, and separated by yellow eyes, lack of bands on the underparts, and markedly different voice.  Song is a single “woop” note, often given as a duet. One sex calls with a higher pitch than the other.

A medium-sized olive-gray honeyeater with a pale yellow cheek patch and a relatively stout bill. Cheek patch is often a crescent compared to the circular patch on Graceful Honeyeater and the oval path on Yellow-spotted Honeyeater. Adults have a bluish eye, while the similar Graceful Honeyeater has a blue-gray eye and Yellow-spotted Honeyeater has a brown eye. Listen for the rapid staccato machine-gun call of Lewin’s compared to the loud repeated whistles of the Yellow-spotted Honeyeater and the more simple, single note call of Graceful Honeyeater. Of the three easily confusable species, this is the only one found away from the tropics; it occurs in wetter forests and gardens all along the eastern coast of Australia.
