Southern Nutcracker
Nucifraga hemispila
Large, distinctive corvid, roughly the size of a Eurasian Jay. Note the long and heavy bill, white-flecked face, and black cap. Note unspotted dark brown back and sides. Short tail, white vent, and white tail markings evident during undulating, woodpecker-like flight. Inhabits coniferous and mixed forests, from lowlands up into high montane forests. Often stores nuts for the winter. Mostly resident but large numbers may irrupt periodically out of the normal range in response to food shortages. Gives a variety of calls, especially during the breeding season, including harsh grating rasps, as well as quieter “mumbling” calls and mimicry. Formerly grouped with Northern Nutcracker under the more generic “Eurasian Nutcracker.”

Leaden Flycatcher
Myiagra rubecula
A long-tailed, slender songbird with fine bill. Males rich blue-gray above, white below, with a blue-gray bib with convex lower edge (curves upward at the edges).

Song a repeated two-note whistle; call a loud buzzing “zerp.”

Male similar to male Shining Flycatcher, but Biak is found in forest rather than waterside thickets and is smaller and less glossy. Often found in pairs and female has gray rather than rufous upperparts. Voice, a simple up-and-down whistled song and raspy call.
