Javan Owlet

Glaucidium castanopterum

Chunky small owl with a big rounded head. Note finely barred head, bright chestnut back and wings, and white underparts marked with long brown streaks. The only owlet on Java; shape and coloration eliminate any scops-owl. Unlike Collared Owlet, this is a primarily nocturnal species, only rarely remaining active through the day. Inhabits forest and forest edge from lowlands up into foothills. Song is a barbet-like series of trilling barks which accelerates rapidly before ending suddenly.

Rufous-tailed Flatbill

Rufous-tailed Flatbill

Ramphotrigon ruficauda

Smallish flycatcher, characteristic of forests on sandy soils and seasonally flooded forests. Heard more often than seen. Best told by bright rufous tail and flight feather edges contrasting with greenish-brown body. Singles or pairs inhabit the mid-story of tall forest and typically do not associate with other species. Sits upright and sallies to foliage for insects. In western Amazonia, told from Dusky-tailed Flatbill by clearer (less mottled) breast and extensive rufous in wings and tail. Voice is a single, lazy whistle, with characteristic strong inflection in the middle.

Black-fronted Ground-Tyrant

Black-fronted Ground-Tyrant

Muscisaxicola frontalis

Breeds locally in the high Andes of central Chile and adjacent Argentina; migrates north in winter. Favors bleak rocky and stony slopes, adjacent bogs, and lakeshores; often in same areas as other ground-tyrant species. Subtly distinctive with rather ashy gray plumage, droop-tipped bill, and black “mohawk” head pattern. Often looks more pot-bellied than other sleeker ground-tyrants.

Collared Petrel

Collared Petrel

Pterodroma brevipes

A small gray-and-white petrel with a dark hood, a bold dark “M” pattern across the upperwings, and a distinctive bold black underwing pattern. Very variable. A pale morph resembles Gould’s Petrel, while a distinctive sooty-brown dark morph shows exceptionally bold underwing markings. Pale morph separated from Gould’s Petrel by its much bolder underwing pattern and its hood, which often meets below the neck, creating a full collar. Silent at sea.
