Citrine Warbler

A medium-sized, short-tailed sparrow. Extensive plumage variation across range, but always streaky. Usually shows distinctive yellow patch in front of eye, but this can be indistinct or absent on some individuals. Some populations in California and Baja have larger bills and more muted gray streaking; others are very dark and boldly streaked. “Ipswich” Sparrow on the Atlantic Coast is paler with unique buffy-pinkish tones. Almost always found in open areas, from meadows and hayfields to tundra and coastal dunes. Tends to be found in more open habitats than Song Sparrow; also smaller and shorter-tailed.

An unobtrusive bird with an oversized head and bill. Look for tiger-striped pattern—warm cinnamon-brown overall with uneven black barring. Also note slightly darker cap and staring pale eye. Uncommon; found around forest edge and secondary woodland in the lowlands from Panama to western Ecuador. Perches still for long periods of time, often on an exposed perch. Frequently detected by distinctive wolf-whistling calls.

A medium-sized flycatcher with strikingly different male and female plumages. Male is beautifully colored, with deep blue upperparts, mostly orange underparts, and a white belly. Female is much duller, with a grayish head, gray-brown wings, a rufous tail, and rufous underparts. Scarce and local in the understory of hill forest. Song is jumble of melodious warbling and whistling notes. The calls are loud “chek” or “sit” notes, and are often mixed into the song. Similar to Bornean Blue Flycatcher, but darker, especially on the belly (in both sexes) and back (in the male). Also similar to Sunda Blue Flycatcher, but darker overall and shorter-billed. Dayak Blue Flycatcher is further distinguished by the less extensive black chin patch of the male and the rufous rather than blue tail of the female.
