Slaty Flowerpiercer

A small flycatcher with a small range in eastern Panama and barely into Colombia. Look for a combination of bright yellowish-olive underparts with bold yellow wingbars and a white eyering. Rather slender overall with a long tail and a narrow bill. Sexes alike. Occurs in foothill forest from around 900–2,000 m, where singles or pairs are often found following mixed-species flocks in the canopy. Listen for high-pitched sputtering calls.

Restricted to the Azores, Canary Islands, and Madeira. Slightly bigger than European Serin and yellow-green overall with a pale bill, and a dark forked tail. Has a streaky rump, but this can be hard to see. Males are greenish-yellow below while females are duller and grayer on the breast and neck. The song is very melodic and rich. Found in forests, plantations, gardens, and orchards, sometimes gathering in flocks. Introduced to the Midway Atoll, where coloration ranges from unstreaked bright yellow to almost white.

Beautiful sparrow with gray upperparts, and black mask and crown separated by a white stripe. Similar to male Collared Warbling-Finch, but breast band is smaller, face stripe does not reach past the front of the eye, and tail lacks white. Inhabits the understory of dry and semi-humid forest. Vocalizations are generally high-pitched: song consists of a few wheezy whistles followed by a quicker trills; most common call is a simple “tink” note.
