Pelzeln's Tody-Tyrant

Striking small warbler with bright white spectacles around each large dark eye; a refreshingly distinctive bird in a particularly frustrating group, thanks to its uniquely dark gray head. Active primarily in the lower levels of broadleaf forests in hilly and montane areas with dense undergrowth. Listen for its high-pitched song, typically 1-2 single note or pairs of notes, followed by a rapid musical series of 4-5 notes; averages higher-pitched than White-spectacled and Golden-spectacled Warblers, with less trilling than the former.  

A partridge-like bird with an olive upper body, a mostly gray underside, and broad chestnut bands across the back and wings. Also note the white base to the undertail. Terrestrial, inhabiting forest in lowlands and hills, but most often seen by visiting specific beaches where they come to lay their eggs in the sand at night. The only patridge-like species in range with broad chestnut bands above. Vocalizations, mostly at night, include a moaning “kouw-kouw-kouw” and harsh, agitated “kek” calls.

Mid-sized warbler with a long tail. Dark brown overall, with a white throat and pale eye-line. Found very locally in middle-elevation habitats with a dense ground cover, including bamboo, forest, marsh, and lush grassy areas. Rare species that is not often seen. Most likely to be detected and identified by its distinctive song: a ratcheting up-and-down “dee-ka dee-ka dee-ka…” series which can last for several seconds. Very similar to Evergreen-forest Warbler, and best distinguished by its different song.
