Buffy-fronted Seedeater

Small and streaky flycatcher, with longer-winged appearance than Asian Brown and Dark-sided Flycatchers. Breeds in mixed and deciduous forest in lowlands and hilly regions. Dark brown above, white below, with distinct pale eyering and long, dark streaks below. Streaking can resemble the patterning of some Dark-sided Flycatchers but is more distinct, less smudgy-looking. Asian Brown Flycatcher shares the same general color scheme but is paler brown and lacks streaking.

Fairly small fork-tailed hummingbird of lowlands. Males have an iridescent green head and breast and a violet belly, but in poor light appears evenly dark overall. Females are green above, light gray below. Note the slightly drooping bill on both sexes. One of the most common hummingbirds in lowland Amazonia; found in a variety of open forested habitats from young rainforest and forest edges to treefall gaps and gardens.

Large, dark swallow. Distinctive north of Mexico, where it is the largest swallow. Adult males are dark overall with a purplish-blue iridescence visible at close range. Females are grayer with iridescence on the crown and back, and variable splotchy patterning on the underparts. Immatures lack any purplish color and have a whiter belly. Gives a distinctive liquid gurgling call. In the eastern U.S., nests exclusively in nest boxes and martin houses; also uses natural cavities in parts of the western U.S. and Mexico. Departs breeding grounds in the late summer, locally staging in massive numbers. Winters primarily in the Amazon basin of South America. During migration and winter, identification is complicated by several other extremely similar species of martin. Identification features are not well known; some are best left unidentified.
