White-throated Blue Swallow

Small and rotund with obvious teardrop-shaped plumes protruding from forehead. Looks gray and brown at a distance, with white streaks on the sides and a scaly belly. Males have black face and longer, more curled crest than females. Usually seen in flocks running on the ground in open, scrubby habitats. Listen for frequent, three-noted call, audible at long distances. Separated from similar Gambel’s Quail by range; also note California has scaly belly with rusty (not black) patch and duller brown crown and sides. Native to western North America including Baja California; well-established introduced populations in Chile, Argentina, New Zealand, and Hawaii.

Tiny, stumpy bird of dense undergrowth. Male is dark slate-blue with broad white eyebrows that give him the appearance of a furious little old man. Female is warm pale brown all over. In areas of overlap with Chinese and Lesser Shortwings, look out for the all-dark lower belly, which is white in those species. Inhabits hill and montane forest, where it forages in dense undergrowth, frequently in proximity to streams. Song is composed of high thin whistles with short bursts of clicking chattering mixed in.

Cryptic, uncommon nightbird of evergreen and mixed foothill and montane forests (900-2000 meters). Both sexes have dappled lichen-like plumage, the male grayish, female rusty brown. Silent birds are best distinguished from other small frogmouths by range, habitat, elevation, and bird’s comparatively small size. Song a long, haunting whistle, given repeatedly in series.
