Red-throated Swallow

Petrochelidon rufigula

A small, stocky, martin-like swallow that has dark upperparts mottled around the hindneck and back, rusty throat with an indistinct partial dark collar, and a paler buffy belly. In flight, rusty rump and white blotches in the tail are distinctive. Pairs and small flocks are residents and partial migrants foraging over open grassland and rivers, often nesting on cliffs, buildings, or bridges. Calls include a high-pitched twittering, especially at colonies. During May to August overlaps with intra-African migrant South African Swallow, which is very similar to Red-throated Swallow, but is larger and bulkier, lacks white in the tail, and has dark breast mottling forming a smudgy collar.

Colinus virginianus

Small and rotund with intricate brown, black, and white patterning. Some striking variation in plumage across range. Most males, including those in the eastern U.S., have bold black and white head pattern and heavy white spotting on belly. In Mexico, males can be entirely cinnamon-colored below and have a fully black head; some might have a white eyebrow or a dark chest band. Females are more consistent throughout range: look for buffy throat and eyebrow. Pairs or small groups are found in scrubby fields and brushy woods. Usually on the ground, but occasionally perches in trees when singing. The only quail native to the eastern U.S., where populations are declining sharply. Listen for distinctive “bob-WHITE!” whistle.
