Distribution
See taxonomy.
Now found annually in the Great Lakes and Atlantic Coast regions in November.
Taxonomy
It has been proposed that it should be split into two species, but at present most authorities do not recognize this split:
- (Mexican) Cave Swallow (Petrochelidon pallida): Nest in northern Mexico and the US states of New Mexico, Arizona, and Texas. Most spend the winter in or near El Salvador, but a few stay in S. Texas and north-central Mexico. Monotypic.
- Cinnamon-throated Swallow (Petrochelidon fulva): Nest in the Caribbean, southern Florida and southern Mexico. Resident in Puerto Rico, Hispaniola, and Jamaica, but other populations are mostly migratory: absent from Florida and mostly absent from Cuba during winter, while the winter range of the southern Mexico population deserves further study. Includes subspecies citata, cavicola, poeciloma, and puertoricensis.
Data from mtDNA suggest this split may be more appropriate if including citata from southern Mexico as a subspecies of P. pallida, and thereby essentially ending up with a western (P. pallida) and an eastern species (P. fulva).
Has been known to hybridize with the Barn Swallow and may be better included in the same genus, in which case it would become Hirundo fulva. If this is accepted, race pallida (or species, if following the split) must be renamed pelodoma, as the former name is preoccupied in the genus Hirundo. However, DNA data indicate that the genera Hirundo and Petrochelidon are not each others closest relatives.
Habitat
Open areas near water.
Behaviour
Diet
The diet includes flying insects.
Breeding
They nest colonially building a cup nest from mud, lined with grass. The clutch consists of 3-5 white eggs with dark spots.
