NAME: ‘Rough-winged’ stems from the ‘serrations’ on some wing feathers. ‘Swallow’ refers to the bird’s feeding behavior, by swallowing insects with a wide open mouth while flying. Latin genus name ‘Stelgidopteryx’ refers to the stiff recurved hooks on the wing primaries. Latin species name ‘serripennis’ means ‘saw’ and ‘wing’, again in reference to another wing feature.
HABITAT: Open country near water (river banks, lakes, arroyos), gravel pits.
DIET: Insects caught on the fly.
NESTING: Nest is at end of a tunnel in a vertical surface, may be an old one from a kingfisher at times. Between five and eight white eggs are laid, incubated likely by female. Chicks fed by both parents.
DISTRIBUTION: Breeds in southern Canada and the contiguous USA. Some very rare breeders have been identified in southern New-Brunswick. Winters in Mexico, the Caribbean and Central America.

ON PEI: Does not breed on Prince Edward Island, sightings listed as ‘accidental’ so far in spring, summer and fall. See note below on bird vagrancy.
CONSERVATION: Numbers may have increased locally thanks in part because of nesting in man-made structures. Currently not at risk.
Vagrancy: In biology this means an animal going way outside its normal range. For birds, this can happen when there are storms and they get blown off course. On other times, the bird simply wanders in a different direction than usual. Here’s an article about vagrancy in birds.
