Birdsong field guide
Peruvian Martin
Progne murphyi
The Peruvian Martin is a large, range-restricted swallow endemic to the arid Pacific coastline of South America. It is currently classified as Vulnerable due to its small, declining population and specialized nesting requirements.
What it sounds like
A series of rich, liquid, and gurgling warbles, typically lower in pitch than other members of its genus.
Field notes
- It is one of the least-studied members of the genus Progne, with significant gaps in knowledge regarding its breeding biology.
- Unlike many relatives that rely on man-made birdhouses, this species frequently nests in natural desert cliff crevices and on offshore guano islands.
- The species is sexually dimorphic; adult males are entirely glossy blue-black, whereas females and juveniles exhibit dusky, scaly-patterned underparts.
- The global population is estimated to be fewer than 5,000 individuals, restricted to a thin strip of coastal habitat.
- While primarily coastal, some individuals have been recorded as far as 80 kilometers inland in extreme desert environments.
Habitat
Arid coastal scrub, rocky sea cliffs, offshore islands, and occasionally urban parks or buildings.
Range
Coastal Peru and the extreme northern tip of Chile.
