The cliff swallow or American cliff swallow (Petrochelidon pyrrhonota) is a member of the passerine bird family Hirundinidae, the swallows and martins.[2] The generic name Petrochelidon is derived from the Ancient Greek petros meaning "stone" and khelidon (χελιδών) "swallow", and the specific name pyrrhonota comes from purrhos meaning "flame-coloured" and -notos "-backed".[3]
Cliff swallows are extremely social songbirds that can be found in large nesting colonies reaching over 2,000 nests.[2][4][5] They are frequently seen flying overhead in large flocks during migration, gracefully foraging over fields for flying insects or perching tightly together on a wire preening under the sun.[4]
Cliff swallows build gourd-shaped nests made from mud with small entrance holes.[2][4][6] They build their nests tightly together, on top of one another, under bridges or alongside mountain cliffs.[2][4] Living in large populations, these aerial insectivores use extensive vocalizations to communicate warnings or food availability to the other individuals.[4]
