Pygochelidon cyanoleuca
The Blue-and-white Swallow (Pygochelidon cyanoleuca) is a striking, agile aerial insectivore widely distributed across the Americas. Measuring approximately 12-14 cm (4.7-5.5 in) in length and weighing around 10-15 grams (0.35-0.53 oz), its most distinctive field mark is the stark contrast between its glossy, iridescent blue-black upperparts and pure white underparts. Its short, slightly forked tail is also characteristic. Taxonomically, it belongs to the swallow and martin family Hirundinida...
This adaptable species thrives in open, often disturbed habitats, including grasslands, agricultural areas, urban and suburban environments, and along rivers and coasts, from sea level up to high elevations in the Andes.
Exclusively insectivorous, their diet consists primarily of small flying insects such as flies, beetles, wasps, and ants, which they capture with remarkable agility in mid-air.
Blue-and-white Swallows are highly diurnal, spending most of their active hours in continuous, acrobatic flight while foraging. At night, they often roost communally in large flocks on wires, in dense vegetation, or within protected cavities, exhibiting social behavior. Foraging involves agile ae...
The Blue-and-white Swallow boasts an extensive distribution, breeding from southern Central America (Costa Rica and Panama) southward throughout much of South America, reaching as far as Tierra del Fuego in the extreme south. While many populations are resident year-round, those in the southernmo...
