Blue-And-White Swallow
Notiochelidon cyanoleuca
About This Species
A graceful aerial forager, it hawks flying insects low over open ground, water and grassland, often seen perched on wires or nesting under eaves and bridges in loose colonies. Look for its steely blue-black upperparts and white underparts as it swoops in fast, agile flight, most active at dawn and dusk when insect activity peaks, and most visible near water or open pasture through the breeding season.
Ethical Viewing Guidelines
- Keep a respectful distance of several metres from nest sites under eaves, bridges or culverts, since repeated disturbance can cause adults to desert eggs or nestlings.
- Protection for nesting swallows varies across its range in the Americas, so check local wildlife regulations rather than assuming a single rule applies everywhere.
- Avoid blocking nest entrances or lingering directly beneath active nests.
