ニシツバメチドリ

The Collared Pratincole, known scientifically as <em>Glareola pratincola</em>, is a wading bird belonging to the family Glareolidae. <em>Glareola pratincola</em> is characterised by its distinctive pale throat patch bordered by a dark necklace or collar, giving the species its common name. The species is known for its swallow-like flight silhouette, with long, pointed wings and a forked tail, which it uses to pursue flying insects in aerial sorties over open habitats. It is reported to occur in Belgium, Denmark, Norway, Sweden, and Ukraine. Collared Pratincoles typically breed in open, dry habitats such as grasslands, mudflats, and steppe environments near water, and are often highly gregarious during the breeding season. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature.
