释义 | kingfisher bird ![]() These vocal, colourful birds are renowned for their dramatic hunting techniques. Typically the bird sits still, watching for movement from a favourite perch. Having sighted its quarry, it plunges into the water and catches the fish usually no deeper than 25 cm (10 inches) below the surface in its dagger-shaped bill. With a swift downstroke of the wings, it bobs to the surface. It then takes the prey back to the perch and stuns the fish by beating it against the perch before swallowing it. Many species also eat crustaceans (crustacean), amphibians (amphibian), and reptiles (reptile). The typical kingfishers (subfamily Alcedininae) are river dwellers, like the belted kingfisher (Megaceryle alcyon), the only widespread North American species. This handsome crested bird flies off over the water when disturbed, uttering a loud, rattling call. It is about 30 cm (12 inches) long and is bluish gray above and across the breast and white below. Only the females sport the brownish red band or “belt” across the lower breast. In its courtship ritual, the male offers fish to the female as she perches. After copulation, the pair circle high overhead and chase each other while crying shrilly. ![]() |
