Common Kingfisher (Pyrenees' Biodiversity)

Common Kingfisher

Alcedo atthis

Summary ⁷

The Common Kingfisher (Alcedo atthis) also known as Eurasian Kingfisher, or River Kingfisher, is a small kingfisher with seven subspecies recognized within its wide distribution across Eurasia and North Africa. It is resident in much of its range, but migrates from areas where rivers freeze in winter.

Biology ⁸

The kingfisher feeds mainly on fish and invertebrates, which it catches by perching on a convenient branch or other structure overhanging the water, and plunging into the water when suitable prey comes within striking distance (2). If a suitable perch is not present, individuals may hover over the water whilst searching for prey (2). During the breeding season, pairs perform a display flight whilst calling. The nest consists of a tunnel in a riverbank or amongst the roots of a tree; both sexes help to excavate the tunnel, which terminates in a rounded chamber. In April or May 6-7 whitish eggs are laid on the bare earth, but after some time regurgitated fish bones form a lining to the nest chamber. Both parents incubate the eggs for 19-21 days. The young fledge after around 23-27 days, before this time they may eagerly approach the entrance of the tunnel when waiting to be fed (4).
