25-8-2015 VILLALONGA RESERVOIR, VALENCIA - COMMON KINGFISHER (FEMALE) (Alcedo atthis)

The Common kingfisher (Alcedo atthis) is a small kingfisher widely distributed across Eurasia and North Africa. It is amongst the most colorful birds but despite its extraordinary colors, sometimes the Common kingfisher is difficult to see when it is in a dappled shade, and its colors are also not very obvious in flight. Furthermore, due to its shy nature, the Common kingfisher often remains hidden from a human's eye.

The Common kingfisher has the typical short-tailed, dumpy-bodied, large-headed, and long-billed shape. The adult male of the western European subspecies, A. a. ispida has green-blue upperparts with pale azure-blue back and rump, a rufous patch by the bill base, and a rufous ear patch. It has a green-blue neck stripe, white neck blaze and throat, rufous underparts, and a black bill with some red at the base. The legs and feet are bright red. The female is identical in appearance to the male except that her lower mandible is orange-red with a black tip. The juvenile is similar to the adult but with duller and greener upperparts and paler underparts. Its bill is black, and the legs are also initially black. Feathers are moulted gradually between July and November with the main flight feathers taking 90-100 days to moult and regrow. Some that moult late may suspend their moult during cold winter weather.

Despite its brightly-coloured plumage, the Kingfisher can be a challenging bird to spot when perched on a waterside branch. More often than not you will be first alerted to its presence by its piping call.

Widely distributed on lowland rivers and still-waters, the Kingfisher is a species whose fortunes have waxed and waned. Numbers are impacted by severe winter weather, and this may be the main driver of change, but changing water quality and availability of favoured prey may also play a role.

Kingfishers may move away from their breeding territories during the winter months, including to more coastal sites, in order to reduce the impacts of poor winter weather on fishing opportunities.
