Common Kingfisher

Alcedo atthis

Beautiful little blue-and-orange bird with a long, pointed bill. Often rather shy and inconspicuous despite bright plumage. Found along rivers, streams, lakes, and ponds—almost any fresh or brackish habitat with small fish. Often perches quietly in trees over water; most often seen in very fast low flight as a turquoise flash over the water, usually flying away. Easily detected once its high, shrill whistled call is learned, even if the bird itself is hidden. The only small blue kingfisher over much of its range.

Identification

This species has the typical short-tailed, dumpy-bodied, large-headed, and long-billed kingfisher 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.The flight of the kingfisher is fast, direct and usually low over water. The short, rounded wings whirr rapidly, and a bird flying away shows an electric-blue "flash" down its back.In North Africa, Europe and Asia north of the Himalayas, this is the only small blue kingfisher. In south and southeast Asia, it can be confused with six other small blue-and-rufous kingfishers, but the rufous ear patches distinguish it from all but juvenile blue-eared kingfishers; details of the head pattern may be necessary to differentiate the two species where both occur.The common kingfisher has no song. The flight call is a short, sharp whistle chee repeated two or three times. Anxious birds emit a harsh, shrit-it-it and nestlings call for food with a churring noise.There are seven subspecies differing in the hue of the upperparts and the intensity of the rufous colour of the underparts; size varies across the subspecies by up to 10%. The races resident south of the Wallace Line have the bluest upperparts and partly blue ear-patches.

Taxonomy

The common kingfisher was first described by Carl Linnaeus in the 10th edition of his Systema Naturae in 1758 as Gracula atthis. The modern binomial name derives from the Latin alcedo, 'kingfisher' (from Greek ἀλκυών, halcyon), and Atthis, a beautiful young woman of Lesbos, and favourite of Sappho.The genus Alcedo comprises seven small kingfishers that all eat fish as part of their diet. The common kingfisher's closest relative is the cerulean kingfisher that has white underparts and is found in parts of Indonesia.

Range and habitat

The common kingfisher is widely distributed over Europe, Asia, and North Africa, mainly south of 60°N. It is a common breeding species over much of its vast Eurasian range, but in North Africa it is mainly a winter visitor, although it is a scarce breeding resident in coastal Morocco and Tunisia. In temperate regions, this kingfisher inhabits clear, slow-flowing streams and rivers, and lakes with well-vegetated banks. It frequents scrubs and bushes with overhanging branches close to shallow open water in which it hunts. In winter it is more coastal, often feeding in estuaries or harbours and along rocky seashores. Tropical populations are found by slow-flowing rivers, in mangrove creeks and in swamps.Common kingfishers are important members of ecosystems and good indicators of freshwater community health. The highest densities of breeding birds are found in habitats with clear water, which permits optimal prey visibility, and trees or shrubs on the banks. These habitats have also the highest quality of water, so the presence of this bird confirms the standard of the water. Measures to improve water flow can disrupt this habitat, and in particular, the replacement of natural banks by artificial confinement greatly reduces the populations of fish, amphibians and aquatic reptiles, and waterside birds are lost. It can tolerate a certain degree of urbanisation, provided the water remains clean.This species is resident in areas where the climate is mild year-round, but must migrate after breeding from regions with prolonged freezing conditions in winter. Most birds winter within the southern parts of the breeding range, but smaller numbers cross the Mediterranean into Africa or travel over the mountains of Malaysia into Southeast Asia. Kingfishers migrate mainly at night, and some Siberian breeders must travel at least 3,000 km (1,900 mi) between the breeding sites and the wintering areas.

Other Birds

Black-headed Shrike-Babbler

Pteruthius rufiventer

Large-headed songbird with confusingly dissimilar male and female plumages. Male has an orange back, white throat, orangish belly, and a black head and wings. Female is green-winged and gray-headed, with a darker crown and triangular patch behind the ear. She shares the male’s warm-colored belly, but hers is more salmon-pink than orange-yellow. The species inhabits mature foothill forests, where it may often be seen with mixed-species foraging flocks.

Rusty-crowned Tit-Spinetail

Leptasthenura pileata

Attractive, long-tailed bird found in the high Andes of Peru. Plumage is brown overall with a chestnut crown, speckled throat, and streaked belly. Plumage varies geographically, and birds in southern Peru are much darker below with bolder streaking. Inhabits scrub and woodland with short trees. Vocalizations have a metallic quality; they include a high-pitched trill and a series of sharp chips.

Chinese Rubythroat

Calliope tschebaiewi

Handsome male is gray above with a bright red throat, black chest, and white belly. Also note white eyebrows and “moustache” stripe, as well as white panels and edges on a black tail. Female is duller, cold gray-brown above with a white belly and throat. Extremely similar to Himalayan Rubythroat: note gray flecking on white flanks of male and white “moustache” (striking in males, pale and sometimes unnoticeable in females). Breeds in alpine and subalpine open areas with scattered scrub and boulders; preferred habitat averages higher and more open than Himalayan. Winters in lowland scrub. Song is a series of loud rich warbles, which average shorter and less varied than those of Himalayan Rubythroat.
