28-3-2017 TARCOLES RIVER COSTA RICA - AMAZON KINGFISHER (Chloroceryle amazona)

                             

The Amazon kingfisher (Chloroceryle amazona) is a species of "water kingfisher" in subfamily Cerylinae of family Alcedinidae. It is found in the lowlands of the American tropics from southern Mexico south through Central America to northern Argentina.

The Amazon kingfisher resembles the green kingfisher which shares its range, but it is much larger than its relative, and three to four times as heavy. It is 30 cm (12 in) in length and weighs 98–140 g (3.5–4.9 oz). It has the typical kingfisher shape, with a short tail and long bill. It is oily green above, with a shaggy crest and a white collar around the neck. It lacks the white markings on the wings shown by green kingfisher.

Males have white underparts apart from a broad chestnut breast band and some green streaks on the flanks. Females have white underparts with green patches on the side of the chest and green flank streaks. Young birds resemble the adult female, but have white spots on the wings. These birds often give a harsh teck call. The rarely heard song, given from a tree top, is a whistled see see see see.

This large kingfisher breeds by streams. The unlined nest is in a horizontal tunnel made in a river bank, and up to 1.6 m (5.2 ft) long and 10 cm (3.9 in) wide. The female lays three, sometimes four, white eggs.

Amazon kingfishers are often seen perched on a branch or rock close to water before plunging in head first after their fish prey. They also feed on insects and amphibians. They are the most likely American green kingfisher to be seen on large rivers.
