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).[6] 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.
