The belted kingfisher (Megaceryle alcyon) is a large, conspicuous water kingfisher, the only member of that group commonly found in the northern United States and Canada. It is depicted on the 1986 series Canadian $5 note. All kingfishers were formerly placed in one family, Alcedinidae, but recent research suggests that this should be divided into three subfamilies.
The belted kingfisher is a stocky, medium-sized bird that measures between 28–35 cm (11–14 in) in length with a wingspan of between 48–58 cm (19–23 in). This kingfisher can weigh from 113 to 178 g (4.0 to 6.3 oz). The adult female averages slightly larger than the adult male.
This species has a large head with a shaggy crest. Its long, heavy bill is black with a grey base. These features are common in many kingfisher species. This kingfisher shows sexual dimorphism, with the female more brightly coloured than the male. Both sexes have a slate blue head, large white collar, a large blue band on the breast, and white underparts. The back and wings are slate blue with black feather tips with little white dots. The female features a rufous band across the upper belly that extends down the flanks. Juveniles of this species are similar to adults, but both sexes feature the rufous band on the upper belly. Juvenile males will have a rufous band that is somewhat mottled while the band on females will be much thinner than that on adult females.
Megaceryle is from the Ancient Greek megas, "great", and the existing genus Ceryle. The specific alcyon is Latin for "kingfisher".
The Megaceryle large green kingfishers were formerly placed in Ceryle with the pied kingfisher, but the latter is closer to the Chloroceryle American green kingfishers. The belted kingfisher's closest living relative is the ringed kingfisher (M. torquata), and these two in all probability originated from an African Megaceryle which colonized the Americas.
