The family Ardeidae comprises three subfamilies, viz., Tigriornithinae, Botaurinae and Ardeinae. The subfamily Ardeinae contains eleven extant genera, including Butorides.

The genus Butorides comprises green-backed herons and was first introduced by Edward Blyth (23 December 1810 – 27 December 1873), an English zoologist, in the year 1852.

The genus Butorides comprises three extant heron species, viz., B. virescens, B. striata and B. sundevalli.

The Butorides striata species is polytypic and comprises thirty-three subspecies. The B. striata species was first described by Carl Linnaeus (23 May 1707 – 10 January 1778), a Swedish botanist, physician and zoologist, in the year 1758.

Description

The striated heron is a small bird, measuring 35 to 45 cm in length and weighing 125 to 250 grams. The wingspan is 50 to 60 cm. The females are slightly smaller. The back and the wings are blue-grey in adult birds.

The underparts are white. It has a glossy greenish black cap and a short dark crest. A dark line extends from the bill to the lower edge of the eye. The bill is dark grey.

Habitat

The striated heron species prefer wooded water margins. They inhabit marshes, swamps, mangrove-lined shores and estuaries. They are observed on the margins of rivers, streams, ponds, lakes with thick marginal vegetation.

They also occur in river swamps, canals, artificial ponds, salt-flats, mudflats, tidal creeks and exposed coral reefs.

Feeding habits

The striated heron species feed on insects, crustaceans, frogs, tadpoles, molluscs, fish, lizards, small birds, rodents and vegetable matter.

Breeding

The Striated heron species construct a shallow nest with twigs hidden in trees and bushes. Specific breeding season is not observed. The nest may contain three to five eggs. Both the parents take turns to feed the hatchlings.

Distribution

There are thirty three subspecies of these herons, distributed all over the world. The nominate subspecies B. s. striata (Linnaeus, 1758) occurs in South America.

The subspecies B. s. chloriceps (Bonaparte, 1855) occurs in Indian Subcontinent and Sri Lanka. The subspecies B. s. spodiogaster Sharpe, 1894, occurs in Andamans, Nicobars islands of India and west Sumatra in Indonesia.

The subspecies B. s. virescens (Linnaeus, 1758) or green heron occurs in USA and Canada.

Movement Patterns

The striated heron species are mostly sedentary. The northern breeding populations migrate southwards for wintering. The populations in Africa may perform local movements relating to seasonal rainfall and feeding grounds.

Status and conservation

The striated heron species are threatened by human activities, habitat degradation and loss, pesticides and degradation of mangrove forests.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these striated heron species and has listed them as of "Least Concern".
