The least bittern arrives on its breeding grounds about a month after the American bittern and leaves one or two months earlier. John James Audubon noted that a young captive least bittern was able to walk with ease between two books standing 4 cm (1.6 in) apart. When dead, the bird's body measured 5.7 cm (2.2 in) across, indicating that it ...

The least bittern (Ixobrychus exilis) and the stripe-backed bittern (Ixobrychus involucris) were nested with members of the genus Botaurus. Hruska and collaborators resurrected the genus Calherodius Peters , 1931 to contain two night herons (the white-backed night heron and the white-eared night heron ) that were previously placed in Gorsachius .
The green heron is relatively small; adult body length is about 44 cm (17 in). The neck is often pulled in tight against the body. Adults have a glossy, greenish-black cap, a greenish back and wings that are grey-black grading into green or blue, a chestnut neck with a white line down the front, grey underparts and short yellow legs.
The Butorides herons were formerly considered one species, but are now normally split as above, with the green heron breeding in eastern North America, Central America, the West Indies and the Pacific coast of Canada and the United States, and the striated heron in South America, and the Old World tropics and warm temperate regions from west Africa to Japan.
[2] [3] The name Botaurus is Medieval Latin for a bittern. The word combines Latin bos meaning "oxen" (compare butire "to boom") and taurus meaning "bull".
