About the Green Heron

The green heron (Butorides virescens) is a small heron of North and Central America. Butorides is from Middle English butor "bittern" and Ancient Greek -oides, "resembling", and virescens is Latin for "greenish". It was long considered conspecific with its sister species the striated heron (Butorides striata); when treated together, they were called "green-backed heron".

The green heron is a relatively small heron; 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, an iridescent greenish back and wings that are gray-black grading into green or blue, a chestnut neck with a pair or more of white lines down the front, gray underparts and short yellow legs. The bill is dark with a long, sharp point. Female adults tend to be smaller than males, and have duller and lighter plumage, particularly in the breeding season. Juveniles are duller, with the head sides, neck and underparts streaked brown and white, tan-splotched back and wing coverts, and greenish-yellow legs and bill. Hatchlings are covered in down feathers, light gray above, and white on the belly.
