The central tail-feathers are long-exserted, and spatulate by absence of webs along a part of the shaft - a mutilation effected, it is said, by the birds themselves; the bill is about as long as the head, gently curved; the nostrils are rounded, basal, exposed; the wings are short and rounded; the tarsi are scutellate anteriorly. It is greenish, with blue head." Elliot Coues, 1884
