About Conirostrum bicolor (Vieillot, 1809)
Conirostrum bicolor, commonly known as the bicolored conebill, measures 11.4 cm in length and weighs 11 g. Adult bicolored conebills have grey-blue upperparts, buff-tinged grey underparts, red eyes, pink legs, and a sharp, pointed bill. Their primary flight feathers are bluish with brown edgings. Males and females are similar in appearance, though females may be slightly duller in color. Immature birds have greenish upperparts and pale yellow underparts, and can sometimes breed while still retaining their immature plumage. This species inhabits coastal mangrove swamps and adjacent neighboring woodlands. It builds a small feather-lined cup nest in mangrove trees, and typically lays a clutch of two buff eggs marked with brown blotches. Nests of the bicolored conebill are often parasitized by shiny cowbirds.
