West Mexican Euphonia

A small, sharp-billed warbler-like bird. Note the yellow patches on the throat and undertail and the bold white spectacles around the eye. Common on the island of Anjouan in the Comoros in habitats with woody vegetation, including remnant forest patches, plantations, woodland, scrub, and gardens. Usually found in hyperactive flocks. In its small range, easily identified by the white spectacles. The most common calls are a high-pitched, rising rattle and a descending “chew” note, which is also the main component of the quiet, chatty song. 

Small warbler found in cloud forest in western Colombia and northwestern Ecuador. Field marks include bright yellow underparts a well as dark stripes through face and on sides of crown. Orange central crown stripe may not be evident in the field. Similar to Three-striped Warbler, but yellower, has thinner crown stripes, and lacks crescent below eye. Pairs or small groups forage actively in lower to middle levels in the forest, often with mixed species flocks. Song is a rising and accelerating buzzy trill. Formerly called Golden-bellied Warbler.

Large seabird, very similar to Masked Booby. Long and pointy on all ends: wings, tail, and bill. Adults mostly gleaming white with black flight feathers and face; note pinkish-orange (not yellow) bill to help separate from adult Masked. Young birds darker overall with brown head contrasting with white belly and dirty brown markings on underwings; very similar to young Masked or even adult Brown Booby. Found in the Pacific Ocean from Mexico to Peru where it feeds on fish; breeds on rocky islands, especially the Galapagos.
