Brown-headed Gull

Large, boldly patterned, and often noisy ibis. Common and conspicuous in cooler and wetter regions of southern Chile and Argentina; uncommon and more local in northern areas. No similar species in range. Favors open country, especially wet grasslands, but also ranges to open forest and beaches. Nests colonially in trees and on cliffs, including in towns and even cities. Soars easily on broad wings, sometimes high with kettles of vultures. Loud trumpeting cries carry long distances.

Tiny finch of tropical lowlands and foothills, especially in drier areas. Endemic to West Mexico, where it is found in open woodland, forest edge, and clearings with trees. Usually in pairs, sometimes small groups, often feeding at mistletoe. Male has black head and throat with yellow forehead patch and white undertail coverts; female rather drab yellowish below and olive above. The only other euphonia in West Mexico is Elegant Euphonia, which has a distinctive blue crown and nape.

A medium-sized yellowish-olive bird with a long tail that is often flipped up and down. Endemic to the remote island of Rodrigues. Found in secondary forest, scrub, and plantations. Feeds both in the undergrowth and up into the canopy. The cheerful song is a quick series of several musical warbling notes in an up-and-down pattern. The calls include “chek” notes and rattling scolds. There are no other warblers or otherwise similar species on Rodrigues, so identification is simple.
