Little Sunangel

Breeding males have obvious white blaze on forehead and broad green slash behind eye. Females are plainer brown with rusty sides. Females are very difficult to distinguish from female Eurasian Wigeon; note colder grayish-brown head on American that contrasts with warmer orangey sides. Also look for brighter white, not gray, underwings in flight, but this can be difficult to judge, especially at a distance. Widespread and common in North America, occasionally wintering as far south as northern South America. Typically in flocks on lakes and wetlands, often grazing in nearby fields. Regular vagrant to Europe.

Elusive falcon of lowland and foothill rainforest east of the Andes. Note black upperparts, white underparts, white hindcollar, and dull yellow face. Female may show white spots on wings. Immature is barred underneath with brownish nape. Adult is very similar to pale morph Collared Forest-Falcon but slightly smaller; ID is best confirmed by voice. Typical song of Buckley’s is “kawah, koh”, sometimes followed by a lower “koh” note. Usually stays inside forest and is infrequently seen.

A small, pallid, long-winged leaf warbler. Separable from the closely related Western Bonelli's Warbler by range and vocalizations. Similar to other leaf warblers such as Common Chiffchaff and Willow Warbler, but note present species’ plainer facial pattern, prominent yellowish-green wing panel and outer tail feathers, and very white underparts. Song is a short, ringing trill. Call is a distinctive sharp “tzip.” Flits around in bushes and trees searching for tiny invertebrates; often hovers while feeding. Breeds in dense Mediterranean scrub and forests. During non-breeding season, found in various vegetated habitats including desert acacia wadis, open woodlands, and scrub.
