Melodious Warbler

Large, ubiquitous yellow-bellied flycatcher found throughout most of Middle and South America, though tends to be uncommon at the far northern end of its range in the U.S. A classic “telephone wire” bird along roadsides and in towns. Prefers open areas with some trees and water. Most abundant in lowlands and foothills, but ventures up to over 3,000m in some parts of range. Listen for sharp, high-pitched twitters. Nearly identical to Couch’s Kingbird, which overlaps from Texas to Belize; best separated by voice. Larger and longer-billed than Western and Cassin’s Kingbird; also note paler brownish tail. Also very similar to White-throated (longer, forked tail) and Snowy-throated (dark mask) Kingbirds in some parts of South America.

Attractive medium-sized sunbird of lowland forests, from coastal scrub forests to inland evergreen forests. Male is black with an iridescent pink-red throat, a red belly, and a glistening blue-green crown. Female is extensively yellowish with a pale vent and a thin dark line through the eye. Purple-throated Sunbird is essentially identical, but ranges do not overlap. Female Plain-throated Sunbird can be similar, but is straighter-billed, with a darker head, and a faint pale ring around the eye. Song, often given from an exposed perch, consists of squeaky rising whistles and chip notes.

This enormous heron stands 1.5 meters tall and has a robust, dagger-like bill. The immature has rustier upperwings than the adult. Its flight is ponderous and labored. Goliath Heron inhabits large rivers, marshes, estuaries, and mangroves, hunting for large fish and other animals, stabbing them with an open bill. It has a distinct, barking “kowoork” call that can be heard from up to 2 km away. Purple Heron has similar plumage, but Goliath Heron is twice the size, has a much larger bill, and has a rufous (not blackish) top of the head.
