Madagascar Green-Pigeon

Fairly common in Argentine Patagonia, but local and scarce in southern Chile. Favors semiopen habitats, from shrub-steppe to farmland with hedges and shrubby patches. Often perches atop bushes and on roadside wires and posts. Runs well on the ground, usually with tail cocked; at times can be rather elusive, skulking in bushes. Identified by bold pale eyebrow, buffy-gray underparts, white wingbars, and white tail corners; compare with White-banded Mockingbird, which has much more white in wings and tail.

Tiny antwren, heavily streaked with black and white above, solid yellow below. Females have a tawny-colored head. Note the two white wingbars. Inhabits the canopy and subcanopy of humid forest, including white sand forest; almost always associated with mixed-species flocks. The song is a monotonous repetition of “pew-pew” notes. The similar male of Pygmy Antwren has a white throat, while females are inseparable.

Huge white bird with a long elegant neck. North American “Whistling” Tundras have a mostly black bill, with a yellow spot near the eye; Eurasian “Bewick’s” have a more evenly divided black-and-yellow bill. Immatures dusky gray-brown with pink on bill. Easily confused with Whooper and Trumpeter Swans where their ranges overlap; see those species’ accounts. Breeds on ponds and tundra in far north. Winters in large flocks on fresh or saltwater. Forages in shallow, vegetated wetlands, reaching under the water for plants, and walks through corn stubble. Gives loud echoing bugles, often while in flight.
