Rufous-necked Sparrowhawk

Widespread, rather large but “average” coot of lakes, marshes, and river mouths; mainly in Andes and adjacent Pacific coastal lowlands. Despite the name, its plumage is no more slate-colored than other coots. Adult comes in three types: most Andean birds have a dark red forehead shield and yellowish bill; elsewhere, rounded forehead shield can be white or pale yellow with a whitish bill. Legs greenish, appreciably shorter than legs of Giant Coot, which occurs alongside Slate-colored at some lakes. Juvenile has a variably grizzled whitish face and throat.

Large, stocky brown bird. Largely arboreal, but often seems too large or clumsy for its tree-dwelling habits. Calls loudly when flushing from a tree and makes crashing noises as it lands roughly in another tree. Found around forest edges and young forest as well as in more mature forests. Typically found singly or in pairs, occasionally in larger groups. Larger and darker than chachalacas with more prominent red skin on throat.

Very striking cormorant readily identified by white neck. Locally common black-and-white cormorant of colder coastal waters. Often seen perched on inshore rocks and jetties, sometimes with Magellanic Cormorant. Nests colonially on low islands (rarely in lakes inland from coast) and jetties. Plumage varies regionally, with some birds black-faced and others white-faced; the two types breed together locally in the Strait of Magellan. Immature resembles adult but plumage duller overall, brownish above.
