Coastal Cisticola

Gray seabird shaped like a football. Breeding plumage shows white belly and thin white eyebrow and mustache. Distinctive stout orange bill with pale vertical protrusion at base. Nonbreeding birds have a plainer face and lack "horn" on bill; juveniles have gray bill. Longer bill than other auklets with a flatter head. Breeds on offshore islands; otherwise found at sea, usually alone. Dives underwater for fish.

Very small but stocky, quail-like bird of Patagonian steppe, sandy and stony plains in the Andes, coastal dunes, and deserts. Found in pairs or small groups; locally large flocks in nonbreeding season. Male has hooting song given from low mounds or fence posts, and sometimes during display flight. Flight is strong and fast; flushes with loud bleating chatters. Similar Gray-breasted Seedsnipe is larger, favors rockier Andean habitats, and has plain gray breast without diagnostic black Y pattern present on male Least Seedsnipes.

A spectacular enormous weaver endemic to São Tomé, with a robust barbet-like bill and a bulky head. Adult male has a black head and a chestnut collar that extends to the breast. Female is dull, with a buff wash on the breast. Juvenile is like the female, but browner on the upperparts. Fairly common in forest, forest edge, and plantations. Found in pairs and small groups. Song is a winding gurgle that ends with a wheezing fizzle: “drrt-drrt-drrt-grrzzzztztztztz.” Other weavers on São Tomé are much smaller, and their males lack chestnut coloration.
