Swinhoe's White-eye

Large brown owl with dark eyes and distinctive white semicircles on its face. Streaked below with distinctive pale white bars. Found mainly in open woodland, especially with Araucaria trees. The song is a deep and low “uh-uh-uh–prupruprrrr.”

Impressively large bird restricted to lowland rainforest in northern Colombia. It is critically endangered due to deforestation and hunting pressure. Male is black with a white belly and tail tip, shaggy crest, and blue bulges at the base of the bill. Female has a chestnut belly, a variable amount of white barring on body and crest, and a hint of blue at the base of the bill. Younger birds have less blue in the bill. Mostly terrestrial, but may ascend to low branches to sing or when threatened. It is only likely to be encountered in protected areas such as El Paujil Bird Reserve and Tayrona National Park.

Long-tailed little bird of dry forest and scrub in northwest Mexico. Found as singles, pairs, or family groups, usually foraging at low to middle levels. Breeding plumage male (March–August) has black cap, but other plumages very similar to Blue-gray Gnatcatcher, a common migrant throughout the range of Black-capped. These species best separated by call note: Black-capped has lower and rougher call than mew of Blue-gray. Also note Blue-gray often has a pinkish base to its smaller bill (gray on Black-capped), a more distinct white eyering (face a little more "open" on Black-capped), and a shorter, less strongly graduated tail.
