Yellow-bellied Tit

A slim nightjar with a slightly elongated central tail. Both sexes have a large pale mark in the outer wing and along the sides of the tail, white in males and buff in females. Found mainly in dry savanna, but also in other open habitats. Similar to Long-tailed Nightjar, but usually shorter-tailed, and plumage is grayer in the area where their ranges overlap. Call is a slow mechanical trill, lower-pitched than similar calls of other nightjars. Also gives a “pwit” call, often in flight.

A small, very dark brown shorebird with a very short thin bill and a distinct white eyebrow. Upperparts spotted with buff, underside spotted or barred with brown. Legs yellow or grayish. In flight, looks very dark with very rounded wings. Prefers coastal shoreline and bare gravel of tiny atolls. Combination of odd proportions, very short thin bill, and white eyebrow should make this species unmistakable. Most common call is a nasal “kek,” but when excited gives a loud piping whistle and a series of rising and falling trills.

Handsome warbler found only at higher elevations in Colombia’s Santa Marta Mountains. The combination of yellow body and ornately patterned black and white head is unique within its limited range. Hides in dense tangles in cloud forest understory, especially in bamboo patches, and can be hard to see well. Pairs sing duets where one bird gives a rising and falling series of squeaks, and its mate adds a steady series of tic notes. Small numbers can usually be found along the road in the upper reaches of El Dorado Nature Reserve.
