White-crowned Hornbill

A large, slender lark with a long, thin decurved bill and long legs. Features can be variable, but generally the species has rufous upperparts, grayish coloration on the back of the neck, and a lightly streaked chest. As the similar-looking long-billed larks have separate ranges, location is a key factor in identification. This species strides purposefully through dry open shrubland, running quickly before pausing to dig in soil or pick at a shrub for invertebrate prey, seeds, or fruit. In a characteristic display the male flies low to the ground before flying directly up 10 to 15 meters, and then closing its wings and plummeting toward the ground while typically emitting a two-note “hit-seeeoooouuu” whistle, the second note descending. This call and similar ones can also be given from the ground. Most larks in the same range are smaller and more compact, with smaller bills and shorter legs.

Large, dark jay with vibrant blue plumage and a black head and bib. Frequents a variety of open habitats, including forest edges, gardens, and agricultural areas. Often particularly common in vegetation along rivers and other waterways. Distinguished from similar Purplish Jay by its brighter blue plumage and contrasting pale nape. Also listen for a high-pitched, piercing “jeer.”

A large oriole found primarily in secondary and submontane forests. Has a golden yellow body, a black head and throat, a red bill, and red eyes. The wings have uniform black primary flight feathers and some black edging on the secondary flight feathers. The tail is black with yellow feather tips. Easily confused with the co-occurring Western Black-headed Oriole, but note Black-winged Oriole’s solid black primary flight feathers and darker black tail. Voice is a varied series of whistles and liquid “tlee-o-yup!” calls.
