Island Whistler

Small heron, usually found in reed beds, expansive marshes, and rice fields; can occasionally be found in parks with sheltered areas, particularly lotus ponds and shaded pools. Generally uncommon throughout its range; never in the high densities of Yellow Bittern. Male is smartly attired, with a black cap, brown back, and a white neck and breast with a dark line extending down from the throat. Female is darker, with fine white spotting on the back and pale brown streaks on the throat. Compare with Cinnamon Bittern. Males give a gruff “roof, roof, roof” on the breeding grounds.

A dull and poorly marked prinia with a strong bill and a long, graduated tail. Light brown above with faint dark streaking. Pale below, sometimes with some dark smudging along the sides of the breast. In some areas, breeding males become darker on the face and the bill becomes black. Found at low and moderate elevations in open dry forest, shrubby grasslands, and forest or agricultural edges. Can be retiring and difficult to see in dense vegetation. Sings two different song types: a dry rolling trill and a repeated two-syllabled “tulip.” Separated from most other prinias by its plainness and lack of contrasting head markings. Most similar to Himalayan Prinia, but there is little or no overlap in range, and Burmese Prinia is distinguished by having less streaking overall, especially along the sides of the breast.

Slender, long-tailed, chickenlike bird that is often seen in small groups. Grayish-brown overall with a warmer chestnut head. At close range note the bare red throat patch and pinkish legs. Found in second-growth woodlands, river edges, and disturbed habitats including farms and villages. Occurs in lowlands of northern South America, north of the Amazon river. Somewhat similar to Spix’s and Marail Guans, but Variable Chachalaca is much smaller and is unlikely to be in canopy of tall forest. Usually quiet, but groups call loudly to each other early in the morning; unmistakable call can be heard for more than a kilometer.
