Yap Cicadabird

Cryptic heron of freshwater marshes in tropical lowlands. Usually in areas with tall grasses or rushes, rarely in open situations. When alarmed, often freezes motionless with neck upstretched. The neck is finely barred horizontally, but the body plumage is vertically streaked (not horizontally barred and banded, as on immature tiger-herons). Compare with immature night-herons, which have streaked, not finely barred necks.

Small, olive-green tinkerbird. There are yellow patches on the wing and rump and a white slash on the face. Found in and around montane forest at middle and high elevations. Most often detected by voice: a chirpy series of “tek” notes, which varies from a fairly slow series of 3-4 notes to a long series of very fast notes. Very similar to Green Tinkerbird, but only overlaps slightly in range, and separated by the white facial mark.

Short-tailed antbird of forest understory. Both sexes have black face. Males are gray with white wingbars; females are brown above, buffy below, with cream wingbars and a white or buffy throat. Forages singly or in pairs low in the undergrowth of mature forest. Usually inhabits more mature forest than similar White-browed Antbird, but there is some overlap. Note differences in facial pattern; males lack the white eyebrow and females lack the orange eyebrow seen on White-browed Antbirds. Female Black-faced Antbirds also have browner underparts than White-browed. Listen for an even-paced series of 5–7 whistles that is slightly higher in the middle. In the southern part of its range, these whistles are pure-toned; in the north, they are harsher.
