Javan Whistling-Thrush

A bulky, mostly pale white-eye with a whitish head and belly and gray-brown wings and tail. Small to large groups join mixed flocks in forest and plantations throughout Príncipe. Calls include a high-pitched chittering, uttered as a group, and a repeated “tsit-tit-cher-it-it” song. Principe Speirops may join the same flocks as Principe White-eye, which is slightly smaller and much darker, lacking the distinctive white head and underparts. 

Small, perky antbird. Males are slate-gray with an often-concealed white patch on their backs and narrow white tail tips (lacking in the western subspecies). Females have an olive-gray back and are tawny-buff below. Found at the forest edge and in second growth, where it forages in pairs in the understory and is not normally associated with mixed-species flocks or army-ant swarms. The similar Dusky Antbird has a white tipped tail in the area of overlap with the western subspecies. The song is easy to recognize, a sharp, high, positively joyful “puh-wéedi-wéedi-wéedi-wéedi.”

Dark brown nightjar of humid forests. Smooth reddish brown overall with small black spots, a clean white throat band, and white tail corners. In flight, appears dark brown overall with white tail corners but no white wing patches. Look for it in mature rainforest, with or without dense understory. Song is a single quavering, reverberating note, “PEEur,” like plucking a taut string.
