Sulphury Flycatcher

A nocturnal inhabitant of open arid woodlands and thornscrub. Perches on ground from which it makes floppy and erratic flight upon its long wings in pursuit of insects. During the day it nestles in shaded leaf litter, wherein its cryptic coloration hides it well. Both the Hispaniolan Nightjar and Chuck-wills-widow are considerably larger, darker, and lack the Least Pauraque’s white terminal tail band. Calls include a low scratchy “wuck-wuck-wuck-wuck,” a low-pitched rising and trilled “tooooooeeeeeee,” and a similarly low-pitched trilled “oo-weee-oo,” with emphasis on middle syllable. The calls of the Hispaniolan Nightjar is a lower pitched “toooooeeeeeo.”

A pale powder-blue-and-white seabird with a faint grayish dark “M” across the upperwings. Note the dark blue “thumb mark” collar, the blue eye-stripe, the white eyebrow, the white throat, and the grayish cap. Restricted to two known breeding islands, Saint Paul in the South Indian Ocean, and Gough in the South Atlantic. Almost identical to Antarctic Prion, but bulkier and more heavy-chested, with a slightly wider bill. All but inseparable from Salvin’s Prion, with which it shares the breeding island of Gough, and with which it was once considered one species; MacGillivray’s is incrementally broader-billed, but birds seen at sea may not be identifiable.

This large trogon is the only one in its range with a pale eye. Male is green and red with no white band separating the chest from the belly; female similar but gray-brown instead of green. Otherwise, a typical trogon with upright posture, squared-off tail, and stout yellow bill. Sits still at middle levels in trees, slowly turning head searching for prey.
