Rufous-browed Chat-Tyrant

A tiny bird that skulks in the dense undergrowth of evergreen forests, particularly around running water. Brown above with a large white throat patch and belly. Similar to Tawny-breasted and Gray-bellied Wren-Babblers, but the Long-tailed Wren-Babbler has a longer tail and distinct white streaks along the flanks. The song is a relatively short warble of 3-5 loud, melodic notes.

Small short-tailed antbird found around still and slow-moving water in humid forest. Medium gray; tail black, with a broad white terminal band. Males have a black throat; females are lighter underneath. Forages low at the water’s edge and in vegetation overhanging the water around oxbow lakes and streams. The male’s song is an ascending series of whistles accelerating into a harsh descending series; it can be attention-grabbing with its grating snarling ending.

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.
