Cattle Tyrant

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.

Fairly small brown bird, shows a thin buffy line behind the eye and thin buffy streaking all over head, back, and underparts. Throat is cleaner buffy. In many parts of range, this is the only foliage-gleaner with such obvious streaking. In some regions, beware treehunters, which are larger and longer-billed. Found in montane forests, where it usually follows mixed flocks through the forest understory. Stays in the lower levels, probing around tangles and leaf clusters. Listen for series of forced nasal notes.

A fairly small, slim, long-tailed hornbill. Note the red bill, the pink or red bare facial skin, and the heavily spotted back. The eye is dark in most of the range, but birds in some parts of East Africa show a pale eye. White patches on the wing and outer tail are conspicuous in flight. Found in savanna and thornscrub. Similar to Western and Tanzanian Red-billed Hornbills, but separated from both by the pale rather than black bare skin around the eye. Call is a series of clucks that starts with single notes, then becomes louder and more emphatic, with doubled notes.
