Common Cactus-Finch
Geospiza scandens
This cactus-loving Galápagos finch has an especially distinctive bill, which is long, deep at the base, and often appears droopy. Bill is black on breeding male and dull orange on female and nonbreeding male. Male’s plumage is sooty-black; female is dark brown with paler underparts that are blotched with gray. Most prevalent in arid coastal areas, where it is often seen feeding on prickly pear flowers. Found on most islands, but absent from Española, Genovesa, Santiago, and Fernandina.

Madagascar Serpent-Eagle
Eutriorchis astur
Very rare and enigmatic large raptor that is endemic to Madagascar. Occurs very locally in pristine eastern rainforest, where it hunts inside of the forest, never soaring. Call is a series of low “how” notes, sometimes delivered in slow series and sometimes more quickly and emphatically. Very similar to Henst’s Goshawk. Subtle differences include slightly larger size, denser barring on the chest, thinner black bands on the tail, and dark barring on the back.
Black-and-chestnut Warbling Finch
Poospiza whitii
Gray and rich rufous tanager of open scrub in the Andes from central Bolivia to NW Argentina. From Cinnamon Warbling-Finch by white supercilium and richer coloration. From Bolivian Warbling-Finch by rufous throat and wider rufous breast band.
Fiji Petrel
Pseudobulweria macgillivrayi
A relatively small, entirely dark petrel, appearing chocolate-brown or black, with a distinctive short-necked and cigar-shaped silhouette due to its tapering tail. Lacks the white underside of the otherwise similar Beck’s Petrel, and is significantly smaller than and lacks the white belly of Tahiti Petrel. Similar to Bulwer’s Petrel, but lacks the pale bars found in the upperwing of that species, appears shorter-necked, and does not hold its head high in flight. Overall flight style of Fiji Petrel is more acrobatic than that of Bulwer’s Petrel.
