Riberia de Ponte. One of the famous
Corvo eastern valleys. These sub-tropical valleys are the best location in the Western
Palearctic for
Nearctic landbird vagrants. This particular valley has hosted Black-
throated Blue Warbler and Ovenbird.
In addition to these valleys there are other areas of habitat on the island- a lake, an airstrip, low lying dry stone walled fields, upland fields, cliffs and the ocean. This
mosaic of habitats and the location of
Corvo in the mid-Atlantic contributes to
Corvo reigning supreme as the ultimate vagrant trap in the Western
Palearctic.
With a vegetation type which is typically
Macronesian/Mediterranean and residents birds made up
Palearctic species (Blackbird, Blackcap,Grey Wagtail, Canary, Starling, House Sparrow, Goldfinch, Chaffinch, Yellow-legged Gull, Woodcock, Snipe and
Wheatear) the island is perfectly European- Europe's western most outpost.
Corvo on the eastern flank. This area is characterised by steep farmed slopes which are cut by wooded valleys. These wooded valleys are where the real hidden treasures lie. Vagrants include White-eyed Vireo, Philadelphia Vireo, Hooded Warbler, Northern
Parula, Black-
throated Blue Warblers, Black-
throated Green Warbler, Yellow-bellied Sapsucker, Hermit Thrush, Grey-cheeked Thrush,
Blackpoll and Yellow-rumped Warbler.
Corvo Island, the western flank. The
precipitous wind swept cliffs are least productive for vagrants but provide possible nesting areas for petrels and
shearwaters. Closer to sea level there are colonies of breeding Roseate and Common Terns .
Corvo Island. Southern flank showing the village and surrounding fields. Vagrants recorded in this area include White-crowned Sparrow, Summer and Scarlet Tanager,
Yellowthroat, Red-eyed Vireo, Yellow-rumped Warbler, Bobolink, Yellow-billed Cuckoo, Mourning Dove, Chimney Swift, Arctic
Redpoll, Killdeer,
Hudsonian Whimbrel and other waders and gulls on the airfield.

American waders and ducks.
