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 .
