These are relatively common along the western coast of South America. I've seen them very close on the Galapagos and they have a vivid yellow eye with a jet black pupil and bright red eye ring; it looks unreal against the black of their feathers.

Ooops! right again vpm001. In Equador they called them black oystercatchers and I just didn't think to check the scientific name - and me such a supporter of scientific names over common ones on iSpot; I should listen to my own advice! Needless to say my comments above should be transposed to Blackish oystercatcher (Haematopus ater).
