Bird Island, Falkland Islands petrels and black-browed albatrosses. The total number of species recorded on Bird Island in November 1998 was 27, of which 25 bred or were probably breeding. Macaroni penguin, ruddy-headed goose, canary-winged finch, black-throated finch and Falkland steamer duck are present but their status is uncertain or populations are too small to qualify. The congregation of seabirds on this island exceeds 10,000 breeding pairs, making the site classifiable under the A4iii criterion. Bird Island is one of the most important breeding sites for the striated caracara and it is considered that the population here is at least as dense as on

This is particularly true in the male kestrels.
