The greater crested or swift tern is larger than the lesser crested tern with a paler, slightly decurved bill. Both are shown in some of these photos. The top photo was taken at Fish Eagle Point (8-17), courtesy of Per Holmen. The next two photos were taken on Maziwe island (1-13), courtesy of Paul Oliver. All of the other photos were also taken at Pemba Abwe and on Maziwe island. |
