Hartlaub's Gull
Chroicocephalus hartlaubii
A medium-sized, pale-gray-backed gull of coastal waters and human settlements. Breeding birds have dark eyes and a very faint chalky-gray hood, which non-breeding birds lack. This adaptable omnivore is the commonest gull of the Benguela Current, but its penchant for eating offal means it is expanding its range eastwards. The similar Gray-hooded Gull differs from Hartlaub’s Gull by being larger, having a yellowish-white eye, a longer redder bill, and a discrete grayish hood in breeding plumage. Immature Gray-hooded Gulls have a black terminal tail band which juvenile Hartlaub’s Gulls lack.
Grand Cayman Bullfinch
Melopyrrha taylori
Endemic to Grand Cayman. A small flocking species of brushy and wooded habitats. Note the very stout bill with strongly curved culmen, and the white slash along the front of the folded wing. Male is glossy black, female is smoky gray. No similar species occurs in its range. Song is a complex buzzy trill that drops in pitch and then rises steadily again. Calls include a hard chip and high buzzy “tzee” notes.
Marsh Warbler
Acrocephalus palustris
Medium-sized brown warbler, very similar to Eurasian Reed-Warbler. Best differentiated by the song, which is delightful, distinctive, loud, and full of mimicry of European and African birds. The call is a nasal, short "chek" or "tret." Longer wings than Eurasian Reed-Warbler, with distinctive pale tips to wing feathers. Bill rather short; legs pale and less warm-toned than Eurasian Reed-Warbler. Breeds in thick herbaceous vegetation in marshy areas and along ditches, not usually in the middle of wet reed beds. Can be found in drier habitats during the non-breeding season.
