| Abstract: | Feathers in the nests of Cory's Shearwaters Calonectris diomedea are most evident during the incubation period mainly due to the formation of the brood-patch (Cachia Zammit & Borg 1986-87). However, feathers can be also found in dummy nests occupied at night by non-breeders, suggesting that even non-breeders may have a brood-patch. In incubating birds of both sexes, the brood-patch is quite evident when parting the ventral feathers. It consists of a relatively large bare area, roughly 9 cm in length and 5-6 cm in width, and is situated just above the cloacal aperture. The bare skin has a somewhat bluish coloration. |
