ADULT

The sexes of the birds presented below were not determined by looking at the morphology of their plumage, but instead by studying the behaviour and establishing the relative size of the partners in a mated pair.

In addition to this, the male bird shown in photos taken in October 2013, which still has an at least partly immature plumage, is categorized here as an adult male, because it was found to be breeding with a female with adult plumage.

MALE
