The Osprey (Pandion haliaetus), is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings.
It is brown on the upperparts and predominantly grayish on the head and under parts, with a black eye patch and wings.
It is sometimes known as the sea hawk or fish hawk and its diet consists almost exclusively of fish.
You usually do not see the pair in the nest at the same time. Having observed both guarding the nest at different times, I can tell that this one is the female.
The sexes appear fairly similar, but the adult male can be distinguished from the female by its slimmer body and narrower wings. Also the breast band of the male is also weaker than that of the female, or is non-existent, and the under wing coverts of the male are more uniformly pale. The male, of this pair, is noticeably smaller.
It's pretty straightforward to determine the sex in a breeding pair seen together, but harder with individual birds.
