An osprey — also called sea hawk, river hawk, and fish hawk — is a fish-eating bird of prey with a cosmopolitan range. It 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 greyish on the head and underparts. My illustration is a blue-ish grey with a reddish stripped tail.
