I often see this raptor at the lagoon, always solo.
The osprey (Pandion haliaetus), also called sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey. It’s large, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings.
The osprey is unusual in that it is a single living species that occurs nearly worldwide. Another oddity: osprey and owls are the only raptors whose outer toe is reversible, allowing them to grasp their prey with two toes in front and two behind. This is particularly helpful when they grab slippery fish.
