• Western osprey feet are adapted for catching fish: they are long, with convex and curved claws, and the outer toe is freely turned backward. The outer toe is freely turned backward, allowing them to grasp slippery prey.
• Female western ospreys ask their mate for food, and if the male cannot feed her, they ask other males. This happens when the male cannot feed the female.
• Western osprey chicks cannot maintain normal body temperature for the first two weeks, and the female warms them almost constantly. Until four weeks, she also cares for them in case of excessively cold or hot weather.
• Western ospreys may be polygamous if nests are close to each other. The male can protect both nests, but the first receives more food, as he feeds there first.
• Western ospreys usually do not drink water — their needs are met by fresh fish. The percentage of successful dives into water varies from 24 to 74 depending on conditions.
• Migrating western ospreys behave unusually compared to other birds of prey, staying in their "winter apartments" year-round, instead of returning to their nesting areas in summer. One-year-old juveniles fly north only the following summer, when they have a chance to reproduce.
• The male western osprey brings 3–10 fish to the nest daily, each weighing 60–100 grams. At this time, he or the female cuts the fish into pieces and feeds the chicks.
