Here is a Bald Eagle with a freshly caught fish. That stare!
Every few years a story makes the rounds about a bald eagle carrying off a dog or trying to snatch someone’s cat. Biologists who study birds of prey and folks who live around eagles have seen plenty snatching and carrying – as well as swooping and swimming – and they offered insights into what eagles really can and cannot do.
Bald eagles are strong, aggressive birds but like everything that flies they are governed by aerodynamics. The wings of an eagle need to support the eight to 12-pound bird as well as whatever the bird is carrying, and best estimates put the lifting power of an eagle at four or five pounds. But it’s not quite that simple.
Lift is dependent not only on wing size, but on airspeed. The faster a bird (or plane) is flying, the greater the lift potential. An eagle that lands on the beach to grab a fish, and then takes off again, is limited to a smaller load than an eagle that swoops down at 20 or 30 miles an hour and snatches up a fish. That momentum and speed gives the bird the ability to carry more weight.
