Sharp-shinned Hawks at Whitefish Point, MI: 5-13-17




Sharp-shinned Hawks









Female Sharp-shinned Hawks are about a third bigger and heavier than males.  This is a typical pattern for many hawks and owls, but otherwise rare in the bird world.













The size difference between the sexes influences the size of prey they can catch.  Nestlings feed first on small prey caught mainly by their fathers, switching as they grow to larger prey that their mother can bring.  






Before delivering prey to their mates or young, male Sharp-shinned Hawks typically remove and eat the head.






Checking the numbers, Sharpies are by far the most common raptor migrating over Whitefish Point.











Winter's here!
