Female Sharp-shinned Hawks are about a third bigger and heavier than males. This is common for hawks and owls, but otherwise uncommon amongst birds. The difference in size between the sexes reflects in the size of their prey. Nestlings feed first on small prey captured by the father, before moving on to the larger prey caught by the mother. One Sharp-shinned Hawk was found in Central Park in this year's Bird Count.
