The American Kestrel is the smallest falcon in North America – about the size of a large thrush, such as the American Robin (Turdus migratorius), on average. Like all raptors, the American Kestrel is sexually dimorphic, although there is some overlap within the species. The female ranges in length from 9-11 in (23-28 cm) with a wingspan of 21-24 in (53-61 cm) and weighs an average of 4.2 oz (120 g). The length of the male varies between 8-10 in (20-25 cm) with a wingspan ranging from 20-22 in (51-56 cm) and weighing an average of 3.9 oz (111 g). These subtle differences are often difficult to discern in the field.
