Juvenile Cooper's Hawk (Astur cooperii) at San Jose, California - August 2022
Featured Subspecies: N/AWeight: 215-700g / Length: 36-51cm / Wingspan: 71cm
NO UK STATUS / IUCN Red List: Least Concern
A highly sex dimorphic species of hawk where the difference is so pronounced that there is only a comparatively minor overlap of proportions and weights between male and female birds, with the female being the larger. They feed almost exclusively on vertebrate prey, and unlike Sharp-shinned are much more likely to take terrestrial mammals. They are somewhat infamous as a species which can cause identification problems in the field if clear views aren't had compared to the smaller sharp-shinned.
