BIRD OF THE WEEK: February 22, 2019SCIENTIFIC NAME:Parabuteo unicinctus POPULATION: 55 million TREND: Stable HABITAT: Resident in desert scrub, lowland savanna, or marshy open country.
Harris’s Hawk is found from the southwestern United States through Mexico and in appropriate habitats as far south as Argentina. One of the species’ interesting behaviors is called “back stacking,” when up to four Harris’s Hawks stand on top of each other while perched.
Back-stacking Behavior
Back stacking is actually a sensible adaption to the Harris’s Hawk’s wide-open habitats. The hawk on top gets a better view for hunting, making up for the lack of elevated perches in the landscape.
