Accipiter cooperii

Generally migratory from N half of range, but some birds remain even at N part of range. Sedentary elsewhere, though birds at high altitudes may move to lowlands. In autumn, yearlings migrate first, and females precede males in each age category; migration late Aug-early Nov, with peak from mid-Sept to mid-Oct. In spring, males precede females, Mar-May. Migrates commonly to Mexico, but as far as Costa Rica and rarely Colombia.
