About The Cover

Harris' hawk family in the Los Medaños area of New Mexico. These young individuals, atypical of most birds, will remain in their natal area and associate with their parents and siblings for up to 3 years. This social behavior, to some extent, is linked to the formation and success of cooperative hunting “parties.” See page 1525. [David A. Ponton, Mountain Route Box 93, Jemez Spring, NM 87025]
