Michael N. Kochert Matt P. O’Connell 2013 Raptors are generally considered solitary predators (Schoener 1969), but occasionally they interact socially (Brown and Amadon 1968). Certain raptor species (e.g., Swallow-tailed Kites [<i>Elanoides forficatus</i>] and Swainson's Hawks [<i>Buteo swainsoni</i>]) concentrate in aggregations in response to localized, abundant food sources (Ellis et al. 1993). Many raptor species engage in group hunting (Ellis et al. 1993), and social foraging is a routine strategy for some species (e.g., Harris's Hawks [<i>Parabuteo unicinctus</i>]; Bednarz 1988, Ellis et al. 1993]. Raptors generally engage in group hunting to pursue elusive or large prey (Ellis et al. 1993). Occasionally individuals of conspecific raptors engage in play as a group sometimes involving chases of prey species (Palmer 1988). In this letter, we report interactions between a large group of Golden Eagles and a herd of adult and juvenile Rocky Mountain elk (<i>Cervus canadensis nelsoni</i>) in late autumn. application/pdf 10.3356/JRR-13-00027JRR-12-03.1 en The Raptor Research Foundation Interactions between a group of Golden Eagles and a herd of North American elk article
