“…Great Horned Owls rely upon a broad prey base that encompasses many invertebrates and vertebrates, including other species of owls (Cromich et al 2002, Artuso et al 2020, Reynolds et al 2021). For example, they have been observed feeding on a freshly killed Short-eared Owl ( Asio flammeus ; Bluhm and Ward 1979), and fresh remains of this species have been found in Great Horned Owl nests (Killpack 1951, Wolhuter 1968).…”
