Interaction between different species is one of the most interesting aspects in the studies of animal behavior. A deer can calmly graze and does not run away until a predator shows hunting behavior; also, interspecific competition can cease if the food resource becomes plentiful. Many of bird species are subject to predation. For example, pheasants may be prey to tigers and leopards in Primorsky Krai. But it turned out that pheasants regularly fly into Filippa’s enclosure and show no fear to the young predator. Besides pheasants, black crows are also frequent visitors that even attempt to compete with the little tigress for her food resources. Corvid birds are common companions of all large predators in the wild. A large flock of black crows has settled in the territory of the complex of enclosures. The species structure of bird population here changes during a year: in winter, these are mostly black crows, magpies, nuthatches, and various titmice; azure-winged magpies arrive in May. Birds constantly “interact” with the predators in their enclosures. Thanks to them, the young tigers learn to hide their prey, as crows easily steal uneaten pieces, as well as work out their hunting skills (by looking for, ambushing, and chasing the flying guests).
