English: The rock dove (Columba livia var. urbana Gmelin, 1789) and the yellow-legged gull (Larus michahellis J. F. Naumann, 1840)
The rock dove (Columba livia var. urbana Gmelin, 1789) is a widespread bird of the Columba genus (Columba Linnaeus, 1758) of the Columbidae family (Columbidae Leach, 1820). The bird has long been domesticated and settled by humans throughout Europe. Eventually, the pigeons became wild again, spread widely in the world and became synanthropes, habitual inhabitants of towns and villages. Their plumage color is variable, especially in urban semi-wild birds — there are a total of 28 types of color, the so-called morph. The rock dove feeds mainly on plant foods: seeds, berries, fruits. In human habitation, it is easily adapted to eating food waste and grain.
The yellow-legged gull (Larus michahellis J. F. Naumann, 1840) is in genus Larus (Larus Linnaeus, 1758) of the family Laridae (Laridae Vigors, 1825). Distributed along the Black Sea coast. In adult birds in mating attire, the head, neck, nape, entire underside and tail are white. Beak and iris yellow, and red eye ring. The legs are yellow. The upper part of the body is light gray. Young birds have gray-brown plumage. Feathers of the upper part of the body are dark brown with light edges. The wings are black and brown. The tail and the base of the tail are white. Chest and sides are covered with brown spots, abdomen and tail are white. Beak black, legs flesh-colored, irises dark. Most of the food is fish and cuttlefish, less — mollusks and crustaceans. In addition, terrestrial animals from snails to small mammals, as well as grain, olives, figs, etc. are also important.
