Distribution, numbers and some peculiarities of the breeding ecology of the Shag and the Herring Gull in the South-Eastern Crimea. - M.M. Beskaravayny, S.Yu. Kostin. - Berkut. 7 (1-2). 1998. P. 25-29.
The Shag and the Herring Gull form a basis of hydrophilous breeding ornithocomplex
of the Southern Crimea coast, where they inhabit rocky coast precipices and small
rocky islands. Seven areas of nesting of the Shag have been found (170-180 pairs):
the largest one at the Karadag Nature Reserve. For nesting wider range relief
elements are used, than at the North coast; inland components are used more often
to build the nests. Periods of the reproductive cycle vary within 2,5 months for
different pairs and starts at the end of February. The Herring Gull inhabits the
six main areas (about 150 pairs). Distinctive feature of biotopes in this region
is the significant development of relief vertical elements. The reproductive cycle
starts in April. During the last decade, invasion of new habitats and increase
of abundance at the South coast has been being observed. The food mostly consists
of animal organisms that are collected on the coastal zone. [Russian].
