Distribution of Great Tit during a wintering in Novosibirsk. - D.V. Yudkin, V.A. Yudkin. - Berkut. 11 (1). 2002. - P. 98-104.
In 1999–2000 and 2000–2001 from 15-th October to 30-th April, the censuses of great tits were carried out in typical urban habitats. Mass appearing of great tits in city begins in September. In autumn warm period they concentrate on areas with developed tree vegetation or bush vegetation. Birds begin to move to areas with many-storied buildings after the beginning of frost. Constant resource of anthropogenic forage cause large concentration of birds here (more than 1000 ind./km2). During a winter we observed several complementary appearings of great tits in city. Spring migrations begin at the end of winter and come to culmination in March. Preference of habitats changes in this time. Birds leave areas with many-storied buildings. Tits, which move through the city, are observed on areas with trees and bushes. To April the number of tits in city sharply decreases. [Russian].
