Phenology of the autumn migration of wintering birds in Ukraine. - V.N.
Grishchenko. - Berkut. 15 (1-2). 2006. - P. 176-193.
Timing of the autumn arrival of 10 wintering bird species is analysed. Data
were obtained from different sources: phenological questionnaire, literature,
own observations, unpublished materials. In total, more than 2,5 thousands phenological
dates since 1961 were used. Main part of them refer to 19752006. Dates
were grouped by administrative regions of Ukraine (Tables 110). For Bullfinch
and Waxwing phenological maps of the arrival were made (Fig. 12). Correlation
between times of arrival of several species was found. There are two types of
the correlation: chorologic (between average dates in regions) and chronological
(annual fluctuations). Migration of Bullfinch and Waxwing pass similarly. The
arrival starts non-simultaneously in different regions. Phenological maps of
both species have three main migration streams and two large lag areas (Fig.
12). Correlation between average dates in regions is very close (r = 0,714,
p < 0,001). Some general aspects of bird migrations are discussed. Phenological
maps of the arrival confirm migration of birds by the wide front with formation
of streams of migrants. [Russian].
Key words: Ukraine, migration, arrival, timing, phenological map, flyway.
