The main orientation directions of the Yellow Wagtail during the summer-autumn migration in the western Ukraine are described in the present note. Western Ukraine is a territory, which is interesting and rather poorly studied in the respect of what subspecies of the Yellow Wagtail migrate through its territory and whether Baltic populations migrate here. Observations, ringing and migration directions studies, using special cages following the method of Busse (1995), were conducted on the territory of Cholginski ornithological reserve (50 km west from Lviv, 49.58N 23.28E) during ten years period (1995-2004). In total 10 313 individuals of the Yellow Wagtail were caught and ringed, while 63 orientation tests were performed, that included 58 tests that were statistically significant. We analyzed raw data using computer software Orient 4.0, Statistica and Quatro Pro 8.0 for Windows. The results confirmed two preferred directions of the Yellow Wagtail on the autumn migration. SE direction was more characteristic for adult birds, while SW direction – for young individuals. The M. flava thunbergi specimens were captured among numerous birds of the M. flava flava.
