Last rollers are observed in various places from middle of August up to the second half of September and the first ten-day of October. Average long-term dates of the last observation in separate regions fluctuate from 30.08 till 4.10 (Table). Variation (standard deviation) of times of departure fluctuates from 7,8 to 16,4 days in different regions, on average it makes 12,3 0,5 days (n = 25). Phenological map of de-parture was prepared.
