Whitethroats were observed from April 39 to August 15, 1997 on an area of 80 ha located on the right bank of the Volga River (Volgograd City, 48°45′ N, 44°30′ E). Males on breeding grounds appear from April 30 to June 27, no male occupied another breeding area within the territory investigated. Females start laying eggs from May 14 to June 26. 77% of the chutches produced at least one fledged young. Two pairs committed the second brood for the season on the same territory. It was the easternmost case of double brooding in whitethroats. The postjuvenile molt begins at the age of 18 days and ends in 50-day-old birds. In the region under investigation, the season of postjuvenile molt begins in late June and continues to late August (about 70 days).
