Observation details

At least three, possibly four individuals (singing males) in riparian bushland at the southern shore of the main basin, together with other migrating warblers, viz. great reed warblers, an eastern olivaceous warbler, a river warbler, two green warblers, one red-breasted flycatcher etc. Diagnostic characters well seen in all three individuals (also by means of ID shots), such as short primary projection, long bill with darkish tip, strong supercillium pronounced in front of eye, darkish legs (not pink or yellowish) etc, see photograph. All three males singing for times, two of them quite consistently during a period of about two hours (9:30-11:30). Although the singers clearly stimulated and triggered each other singing from a short distance of only six or seven meters to each other, they were secretive and skulky; their songs sounded rather uninspired, corresponding the typical subsong character uttered by migrators while slowly moving through the bushes (compare attached sound record). I’m well familiar with this species as a breeding bird from all countries of its European range (including Russia), as well as a common migrator in Central Asia.
