The end of August is the peak of bird migration. Some have already flown away: cuckoos, swifts, and others are getting ready for departure by gathering in flocks, for example: starlings, storks, swallows. Most of the breeding birds in Poland migrate to Africa and to Western and Southern Europe. Only the Greenish Warbler, the Citrine Wagtail, the Red-breasted Flycatcher and Scarlet Rosefinch travel to Asia. The end of summer is also the period of flights. Birds that nest in Northern Eurasia migrate to their wintering grounds in Africa, and Poland is on the route of their migration. Such birds include, among others: Wood Sandpiper / Łęczak (Tringa glareola), the most common wading pool by the waters, periodic backwaters just at this time. Observation of rare species of birds that stop during migration and the sight of majestically moving flocks of birds is now a unique spectacle in Roztocze.
