Re: BS migration
- the peak of autumn migration is in the second half of August
- the last autumn sightings occurred during the middle of September (Estonia)
- data suggest that two domestic factors might have a significant impact on their migratory success - body weight and longevity of stay in nest
- at least 80% of the black stork chicks perish even before they reach their wintering areas
- there is not evidence to suppose that juveniles travel together with their parents and or siblings
- black storks are mainly seen alone or in very small groups
- migration routes (flyway): western (via Gibraltar to Africa) - eastern (via Bosporus - Dardanelles or directly over the Sea of Marmara) and rarely southern flyway/Mediterranean flyway (via Italy or Greece and the Mediterranean Sea to Africa)
- stopover sites: important locations where birds pause between migratory flights to rest, refuel, and seek shelter
