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
- stopover sites: important locations where birds pause between migratory flights to rest, refuel, and seek shelter
