500 black storks migrate in one day

OVER 500 black storks have flown over the Straits of Gibraltar in just 24 hours – almost a quarter of the migratory population.

Sightings were reported from Algarrobo to Algeciras and in Tarifa, with the skies darkening as the storks flew over in between.

The Black Stork Ornithological Association said this sort of migratory behavior is unusual, but was likely determined by optimal weather conditions.

The association is conducting a census of black storks and fishing eagles as part of a six-week international project that will end on October 15.
