The past few days have consolidated the latest trends observed, with A7 positioned at the entrance of the Azov Sea (presumably feeding on tons of young anchovies), A2 is still missing in action somewhere in the Black Sea, and J3 our most advanced juvenile in the same area of the Aegean as A5.
BREAKING NEWS!! A7, our ‘front-runnner’ who reached the Black Sea on 14 July to disappear immediately from our radars, has just re-appeared late this morning in the vicinity of the Strait of Kerch where it was detected at last by a coastal GSM sensor. We retrieved not just its current position, but also his stored SW/NE route across the Black Sea during the past 12 days. To our knowledge this is the first confirmation of a Yelkouan migration from the Adriatic Sea to the mouth of the Azov Sea. Our early hypothesis that this bird underakes such a long journey in order to take advantage of the millions of sprat (young anchovies) present until October in the northeast Balck Sea / Azov Sea appears validated. Hopefully A7 will continue to share with us his regular progress (will it enter the Azov Sea?) in coming days. We’ll keep you posted.
