With migration curtailed by several days of strong easterlies (strong enough to bring a tree down on the Bustard-mobile, but that’s another story!), and many thousands of soaring birds anxious to make the journey south, this week it became a little like a crowded airport departure lounge here in the Straits!
Flocks of Black Kites and White Storks numbering in the thousands have been tumbling up and down the coast, and hanging in the air, making it look like someone just shook a snow globe!
When your journey’s delayed by bad weather, there’s only so many times you can visit Sock Shop and Sunglasses Hut. After much milling about, these birds have been collecting in huge super-flocks in the valleys – presumably the equivalent of the Wetherspoons!
But today, as we sat down to monitor the migration with our conservation partners Fundacion Migres, it became apparent that the great air-traffic controller in the sky had finally granted them a clear take off to Morocco!
The Straits of Gibraltar is one of the greatest bottlenecks for the East Atlantic Flyway. The Black Kites zooming over our heads have come from all over Western Europe and move south across a broad front, crossing here and at Italy’s Straits of Messina. White Storks are more reliant on soaring, and find the sea at Messina too wide. The entirety of Europe’s migrating population will cross here.
For the White Storks it’s a relatively short-haul flight, for a winter break in North Africa. The powerfully-flying Black Kites head further, across the Sahara to countries like The Gambia and Senegal. They will be the first to return, and we look forward to seeing them arrive from February onwards.
Our day passed in a whir of clickers and plenty of exclamations at the sheer volumes of birds swirling past us. We finally had a chance to take stock for a moment in the afternoon and realised that we had already counted 18,000 birds! Yes, eighteen thousand! By the time we left, we could see black-and-white blobs before our eyes and our final count was 19,488 White Storks, Black Kites, Booted Eagles, Short-toes Eagles, Montagu’s Harriers and Egyptian Vultures for the day!
Days like this happen throughout the Autumn (and Spring!) – if you’ve not experienced this yet (or even if you have!) then you should head for a departure lounge near you and join us this August for some serious #FlywayBirding!!
