Dear Bluesky-friends, I am back to ask another favour. Gull-billed tern chick H36 has died close to Parque Nacional de Doñana. It seems to be on a small island in the Caño de Guadiamar: maps.app.goo.gl/Z195ha4z9zYY...

After hanging out at Parque Nacional de Doñana for a while, it has now happened: gull-billed tern fledgling H13 is the first of our ‘logger-babies’ to have left Europe. Sibling H12 has made its second move to France today, while mum L09 is still hanging out in the Netherlands. #theygrowupsofast

Here’s an update on gull-billed tern L49, whose GPS showed us that it died in France while traveling south: although google street view suggested a power line might have been the problem, the corpse actually suggests that the bird has been shot.
