We need your help - four of our satellite-tracked quail have gone missing in France! Any information would be interesting, e.g. if the signal comes from near a fox den, buzzard nest or hunting area 🦊🦅🔫 If you can recover the tag, we can re-use it - and you can name this quail 😉 Pls share widely 🇫🇷

To the birding community: one of our GPS-tagged redshanks was predated during its migration in France. We would be very greatful if we could have the GPS tag back and get as much information as possible from the bird! This is the last position: maps.app.goo.gl/jCWDXDfhnJPT... @genmig.bsky.social

Question: do I know anyone near Nantes who would be willing to pick up a dead gull-billed tern and its logger? L49 has sadly been killed near a road. I’d be very grateful for a picture and the logger and would of course reimburse postage.
