A map showing the migration of Cuckoo Jim from the UK to Africa and back again, with his current location in the UK. A headshot of Cuckoo Jim features, alongside the wording: After making his way steadily north through France, Jim launched across The Channel from Bayeux and arrived on the coast near Worthing on 16 April! From here, he headed to West Sussex, and is just 7 miles from where he was tagged last May.

Another BTO Cuckoo has touched down in the UK! 🙌
