The first Cuckoo from the British Trust for Ornithology (BTO) Cuckoo Tracking Project to arrive back in the UK reached his breeding grounds in Wales over the weekend, researchers revealed today. The bird, named JAC, arrived near the Welsh town of Llangollen, marking the end of an extraordinary 12,000 km round trip between the UK and the rainforests of central Africa, where JAC and the other BTO Cuckoos spent the winter.

Large numbers of rare and beautiful Waxwings are heading towards the UK in what could be the first major arrival for a decade, say researchers from the British Trust for Ornithology (BTO). These pinkish, Starling-sized birds have swooping crests, orange, grey and lemon-yellow tails, and wing feathers with waxy red tips. They breed in coniferous forests from Scandinavia to eastern Russia and usually spend the winter further south.
