We've seen Thomas

04 Jun 2019 Thomas has been pretty faithful to the Cranwich Heath area but he has also ventured further south. Whilst out birdwatching at Lakenheath Fen in May, two members of BTO staff saw a tagged Cuckoo, and looking at the data Thomas has visited the area a few times. However, whilst out with the Cuckoo team on Cranwich Heath we saw him again, determinedly chasing another male Cuckoo and a female. In 2018 he left for Africa on 14 June, so he may not be around the heath much longer.
