After what seemed like a very long wait, the Cuckoo has arrived in the valley. Announcing its arrival with a rapid succession of calls at 4.50am from a perch on a tree somewhere along the Bure.
For many years the Cuckoo has arrived in the last week in April. The delay this year due to the cold spring that we have had. Last year it was not heard until 25th May, so we could count this one at least as “earlier than last year”. The British Trust for Ornithology tracks transmitter tagged Cuckoos every year, these can be seen via the following weblink; https://www.bto.org/science/migration/tracking-studies/cuckoo-tracking
