The Common Cuckoo Cuculus canorus become increasingly rare at the lake since the start of the century, so I'm gathering as many records since 2000 as I can to see if this is actually the case. There was certainly a drop in numbers recorded but in the last few years there does seem to have been a slight turn-around, but it will be interesting to see if this is maintained. If you can add to these records, please send them for inclusion.

Andy Davis wrote that Cuckoo is "probably under-recorded with only 15 records..." in the 20-year period covered in his paper (1963-1983). So, it would appear that it has not been particularly common at the lake in recent decades, though there were 5 birds on 2nd May, 1964. Davis also records sightings of several juveniles including one with a Dunnock Prunella modularis. The British Trust for Ornithology has been radio-tracking Cuckoos in a bid to understand why they are declining. Today, the Cuckoo, once such a familiar harbinger of spring, is undergoing a rapid decline in England and moderate decline in Europe.
