With this data, scientists can gain a fascinating insight into the migratory routes that these birds take, how long they can live for, survival rates, a whole host of key information. And by understanding these factors, they can begin to understand how it affects population trends, which in turn provides knowledge that is vital for the future conservation of birds such as the pied flycatcher.
It's because of schemes like this, carried out by Clive and Dave, that will hopefully ensure that these birds will be returning to Lyme Park for many years to come.
Pied flycatchers aren't the only birds of note recently seen at Lyme. Sightings of wood warbler, garden warbler, redstart, stonechat, wheatear, grey wagtail, green woodpecker and yellowhammer have also been reported. If you see any other notable sightings, please let me know on john.mead
