Blue or Great Tit eggs
The only glimmer of hope was a singing Pied Flycatcher that was present, my first Linacre record since 2013. Whilst checking the nestboxes this nest was found.
Possible flycatcher nest?
As you can see, it contains a lot of dried grasses, so could be the start of a flycatcher's nest. Hopefully, when I return to check the progress of the boxes, there might be something very nice in here!
As always, the nests that were present will be monitored for the BTO's Nest Record Scheme.
