Birds don't wait until our summer to breed and some of our species, like pigeons and cormorants, can start laying as early as January!
Our Blue Tits aren't as early as those species but do get a head start on returning migrants by laying from the end of April and fledging young as early as May. That gives us some busy sessions checking boxes and (digitally) filling out nest record cards to contribute to the national scheme.
We have a few boxes at a nature reserve, just outside Maidenhead. These boxes have had a good year, with all being occupied.

One of our boxes had the unwelcome attention of a Grey squirrel so we added protection to the front of the box to keep the chicks safe.
|A second front was added to this box to stop squirrels chewing their way through to the nest|
We ran three sessions at Wraysbury to continue our Constant Effort Site programme. Numbers were down compared with last year and we will have to await the national report to see how the site has faired compared with the broader picture.
Bedfont had two other interesting recoveries: a Cetti's Warbler ringed in Titchfield Haven National Nature Reserve last October. And a Bedfont colour-ringed, in 2019, Common Tern chick was seen down in Dorset this May.
