Nesting
At this time of year, the reserve’s blue tits are building nests in holes in our old trees. The ash tree at Fiveways harbours a nest every year and the fenced oak near the bottom of the Arboretum seems to have attracted more than one pair already.
Here is a video of a female blue tit building a nest while, outside, the male guards the site from marauders and thieves.

A lovely video. Our nest boxes are usually used by blue tits but recently one was taken over by bees!
What sort of bees? Pictures would be fascinating if you could manage it (sent to friendsofscp@outlook.com)
I may have photos, I’ll see if I can find them.
