At this time of year, the reserve’s blue tits are looking for nest holes in our old trees. The ash tree at Fiveways harbours a nest every year and the newly fenced oak near at 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.
