Priory Country Park Tit Boxes

The Great Tits are a week ahead, or more, of the Blue Tits which has enabled them to fledge (or be large enough to be generating their own heat) before the recent bad weather. On nest box evidence, the Blue Tits have been struggling to cope with the rain (4 dead pulli having been found in 2 nest boxes - 2 in each). Brood sizes are smaller than when we first checked the nest boxes (particularly Blue Tit).
