Bird Nesting Report 2016 by Dr. Mike Hounsome.
"
The number of nests started this year (29) was higher than the average as was the number of nests with eggs (23) and the number of nests that successfully fledged young. But the number of young that fledged (75) was considerably lower than the average (88). Both Blue Tits and Great Tits fledged on average only three or four young."
