Pengelli -- Blue Tit productivity & ........

This year two plots each of 25 nest boxes have been studied. c3/4 visits have produced the following data;-
Plot A;-
Of the 25 nest boxes, 7 have been occupied, 6 by Blue Tits & 1 by Pied Flycatchers.
The 6 Blue Tit boxes produced 41 young, an average of 6.8 per pair. With a range of 10 young in 1 box to just 1 young & 3 infertile eggs in the least productive.

The Pied Flycatcher's produced 6 young & 2 infertile eggs. A 2nd male Pied Flycatcher, un-paired, presumably a 1st summer (not a striking male plumage) appeared to be helping with feeding the young?

Plot B;-
Of these 25 nest boxes, 10 were occupied, all by Blue Tits, with a range of 12 young being the most productive, 3 being the least, with an average of 7 young.

A final visit is to be made this w/e to ensure we complete the results, & maybe collect some nest fleas?..........any takers ...apart from Janet!
