As others have reported, it seems there are good numbers of Pied Flycatcher and Redstart about this spring. My nestboxes in Littledale have not been too successful for these species over the last 2 to 3 years, with only 1-2 broods being successful. With my tongue firmly in my cheek, I have blamed this on other members of our group for putting up too many new boxes in prime habitat and stealing all the birds!
However, this year (with even more new boxes in other woods) mine are better occupied.
There are 39 boxes which so far contain 15 Blue Tit, 9 Great Tit, 5 Pied Flycatcher, 1 Redstart and 1 Nuthatch. 7 Boxes are unoccupied thus far (some of which have been seriously "squirrelled"), although there could still be the odd late starting Pied Flycatcher. It is unusual here to see more Blue than Great Tits. 2 of the Pied Flycatchers are only at the nest building stage and so may not progress.
Last year only 2 broods successfully fledged from the whole wood so let's hope that this year is better.
