Missing migrants

This year St.Ives appears to have missed out on some birds it used to attract.
Redstarts, Tree Pipit, Wood Warbler, Cuckoo and Pied Flycatcher all used to be annual visitors. Pied Flycatchers were hopefully going to be encouraged back into Cuckoo Nest Wood with the erection of about 200 nest boxes. In 2007 we did get a male singing for about ten days but he didn't return this year. The first four mentioned have been missing for a few years now with only Wood Warbler putting in appearances though these have finally dwindled to zero this year.

On top of that this year St.Ives didn't have any singing Garden Warblers at all to my knowledge. Though we have gained Whitethroat these are only turning up and singing and not holding territory.
