reduced numbers of migrants. (1 Viewer)

Hello. First post for a few years. We have far fewer swallows, martins pied and spotted flycatchers in my area of mid Ceredigion than in other years. Has anyone else noted this lowering of numbers in their part of the British isles. The Pied flycatcher that uses the nest box close to the cottage returned this morning 6 weeks late. The cold spring is certainly a factor as is climate change. habitat degredation and urban sprawl but could a lot of birds have been displaced by any of the geomagnetic fields from the proliferation of telemetry used for monitoring remote infrastructure. I am aware of some problems of breeding birds in the vicinity of phone masts.

Hi audouin
I was at Ynsyshir last week and saw almost nothing. I have been about the same date for many years and I was amazed by the lack of birds of almost all species. The Dyfed Osprey site just up the road was the same.

The numbers of Swifts, Swallows and Martins certainly seem to have been low, or very late in arriving.
