Bird Sounds

Now the geese have subsided the sounds of other birds and things penetrate
and confound.
IS there a CD or something on bird sounds of Caithness or Scotland available?

There is one that sounds like a paper and comb or wind blowing through a wind break or something .Any Clues?

And do we have crickets here with extremely loud legs?

The Sedge Warbler sounds a bit like that.

Check out the RSPB site they have several recordings of bird song think also The BBC covers some .
