Most of the above but, as mentioned, blackbirds are much rarer. Cats without bells on collars are a scourge and menace, maim and kill so many birds (and mammals, amphibians)… -
That seems more like the initial reports, where the beeping appears to be clearly heard but difficult to locate. I don't know what experiments would then be useful. I'd suggest something like: go to the area at night when there's little other noise. Have with you any of (a) a stout tube -- apply to one ear, block the other; (b) some electronic recording or audio-sampling device(s). In both cases they could be used in different locations and/or orientations (principally rotation about a vertical axis), with a view to finding variations in perceived or received intensity. Maybe take someone with you to video the proceedings. 🙂 -
Agree, the merlin app is really useful, especially if you are bird spotting somewhere like Greendale where it's much easier to hear birds than see them! Once you've learnt a call you can look out for the bird... Sue – I saw a pair of long tailed tits in East Dulwich Grove yesterday : ) -
I may have found the cause. Popped up to Erics this morning, and just opposite the Jewellers I heard the beeping. Stopping there for a few minutes I pinpointed it to either the beige campervan , the trailer or the building they are both parked outside. Acoustics make it hard to pin down exactly.
