Ornithologists and naturalists – your help gratefully received. I am trying to determine a species of bird which has recently shown up in Islington, London.
It calls at 9 seconds into this recording, louder and lower pitched than all the other (presumably smaller) birds and it has a decending "cho-cho-cho-cho-cho-cho-cho-cho" eight notes. Sometimes the call can last twenty or thirty seconds, and there are long gaps between the calls.
– . If you click the placemark it’s also linked to audio.
