Overnight call, Prob. Chiffchaff (1 Viewer)

I ran my overnight monitoring kit last night from the back garden.
It's unusual to get anything other than Tawny Owl and Robin from the House overnight. Plus Redwings later in the Autumn.

So this single call was a surprise for me. I'm guessing a Chiffchaff, Sweeoo call, but posting it in case anything else springs to mind. so hard for me when you can't see the bird or the context. (it could have been in nearby Oak trees, as opposed to flying over)

Sounds good for a sweeoo chiff call.

Agree.

Thanks both
