Apologies for the terrible quality of the photos and audio.
I'm having a big problem identifying this bird found today in Southern Poland. It was flying through a group of swifts and swallows (I've added one photo of the bird in question with a swallow for comparison) and I managed to record a short snippet of its call.
Is there any chance of identification for this specimen? Many thanks in advance
