Hello, could anyone kindly help me identify the attached song ... actually at first I wasn't sure it was a bird at all, maybe a whirring insect, which points me to a possible grasshopper warbler ?
Not the chiffchaff, but the background whirring
Many thanks
Jon

thanks Wendy, not sure if these 2 short clips help or not - there's not so much over-singing chiffchaff (tho a background engine towards the end)
