Now Hear This.

I put my AudioMoth sound recorder out again last night. Quite a lot of Owl action again (Tawny I think). At this time of year, the expectation is Redwings as they are known to migrate at night and call to each other as they do so. I got several of these blips on my sonogram in the early hours, which, I know, is what a Redwing call look like, but sadly I couldn't hear them - too high frequency for my deteriorating hearing!
