Hi all, my first post here. I am a keen garden bird watcher (read: I like to watch as I am drinking my cuppa!). I have a decent knowledge of the more common garden bird calls, however there is a new one I have been hearing for a couple of weeks now and I am scratching my head over it. I thought it could almost be a Great Tit but it's not really the same as great tit calls I usually hear. Merlin (I know it's not always accurate but still), doesn't even give me a suggestion at all! I am located in East Cornwall, and I have the UK and EU bird packs installed yet nothing.
It calls three times in this recording, and I have attached a screenshot of what the pattern looks like on Merlin.
