There's been a lot of birdsong going on here in the last month or so. Not in the early morning but through the night. Around 1 am to 3 am there's been one really distinct singer who's song was amazing. I wish I'd recorded it because whatever type of bird it was, it's moved on to somewhere else now. I'm not sure but I think it might have been a robin? Going to do some searching for sites with birdsong recordings. If I heard it again I'm sure I would remember it. Cheers! dave.
