I am pretty sure that's not a robin. (Midnight Warbler Goes Missing.) The robin's song is more golden and playful I would say. I suppose it could be a tired robin. Am I an expert? No. I am however doing a 6 month stretch down Scrubbs Lane for a TDA with 7 other TIC's and I have seen Birdman of Alcatraz and I am doing a bit of the old birdwatching from my pad in here.
Could it be a blackbird? I will listen closely to the next one I spot and let you know when I get a chance to get on the library computer.
