We have a lot of robins here in north London, but I'm trying to work out if this song I heard the other day was one of them. Here's a recording: https://drive.google.com/file/d/1JEE0FB2Ghxmt9KXkvkd98m4B4ybdPv10/view?usp=sharing
It's a peculiar clicking and squeaking sound. What makes me think it's a robin is that there was one nearby as the sound happened, and when the robin flew off the sound went too, but I suppose that might be a coincidence (perhaps the robin chased off the click/squeak bird).
The other small birds we have here are great tits, blue tits, coal tits and the occasional group of long-tailed tits, sparrows, the odd blackcap, and I think I saw a female reed bunting the other day (it didn't look quite enough like a sparrow anyway). So it could have been any of those I guess, or something else. We have mixed seed, sunflower hearts, nyjer seed and fat balls in the garden.
So, can anyone tell me if robins make this sound? Thanks for any answers!
