A few more birds I don't recognize

Hey all,

I've been hearing some more new birds yesterday and today that I don't recognize.
I did see a small bird where the sounds were coming from, but it could also be the Chaffinch you hear in the recordings.
If it wasn't the Chaffinch though, perhaps it's just 1 bird making all these sounds?
