Three hour chortle

Been trying to catch this chorister, for 3 mornings, he/she starts about 6am.  I was sure it was a Thrush but light and distance so bad I couldn't see for sure until I cropped it.  A wonderful lengthy song, it was singing  until near dark too.  Extra a tree full of crows....  I had to take Ced to Belford last evening as he slept all afternoon, and had a mystery high temperature, when he woke.  After many tests looking for some infection, they think all connected to chemo.  Touch and go as to whether he stayed in but I brought him home at 11pm.
