Is any one getting any indication from anywhere of anything?

I had a very large bird on my windowsill yesterday, chirping away quite animatedly. I can't really make out what he is saying, but he sure seems excited. Maybe with a hint from somewhere else, I will be able to decypher it.

It is not the infastructure bird, as he is blue, and drops in regularly, and prefers sunflower seeds, nor is it the financing one which is mostly grey with yellow wings, and was here all winter, and really likes suet.

This one is larger, brown, with an orange head, and I haven't seen him here recently. I can't determine what he eats though, and their chirping only becomes legible on a full stomach. Any hints to feed him with may help.

Best regards

K
