Description

It may be the worst photo ever, but hopefully you can make out the rat in the middle of the crop from phone camera. I saw several during a 5 min bird count. Lots of (wild) walnuts around I I think they were feeding on the nuts. This one was clearly a big, ugly, rather beat-up male.

Dead rat in trap. Been there for a while as I hadn't been out to check the trap due to the continuous rain.

Probably Rattus norvegicus from the looks of remains of the tail.
