I use my daughter's old trampoline as a bird food distribution area. It seems to keep the rodents from getting to it.
Just now, I think that I may have had a young Raven on the birdtable. I have never seen a Raven around here before (or I had failed to identify them). Is it possible? I did not have long enough to go and get my camera or phone to photograph it, but it had a longer head, than a Crow, or so it seemed. It was not as abrupt between the bill and the rest of the head.
I love Corvids, but I do sometimes have difficulty identifying them. The problem is photographing them, as they fly off at the merest movement inside the house, let alone outside.
