Whisky - bird food?

This morning I had put put some crusts from the bread for the birds on the deck rails. Whisky had to have a look to see what it was, this the rail that she gets up onto to jump through the kitchen window. Then the next thing, she was licking it, but I missed that shot. Tried opening the window, but she just wanted to jump through it. So I was mean, and shut it again. This this her, taken though the window.
