Well it's been fifteen days since I placed the sawn-off tree trunk on a table outside and while occasionally I would see a bird on it, between the time I reached for the camera and arrived at the window, the bird would disappear.
Today, I finally outwitted a bluebird. I think adding sunflower seeds to the suet atracted a greater variety of birds, so the spot became more attractive.
This was shot through my kitchen window. (I'm going to have to figure how to get a darker colored suet mix - it's always overexposed if I want the bird exposed properly!)
