Nothing complicated. This is my kitchen window. As you can see the suet cake it hanging outside the window from my gutter. If I see a bird I like out there, I walk up to the window and the bird usually flies away. I then set my iPhone 7 on the top part of the frame of the bottom window and zoom in on the suet cake. I then stand to the side and wait for the bird to come back. When the bird comes back I can usually snap off 5-6 pics until he figures out I am standing to the side. The distance between the suet holder and where my camera sits is only 11". It looks closer with the zoom. And before you ask - yes I am working from home and I do need to get a life.
