First the bad news: birds are always trying to come into my house through the window. The window is not open so they usually are in for a big surprise when they don’t get in. A little bird tried to get in the other day and left his mark on the window. The good news is he (she?) seemed fine and flew away. The feather left stuck to the window is about half an inch (about 13 mm) long and I wanted to get a shot of it. This was shot from the opposite side of the window that the bird hit. The equipment I used to get this shot was the Nikon D600 with 100mm macro lens, 3 extension tubes and a focusing rail, all mounted on a tripod. This was only the second time I used the rail and it works very well. Both the tubes and the rail came from Amazon, which gets them from Adorama only Amazon offers free shipping.
