I spent the past weekend up in Maine, for my first session of the year with the cameras, including a visit to a friend's feeders. He has had up to 20 Pine and many more Evening Grosbeaks...but it was quiet when I was there. However, the Pine Grosbeaks did briefly visit but mainly fed on the ground (which was 2-3 feet of snow). I managed a couple of images in very low light.
1/250, f8, ISO800, 80% frame. Flash @ -2/3 (with AV ETTL).
