We got a fresh light blanket of snow last night which seemed to drive the birds away. Pretty windy so I went to the lake with the camera. Didn't see much, but, I got these shots of birds in flight. I was using the Nikon 300mm 2.8 with a Kenko converter. That lens weighs about 5 and 1/2 to 6 lbs by itself making it pretty difficult to handhold it and try to follow the flight and get a focus lock on the birds. Still its fun just to be out there. Not sure of what type of swallow this is. I think it might be a violet green.
Swallow 1/1250 f4 ISO 100
Great Blue Heron 1/2000 f4 ISO 100
Turkey vulture 1/200 f7.1 ISO 100
