FCP 2021 1206 New lens, Very Cold and Grey Day

My 600 mm Zoom Lens came today. Without even reading the instructions I slapped it on and headed for my favorite Place. I captured Duck details I wouldn't have otherwise captured. I still cant get black type birds with much detail. I had trouble snapping at times from the cold. The lens is about 5 lbs. I got a good series of pictures of a Duck taking off from the water and flying to the other side of the Pond.
