I am really taken with the Florida anhingas. Here are a female (top) and male (bottom) taken today (5DSR + 100-400mm II). I must aplogise in advance that these and the following shots are all taken without a tripod, strobe lighting and are cropped and so are expected to be mushy. Despite that, you can see how sharp their beaks are for spearing fish.
Thanks Jack - I was so delighted to catch the anhinga in the act - it was a really good day today, bright sun and 70 oF, and amenable birds! It really gets my goat when there are posts that the 5DSR needs specialised conditions to take sharp photos when the opposite is true for most of the time.
