Below is the gang all together. There were many pods of birds like this all over the refuge.
Most of these water birds were shy. I never did get a decent shot of the coots without them paddling like madmen/women to a far shore! You can tell by that bird in the lower left, I am not welcome.
I tried to get some photos of these shovel bills, since I do not have any of this duck, but they were also shy and rarely had their head above water and this photo does not do justice to their colors! Actually they are probably packing on the carbs for the long trip ahead.
Finally, I did get one shot of pintails with the male showing that lovely blue bill and you can see why they are named pintails.
