Based on the research I did on these birds, I believe they are Long-billed Dowitchers. There is a Short-billed variety also, but their coloring most matches the pictures of the Long-billed I found on the internet. This picture is from May 7th, the evening I went to TRNWR and found the ponds drained. It was also my first time there since the refuge allowed visitors to walk the roads after the winter. This allowed me, for the first time at the refuge, to get close enough to the shore birds to take pictures of them. I have several pictures of them and haven't gotten through most of them yet. Hopefully there will be some even better ones.
