I was able to get onto the Special Use area of the refuge yesterday, this is an area that is normally closed off to the public, and I went for the express purpose of taking photos of eagles. They migrate here for the months of December through February and then they head back north.
I know Paul is laughing at my photo of these eagles but this is as close as I could get all afternoon. And this was taken with the Sigma 150-500mm at 500mm! I only saw four eagles as it was and two of those were young, immature eagles that hadn't gotten their white feathers yet.
Since I couldn't get any closer to the eagles I had to resort to taking a photo of the moon. It cooperated more than the eagles!
