White pelicans, while not really uncommon in these parts, are not nearly as ubiquitous as the brown which right now are seen by the many thousands. Oddly, it is the brown that was listed as endangered, something hard to fathom with the large numbers here, and the white is of "least concern."
On another note, I'm curious as to why this image looks soft as I was excited to get a sharp image of this white pelican from my kayak as it was suddenly flying overhead. Oh, well.
