It was a rainy day and I spent it helping set up our new A/V equipment in the amphitheater. It's pretty sweet, and we even rocked out to some AC/DC for our test of the 1000W speakers.
On the way back, we saw what looked like a plastic bag stuck in the grass next to a bison. At the same time, Dave and I said, "Hey, that's a cattle egret!" There were two following the bison very closely, picking out bugs that the bison stirred up, I guess.
While not unheard of in North Dakota, the Sibley Guide to Birds puts them at an infrequent status, but Cornell puts them in their winter range here. I don't know if I believe that. I've certainly never seen them in ND before.
In North America, I've only ever seen cattle egrets in Florida. We did see plenty of cattle egrets in Africa last fall.
