Saw one (I think a second, couldn't confirm) just south of FM 2979 near FM 362. We couldn't see a nest, but we watched it soar back and forth over a decent sized pond for a while before landing in a nearby tree and hanging out.
The pond had several small waterbirds, as well as a dozen or so White Pelicans! We were out looking for a reported eagle nest near an old fishery out that way, and saw the pelicans - had to do some quick google-fu to confirm what they were. Didn't see anything at the fishery, came back around to look at the pelicans and saw the eagle soaring overhead.
