The following was posted under the comments section of my post titled "Texas Pterosaurs" today:
"In 2007, my brother was talking to a man and his son that my brother occasionally worked with that lives in his trailer park in Edinburgh, Texas. The man and his son said they had been fishing in the canal behind the trailer park the weekend before. They said a giant bird landed in the canal a hundred yards from them and was wading around in the water apparently looking for food. The bird saw them and it wasn't afraid of them. It was wading towards them. The man said it was big enough to easily carry off the son, and they got scared and left. The man told my brother they will never fish there again."
Since this was posted as a comment anonymously I have no way of contacting this person to ask any follow up questions. Obvious things like color, estimated size, was the head of the bird feathered or bald, how long were the legs of the bird in relation to the rest of the body, etc. will remain a mystery. Since this is a second-hand report, these questions would likely have remained unanswered regardless.
As always, I cannot vouch for the veracity of reports that come to me in this manner. While I have no reason to believe this person is pulling my leg, I can't guarantee it. That being the case, take the report for what it is.
If there is anyone else out there that has seen an unusually large bird I would like to hear about it.
