Swamp guards alert birds that photographer is in the swamp.

While I was out shooting at the Cattail Marsh Scenic Wetlands and Boardwalk in Tyrrell Park in Beaumont, TX, these Black-Necked Stilts would be quick to spring from the marsh and to warn other birds that I was a threat.  They would fly throughout the nearby marsh screeching their warning.

They would also fly over me to take a good look and apparently to let other birds know of my presence.  It was a behavior I had seen in other areas, but these watchbirds were much more aggressive.

I was out at Cattail Marsh and caught this group of mud brothers trying to dry out with very little sun to share.
