I guess my question is why isn't this a black bodied yellow bird? These birds seem to be very territorial. They are lined up in the marsh about 25 yards apart. They have a very distinctive call that sounds like a squeaking or raspy gate and is quite loud. We were carefully watching the weather when we out with the long lens taking this photo and others. We could see the rain coming across the lake and just made it to the car in time to avoid getting a soaking.
