Donna, thank you for looking and the smileys. I have a much lighter tripod and a monopod that I carry in my care, from now on. I rarely take my huge Tamron 150-600mm on a road trip. The yellow rump does have what looks like a little tear under his chin. I looked at another photo of him and magnified the area and it shows up. I did not notice it prior to posting it until you pointed it out. Thanks again.

Most likely he's been in a scuffle with another yellow-rump, Greg. The ones here are fighting themselves and other birds over the peanut butter logs.
