I have seen something similar on sandhill cranes.It looks like a tag that is attached in some loose skin that is near the elbow joint on the top of the wing. It is large enough to read from a distance with good optics. Letters like the T can represent which nesting colony it came from. The color of the tags can be changed so that each year of the study is a different color. They have had some fairly intense studies of the nesting colonies from the islands on the great salt lake. If you wold like I can probably get a little information from a friend of mine. Did you check the legs for a federal band like they put on waterfowl? gshorthair
