This little hummingbird has a piece of thread or string wrapped around her leg. Believe it or not, this little female has been coming to our feeder for the last four summers. I don't know how long these little birds live on average, but this one is at least four years old. I can't imagine there could be more than one bird with string around it's left foot and leg. I was amazed last summer when she showed up for the third time, now I am in awe of her strength and tenacity. I hope to get a good close up of her shortly.
