We saw these turkey vultures flying over Lake Mathews Dam a few days ago. My wife had her camera with her so we decided to stop and take a few pictures.
We were curious about the bird with the wing tag so I consulted google and found a conservation site that had pictures of other turkey vultures tagged with white wing tags. I eventually found out that this bird was tagged in the summer of 2009 either at Irvine Lake in Orange County or at the San Jacinto Wildlife Area.
I also found a site operated by the U.S. Geological Survey that lets you report sightings of tagged birds. So if you see a tagged bird, visit www.reportband.gov/.
