Mark F. and all.........What Mark saw on the turkey vultures was wing tags; a form of 'bird banding'. Too bad you did not have your binoculars. With the bins you could have possibly read the information on the band. Buzzard wing tags are fairly large. You can see some examples at: http://bandinginsask.blogspot.com/2009/08/wing-tagged-turkey-vultures.html Also check: http://vulturesociety.homestead.com/Sightings.html Bird band (tag) reporting: http://www.reportband.gov/ Tom Teeples 28 Fox Tail S Irvington, VA 22480 Home: 804-435-0636 Mobile:804-381-1795
