Received this note from the Director of the National Wildlife Laboratory after I forwarded him the photos:
"Nice pictures! The birds are cranes 1291 (Blue / Red), 1337 (Yellow / Yellow) and 1350 (Blue / Orange). "
The first digit identifies their hatch century (21) and the second their hatch year (2 = 2002)."
"Bird 1291 is a male hatched 31 May 2002 at the International Crane Foundation, Baraboo, Wisconsin and was released 2 January in Lake County, just south of Leesburg."
" Bird 1337 is a female hatched in the wild in near Leesburg 3 March 2003 and bird 1350 was hatched 2 June 2003 at Patuxent wildlife research center in Laurel Maryland and was released 18 February at the same Lake County site as 1291 "
