System (*Changed in 2010)
Each bird that follows the ultralight on its first migration has a
number that becomes its "name" for its whole life.
The number tells something about the bird. The bird's hatch-order
number is first, with the hatch year at the end. So the third bird
to hatch in hatch year 2010 is named 3-10. Gaps in the number system

naming system is different for birds led south by ultralight in
the Classes of 2001-2009, when the first digit (9) stood for the
hatch year and the last two digits indicated the order in which
that year's chicks hatched. In 2010 Operation Migration and Journey
North switched to follow the WCEP naming style that now applies
to every bird in the reintroduced Eastern Flock of Migratory Whooping

they reach Florida, half of the Class of 2009 will land at
St. Marks National

will migrate back to Wisconsin each spring, and to Florida each fall.
(They may disperse to a wider range as they get older.)
Eastern flock's Two Winter Homes
crane in the new Eastern flock wears leg bands on each leg. Like
names for humans, color-coded bands identify each crane for life. Detailed
histories are kept on each of these endangered birds, and the banding
codes help scientists tell the birds apart. ICF's
Sara Zimorski explains
the colors: "Red, white, and green are the three brightest and most
contrasting colors. They show up, are easy
to tell apart, and are not easily confused with other colors. That's
them for our color scheme. As a bonus, each bird has all three colors
so if we ever see a bird with only 2 colors
we will immediately know a band was lost. (Only one bird has lost a band
since the start of this project in 2001.)"

birds will get yet another band and transmitter (PTT)

permanent bands with color codes are attached to the birds'
legs at the health checks after they arrive in Florida and before
the top net is removed from the pen for their final release.
