FLORIDA!
Nineteen
whooper chicks arrived
Dec. 13, 2005 after a 61-day migration led by ultralight
planes.
They came from Wisconsin, where they had learned to
fly and where they will return each spring for the rest of
their lives.
|
This
year the chicks stayed for a month at a temporary site. Each
one had a medical exam and
got permanent leg bands. Doctors first put a hood
over the crane's head. The birds must not
see human faces or hear human voices. They will go
to their final winter site after all the older cranes disperse.
(The older birds pick on the chicks.) |
All
the Eastern cranes wear radio tracking bands on one leg. In
addition, two of the chicks were now fitted
with PTTs (satellite
tracking devices) on the other leg.

On
January 9, 2006, the pilots tried to lead the chicks the last
few miles to the normal wintering area. The ONLY bird willing
to
follow
the ultralights on January 9 was #508! |
After
three days of trying, the pilots managed to get all but one
chick to follow them to the final goal— the pen at "Chass." The
only bird not making the flight was #516. |
For
the winter, the new arrivals will freely come and go from
their predator-proof pen at Chassahowitzka ("Chass")
NWR. They will learn about tides and catching blue crabs. |

The
older birds usually spread out in nearby counties, or even nearby
states. But sometimes they come back to get free food! They may
fight with
the chicks, or try
to drive them away. It's best if only the
youngest chicks are at the pen site. This year #309 lived
with the chicks, but she is meek and doesn't bother them. Photo WCEP |
The
open-topped pen is made of 8-foot high fencing. The cranes
can come and go as they like. The bottom of the pen is alligator-proofed
with heavy wire screens. Electric fence wire discourages
other predators. Much repair work was needed after the recent
hurricanes.

A
member of the monitoring team (this is Sara)
makes the 40-minute airboat ride to the cranes' island each
day. Monitors check on the birds and their food supplies.
They keep them safe by setting live traps for bobcats. They
write notes
on
the
cranes'
behaviors.

The
crane monitors (this is Sara
) can hide in this blind to watch the cranes. They
come twice a day to the island. A solar-powered video monitoring
system helps keep watch when the humans aren't there.

goes to the blind along a board path
that keeps her from sinking into the thick, black, goopy
mud.
Caretakers
spend as little time as possible with the cranes. These
birds must remain wild to have the best chances for survival.
|
Decoys
like this one have been with the cranes since
they hatched. The decoy is familiar to them, so the young
birds feel less nervous in their new surroundings.
The
cranes never see a human form without the baggy white costume. |

A
feeding station inside the pen provides a constant supply
of high- protein crane chow and fresh water. A small roof
keeps rain out.
The
new arrivals--the 2005 chicks--are free to fly, play, and
explore during the day. Which

Which
cranes can you identify by looking at the colored leg bands?
(See 2005
Banding Codes.)
The
chicks will get their adult voices during winter. They
will get whiter as their rusty-colored chick feathers get
replaced.

The
chicks are led into the top-netted area at night—and if
the older cranes come around to bully them. The birds
must be safe from predators AND from the
older cranes who may claim this as their territory.
The
top net is high enough so the birds can still enjoy leaping
and jumping. Photo
