| Chick #401 hatched (video clip) out on the morning of April 20th at the USGS
Patuxent Wildlife Research Center. Congrats to the crane crew at
this largest captive breeding center for Whooping cranes! |

This photo provides an excellent view of the
chick-rearing setup at the USGS Patuxent
Wildlife Research center. In the foreground is 6-day old chick #401
eating crane-crumbles. The puppet head, suspended over the feeding
dish, is to encourage HIM (confirmed - it's a boy!) to eat. In the
coming days, a similar puppet head will be used to encourage him to
follow the ultralight aircraft as it taxis slowly around a
circular-enclosure (video clip). The heat
lamp provides warmth for the tiny chick. The adult role model in the
adjacent run is crane #6 from the 2002 hatch year. #206 was held back
at the captive-breeding facility due to a very early wing injury,
which would have limited its ability for flight. Since 206 had already
undergone some early aircraft conditioning, this crane is now being
used as a role model (video clip) for new
WCEP chicks to ensure correct sexual imprinting occurs. Also in this
photo, you can see the head of the plastic crane decoy. These are
suspended in each of the chick pens so that the young cranes become
familiar with it. Once the chicks are transported to Necedah NWR in
Wisconsin in late June, these decoys also make the trip, and will be
placed inside the roosting areas of each of the three training sites,
which will make the transition to the new area a bit less
stressful.

This WCEP Whooping crane chick was the fifth the hatch for the 2004
project year, and as such gets the number 405. Notice that #405
has tiny wood splints taped to its middle toes? This is done to ensure
the toes form properly and prevent them from curling under.
Deviated or crooked toes are frequently encountered with
hand-reared chicks at any age prior to fledging. Hand-reared chicks
under 10 days of age frequently have one or two bent digits. To
detect the problem, the crane crew at Patuxent must observe the gait
of each chick daily; *the middle toe should point straight forward
with the other toes pointing approximately 45 degrees to each
side.
Toe misalignment can be corrected with a splint; sometimes only 1-2
days of support may be adequate. Splints made of small wooden dowels
or popsicle sticks are taped to the crooked toe using low-tack tape
such as the filament packing tape used above.
