Why North
America’s Gangliest Bird Is Hitching a Ride With the Coast Guard
Whooping
cranes are on the move, because of budget cuts.

AT FIVE FEET TALL AND a
whopping 17 pounds, whooping cranes are one of North America’s biggest,
heftiest birds. They have their majestic moments, but they’re also rather
gangly and awkward. Their spindly legs trail after them in flight, their call
sounds like a mangled bugle, and their black wingtips appear to splay out, like
a gloved dancer’s spirit fingers.
This
week, 33 of the rare birds are migrating, but they’re not using those wingtips.
They’re flying with the U.S. Coast Guard from Maryland to Louisiana, where they
will settle into a new home at the Freeport-McMoRan Audubon Species Survival
Center. (A handful of them will eventually reside at some Texas zoos.)
Over the
past two centuries, the cranes have had a rough go of it. Their range once
stretched from Alberta, Canada, to the southern shore of Lake Michigan, with
winter colonies in Mexico and on Texas’s Gulf coast, and scattered clusters
elsewhere. They breed in the shallows of grassy wetlands, and as those
landscapes shrank, so did the flocks. In the mid-20th century, when there
were fewer
than two dozen of these birds left in the wild, the species came
vanishingly close to oblivion.
To keep
the population aloft, teams at the U.S. Geological Survey’s Patuxent
Wildlife Research Center in Maryland have spent the last five
decades breeding and rearing the birds. They began with eggs
collected in Canada’s Wood Buffalo National Park. Ever since, the
goal has been to stabilize the population and prepare their feathered charges
to leave the nest without too much human-ness rubbing off on them. The
surrogates raised roughly 30 chicks a year with the help of some unorthodox
tactics, including donning crane
costumes, using bird puppets, and teaching
fledglings to flybehind an ultralight aircraft. The
project’s $1.5 million budget was a casualty of federal cuts last year, and now
the remaining birds are en route to new homes.
