Bringing
Back the Cranes
These are historic times for endangered Whooping Cranes! The
fragile population is slowly climbing from an all-time low
of just 15 wild migratory cranes alive in 1941.* The long-term
recovery goal for Whooping Cranes is to establish a self-sustaining
population of a minimum of 1,000 Whoooping cranes in North
America by the year 2035. How is it going so far?
Western
Flock: The Only Natural, Wild Migratory Flock
Those original 15 survivors were part of the Western
migratory flock. The natural flock's
population passed the 200 mark in 2004 and the 250 mark in
2007! These cranes migrate between their
wintering
grounds
in Texas to their breeding grounds in Canada's far north. More

Eastern
Flock: The New, Reintroduced Flock
In the eastern US, a second flock is off to a good start. The
Eastern migratory flock began in 2001 from 11 chicks
bred in captivity. With no wild parents to teach the way, new
captive-bred chicks added
each
fall learn
their
migration
route by following ultralight aircraft on their first journey
south.
Each spring
we eagerly
wait to see if, when, and how the youngest crane-kids return
north — unaided, wild and free. The goal: 25 breeding
pairs from 125 birds released in the Eastern Migratory Flyway
by 2020, with 18-20 chick introductions each year.
Tracking
Two Flocks
Each
spring, we track the migrations of both migratory flocks. Our
dual migration coverage examines these question:
