• The goal is 25 breeding pairs from among at least 125 Whooping cranes for the new Eastern flock to be self sustaining. WCEP experts hope the goal will be met by 2020. List factors that are necessary for this goal to be reached. How do you think the flock is doing?
• For the past two years, some very hot weather happened when several crane pairs were already incubating eggs on nests. The heat promoted the hatching of pesty black flies that tormented the cranes. Cranes got off their nests in efforts to escape the biting flies. If this is indeed a cause of nest failure, what ideas might help the problem?
• WCEP scientists are researching the nest failure problem. They will release their results in September 2009. Read some early thoughts by Joe Duff and compare with your thoughts. >>
