EMP Update Time!

July 1, 2017 

Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month, nesting season has come to an end. A huge thank-you to the staff of Operation Migration, the Fish and Wildlife Service, the Department of Natural Resources, the International Crane Foundation, and all of the volunteers who help us keep track of the cranes throughout the year. We appreciate your contribution to the recovery of the whooping crane eastern migratory population.

Population Estimate

The current maximum population size is 97 (44 F, 51 M, 2 U). This does not include 2017 wild-hatched chicks. As of 1 July, at least 84 Whooping Cranes have been confirmed in Wisconsin, 1 in Minnesota, 2 in North Dakota, 1 in Michigan, and 1 in Kentucky. The remaining birds’ locations have not been reported during June. See maps below.

Reproduction

This year, there were 37 confirmed nests by 26 pairs in Juneau, Adams, Marathon, St. Croix, and Green Lake counties, Wisconsin. Eighteen chicks have hatched from four first nests and ten re-nests. Six wild-hatched chicks are still alive as of 1 July.

    Not a real good survival rate going on.

    So that slow increase in the EMP that was going on has stopped since the Louisiana project began. What’s the crane population in Louisiana now?

    Hi,

    I’m not sure if this is how to. Contact you,
    We were going to drive up to the white river
    Marsh area. But we are not sure what there
    Is to do there. International crane foundation
    Suggested we check with you.
    Thank you
