Parent reared Whooping Crane chick 77-18 and Sandhill Cranes in Green Lake County, Wisconsin.
Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month, migration has begun! A huge thank-you to the staff of the U.S. 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.
The current estimated population size is 102 (46 F, 53 M, 3 U). As of 1 November, around 54 Whooping Cranes are in Wisconsin, 3 in Michigan, 9 in Illinois, 13 in Indiana, 2 in Kentucky and 1 in Alabama. The remaining birds’ locations have not been confirmed in the last month or two. See map below.
As of 1 November, five wild-hatched chicks are still alive, all of which have fledged, are with their parents and are banded.
W1_18 (F) is still in Juneau Co with her parents and is now banded.
W3_18 (F) is still with her parents in Adams Co.
W5_18 (M) has migrated and is now with parents W3_10 and 8_04 in Greene Co, IN.
W6_18 (M) is still with his parents 1-04 and 16-07, but they have left Juneau Co, WI, and have not yet been seen further south.
W10_18 (U) is still with its parents 4-08 and 23-10, but they have not been seen on territory in Juneau Co, nor further south yet, but are presumably on migration or staging somewhere in Wisconsin.
16_11 (M), 73_18 (F), and 74_18 (M) are all still at Horicon NWR in Dodge Co, WI, and are doing well.
76_18 (F) was released at White River Marsh in Green Lake Co, WI, on 2 October. She moved around the area on her own for a week or so and was seen with other Whooping Cranes. Her carcass was found on 12 October in the same field 30-16 (M) and 3-17 (M) were seen. The cause of death is likely predation.
77_18 (M) was also released at White River Marsh, on 11 October. He associated with target pair 5-12 and 67-15 for a while but is now with a group of Sandhill Cranes. He is still in Green Lake Co and seems to be doing well.
