January 1, 2017, Project Update

Below is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month most Whooping Cranes have begun migration or reached their wintering areas. 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 104 (48 F, 54 M, 2 U). As of 1 January, at least 35 Whooping Cranes have been confirmed in Indiana, 3 in Illinois, 6 in Kentucky, 7 in Tennessee, 28 in Alabama, 5 in Florida, 4 in Georgia, and 1 in Louisiana. The remaining birds’ locations have not been reported during December.

Report on Whooping Crane Recovery Activities

2015 Breeding Season to 2016 Spring Migration

By Wade Harrell, Whooping Crane Recovery Coordinator, US Fish & Wildlife Service and Mark Bidwell, Whooping Crane Recovery Coordinator, Canadian Wildlife Service October 2016

 

Executive Summary
Whooping cranes are one of the most rare, highly endangered and intensively monitored bird species in North America. The Aransas-Wood Buffalo population (AWBP), which breeds in northern Canada and winters in Texas, is the only remaining wild, self-sustaining migratory population of whooping cranes. In summer 2015, surveys of the AWB detected 68 nests (May) and 23 chicks (August) resulting in an average number of chicks fledged per nest (0.34) that was lower than the 20-year long term average of 0.49 but within the long term natural range of variation. In winter 2015 (Dec) the peak population size of the AWB on the primary wintering grounds was estimated as 329 birds (95% confidence interval [CI] 293–371; CV = 0.073) and additional birds were located outside the survey area. This was a record high estimate for this whooping crane population.

 

Whooping cranes faced challenging conditions due to dry conditions and forest fires during the 2015 breeding season. Several projects were undertaken by a variety of agencies to monitor and investigate the ecology of the AWBP population, including the continuation of an initiative to mark individual birds with satellite transmitters to track their movements during the annual cycle. By the end of 2015, 11 marked birds were continuing to provide data.

 

In addition to the AWB, other populations of whooping cranes exist in Wisconsin, Florida, and Louisiana due to the efforts of many government agencies and non-governmental organizations, including the captive breeding centers where whooping cranes are reared for reintroduction. By the end of 2015 there were approximately 145 birds in reintroduced populations and 161 birds held in captivity. Nearly all of the growth in the global population of whooping cranes occurred in the wild, Aransas Wood-Buffalo population, as reintroduced populations realized minimal wild recruitment and population size was maintained via captive chick introduction.

 

Finally, in 2015, USFWS, CWS, our partners on the International Recovery Team and other organizations initiated a process to conduct a recovery planning process including an updated Population Viability Analysis (PVA) and, for the first time, a Population and Habitat Viability Assessment (PHVA). A PVA workshop was held at the Calgary Zoo in December of 2015 (see report attached). The PVA/PHVA process, led by the Conservation Breeding Specialist Group (CBSG), provides our agencies and partners with an opportunity to develop a unified vision for whooping crane management, in order to hasten recovery of the species in cost-effective and biologically appropriate ways.

October 4, 2016, Project Update

Here is the most recent update for the Eastern Migratory Population of Whooping Cranes. In the last month we have released most of this year’s cohort of parent-reared juveniles into Wisconsin. 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 109 (50 F, 57 M, 2 U). This total includes wild-hatched and released chicks from 2016. As of 4 October, at least 100 Whooping Cranes have been confirmed in WI, 1 is currently in Michigan, and 4 are in Illinois. The remaining 4 birds have not been confirmed in WI yet this year. See map below.
