The Aransas-Wood Buffalo population of whooping cranes nests and rears their young in Wood Buffalo National Park, Alberta/Northwest Territories, Canada, during spring and summer. After the chicks fledge, adults and juveniles migrate 2,500 miles through seven states to the U.S. Fish and Wildlife Service’s Aransas National Wildlife Refuge on the Gulf Coast of Texas where they spend the winter.

Cranes must stop 15 to 30 times to rest and feed during their migration. Radio telemetry conducted by the U.S. Geological Survey and direct field observation has documented migration stopovers that often occur in habitats associated with water resources development projects managed by the U.S. Army Corps of Engineers throughout the migration corridor.

The founder and president of the non-profit Friends of the Wild Whoopers, (FOTWW), Chester McConnell worked with Dr. Richard 
Fischer of the U.S. Army Engineer Research and Development Center; Jeremy Crossland, USACE Headquarters land uses and natural resources program manager; and Michael Champaign, USACE, Fort Worth District biologist, to develop and finalize a Memorandum of Understanding between the Corps of Engineers and FOTWW to assess whooping crane migration stopover habitat and identify measures to maintain or improve that habitat on water resources development projects in the migration corridor.

Wintering Whooping Crane Update, February 6, 2020

We completed our annual whooping crane abundance survey last week, and were able to fly three primary surveys and two secondary surveys. Areas surveyed stretch along the Texas coast from Matagorda to Port Aransas.  Phil Thorpe, pilot with the USFWS Migratory Birds program, flew the survey crew in a wheeled Kodiak again this year. In addition to an overall estimate of the winter population size, the survey provides us an estimate of how many juveniles were “recruited” into the population last summer. Better juvenile recruitment this past year in Canada (37) compared to 2018 (24) should result in a larger population this year.  For more information on our wintering abundance survey, click here.

Our secondary survey (on the edges of the core wintering range) is crucial in determining future expansion areas for a growing population. We are getting reports of whooping cranes in quite a variety of places outside our primary survey area this year, including a pair near Matagorda, Texas, three adults in Port Aransas, and marked birds in Colorado County.  A juvenile whooping crane marked last summer in Wood Buffalo National Park stopped migrating in Kansas, and is currently with a flock of sandhill cranes at Quivira National Wildlife Refuge (NWR).

Efforts to trap and mark whooping cranes here at Aransas NWR for our telemetry study is ongoing, and thus far this winter we have marked 6 whooping cranes with cellular telemetry devices. With these devices providing locations every 15 minutes, we are able to understand daily movements (night and day) and habitat use at a level that was not available even a few short years ago. You can find more about our use of this revolutionary technology to conserve whooping cranes here.

There are several opportunities for visitors to Aransas National Wildlife Refuge to view whooping cranes in publically accessible areas this winter. Whooping cranes have been consistently sighted this winter from the Heron Flats viewing deck at a much closer distance than the pair at the observation tower, providing visitors a more intimate viewing experience.  You can find a map of the refuge trails here.

Habitat Management on Aransas NWR:

Due to wet weather, we are just getting started on prescribed burning.  Our goal is to burn approximately 13,000 acres this year, the majority of which is whooping crane habitat.  So far we have completed prescribed burns totaling 1,600 acres on the Blackjack Peninsula and plan to burn at least 900 acres more this week.

Fire crews responded to a wildfire on Matagorda Island in early December.  Although this fire was unplanned, it will provide immediate and long-term benefits to whooping cranes and other wildlife. Part of the area that burned was scheduled to be burned this winter to improve habitat for whooping cranes and other wildlife. Whooping and sandhill cranes will both feed in “blackened” or freshly burned habitat and burning woody/brush species around freshwater ponds removes cover for predators. Fire also maintains coastal prairie habitat that benefits Aplomado Falcons and other prairie-dependent species.

Homer Moyers, Jr. and his wife had gone to Aransas National Wildlife Refuge in the spring for the first time to photograph the whooping cranes at the refuge. However, the morning of their trip was so foggy all of their photos were pretty disappointing. At that time they decided they had to go back in November and indeed they did return. They found out about Kevin Sim’s charter boats, Aransas Bay Birding Charters, and booked a trip on the Jack Flash.

Monday, November 25 2019, was a beautiful morning for observing and photographing all the various birds on the refuge. Homer sent us some photos taken during their outing and we have compiled them into short slideshow for your enjoyment.

Friends of the Wild Whoopers thanks Homer for sending us the fabulous photos and we are sure that you will enjoy them as much as we did.
