Future Whooping Crane Island Habitat on Canton Lake, Oklahoma

by Chester McConnell, Friends of the Wild Whoopers

Whooping Cranes are facing continuing threats to their habitats as time goes by. During their 2,500 mile migration from their Canadian nesting area to their Texas wintering habitat they must stop 15 to 30 times to rest and feed. Secure stopover habitats are needed throughout the migration corridor approximately every 25 miles. And more secure wintering habitats are needed along the Texas coast near the Aransas National Wildlife Refuge.

Dwindling wetlands

Private lands have traditionally provided most of the “stopover habitats” but many of these properties are being more intensively managed and face various forms of development. And some wetlands are becoming dryer due to global warming. So, what can we do to help? Friends of the Wild Whoopers (FOTWW) contends that lands and waters on U.S. Army Corps of Engineers (USACE) lakes, military base wetlands and Indian Reservations within the migration corridor can provide much needed relief. Many of these lands can be developed and/or managed to provide more stopover habitats for endangered Whooping Cranes. Importantly, habitats for the cranes also benefit many other species of wildlife and fish. Likewise Whooping Cranes are compatible with other wildlife…

FOTWW has completed habitat evaluations on 32 military facilities, 8 Indian Reservations and 21 USACE lakes within the wild Whooping Crane migration corridor. Some of these properties currently have suitable stopover wetland habitats while other areas could be enhanced with minor work.

USACE lakes within the 6 state migration corridor are likely to become even more important to Whooping Cranes in the near future because of their locations and quality of “stopover habitats”. Canton Lake and others that are located in the Whooping Crane migration corridor can be especially valuable.

Canton Lake, Oklahoma

Canton Lake contains 7,910 acres of surface water and 14,861 acres of public hunting land that is managed by the Oklahoma Department of Wildlife Conservation (ODWC). This area is open year round, except for the migratory bird refuge which is closed annually from 15 October to 15 February. Canton Lake’s purpose is to provide flood risk management, water supply, fish and wildlife conservation and recreation.  Since its impoundment more than 60 years ago, it has been enjoyed by millions of people. The lake offers extensive opportunity for outdoor recreation activities.

FOTWW is aware that Canton Lake, has been used by Whooping Cranes and we expect that to continue and increase. Both USACE and ODWC personnel have observed Whooping Cranes on the lake several times.

As FOTWW Wildlife Biologist, I visited Canton Lake on October 10, 2018 to assess potential “stopover habitats” for Whooping Cranes. David Hoover, Conservation Biologist, Kansas City, MO, USACE made arrangements for our trip. George Mayfield, Assistant Lake Manager and Chase Kokojan, ODWC participated in the lake stopover habitat evaluation. After discussing the natural resource objectives for Canton Lake we made a tour of the lake property by vehicle to examine the most likely places that would provide Whooping Crane “stopover habitats”. We identified several potential stopover habitat areas one of which is described below.

Canton Lake

Additional treatments may be necessary to maintain the vegetation at a height height of 2 feet or less. Whooping Cranes require areas where they can readily observe predators such as coyotes and bobcats.

If managed properly the island and shore area can become excellent “stopover habitat” for Whooping Cranes, waterfowl and other wild creatures. Vegetation in the area can be treated with herbicide and allowed to dry. After the dead vegetation is dried, it can be burned. A second treatment may be necessary to get the areas described in good condition.

DESCIPTION OF POTENTIAL “STOPOVER HABITATS”:

The photos (Figs.1 and 2 are potential “stopover habitats” for endangered Whooping Cranes to rest and roost. The island is located in an isolated location and not near frequently travel roads or power lines. The size and configuration of the wetland area varies with the levels of lake water. When the photos in this report were taken, water levels were approximately 1.5 feet higher than “normal”. Flight glide paths to the shore areas are available from different directions for approaching cranes. The shore areas and island are essentially clear of bushes and trees. Horizontal visibility from the island and shore roost sites, if properly managed, would allow Whooping Cranes to detect any predators that may be in the area. The slope of the shore and lake edge is gradual and some water depths of 2 to 10 inches would be available during “normal” lake water levels. There is little emergent or submerged vegetation in lake at these roost sites. The locations are 200 or more yards from human development or disturbance such as power lines. Hundreds of acres of foraging areas are located on ODWC wildlife food plots and in nearby agriculture fields. In addition there are wild foods in adjacent managed grasslands and wetlands that provide an abundance of insects, wild seeds and other wild food.

 

FOTWW appreciates all involved with making preparations for a productive and enjoyable visit.

Estimated Texas Wintering Whooping Crane Population Breaks 500

Estimated Texas Wintering Whooping Crane Population Breaks 500

Survey accuracy improved with shift from December to February timeframe

The first winter after Hurricane Harvey ravaged the Texas Gulf Coast, an estimated 505 whooping cranes arrived on their Texas wintering grounds after migrating 2,500 miles from their breeding grounds in Wood Buffalo National Park in Canada.  Each fall the birds make their way back to Aransas National Wildlife Refuge and surrounding habitats, where they spend the winter.  Once they have arrived, wildlife biologists with the U.S. Fish and Wildlife Service survey the birds by air and analyze population trends.

Biologists have completed analysis of aerial surveys of the Aransas-Wood Buffalo whooping crane population done last winter.  A switch in aircraft the previous winter and a shift to surveying later in the winter when a larger proportion of the population had arrived helped improve accuracy of the counts.  Preliminary data analysis indicated 505 whooping cranes, including 49 juveniles, in the primary survey area (approximately 153,950 acres) centered on Aransas National Wildlife Refuge near Austwell, Texas. An additional 21 birds were noted outside the primary survey area during the survey. This marks the 6th year in a row that the population has increased in size and the first time the population has topped the 500 mark.

“Breaking the 500 mark for this wild population is a huge milestone”, stated Amy Lueders, the Service’s Southwest Regional Director. “Seeing this iconic bird continue to expand demonstrates how the Endangered Species Act can help a species recover from the brink of extinction.  I have to credit our biologists and our partners and local communities who continue to invest so much time and effort to improve our ability to make sure future generations have the chance to marvel at the beauty of these amazing wild birds.”

The U.S. Fish and Wildlife Service has implemented several small changes that have greatly improved the agency’s capacity to survey the birds. “After two years of testing a shift of our December survey timeframe to later in the winter, we believe our previous survey estimates were likely low given that not all the whooping cranes had completed migration by mid-December. We had indications of a later than expected fall migration over the last several years via migration reports and telemetry data. This is the first year that we have based our winter abundance estimate from a February survey timeframe rather than a December timeframe. It may seem like population numbers jumped more than usual, but in reality we are just capturing a more complete proportion of the population, with most birds having completed migration by early February” stated U.S. Fish and Wildlife Service Whooping Crane Coordinator Wade Harrell.

Harrell said biologists will continue to conduct flights in late January and early February for future surveys.  He also stated that staff at Aransas National Wildlife Refuge continue to make progress in recovering from the impacts of Hurricane Harvey.  “The good news is that the coastal marsh that supports our wintering whooping cranes was not significantly damaged by the hurricane and recovered quickly from any impacts, demonstrating how resilient intact wetland habitats can be.”

Whooping cranes are one of the rarest birds in North America and are highly endangered. Cranes have been documented to live more than 30 years in the wild.   Adults generally reach reproductive age at four or five years, and then lay two eggs, usually rearing only one chick.

U.S. Army Corps of Engineers and Friends of the Wild Whoopers agree to assist in the recovery of endangered whooping cranes

Washington (July 10, 2018) – The U.S. Army Corps of Engineers (USACE) announced today the signing of a Memorandum of Understanding (MOU) with the Friends of the Wild Whoopers to assist in the recovery of endangered whooping cranes.

Per the MOU, USACE and Friends of the Wild Whoopers will jointly assess whooping crane migration stopover habitat at USACE water resources development projects. The assessments will be used by USACE to develop work plans that maintain and improve existing habitat and create additional habitat for this critically endangered bird as part of USACE Environmental Stewardship Program.

The whooping crane is one of the most endangered bird species in the world and is commonly seen as America’s symbol of conservation. Standing 5 feet tall with a wing span of 7 feet, it is the largest bird in North America.

Once fairly common, the species was reduced to just 16 birds by 1943. Market hunting and indiscriminate shooting along with habitat loss led to the decline of the species. Conservation efforts in the United States and Canada have seen the population increase to an estimated 431 birds in 2017.

This partnership is consistent with USACE’s responsibilities under the Endangered Species Act, which states that federal agencies may use their existing authorities to assist in the recovery of listed species.

Wild whooping cranes – wintering in Texas

Slideshow – Wild whooping cranes wintering in Texas

We would like to thank one of our biggest supporters and cheerleaders, Charles Hardin and his lovely wife, Jen for making and sharing this lovely slideshow with Friends of the Wild Whoopers, (FOTWW). As some of you who know Charles, he and Jen have enjoyed some great winters near Lamar and the Aransas National Wildlife Refuge while our beloved whoopers are spending their winters there. While going through some photos from past winters, Charles decided to make FOTWW a lovely slideshow to share with everyone, hoping that it brings awareness to FOTWW and the only natural remaining wild flock of whooping cranes.

We hope you enjoy Charles’ slideshow and we especially hope that you will share it with your friends and social media group members to help spread the word about the wild flock and FOTWW.

Thank you again, Charles and Jen!
