Dr. Wade Harrell, U.S. Whooping Crane Recovery Coordinator reports that most of the Aransas/Wood Buffalo flock of whooping cranes is now on their way to their Canadian nesting grounds. The Aransas/Wood Buffalo flock is the only remaining self-supporting flock on planet earth.
Dr. Harrell advised that, “Whooping crane migration is well underway. We estimate that less than 20% of the population is still on the Texas coast wintering area and that number should quickly dwindle over the next week or so. A significant portion of the population appears to have made it across the border into Canada. Right now we have whooping cranes spread out from the wintering grounds nearly to the breeding grounds in Wood Buffalo National Park. Though the cranes seem to leave in mass, they actually have staggered departures and leave in small groups. This is important as it ensures survival of the species. If they were to all leave together and encountered bad weather or some other catastrophic event, it could put the whole population in jeopardy.”
Harrell also explained that GPS tracking of the whoopers continues. He described that “As of Sunday, April 21, four of the marked birds that we are actively receiving data on were still on the coast. Of those in migration, 12 were in Saskatchewan, eight in the Dakotas, four in Nebraska, two in Oklahoma and one in Texas. Based on this information and other observations, it is likely that more than 80% of the birds in the Aransas/Wood Buffalo population are currently migrating north.” See Wade Harrell’s full “whooping Crane Update report at: http://www.fws.gov/nwrs/threecolumn.aspx?id=2147549010
Whooping cranes are now well underway on their long 2,500 mile migration back to their nesting grounds. While some of the birds are still at Aransas National Wildlife Refuge on the Texas coast, many are working their way northward to Canada. The birds are departing Aransas Refuge in good condition due to improved habitat conditions there. Soon they will reach Wood Buffalo National Park Canada where they will build their nest and raise their young.
“Friends of the Wild Whoopers (FOTWW) received a report yesterday that four whooping cranes were spotted just outside of Regina, Saskatchewan, Canada. Regina is the capital city of the Canadian province of Saskatchewan and is a stopover spot for the AransasWood Buffalo whooping cranes before reaching Wood Buffalo National Park.
Today, FOTWW received another reported sighting from Regina along with two photographs taken this afternoon. The report read “From what we could see there were three adults and one juvenile feeding at quite a distance from the road. Due to the foreshortening of the telephoto lens, the birds appear closer to the city limits than they actually were. The field is a few miles past the city limits.”
Reports out of Aransas National Wildlife Refuge and other places along the Central Flyway have been advising for the past couple of weeks that the wild whoopers have started their migration toward their nesting grounds in Wood Buffalo. Kevin Sims was out on the water yesterday and stated to FOTWW that “We managed to find eight whoopers today. They were all very far out in the marsh. I was happy to see them it won’t be long now before they are all gone. Back to Wood Buffalo.”
During the past two weeks FOTWW has received a number of reports of whooping crane sightings near Platte River, Nebraska; Cheyenne Bottoms and Quivira Refuge, Kansas; and Aulne, Kansas.
The two photos below are proof that they are almost home.
FOTWW wishes to thank the Saskbird member for sending us the report and photos, and for Kevin who has kept everyone up to date this winter with his reports and photographs. Hopefully, we’ll have more reports and photographs, of the wild ones throughout the summer.
Whooping Cranes on their Nesting Habitat, Wood Buffalo , Canada
Have you visited Wood Buffalo National Park in northwest Canada to see whooping cranes? If so, you are among the very few. Because it is such a remote place for most people to visit, Friends of the Wild Whoopers (FOTWW) wants to share some photographs with you that provides a sample of whoopers in their natural nesting area.
Wood Buffalo National Park, located in northeastern Alberta and southern Northwest Territories, is the largest national park in Canada at 17,300 sq. mi. (44,807 km2 ). It is also the second-largest national park in the world. Importantly, it is the nesting site for the only remaining wild self-sustaining flock of whooping cranes on the planet.
FOTWW was fortunate recently to link up with John David McKinnon who shared his whooping crane album with us. John said, “It’s time to show the world the whoopers at Wood Buffalo National Park.” So that’s our goal. Be sure to check out his awesome photos and enjoy the beauty of both, the wild ones and Wood Buffalo Nation Park in John’s album: Whooping Cranes .
Thank you John for sharing, so the world can see the precious whooping cranes and Wood Buffalo National Park.
So, you believe your commute to work is a challenging ordeal? Well then, try traveling from northern Canada to the Texas coast and back every year … under your own steam. Now that’s a long, risky 2,500 miles one way — 5,000 round trip commute.
Now, imagine you are a young 4 months old whooping crane recently hatched on Wood Buffalo National Park, Canada. You are traveling with your parents on your first migration from the Wood Buffalo nesting grounds to Aransas National Wildlife Refuge on the Texas coast. It seems unbelievable but wild whooping cranes families fly this 5,000 mile round trip route every year. They fly an average 200 miles a day in all kinds of weather not knowing what dangers lie ahead, where they will spend the night or what their next meal may be. After thinking about this, your commute to work in a nice, modern vehicle should seem like a piece of cake. (See Figure 1 for migration corridor.)
Astonishingly whooping cranes are not the only birds that make long migrations. On the North America continent more than 300 bird species migrate including cranes, waterfowl and song birds. At least 40 percent of all bird species are migratory. Billions of birds migrate every year between warm winter habitats and breeding grounds, often in the far north.
Unfortunately, increasing land development by humans is causing unprecedented threats to migratory and non-migratory birds and other wildlife. This is especially true for the Aransas-Wood Buffalo population (AWBP) the only remaining wild self-sustaining flock of whooping cranes on the planet. One of the greatest needs is for more secure habitats within the migration corridor and adjacent to the Aransas Refuge. Although portions of breeding and wintering habitat frequented by the wild population are protected, those places are also geographically isolated. Habitat within the AWBP migration corridor is largely unprotected.
In 2007, the U.S. Fish and Wildlife Service published a revised Whooping Crane Recovery Plan which recommended (among other objectives) measuring and protecting stopover habitat, creating wetland habitat and managing vegetation. Some of these recommendations are being accomplished. http://www.fws.gov/refuge/Aransas/wwd/science/intl_recovery_plan.html
The migration between Aransas, Texas and the Northwest Territories of Canada spans a continent. Many dangers exist in the approximately 5,000 miles the whooping cranes must travel every year. The birds must stop daily for feeding and rest. Stop over areas need an adequate supply of freshwater and food to improve the odds of the whooper’s survival. It would be most beneficial for daily stopovers to be located approximately every 50-100 miles along the migratory corridor. Due to varying weather patterns whoopers may need to stop unexpectedly. Additionally, birds having to fly too far in a day may reduce their overall health and fitness.
Until recently, little was known about where and when some whoopers stop over. Developing a comprehensive analysis of their migratory flight patterns that identifies the most critical areas and suitable habitat ensures the cranes continue to be viable. To learn more about the AWBP, the Whooping Crane Tracking Partnership began banding and tracking birds from the population in 2009. The purpose of the project is to document whooper locations, monitor their survival and identify their stop over locations. It is essential that all interests work together to help protect and manage whooping crane habitats as well as avoid destroying or degrading already well documented crane stopover sites.
Attention needed: Friends of the Wild Whoopers (FOTWW) believes that much more attention is needed to properly protect and manage the only remaining wild self-sustaining flock of whooping cranes on the planet. This flock has served as the “Noah’s Ark” for several efforts attempting to establish additional migratory and non-migratory flocks. The only remaining repository of genetic material from the original flocks of whooping cranes is embedded within the AWBP population. Therefore FOTWW believes it is essential to provide the utmost care for this population.
Experimental projects: Several attempts have been, and are being made to establish new experimental flocks of whooping cranes. These projects are attempting to establish additional self-sustaining whooping crane populations in accordance with the International Recovery Plan for the Whooping Crane. The projects are under the guidance of the Whooping Crane Eastern Partnership. Young whoopers are initially hatched and reared in captivity and then introduced into wild habitats using several methods. One project trains young whooping cranes to migrate between wildlife refuges in Wisconsin and Florida in an Eastern Migratory Population (EMP). Some of these whoopers have begun nesting and have raised several young. The migration corridor for these EMP birds is depicted in figure 1.
Another project is attempting to start a non-migratory flock in Louisiana. These whoopers are also reared in captivity and introduced directly into the White Lake wild habitats. Conservationists are hopeful that these two projects will be successful. Until these two flocks establish themselves by reproducing and adapting to the natural environment, they are considered as experimental.
Beginning in 1993, a flock of Whooping Cranes was reintroduced in the Kissimmee Prairie in central Florida. An average of 20 chicks, hatched and reared in captivity, was released at the Florida site each year in an effort to establish a new flock of non-migratory whoopers. Some of these birds matured and began nesting. In 2002, the first whooping crane in this flock fledged. This Florida non-migratory flock is no longer receiving release captive reared whooper chick. It experienced high mortality and low reproduction. Biologists continue to monitor the remaining birds in the Florida non-migratory flock to study the problems but this project is now inactive.
Whooping cranes are an endangered species and are considered to be the symbol of conservation in North America. Whooper interests are working persistently and hoping for more successes in the conservation of these magnificent birds.
