Whooping Crane Tracking Study

To learn more about the Aransas-Wood Buffalo Whooping crane population, the Whooping Crane Tracking Partnership began banding and tracking the Aransas-Wood Buffalo Whooping Crane population in 2009. The purpose for this project is to document their locations, monitor survival and their stop over locations.

Since the study began, many key areas have been identified where the Whooping cranes stop over during migration. We did not know about many of these places until this study. Now that habitat around Aransas NWR and along the flyway corridor is under development pressures, hopefully some of these key stop over areas can be purchased, conserved, and protected to ensure that there will always be habitat available for the wild ones as they migrate along the flyway corridor.

Below is a video published February 10, 2014 by Texas Parks and Wildlife showing the capture and banding of and adult whooping crane wintering at Aransas NWR.                                          – Friends of the Wild Whoopers

Aransas–Wood Buffalo Whooping Crane Telemetry Projects

The Whooping Crane Tracking Partnership began in 2008 as a research project to use Platform Transmitting Terminals with Global Positioning System capabilities (GPS-PTTs) as a means to advance knowledge of whooping crane breeding, wintering, and migratory ecology including threats to survival and population persistence and to provide reliable scientific knowledge for conservation, management, and recovery of whooping cranes.

The Partnership is comprised of the Canadian Wildlife Service, Crane Trust, Platte River Recovery Implementation Program, U.S. Fish and Wildlife Service, and U.S. Geological Survey, with support from the Gulf Coast Bird Observatory, International Crane Foundation, and Parks Canada. Partners agree the opportunity to mark wild whooping cranes with GPS technology will greatly enhance our knowledge of whooping cranes and enable us to assess risks they face during their entire life cycle. To date we have captured and attached GPS-PTTs to 31 juvenile whooping cranes at breeding sites in Wood Buffalo National Park and 24 adult and 2 juvenile whooping cranes at wintering sites at Aransas National Wildlife Refuge. Capture teams consist of individuals with experience handling endangered cranes, including a licensed veterinarian.

At capture, the veterinarian performs a health check on each crane, which includes a general external examination, blood collection for pathogen, toxin, and
genetic screening, and fecal collections for parasite evaluation. Captured birds are marked with a GPS-PTT attached with a two-piece leg band that weigh approximately 72 grams, which represents <1.5% of body weight of adult whooping cranes. The GPSPTTs have solar panels integrated on all exposed surfaces to maximize battery recharge and provide an equipment lifespan of approximately 3–5 years. Transmitters are programmed to record 4 GPS locations/day which provides us detailed information on roosting sites, diurnal use sites, and general flight paths. Transmitters upload new data on a 56-hour schedule which generally allows us to identify mortality events fairly quickly when they occur. As our sample of marked cranes is reaching peak numbers, GPS-marked cranes provided >15,000 locations during winter 2012-2013. Expectations and excitement among research partners has increased and we have begun to explore
the volume of rich information provided by marked individuals.

In addition to collecting information provided by the GPS-PTTs, the Platte River Recovery Implementation Program and researchers from the U.S. Geological Survey and Crane Trust are conducting a ground-based study spanning from northern Texas to North Dakota to evaluate habitats telemetry-marked whooping cranes have used as stopover sites during migration. The ground-based stopover site evaluations allow
researchers to collect time-sensitive data that would be difficult or impossible to measure remotely and have enabled us to learn a great deal about conditions surrounding stopover sites that may have attracted whooping cranes to the area. Where many stopovers occur on privately owned lands, these evaluations depend largely on landowners allowing researchers access to their properties and we are grateful for the
access landowners have provided us during the past several migration seasons. Upon completion of the research projects, the Platte River Recovery Implementation Program plans to use information obtained via telemetry and at stopover sites to create and manage similar habitats along the central Platte River in Nebraska.

Whooping Cranes Beginning Their Spring Journey to Canada

Media Contact: Mark Klym, 512-389-4644, mark.klym@tpwd.texas.gov

March 6, 2014

AUSTIN — Endangered whooping cranes will soon begin their annual 2,400-mile spring migration from Aransas to Canada. As the rare birds leave the Lone Star State, Texas residents and visitors are invited to report whooper sightings.

Texas Whooper Watch (http://tpwd.texas.gov/whoopingcranes/) is a volunteer monitoring program that is a part of Texas Parks and Wildlife Department’s Texas Nature Trackers program. The program was developed as a citizen science initiative to help the agency learn more about whooping cranes and their winter habitats in Texas.

Since beginning their slow recovery from a low of 16 birds in the 1940s, whoopers have wintered on the Texas coast on and near Aransas National Wildlife Refuge. Recently though, several groups of whooping cranes expanded their wintering areas to include other coastal areas and some inland sites in Central Texas. Last year, whooping cranes from an experimental flock in Louisiana spent most of their summer months in Texas, and the Whooper Watch volunteers were able to provide valuable information to TPWD, Louisiana Game and Fish and the United States Fish and Wildlife Service about these birds.

This year, biologists expect whooping cranes to start moving north in mid-March or early April. Reports to Texas Whooper Watch will also help improve the accuracy of surveys on the wintering grounds, as the growth of the flock has made traditional census methods more difficult.

Whoopers usually follow a migratory path through north and central Texas, including Wichita Falls, Fort Worth, Waco, Austin, and Victoria. During the migration they often pause overnight to use wetlands for roosting and agricultural fields for feeding, but seldom remain more than one night. The typical sighting (71 percent of all observations) is fewer than three birds, although the fall migration this year produced some groups of more than 10 birds.  They may also be seen roosting and feeding with large flocks of the smaller sandhill crane. Whoopers are the tallest birds in North America, measuring nearly five feet tall. The cranes are solid white in color except for black wing-tips that are visible only in flight, red crown and black mustache. They fly with necks and legs outstretched.

Citizens can help by reporting sightings of whooping cranes and by preventing disturbance of cranes when they remain overnight at roosting and feeding locations. Sightings can be reported to whoopingcranes@tpwd.texas.gov or (512) 389-TXWW (8999). Observers are asked especially to note whether the cranes have colored bands on their legs. Volunteers interested in attending training sessions to become “Whooper Watchers” in order to collect more detailed data may also contact  TPWD at whoopingcranes@tpwd.texas.gov or 512-389-TXWW (8999).

Additional information, including photos of whooping crane look-alike species, can be found at http://tpwd.texas.gov/whoopingcranes/ and at http://www.whoopingcrane.com/report-a-sighting/.

Whooping Cranes Love Blue Crabs

It won’t be long now and the “wild ones” will be thinking about returning to WBNP and nesting. Some of their cousins, the sandhill crane have already started their mirgration. At this time, the wild ones are still enjoying the blue crabs that, thankfully, have been plentiful this winter at ANWR.

Why are blue crabs so important to a Whooping Crane’s diet? The Whooping Cranes require blue crabs to build up their body resources and reserves for their long journey home and for successful nesting. Without a sufficient supply of blue crabs to eat during the winter, their chances of a successful nesting season and raising chicks is drastically reduced. Blue crabs are rich in protein but more importantly, the meat and shells are highly rich in calcium, necessary for strong bones and also for forming eggshells.

In the photo below, you can see a Whooping Crane foraging for blue crabs as one looks on.

Whooper History – from Gloom to Dream to Restoration

Interesting history briefs compiled by Friends of the Wild Whoopers

Recorded history of whooping cranes has ranged from beliefs that the birds would become extinct to efforts to restore the flock. Friends of the Wild Whoopers researched the literature and came across some interesting material. Some of our findings are posted here for your interest:

Gloom:   The following is from the Gutenburg Project and dated 1913.

OUR VANISHING WILD LIFE ITS EXTERMINATION AND PRESERVATION BY WILLIAM T. HORNADAY, Sc.D. Page 19. “The Whooping Crane. —This splendid bird will almost certainly be the next North American species to be totally exterminated. It is the only new world rival of the numerous large and showy cranes of the old world; for the sandhill crane is not in the same class as the white, black and blue giants of Asia. We will part from our stately Grus americanus with profound sorrow, for on this continent we ne’er shall see his like again. The well-nigh total disappearance of this species has been brought close home to us by the fact that there are less than half a dozen individuals alive in captivity, while in a wild state the bird is so rare as to be quite unobtainable. For example, for nearly five years an English [Page 19] gentlemen has been offering $1,000 for a pair, and the most enterprising bird collector in America has been quite unable to fill the order. So far as our information extends, the last living specimen captured was taken six or seven years ago. The last wild birds seen and reported were observed by Ernest Thompson Seton, who saw five below Fort McMurray, Saskatchewan, October 16th, 1907, and by John F. Ferry, who saw one at Big Quill Lake, Saskatchewan,

Photo was taken at “WHOOPING CRANES IN THE ZOOLOGICAL PARK

in June, 1909. The range of this species once covered the eastern two-thirds of the continent of North America. It extended from the Atlantic coast to the Rocky Mountains, and from Great Bear Lake to Florida and Texas. Eastward of the Mississippi it has for twenty years been totally extinct, and the last specimens taken alive were found in Kansas and Nebraska. Photo was taken at “WHOOPING CRANES IN THE ZOOLOGICAL PARK ”

Dream:    Two articles written by John O’Reilly in 1954 and 1955 issues of “Sports Illustrated” describe the extraordinary efforts of individuals, conservation organizations and government agencies to protect and manage the endangered whooping cranes. These two articles are posted below:
The surviving remnant of the great race of whooping cranes, hardly more than two dozen birds, will be “escorted” this fall from Canada to Texas. That is, they will be escorted insofar as it is possible for human beings to escort wild creatures which fly high and come to rest in lonely places. But, elusive though they may be, these huge white birds with the black wingtips will be followed on their route by thousands of well-wishers.

Here Comes The Cranes, September 20, 1954
by John O’Reilly

The Survivors of America’s tallest birds will be “escorted” south

In advance of their coming a campaign is being conducted to alert the human population along the migration route of the cranes. As was the case last fall, radio stations will broadcast appeals to report the birds but not molest them. Their trip will be announced by newspapers. Sportsmen’s clubs and civic organizations have helped spread the word. Thousands of post cards bearing the facts and a picture of a whooper have been mailed to persons living along the flight lane.
All this is part of the international effort to help America’s tallest bird in its struggle for existence.

ONLY 26 ARE LEFT
When the birds migrated last spring there were 26 whooping cranes left—in the entire population of the species. Grus americana doesn’t occur in other parts of the world and they have been studied so thoroughly that the chance of even a single bird being discovered outside this group is highly improbable.

Two of the cranes, found crippled by gunshot, are now captives in a New Orleans zoo. The rest winter on the wide marshes and prairies of the 47,000-acre Arkansas Federal Wildlife Refuge on the Texas coast, 40 miles from Corpus Christi. There they live singly and in family groups, each family occupying a territory of some 500 acres from which other cranes are driven. Without the use of a blind it is difficult to get within half a mile of them. On a trip to the refuge I jeeped and stalked the prairies for days before I got a close view of the cranes. When a pair finally flew right over me I was told that I was luckier than most.

The exact location of the nesting grounds of the remaining whoopers has not been found. This summer a scientist hovering in a helicopter over the wild country south of Canada’s Great Slave Lake looked down and spotted four whooping cranes, three adults and a young one. His find was the best evidence so far of the general location of their breeding grounds.

The whooping crane once inhabited the central part of the continent from the Arctic Coast to central Mexico. It demanded plenty of space in which to live and rear its young, and when it stood at full height to utter its challenging buglelike call, it was almost six feet tall. But as the prairies were tamed and planted, the whooping cranes dwindled steadily.

Restoration:

PROJECT FOR SALVATION
Now the Fish and Wildlife Service, the Canadian Wildlife Service and the National Audubon Society are partners in a project designed to save the whooping crane from extinction. Numerous state agencies and private groups are cooperating. One of the prime workers on the project is Robert P. Allen, research ornithologist of the National Audubon Society. Allen devoted three years to an intensive study of the cranes, hoping to find a way to halt their decline.

During that time he lived with the birds on the lonely Texas marshes in winter. In early spring he took off by plane in advance of their migration and intercepted them along the Platte River in Nebraska. He traced their migration route through Texas, Oklahoma, Kansas, Nebraska, the Dakotas and into Saskatchewan where they disappeared into Canada’s north country. He flew thousands of miles in the far north in a vain search for their nesting grounds.

People often ask how on earth the cranes know enough to go right to the refuge to spend the winter. The answer is that the presence of the whooping cranes there is historic and was one of the main reasons why the refuge was established in 1937.

As a result of Allen’s recommendations, numerous steps have been taken to aid the cranes. One of the main objectives has been to find the nesting grounds and learn whether there are any factors there which are limiting the increase. Canada has announced that when the nesting area is found it will be declared an inviolate sanctuary. Plans are now being made for a systematic search of the area next summer.

Each fall the refuge men are waiting eagerly as the cranes come back in little groups. By early December they are all in and the refuge men make an exact count by flying over them in small planes. In recent years the flock has returned with an average of four young birds. But usually a few of the parents are lost, some from being shot, and others from unknown causes. Sometimes the population fluctuates perilously. The gain or loss of a single bird is vital to the survival of the race.

Last year there was a gain. Twenty-one whoopers took off for the North in the spring and in the fall all 21 returned, bringing three gawky offspring with them. This fall more eyes than ever will be on the alert in the country’s most unusual bird-watching program.

Whoop for Cranes  –   Nov.21, 1955,   by John O’Reilly

Scientists who searched arduously and long for the nests of the all-but-extinct whooping crane rejoiced last week: its young are on the increase.  Among birds, the all-but-extinct whooping crane is most symbolic of the mighty sweep of wilderness that once was America. Tall, wary and aloof, the whooping crane demands plenty of living space. It proclaims its utter freedom with a far-reaching, buglelike call. It regards the intrusions of man with an imperious look in its cold, yellow eyes. Although but a remnant of a once-great race, Grus americana seems imbued with a special urge to survive.

These are some of the reasons why the news of the return of 20 adult whooping cranes with a bonanza of eight young has just been greeted with such national exuberance. Last spring 21 whoopers left their wintering area on the Texas coast for their breeding grounds in northern Canada. By last Monday all except one adult were back in Texas. This bird may be lost or it still may be on the way. Sometimes the last migrants don’t get back until the first week in December.

A CAUSE FOR REJOICING
The appearance of eight young birds this year is cause for rejoicing among followers of the cranes both in the United States and Canada. The eight youngsters represent the largest crop since wildlife experts first started counting the remaining cranes 17 years ago. The largest previous number was seven young in 1939.

Anxiety over the migrating whoopers mounted steadily during the past two months as they made their 2,400-mile trip. Julian Howard, manager of the 47,000-acre Aransas National Wildlife Refuge near Austwell, Texas, has been swamped with demands for information on the returning whooper families. Never has the welfare of a migrating band of birds been of such concern to so many.

During the summer, workers on Project Whooping Crane, the international effort to keep the big birds flying, discovered the long-sought nesting ground of the last of the whoopers. As a result, it was known that the cranes had hatched at least six young.

Last summer, just as interest in the whoopers was reaching its height, the United States Air Force announced plans for establishing a photoflash bombing range within a mile of part of the birds’ wintering grounds. The National Audubon Society and local Audubon societies all over the country sent protests. More protests came from the National Parks Association, the United States Fish and Wildlife Service, the National Wildlife Federation, the American Nature Association and individuals who had helped in the struggle to save the cranes. Then the Canadian government made a verbal inquiry to the State Department. Last month the Air Force announced that its proposal to establish the bombing range had been withdrawn.

Old records show that whooping cranes once nested on the great prairies of the West and ranged over most of the country. Gradually they gave way before the plow and the gun, disappearing as their nesting grounds were settled and turned into wheat lands.

As long ago as 1923 some wildlife writers had declared the whooping crane extinct. The “last” nest had been found in Saskatchewan in 1922, and the young bird was taken from it, stuffed and placed in a museum. The existence of the wintering group on the Texas coast was known only to a few and it was their presence that led to the establishment, at that spot, of the Aransas National Wildlife Refuge. The big fight to save the whoopers started when Project Whooping Crane was set up 10 years ago.

The closest human associate of the whoopers since then has been Robert P. Allen, a square-built, black-haired Pennsylvanian. As research ornithologist of the National Audubon Society and leader in Project Whooping Crane, he had studied the cranes on their wintering grounds but his attempts to find their nesting sites in the far north had been fruitless. But, as he and others continued their work, public interest increased steadily.

The cause of the whooping crane became of such widespread interest that thousands of persons were on the lookout for them. Then in June 1954 some whoopers were spotted from a plane in Canada’s Wood Buffalo National Park, a wilderness area of 17,300 square miles, most of which is never visited by anybody, tourists or otherwise.

This knowledge led the international partners in Project Whooping Crane—the Canadian Wildlife Service, the’ U.S. Fish and Wildlife Service and the National Audubon Society—to launch an all-out effort to find the nests. Their aim was to discover whether anything or anybody was molesting the birds as they reared their young.

Allen was ready to start north to lead the expedition when William A. Fuller, biologist of the Canadian Wildlife Service, became the first man to see a wild whooper’s nest since that “last” nest was reported 33 years ago. Fuller was flying in the wild country along the Sass River on May 18 with Edward Wellien and Wesley Newcomb of the U.S. Fish and Wildlife Service when he spotted a pair of whoopers and a nest. On the same flight two more nests were seen.

This news spurred the expedition to action. Next to the actual finding of the nests the most important thing was to reach the area on the ground; to learn what, if any, were the dangers to the cranes; to study their nesting habitat and collect samples of their food. Allen hurried north and was met at Fort Smith, an outpost on the Slave River, by Raymond Stewart of the Canadian Wildlife Service and Robert E. Stewart, biologist of the U.S. Fish and Wildlife Service.

Fort Smith is the jumping-off place for prospectors in the uranium rush. Men come and go and low conversations about uranium strikes are carried on in corners. So, as the three outfitted for their expedition, they were greeted with knowing smiles and sly smirks when they said they were heading into the bush to look for birds.

.

Wood Buffalo whooping crane habitat, Canada.

It was chilly on the morning of May 23 when the expedition set out down the mighty Slave River, which winds northwest to Great Slave Lake. At a great bend in the river, 44 miles from Fort Smith, they unloaded their supplies, cooked a meal and headed into the spruce forest. The Indian packers, two of them carrying the canoe, were strung out behind them. Nine hours later the three scientists said good by to the Indians and made their first camp on the shore of Long Slough.

As they moved down the slough the next morning in their overloaded canoe, the country around them was feeling the first touch of spring. Cattails were just beginning to show green. Canvasbacks, goldeneyes, buffleheads and other waterfowl were all about them. To the west they caught occasional glimpses of buffalo herds, with a spring crop of reddish-brown calves. They were still in high spirits when they made another portage, pitching their second camp on the banks of the Little Buffalo River. They moved up the Little Buffalo, still feeling fine. Turning into the Sass River, they rounded a bend to encounter their first trouble. It was a log jam, not of lumber logs but of trees and snags. They soon realized that the Sass was just one log jam after another, a fact that had not been apparent during their aerial survey.

They were sitting on the bank of the river, returning the stares of solemn buffalo and wondering what to do next, when they learned from their radio that they were believed lost and had become the objects of a search. The Northwest Mounted Police and park officials had been alerted. Unable to send out messages on their radio, they decided to strike for Fort Resolution on Great Slave Lake, where word of their safety could be sent out. After a turbulent trip down the Little Buffalo, they persuaded a Chipewyan Indian to carry a message across the frozen expanse of Great Slave Lake to Fort Resolution. Three days later Pat Carey, veteran bush pilot, dropped into the river mouth in his plane and took them back to Fort Smith. They were back where they had started.

A TRY BY HELICOPTER
Disappointment over their failure was forgotten on learning they could get the services of a helicopter which had been working north of Great Slave Lake. The helicopter transported them and their gear but, blown off course by a strong cross wind, the pilot became confused and dropped them 20 miles from where they thought they were landing. They didn’t realize this dismal fact until they had fought their way on foot for three days through swamps and sloughs.

Now they were really lost, and to make matters worse mosquitoes had emerged in millions, augmented by black flies, deer flies and a superdreadnaught called the bulldog fly. Their only relief from the clouds of insects came at night when they shut up their tent, killed the mosquitoes that were waiting inside and went to sleep.

At last, admitting they were licked, they put their canoe in the nearest river and started downstream. It turned out to be the Sass, the river of log jams. This time they cut their way through or portaged around 42 log jams, using the ax as much as the paddle. Reaching the Little Buffalo River, they went downstream and made the long portage back to the Slave River where a boat took them once more back to Fort Smith.

All told, they had been in the mosquito-infested woods for a month and hadn’t reached the home of the cranes. They had called the whole thing a failure and were ready to pull out when they learned another helicopter was available. Bob Stewart went back to Washington but Ray Stewart and Bob Allen prepared their gear for a third assault of the vast swamps.

This helicopter dropped them in the right spot and, as before, they started scouring the area on foot. Several days later Allen and Stewart emerged from a thicket to see a flash of white ahead of them. Slipping up, they came upon an adult whooping crane, drawn up to its full height of five and a half feet, silent and alert. Nearby was another. The two birds separated, finally moving out of sight. It was not until later that they learned this pair was hiding two offspring from them.

The goal had been reached. For 10 days the scientists studied the nesting habitat of the cranes. They collected specimens of frogs, fish, snails and other animal life which form the summer diet of the cranes. They also collected plant samples and made notes on everything that might have a bearing on the life of the whoopers.

Their work done, the helicopter ferried them out to the Slave River and they came up the river through the arctic twilight to Fort Smith in an outboard-driven skiff. Several days later I joined Bob Allen and Bill Fuller on a final aerial survey of the nesting area. As we moved over this watery world the scientists spotted two big, white birds. George Dannemann, our pilot, circled down to where we could tell they were whooping cranes. As the plane banked in a tight circle, we all saw not just the one, but two rusty-brown youngsters, two feet tall and standing between their white parents.

The scientists could restrain themselves no longer but began letting out whoops that would have done credit to the birds themselves. “Two young,” shouted Allen, and we all yelled in joy at just about the rarest sight that the bird world can offer in North America.
We saw two more fledglings on that flight and the scientists were jubilant. They and the thousands of others in the United States and Canada who are pulling for the whoopers know the cranes can never be brought back to their former numbers. But they also know that if Grus americana should disappear altogether it would mean the loss of something truly representative of the North American continent, for whooping cranes are nowhere else to be found.———End of O’Reilly article.

Voices from the Past:  A 1954 recording of whooping cranes at Aransas. Pam Bates explains, “The Macaulay Library has 12 different whooping crane recordings but this one was my favorite because it talks about 1954 being the first year that they had 3 young whoopers that migrated with their parents from Canada. The whooping Crane population at Aransas was 24 that winter.”

Pam Bates advises, ”The first speaker is Arthur Allen, a renowned ornithologist and who the Arthur A Allen Award is named after. Julian Howard, the second person to speak and mentions the annual count for 24 was the manager of Aransas at the time.

Present:    John O’Reilly was correct when he wrote in 1955 that “They and the thousands of others in the United States and Canada who are pulling for the whoopers know the cranes can never be brought back to their former numbers. But they also know that if Grus americana   should disappear altogether it would mean the loss of something truly representative of the North American continent, for whooping cranes are nowhere else to be found. ”

Thank goodness that some of our government agencies and private conservation organizations continued to work to restore the whooping crane flock. Very slowly during the past 60 years the flock has increased to approximately 300 in 2014. That’s progress by any measure.
