Whooping Cranes Survived Many Adversities

Historical Troubles

Whooping cranes have struggled to survive various adversities since man came to the North American continent. First it was the American Indians who killed them and collected their eggs for food and feathers. It is believed however that the Indians did only minor harm because their hunting equipment was primitive.                                                  Territorial Dispute Whooping Cranes at Aransas National Wildlife Refuge

Problems increased tremendously for the whoopers after the Europeans migrated to the continent. The new settlers had guns and hunted the cranes for food. But their most damaging tools were their shovels, axes and plows. These tools were used to destroy millions of acres of whooping crane habitat. Settlers drained wetlands with their shovels, cleared forest with their axes and plowed the former wetlands and forest for agricultural purposes. Yet, with all the killing and habitat destruction some of the whoopers survived. Only 14 remained in the wild in 1940 but the population slowly increased to 304 in 2014.

Disaster in Galveston Bay

Fortunately, the majority of these endangered whooping cranes have made it through some serious adversities during the past decade. The most recent hazard was the barge accident in the Houston Ship Channel that dumped tens of thousands of barrels of oil into Galveston Bay. The spilled oil followed the Gulf of Mexico currents westward down the coast and reached the Matagorda Island unit of Aransas National Wildlife Refuge. Oil killed wildlife and damaged the environment in some of the gulf waters, wetlands, estuaries and beaches, but not on Aransas Refuge.

Hundreds of oil spill cleanup workers were deployed to Matagorda Island to remove the oil due to the presents of whooping cranes and other endangered wildlife. According to the U.S. Fish and Wildlife Service, the response team worked with great care scraping thin layers of oil-drenched sand away with shovels and removed it from the beach. Aransas Refuge Manager Sonny Perez advised Friends of the Wild Whoopers (FOTWW) that “none of the oil got into the marshes or bay systems on Matagorda Island or any other part of the refuge.” However, on other areas of the Texas coast many other wild birds, turtles and porpoises were killed.

The latest information available from NOAA National Marine Fisheries Service teams reported: “21 dolphins and 4 turtles stranded. Most of these are in the Galveston, TX area but reports from Matagorda Island are increasing. All of the dolphins were dead, two turtles were captured alive and are being rehabilitated. Most of the animals were not visibly oiled but necropsies are still underway. Approximately 150 dead birds have been reported in the Galveston area and 30 in the Matagorda area.” FOTWW has asked for a final tally of dead animals.

Oil Cleanup Completed? 

Aransas Refuge Assistant Manager Felipe Prieto told FOTWW that “cleanup of oil on Matagorda Island beach is completed but we are closely monitoring to determine if more oil washes onto the beach.” Prieto also advised, “We believe all of the whooping cranes have departed Aransas National Wildlife Refuge and are currently migrating on their way to their Canadian nesting grounds. We have not observes any whoopers on the refuge in several days”.

According to Wade Harrell, U.S. Whooping Crane Recovery Coordinator, “This season we documented four whooping crane mortalities on and around Aransas NWR.”  “ FOTWW understands that except for the four documented mortalities, all of the estimated 304 whooping cranes survived the winter on Aransas Refuge. Some of the whoopers have already reached Wood Buffalo National Park in Alberta, Canada and will soon begin building their nests according John McKinnon, Wood Buffalo National Park. This is all great news for those who support the only remaining wild, self-sustaining population of whooping cranes on the planet.

Horror on the Gulf 

Whooping cranes dodged another even larger disaster known as the “BP Deepwater Horizon oil spill”.  In 2010 this horrific accident killed 11 people and spilled over four million barrels of oil into the delicate ecosystem of the Gulf of Mexico. While this disaster did not have any known effects on whooping cranes it did have catastrophic effect on other birds, fishes, porpoises, shell fish, turtles and other wildlife species.

The effect on bird populations in the area of the BP oil spill is just now being realized according to some. This week, the New York Times reported in “Still Counting Gulf Spill’s Dead Birds,” about a peer-reviewed study that estimates between 600,000 – 800,000 coastal water birds were killed in the first three months of the 2010 BP oil disaster1. According to the Times article, “This figure represents only a portion of the total bird mortality that occurred as a result of the spill. The study, which uses two different modeling techniques, is the first public estimate of a portion of bird mortality caused by the Deepwater Horizon disaster. We know that the ecosystem is deeply damaged and will take years to begin to recover.”

Fortunately, whooping cranes have not been harmed by two of the largest oil spills in the Gulf of Mexico in recent memory. FOTWW believes however that we must remain vigilant because a hurricane could possibly push some of the off shore submerged oil onto beaches and wetlands along the coast. And there is always the danger that some vessel loaded with oil or chemicals navigating along the Intracoastal Waterway could have an accident. The Intracoastal Waterway is located immediately adjacent to Aransas Refuge for about 17 miles.

Lingering Oil Worries 

Then there is the lingering worry about the abandoned and capped, but leaking oil and gas wells. According to an Associate Press news story “there are over 27,000 oil and gas wells within the Gulf of Mexico that have abandoned and have been capped to prevent the leakage of oil and gas from them. About 3,500 of these wells are oil and gas wells that have been “temporarily abandoned” and have been capped in a less stringent manner than other wells which were “permanently” capped.

Neither industry nor government checks for leaks at the oil and gas wells abandoned in the Gulf of Mexico since the late 1940s. Abandoned wells are known sometimes to fail both on land and offshore. It happens so often that a technical term has been coined for the repair job: “re-abandonment.” Collectively these wells may be allowing tremendous quantities of waste onto the gulf shores and causing harm to fish and wildlife.

Hurricane Threats 

Another major threat to whoopers and other wildlife on Aransas Refuge is hurricanes. In August of 1965 a major hurricane slammed into Matagorda Island causing significant damage. Mercifully the whooping cranes were still at Canada’s Wood Buffalo nesting grounds getting ready for their southward migration. Increasingly, however, late-summer storms are occurring and may happen when whooping cranes have arrived on Aransas.

Aransas has both a “Hurricane Plan” and an “Oil Spill Plan” according to Aransas Refuge Assistant Manager Felipe Prieto. So, the refuge officials are at well informed on what course of actions they will take in case of emergencies. Such plans can reduce damages when emergencies occur.

Fresh Water Crisis Looms

“Drought is an ongoing major adversity for Aransas Refuge. The refuge has been short on rainfall for the past three years” advised Refuge Manager Sonny Perez.

Fresh water is necessary for a healthy environment on Aransas National Wildlife Refuge.

Fresh water is necessary for a healthy environment on Aransas National Wildlife Refuge.

In fact the onset of a prolonged drought in Texas in the fall of 2008 caused serious problems for the Aransas/Wood Buffalo flock. The Aransas Refuge gets much of its fresh water from the Guadalupe River. Fresh water maintains the salinity of the coastal wetlands and allows for the production of blue crabs, the whooping crane’s major winter food. The prolonged drought and the diversions of Guadalupe River water allowed by the Texas Commission on Environmental Quality resulted in an increased salinity of water around the Aransas refuge. Tom Stehn, former U.S. Whooping Crane Coordinator contends that the salinity changes devastated the local population of blue crabs and led to the death of at least 23 whooping cranes during the winter of 2008–09.

Dr. Paul A Johnsgard, professor emeritus University of Nebraska-Lincoln wrote an in-depth article titled, “Aransas National Wildlife Refuge: The Whooping Crane’s Vulnerable Winter Retreat. He wrote: “Given the recent warming and drying climate trend in the Great Plains, and consequent increased losses of wetlands, the future of the Wood Buffalo Park–Aransas flock of whooping cranes is still by no means secure. However, without the establishment of Aransas National Wildlife Refuge at a critical time, the species would almost certainly have been added to the dismal list of twentieth-century North American bird extinctions including the passenger pigeon, Carolina parakeet, and Eskimo curlew.”

Whooping Crane Conservation topic for Audubon Meeting

Whooper adult and juvenile amazed

Friends of the Wild Whoopers member, Chester McConnell will present a program on “Whooping Cranes Conservation Efforts” at the Mobile Bay Audubon Society meeting according to Gaye Lindsey (Audubon birding coordinator). McConnell explained that his presentation will focus on management efforts for the wild whooping crane flock that migrates between Aransas Refuge in Texas and Wood Buffalo Park nesting grounds in Canada.

In addition he will discuss the two experimental flocks in the eastern U.S.   Operation Migration’s ultra-lite plane led whooping cranes fly through the entire length of Alabama on their migration path from Wisconsin to Florida. Many citizens turn out along the migration corridor to observe this most interesting effort.

Threats to the whooping crane programs including oil spills and wind energy projects will also be described.

McConnell said, “The last wild whooping cranes to be recorded in Alabama was on Dauphin Island and Prattville during November 1899 but many people continue to be interested in these beautiful  endangered birds.” Whooping cranes are the largest birds in North America and stand 5 feet tall and have wing spans of 7 feet.

Audubon’s meeting will be at Alabama’s 5 Rivers Delta Resource Center , Spanish Fort, Alabama on Tuesday, May 13 starting at 7:00 p.m. Ms. Lindsey explained that this will be an excellent presentation which is open to the public.

Louisiana Whooping Crane Eggs Did Not Hatch

May 2, 2014 – The Louisiana Department of Wildlife and Fisheries (LDWF) announced today that the first eggs produced by Louisiana’s experimental whooping crane population will not result in hatchlings this year, a result most experts had anticipated. Friends of the Wild Whoopers (FOTWW) had high hopes for the two eggs produced by Louisiana’s whoopers. FOTWW continues to believe that Louisiana may have the most favorable opportunity to reestablish a new population of whooping cranes. High Hopes for Louisiana Whooping Crane Flock.

The young pair of adult cranes, nesting in a crawfish pond on the northern end of the Cajun prairie, has been under observation by project biologists since eggs were spotted in their nest in March.  The 30-day incubation period has passed for what would have been the first whooping crane chicks hatched on the Louisiana landscape in over 75 years.  Whooping cranes are not expected to become successful nesters until they reach four to six years of age, and only a few of Louisiana’s whooping cranes will soon be four years old.  LDWF has collected the eggs and has determined they were not fertile.

Sara Zimorski, whooping crane project biologist told FOTWW that,  “Although we were hoping for viable eggs and chicks we’re still excited and proud of our birds for incubating these eggs full term and of course we have high hopes for them next spring!”

“Although this nest did not produce chicks, it is still a very positive and progressive step for the reintroduction project for many reasons,” said Robert Love, LDWF Coastal and Non-game Resources Division administrator.  “This seems to be a strongly bonded pair, which produced two normal eggs, early in the spring and incubated them full term.”

LDWF biologists collected vital data on the cranes’ nest building schedule, nest attentiveness and their reactions to nearby farming activity. Throughout the process, biologists kept the farmer and landowner informed about the cranes’ activity.

The state’s whooping crane reintroduction project began with the release of an initial cohort of juvenile cranes in 2011 at White Lake Wetlands Conservation Area in Vermilion Parish. There are three bonded pairs among the 30 surviving birds that are reaching maturity.

“From the beginning of this reintroduction, the department realized how vulnerable this species is to human harm, and knew one of the challenges would be to elevate the public’s respect for this wildlife species, through a stepwise process of awareness, appreciation and protection,” said Love. “That education and outreach challenge is being addressed through corporate sponsorship.”

The largest corporate supporter for the project is Chevron.

“Chevron believes that environmental stewardship is vital to sustainable economic progress and human development not only here in south Louisiana but throughout the world,” said Chevron Public Affairs General Manager Sakari Morrison. “The success of the whooping crane reintroduction program is encouraging for our area’s biodiversity goals but it’s also encouraging because it shows what can be accomplished through public-private partnerships. We look forward to continuing our support of the whooping cranes with LDWF.”

Team partners who assisted in bringing juvenile cranes to Louisiana annually since 2011 include the U.S. Geological Survey’s Patuxent Wildlife Research Center, the International Crane Foundation, the Louisiana Cooperative Fish and Wildlife Research Unit, and the U.S. Fish and Wildlife Service.

Wild Whooping Crane News from the Nesting Grounds…

The following is news courtesy of Wood Buffalo National Park Technician, John David McKinnon,.

“Welcome Home Whoopers!!!

Spring is here and the whooping cranes have begun to return to their nests in and around Wood Buffalo National Park.

Wood Buffalo National Park and the Canadian Wildlife Service are pleased to report the first arrivals of whooping cranes to their nesting grounds in the vast wetlands in northern WBNP. An ongoing telemetry project, a cooperative effort between CWS, Parks Canada and six US-based agencies, has allowed us to see that the cranes first arrived back on April 23rd.”

Long live the Wild Whoopers!”

Friends of the Wild Whoopers (FOTWW) talked about the migration with McKinnon. He explained that “We are always excited when the whooping cranes return to Canada from the U.S. We understand that they had a good winter at Aransas National Refuge and hope the birds will have a productive nesting season at WBNP.”

As of today only a few of the estimated 304 wild whooping cranes have completed their 2,500 mile migration to WBNP from the Texas coast. Others are expected to arrive throughout the month of May. Soon the mated pairs will return to their traditional nesting sites to construct their nest, lay two eggs and hopefully raise twin whooper chicks. Whooping cranes form pair bonds at ages 4 to 5 years and mate for life.

Friends of the Wild Whoopers wishes to thank John for this update on the first arrivals.
