Keeping an Informed Eye on America's Hooded Crane

The appearance of an Asian hooded crane in southeast Tennessee in December of 2011, came as a surprise to everyone, raising much speculation about how this individual crane came to be so far from its native habitat and whether it was actually a wild crane or a previously captive one.  Questions also arose about whether this was the same individual seen at the Platte River in April (2011), or in Idaho the previous year, or whether it was a different individual.  (More on this discussion provided in the links at the end of this post.)

Dr. Guo Yumin, of Beijing Forestry University, a chief researcher of the hooded crane and its breeding biology, advises us that we can actually come closer to distinguishing hooded crane individuals by studying the white/gray neck line of the individual, confirming similarities and differences through photographic record.

To that end, he has sent the following slide show to demonstrate how researchers have used this distinctive neck line characteristic to help identify individuals in mated pairs as they are observed on their breeding territory and while nesting in different locations from season to season.  

(Note:  Picasa has a quirky interface. When you open this blog post, the slide show may already be in progress.  The first slide is entitled:  "How to Discriminate Different Individuals of Hooded Crane." If your browser shows distortion or disorientation of slides, or if you want to see a larger view, click on the image.   This will open a separate window and take you to the Picasa website.  Click on the words "full screen" at the top left over the image to see a larger view of the slides.  In either location, you may manually move the slides forward or set the time lapse to a preferred time by using the controls at the bottom of the screen.)

Jeff and Amy Davis traveled from Pennsylvania to Tennessee to see the Hooded Crane in December while the crane was staging with sandhill cranes at the Hiwassee Wildlife Refuge from December 14th, 2011 to February 5th, 2012.

The images they captured give nice views of the Hiwassee Hooded Crane's distinctive white/gray neckline from all sides.  I say, distinctive, because the patterns are pronounced and irregular in an identifiable way.  Below, you see a front, left and back view of the crane's white/gray neck line.  Each view holds a pattern that has the potential for identification.  Any two views would allow further confirmation that you are viewing the same individual.

I suspect that the appearance of the Hooded Crane in Idaho in the spring of 2010, and subsequently, at the Platte River in April of 2011, stirred interest similar to that experienced in Tennessee.  And I would imagine there were many images taken as a result of that interest.  These images can affirm whether this Hooded Crane is the same individual that has appeared in all three locations, or whether these sightings represent more than one individual.

This comparative data would give us more information about vagrant migration and tell us whether more than one individual has wandered into North America.  It is amazing enough that this individual has found its way into the eastern United States.  It would be even more informative to be able to track its journey, backward and forward, through photographic records, affirming its identity in each location, so we can learn what it has to teach us as it travels through North America.

No matter what combination of circumstances came together to bring our rare crane visitor to the Hiwassee Wildlife Refuge this past December, the event has ambassador qualities.  Without a doubt, the crane's appearance has raised interest and awareness for the species, its survival, and the inherent value of saving our wetland ecosystems for the benefit of wildlife, and, ultimately, for ourselves.

"Cranes are ubiquitous in the earliest legends of the world's peoples, where they often figure as sentinels of heaven and omens of longevity and good fortune.  For their great beauty and imposing size--they are the largest of all flying birds on earth--they are held near-sacred in many lands.  Their broad wilderness habitat requirements make them "umbrella species"; protecting them ensures that other creatures and the earth and water of the ecosystem are also protected.  In addition, the enormous spans of cranes' migrations have encouraged international conservation efforts."   Peter Matthiessen, The Birds of Heaven:  Travels with Cranes

Where ever you find them, our world's cranes are ambassadors of peace, health and good will, for the earth, its wetlands, and for human kind.   Where cranes flourish, so also, the world around them will flourish.

What is Causing the Decline of the Hooded Crane?

A secretive bird whose breeding territories were only first discovered in 1974, the Hooded Crane is described as one of the least understood large birds in the world. And that is primarily because it nests in the remote and inaccessible sphagnum bogs scattered through the taiga in southeastern Russia, and in China, in forested wetlands in mountain valleys.

Throughout history the divergence, degradation and destruction of wetland ecosystems have threatened crane habitat around the world, including the Platte River in Nebraska, and the Guadalupe and San Antonio Rivers in Texas, USA, vital migration and wintering habitats for sandhill cranes and the world's endangered Whooping Cranes. Wetlands are often considered wastelands, areas to be modified for human consumption, development, and agriculture, despite the wetland ecosystem's important role in maintaining water quality and environmental health.

The Ussuri, Lena, and Amur Rivers of North East Asia, are fed by the boreal wetland ecosystems of the Xang'an Mountains, which remain one of the last remote wildernesses of the area.  But wetlands are being lost in China faster than any other land type, especially lands desired for agriculture.  The greatest increase in agricultural lands, through the conversion of wetlands to agricultural usage, between 1990 to 2000, occurred in the Xing'an Mountains, a primary breeding habitat for the Hooded Crane.

Dr Guo Yumin, of the Beijing Forestry University, and his team of Chinese and Russian scientists, are studying  the breeding biology of the hooded crane and teaching area communities about the value of this species.  Below, you see one of the hundreds of annual calendars distributed in local communities to educate and raise awareness about Hooded cranes and their habitat.

The chief threats to the Hooded Crane and its habitat include:  Russia and Mongolia--loss of habitat due to the construction of gold mines and reservoirs; China--illegal hunting, poisoning and reclamation of forest wetlands; Japan--over crowding of the species on wintering grounds threatening disease.

The good news is, Dr Yumin and his team, in partnership with the Whitley Fund for Nature and Grus Monacha International Aid, have been influencing change in the hooded crane's habitat through research and the education of local governments, communities, and businesses.

Successful strategies for influencing gold mining in China are now helping scientists influence relevant parties in Russia, reducing the impact of mining on the Hooded Crane's habitat. The State Forestry Bureau of China has established two Nature Reserves in Hooded Crane breeding habitat with the goal of management for the long-term as a result of Dr Yumin's team's conservation efforts. And in Japan, scientists are studying methods of decentralization for the hooded crane population on its wintering grounds and determining ways to improve habitat management.

Though much has been accomplished over the past several years, Dr Yumin affirms that hard work is yet to come. "The hooded crane still faces many threats, our protection work [has] a long way to go."

America's Hooded Crane--A Traveling Ambassador

Did you know that there are only 60 known breeding pairs of Hooded Cranes in the world?  And that the Hooded Crane's breeding and wintering habitats are threatened in at least three countries?   This post is the first in a three-part series on the endangered hooded crane and its appearance in North America.

Until recently, the Hooded Crane was not a well-know species in the United States.  But its mid-December arrival at Tennessee's Hiwassee Wildlife Refuge along with thousands of wintering sandhill cranes changed that status, giving it high visibility through state birding list-serves and the news media.  In fact, from the time it arrived at the Hiwassee Wildlife Refuge on December 14th, 2011 to its subsequent discovery in Indiana on February 8th, 2012, more than 4100 visitors came to the Hiwassee Wildlife Refuge to see this crane.  These visitors arrived from 47 states and 14 different nations.

The above numbers exclude the 3200 plus visitors that came to the Tennessee Sandhill Crane Festival held from January 14 to 15, 2012 at Birchwood, TN and the Hiwassee Wildlife Refuge.  The Hooded Crane made an appearance at the festival on Saturday, the 14th, and I was fortunate to be among the hundreds that viewed it through scopes as it foraged along the river shoreline.  Festival survey responses indicated that 12% of festival attendees came specifically to see the Hooded Crane.

That is quite a stir for a single bird, a rare bird that is smaller and darker than its sandhill crane cousins and often chased to the edges of the foraging flocks.  This is assumed to be one of the reasons it has been so visible and easy to find among thousands of staging sandhill cranes. The Hooded Crane often stays to the edges of the masses and may be seen on the outskirts of cranes in flight.

It is not certain how this individual found its way to the eastern United States, traveling now in the Mississippi and Atlantic Flyways with the migrating Eastern Population of Greater Sandhill Cranes.   Birders are watching for its arrival at staging areas north of its last seen location.  I wonder, also, if we should watch for it to the west.

Standing only 3.3 ft tall compared to the 4-5 ft sandhill cranes in the east, a  hooded crane has only twice before been recorded in the wild in North America, near Carey, Idaho, in April 2010, and at the Platte River in Nebraska in April of 2011.

The Hooded Crane is not only a rare species in the United States, it is an endangered species in its native breeding areas in China and Russia, with its numbers continuing to decline.  The hooded crane population is believed to be 9000 in number currently, but only 60 breeding pairs have been confirmed in the world.   Known breeding areas are limited to eastern Siberia in Russia and the boreal wetlands of the remote Xing'an Mountains in China, making it difficult to study its breeding behavior.  But that is just what Dr Guo Yumin and his team of Russian and Chinese scientists are doing--studying the breeding biology of hooded cranes so they can help this species and educate communities near its breeding habitat.
