A <em>rattle-squawk<\/em> reverberated from somewhere within the Douglas-firs and limber pines. A swooping <em>whoosh<\/em> of wingbeats blew through the treetops. Then the Clark\u2019s Nutcracker arrived on a bare branch. Bigger than a jay yet smaller than a crow, he wiped his miniature black lance of a bill back and forth against the branch like he had an itch.<\/p>\n<p>\u201cThat\u2019s a displacement activity,\u201d Schaming explained. \u201cHe\u2019s frustrated. He doesn\u2019t like it that the fat is on the ground.\u201d<\/p>\n<p>For weeks, the bundle of beef fat had been strung up 12 feet high. Schaming does this to habituate nutcrackers to feeding at a spot. But now the fat is down, and she\u2019s hoping her quarry doesn\u2019t notice the metal frame of a bownet trap camouflaged with leaf litter and forest duff.<\/p>\n<p>\u201cC\u2019mon down,\u201d she whispered.<\/p>\n<p>Schaming knows beef fat works best for luring nutcrackers. She\u2019s been studying this bird\u2014it\u2019s been her life\u2014since 2009 for her dissertation as a Ph.D. student at the Cornell Lab of Ornithology. She\u2019s tried peanuts, playback calls, even a dead mouse tugged by a piece of fishing line. Trial and error brought her to a fresh pile of beef trimmings from a butcher in Jackson Hole.<\/p>\n<p>Her doctoral work here in Wyoming\u2019s Bridger\u2013Teton National Forest\u2014just east of Grand Teton National Park and smack in the middle of the Greater Yellowstone Ecosystem\u2014has included 76 radio-tagged nutcrackers. It\u2019s the longest study ever conducted with individual Clark\u2019s Nutcrackers, a seven-years-and-running project that has sent Schaming deep into the backcountry for intensive research on their foraging behavior and habitat use.<\/p>\n<figure class=\"wp-block-embed legacy-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio alignright\"><div class=\"wp-block-embed__wrapper\"><iframe loading=\"lazy\" title=\"YouTube embed rZo35V03Qyk\" width=\"1200\" height=\"675\" frameborder=\"0\" allowfullscreen src=\"https:\/\/www.youtube.com\/embed\/rZo35V03Qyk?feature=oembed\"><\/iframe><\/div><figcaption>Click above to watch as Schaming sets up to trap and band a Clark&#8217;s Nutcracker. <a href=\"https:\/\/youtu.be\/ZbD9k6eKFqY\">Watch the full video\u00a0about Schaming&#8217;s research here<\/a>.<\/figcaption><\/figure>\n<p>The nutcracker swooped down to a lower branch, now tantalizingly perched just above the bait pile. Then he cocked his head to the side, reasoning and thought bubbling behind his polished obsidian pebble eyes.<\/p>\n<p>When the breeze blew just right, the curtain of fir needles behind the bird opened up to reveal a glimpse of the Grand Teton, a hulking mass of snow and rock with a band of evergreens across its midsection. The trees at the highest elevations are whitebark pines. Schaming\u2019s research could be boiled down to the nutcracker in front of her, the whitebark pines in the distance, and the tight tie that binds them.<\/p>\n<p>\u201cClark\u2019s Nutcracker is a keystone species, whitebark pine is a keystone species, and they\u2019re both in a key mutualism in this ecosystem,\u201d she says.<\/p>\n<p>Keystone species are plants or animals that are so critical to an ecosystem that the landscape would dramatically change without them. In the Greater Yellowstone Ecosystem, nutcrackers rely on whitebark pines as a crucial food source, the pines rely on nutcrackers to disperse and plant their seeds, and more than 100 other species of plants and animals benefit from that mutualism between tree and bird. But the web is at risk of unraveling. Whitebark pines have suffered massive mortalities from the deadly convergence of blister rust disease and mountain pine beetle outbreaks. Nutcracker populations have declined across half their range since 2003, according to Breeding Bird Survey data. The ripple effects extend throughout the ecosystem, from disappearing forests on mountain heights to the loss of a major food resource for grizzly bears.<\/p>\n<p>Today, Schaming is back on one of her study sites with a new technology, solar-powered satellite tags, to open up a new chapter of her research. She\u2019s searching for ways to keep the nutcracker\u2013 whitebark mutualism intact. But first, she\u2019s got to trap a bird.<\/p>\n<p>After much consternation, this noncompliant nutcracker flew away.<\/p>\n<p>\u201cHe\u2019ll be back,\u201d Schaming said confidently.<\/p>\n<div class=\"wp-block-image\">\n              <figure class=\"size-large alignnone\"><img decoding=\"async\" src=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/NutcrackerIllustration-1280x941.jpg\" srcset=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/NutcrackerIllustration-720x529.jpg 720w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/NutcrackerIllustration-768x564.jpg 768w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/NutcrackerIllustration-1280x941.jpg 1280w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/NutcrackerIllustration-480x353.jpg 480w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/NutcrackerIllustration.jpg 1600w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" alt=\"The world of the whitebark pine and the Clark\u2019s Nutcracker.

Schaming yanked the trigger string and <em>thwump<\/em>, he was caught.<\/p>\n<p>She fished him out of the net and gave him a stick to grip with his feet, much like a mother might soothe a baby with a rattle. The nutcracker didn\u2019t struggle or squawk; he seemed content. \u201cHis heart\u2019s not beating hard,\u201d she said. \u201cIt\u2019s not like chickadees where their heart is just racing.\u201d<\/p>\n<p>He did track her hand with his bill though, and when the opportunity arose, he clamped on. \u201cDoesn\u2019t hurt,\u201d Schaming noted as she checked his feathers. &#8220;Their bill is designed more to pry than pinch.\u201d<\/p>\n<p>When she flipped him over on his back the bird had two orange leg bands.

She doesn\u2019t want data on homebodies. Instead, she wants to know what happens to the travelers. In her radio-tracking studies, she has noticed that some nutcrackers tend to wander. In 2011\u2014after whitebark pines failed to produce cones\u201479 percent of the birds disappeared. \u201cI don\u2019t know if those nutcrackers flew north to Yellowstone or even Canada to find food,\u201d she said,\u201d or south to the Wind River Range, or all the way to pinyon pine forests in Arizona.\u201d<\/p>\n<p>Finding out where nutcrackers go in the event of a food collapse could be a key to managing entire landscapes to give nutcrackers what they need. And foresters are very interested in providing for nutcrackers, because they act as an unpaid crew of avian tree planters on a scale that far exceeds anything the U.S. Forest Service could afford.<\/p>\n<figure class=\"wp-block-embed legacy-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio alignright\"><div class=\"wp-block-embed__wrapper\"><iframe loading=\"lazy\" title=\"YouTube embed lvZ-JXeyK40\" width=\"1200\" height=\"675\" frameborder=\"0\" allowfullscreen src=\"https:\/\/www.youtube.com\/embed\/lvZ-JXeyK40?feature=oembed\"><\/iframe><\/div><figcaption>Click above to learn how Schaming&#8217;s work on nutcrackers is helping us understand their important connection with whitebark pine. <a href=\"https:\/\/youtu.be\/ZbD9k6eKFqY\">Watch the full video about Schaming&#8217;s research\u00a0here<\/a>.<\/figcaption><\/figure>\n<p>Scientists say that the whitebark pine is an obligate mutualist of the Clark\u2019s \u00a0Nutcracker, the tree totally reliant on the bird for seed dispersal. Whitebark \u00a0pine cones don\u2019t open on their own, and the seeds inside have no wings for \u00a0floating on the wind. Instead, the tree puts all its energy into producing a \u00a0large, fatty seed with high nutrition in the hopes that nutcrackers will come for \u00a0a feast. A nutcracker can hold up to 150 of these seeds in its sublingual pouch \u00a0(under its tongue). Nutcrackers plant the seeds at the ideal germination depth of \u00a0about an inch during caching. Each nutcracker caches up to 100,000 seeds in a \u00a0single year. But they don\u2019t retrieve all of them\u2014the untapped caches grow up into new whitebark pines.<\/p>\n<p>Along with whitebark pines, nutcrackers also disperse seeds for pinyon pines, limber pines, and 10 other conifer tree species throughout the bird\u2019s range of 11 western states and two Canadian provinces, according to forest ecologist Diana Tomback of the University of Colorado at Denver. \u201cNutcrackers play a very important role,\u201d says Tomback. \u201cThey\u2019re an architect of high-mountain forests across the West.\u201d<\/p>\n<p>Tomback was the first to document the mutualism between nutcrackers and whitebark pines in a <a href=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/10\/LB-Nutcracker-1977.pdf\">1977 <em>Living Bird<\/em> article<\/a>.\u00a0Schaming has carried Tomback\u2019s findings forward and expanded on them through more than 1,000 days in the field. On good days, she commutes past herds of grazing bison to spend a temperate summer\u2019s day in the mountains. But the work can be grueling, sometimes bushwhacking 20 miles just to locate one of her radiotagged study birds. Pepper-spray is a must in the warmer months, as she works in grizzly country and keeps vigil for long hours over a pile of beef fat. (Thankfully, she hasn\u2019t had a bear encounter yet.) Winter work means Telemark skiing through deep snow at minus-20 degrees Fahrenheit.<\/p>\n<p>Schaming\u2019s payoff has been lots of quality time spent with nutcrackers, and a slew of field observations about their caching habits. For example, she\u2019s documented that nutcrackers cache whitebark pine seeds in a variety of locations\u2014from right below the very whitebark pine tree where they harvested seeds to several miles away back in the breeding territory where they intend to nest. Some birds contribute at communal caching sites where hundreds of nutcrackers put up a massive larder, whereas others keep private stashes.<\/p>\n<p>Land managers desperately need insights into the relationship between whitebarks and nutcrackers, because the tree is experiencing a major die-off across its range, and the bird is the best hope that whitebark pine stands will still be around at the end of this century.<\/p>\n<figure class=\"wp-block-image alignfull size-large dark\">\n                  <img decoding=\"async\" src=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/DeadTreesBANNER.jpg\" alt=\"\" loading=\"lazy\">\n                  <figcaption>The twin scourges of blister rust and mountain pine beetles are devastating whitebark pines.

And then there were the gray ghosts, whitebark pine skeletons with J-shaped scrawls etched in the bare wood. Each \u201cJ\u201d marked where a mountain pine beetle female had excavated egg chambers. When the larvae in all these Js hatched, they ate the phloem and disrupted the flow of nutrients from needles to roots, thus starving the tree to death.<\/p>\n<p>The distant view was an Ansel Adams dreamscape\u2014countless snow-capped peaks amid endless rough and rugged terrain. To the north lay the Absaroka Mountains and one of the most remote federal wilderness areas in the Lower 48; to the south Togwotee Pass cut an indent before the Tetons. But Schaming knew that the scourge up here on this mountain is creeping across the land as far as her eyes could see. As of 2009, 46 percent of the whitebark stands surveyed in the Greater Yellowstone Ecosystem were classified as \u201chigh mortality\u201d; it\u2019s surely well over half by now.<\/p>\n<p>\u201cThis is one of the most beloved and pristine areas in America,\u201d she said. \u201cIt\u2019s really disturbing to climb up mountain peaks and see swaths of dead trees, and to know it\u2019s all human caused.\u201d Blister rust is a human-introduced tree disease in North America; climate change has enabled unprecedented beetle outbreaks. In some years, the temperatures stay warm enough for two hatches of pine beetles in a single year.<\/p>\n<p>The die-off could have profound ecological consequences. Whitebark pines are the foundational trees of many subalpine and treeline forests in the West. They\u2019re the first trees to regenerate after disturbance. (Tomback, the forest ecologist, saw nutcrackers caching whitebark seeds in the blackened earth after the 1988 Yellowstone fires.) As new whitebark pines sprout up, they provide shade and windbreak for other tree seedlings, such as Engelmann spruce and subalpine fir. Tomback says that as the pines and spruces and firs grow up, they cast a shade that holds onto the snowpack through the spring, preventing rapid melting and releasing the meltwater slowly through the summer.<\/p>\n<p>Besides nutcrackers, more than 100 other animal species feed on the highly nutritious whitebark pine seeds, which have a perounce calorie count about equal to butter. Other whitebark-seedeating birds include Hairy Woodpecker, Cassin\u2019s Finch, Mountain Chickadee, and Pine Grosbeak. Among mammals, grizzly bears rely on whitebark pine seeds as an important food resource. USGS biologist David Mattson has conducted research that shows mortality rates for adolescent and adult bears go up when their whitebark pine seed consumption goes down.<\/p>\n<figure class=\"wp-block-gallery alignwide columns-2 border is-cropped size-large\">\n                <ul class=\"blocks-gallery-grid\"><li class=\"blocks-gallery-item\"><figure><img decoding=\"async\" src=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/10\/BlisterRustFINAL.jpg\" srcset=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/10\/BlisterRustFINAL.jpg 528w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/10\/BlisterRustFINAL-480x457.jpg 480w\" sizes=\"\" alt=\"White pine blister rust is one of the two main factors killing whitebark pines.

In two of Schaming\u2019s first five years of field research (2008 and 2010), the whitebark cone crop failed, and she recorded no breeding activity among nutcrackers whatsoever the following spring\u2014no nesting, no trapped adults with brood patches (bare spots on their belly plumage used to incubate eggs against warm skin), and no juvenile nutcrackers spotted at all.<\/p>\n<p>Schaming posits two possibilities: either nutcrackers were in such poor body condition from a lack of nutrition that they couldn\u2019t breed, or they chose to skip the year because environmental conditions foretold lean times ahead.<\/p>\n\n<p>Whitebark pines have no such coping strategies. When a local nutcracker population declines (either due to failed breeding or because the nutcrackers abandon an area to look elsewhere for food), the tree loses its evolutionary soul mate\u2014its only agent of seed dispersal. In this scenario, whitebark pines are faced with a genetic bottleneck that eventually leads to their functional extinction in an ecosystem. That\u2019s already happened in Glacier National Park, where blister rust swept through decades ago. People in Glacier are seeing fewer nutcrackers today than they did 20 years ago, and healthy whitebark stands are virtually nonexistent.<\/p>\n<p>In recognition of the whitebark pine\u2019s ecological importance and dreadful outlook, Canada has listed the tree as an endangered species, and the United States has listed it as warranted for Endangered Species Act protection. U.S. Forest Service ecologist Robert Keane of the Rocky Mountain Research Station is a proponent of active and immediate intervention to save the tree. Keane estimates that whitebark pine forests could be functionally extinct within 100 years. \u201cWithout restoration, the whitebark pine forest is lost,\u201d he says.<\/p>\n<p><!--[gallery size=\"large\" ids=\"21079\"]\n\n--><\/p>\n<p>Restoration means active management and silviculture, such as thinning to create space for whitebark seedlings and planting the seeds of pines with blister rust-resistant genes. But that action is expensive, and the USFS budget for whitebark restoration has been shrinking year after year.<\/p>\n<p>Meanwhile, as long as nutcrackers persist, they act as agents of tree propagation that work for free. Tomback has estimated the economic value of nutcrackers at upwards of $2,500 per hectare (the equivalent cost of USFS seeding). And nutcrackers can go where people can\u2019t, planting trees in federal wilderness areas where the regulations prohibit human intervention.<\/p>\n<p>Keane\u2019s models show that nutcrackers could play a role in a whitebark renaissance. Should the pines be able to survive blister rust and beetles, a future of more frequent wildfires could offer plenty of opportunities for nutcrackers to swoop in and plant seeds in burned soil. Keane says it may actually be possible for whitebark pines to reclaim their old range and expand into new ranges in a warmer climate.<\/p>\n<p>But that only happens if nutcrackers are still around.<\/p>\n<p>\u201cWhen people think about the Greater Yellowstone, they often picture wolves and grizzly bears, these amazing charismatic megafauna [that] play really important roles as top predators,\u201d says Schaming. \u201cBut the Clark\u2019s Nutcracker, this bird that lives up high in the mountains and a lot of people don\u2019t recognize, it\u2019s a keystone species that\u2019s incredibly important in this ecosystem.\u201d<\/p>\n<figure class=\"wp-block-gallery gallery-slideshow has-nested-images featured \" style=\"\" aria-label=\"slideshow\"><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza1-1280x960.jpg\" srcset=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza1-720x540.jpg 720w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza1-768x576.jpg 768w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza1-1280x960.jpg 1280w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza1-480x360.jpg 480w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza1.jpg 1600w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" alt=\"Researcher Taza Schaming attaches a tiny backpack containing a transmitter onto a Clark's Nutcracker.\" loading=\"lazy\" \/><figcaption class=\"blocks-gallery-item__caption\">Researcher Taza Schaming attaches a tiny backpack containing a transmitter onto a Clark's Nutcracker.<\/figcaption><\/figure><figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza3-1280x960.jpg\" srcset=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza3-720x540.jpg 720w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza3-768x576.jpg 768w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza3-1280x960.jpg 1280w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza3-480x360.jpg 480w, https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/Taza3.jpg 1600w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" alt=\"All nutcrackers caught are examined.

For example, if foresters plant a whitebark pine stand somewhere, can they rely on traveling nutcrackers to find the new trees and propagate their seeds?<\/p>\n<p>She\u2019s also hoping to uncover more evidence of the importance of Douglas-firs to nutcrackers. For decades, scientists have focused solely on whitebarks or other large-seeded pines as the habitat component that nutcrackers need. But in the years of the whitebark cone crop failures, Schaming observed nutcrackers feasting on Douglas-fir seeds\u2014not a good nutritional substitute (it takes 20 Douglas-fir seeds to equal the calorie content of one whitebark pine seed), but perhaps good enough to get by in lean years. In her radio-tracking, Schaming noted that nutcrackers tended to prefer Douglas-fir habitat more often for their breeding season range than any other trees, including whitebark pine.<\/p>\n<p>\u201cMy hypothesis is that Douglas-fir seems to be a critical secondary habitat for nutcrackers in the Greater Yellowstone,\u201d says Schaming, \u201ca back-up food, hence birds choose breeding season ranges with Douglas-fir so it\u2019s available [when whitebark pine cone crops fail].\u201d<\/p>\n<p>She\u2019s submitting her research to foresters in the Bridger- Teton National Forest and nearby national parks to use in their management plans and advising them to focus their whitebark pine restoration management efforts in close proximity to Douglas- firs. It seems that both tree species are necessary to create the ideal habitat mix for nutcrackers.<\/p>\n<p>\u201cThe nutcrackers are the critical cog in the entire restoration engine,\u201d says Keane, the USFS research ecologist. \u201cCritical research such as that being done by Taza will be key to building models that predict the future nutcracker-whitebark pine dynamic and developing effective restoration treatments.\u201d<\/p>\n<figure class=\"wp-block-image alignfull size-large light\">\n                  <img decoding=\"async\" src=\"https:\/\/www.allaboutbirds.org\/news\/wp-content\/uploads\/2015\/09\/TazaTetonsBANNER.jpg\" alt=\"\" loading=\"lazy\">\n                  <figcaption>Taza Schaming&#8217;s research in Wyoming\u2019s Bridger\u2013Teton National Forest is the longest study ever conducted with individual Clark\u2019s Nutcrackers, requiring many hours deep in the backcountry for intensive research on their foraging behavior and habitat use. &lt;em&gt;Photo courtesy of Taza Schaming&lt;\/em&gt;.<\/figcaption>\n                <\/figure>\n<h4>Data revealed<\/h4>\n<p>At the Caf\u00e9 Boheme\u00a0near downtown Jackson Hole, Schaming ordered a cup of hot tea, sat down at a table, and popped open her laptop.

She learned that when the nutcrackers bounced out of the mist nets when she first tried trapping them back in 2009.
