Understanding how they learn from us could help us train them better,” says Buchsbaum.</p> <p>“The dog wants to listen and learn, but it doesn’t understand that it’s being taught. They are paying attention, it’s just that their interpretation is maybe not the same as what you are trying to communicate.”</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__3732 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/Pumpkin%20with%20Daphna%2C%20Aarushi%2C%20Julia%2C%20Madeline.jpg" style="width: 750px; height: 498px;" typeof="foaf:Image"><br> <em>From left to right, Assistant Professor Daphna Buchsbaum, and&nbsp;undergraduate student Aarushi Gupta,&nbsp;graduate student Julia Espinosa,&nbsp;undergraduate student Madeline Pelgrim,&nbsp;and Buchsbaum's dog Pumpkin, a senior Labrador Retriever mix (photo by&nbsp;Diana Tyszko)</em></p> <p>The researchers found that even using teaching cues they thought would be helpful, such as saying “hey look” to a dog just before a demonstration, actually distracted them into maintaining eye contact rather than watching what the person was doing.</p> <p>“Everything we’re discovering is either confirming a result for the very first time or doing something nobody has ever really looked at before,” says <strong>Madeline Pelgrim</strong>, a second-year student majoring in psychology and human biology.</p> <p>“Our research and our findings are going to influence the future of the field, and 10 years down the line, people will be looking at the research we’re doing now and wondering what they can do to build on that.”</p> <p>Researchers have long argued about whether the ability to discern what&nbsp;they are being taught is innate to humans and other animals. There is little evidence that animals in the wild, for example, are “taught” by their parents: they simply learn through observation, and trial and error.</p> <p>But their long association with their human companions have made dogs uniquely sensitive to cues thought to be associated with teaching, such as sharing, pointing and directing their attention to certain actions.</p> <p>The researchers had high hopes this would make dogs one of the few animal species that – like young children – are aware of when they are being “taught” something. The study, however, seems to suggest otherwise.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__3733 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/Pumpkin%202%20with%20Madeline%2C%20Daphna%2C%20Julia.jpg" style="width: 750px; height: 498px;" typeof="foaf:Image"><br> <em>Daphna Buchsbaum observes an experiment conducted by Julia Espinosa (right) and Madeline Pelgrim (left) (photo by&nbsp;Diana Tyszko)</em></p> <p>The dogs were shown a sequence of events – such as spinning a dial and then pushing a button – that would produce a treat from a box. The dogs tended to copy the second action they saw and ignore the first, especially when they figured out the box would still produce a treat if they just followed one action instead of both.</p> <p>This experiment showed the dogs were not interpreting the demonstration they were being shown as a “teaching” moment in the same way that a child does.&nbsp;</p> <p>“It shows selectivity in their copying, whereas a three- to five-year-old child would copy both actions exactly,” says Tecwyn.</p> <p>A second study is exploring if dogs – unlike infant children and monkeys – can locate an object that is dropped but does not fall straight down because it is directed somewhere else by a barrier, like a shelf or a curved tube.</p> <p>Gravity bias makes children and monkeys look for the object on the ground directly beneath where it was dropped.</p> <p>“Dogs do not appear to have this gravity bias,” says Tecwyn. “They learn how to solve the task.”</p> <p>The program enables researchers to involve undergraduate students in ongoing projects with multiple experiments,&nbsp;says Buchsbaum.</p> <p>Many of the experiments require at least three people in the lab to assist, and the undergraduates have been&nbsp;an invaluable part of the process. They not only help with collecting data&nbsp;but also with every other aspect of the experiments&nbsp;from recruiting the subjects&nbsp;to reviewing the literature and verifying the results.</p> <p>“We need them for every aspect of this work,” says Buchsbaum. “It literally wouldn’t be possible to run the studies without them.”</p> <p><strong>Aarushi Gupta</strong>, a second-year human biology and physiology major, says she was nervous when she first started the research opportunity program, but gained confidence over time.<br> “It’s cool and exciting to be part of original research that is going to be published.”&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 08 Mar 2017 19:30:30 +0000 ullahnor 105515 at Monkeys play the odds, say U of T researchers /news/monkeys-play-odds-say-u-t-researchers <span class="field field--name-title field--type-string field--label-hidden">Monkeys play the odds, say U of T researchers </span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2017-01-10-capuchin-monkey.jpg?h=afdc3185&amp;itok=tUR5G5QO 370w, /sites/default/files/styles/news_banner_740/public/2017-01-10-capuchin-monkey.jpg?h=afdc3185&amp;itok=XiJMFGxZ 740w, /sites/default/files/styles/news_banner_1110/public/2017-01-10-capuchin-monkey.jpg?h=afdc3185&amp;itok=w7JADBGw 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2017-01-10-capuchin-monkey.jpg?h=afdc3185&amp;itok=tUR5G5QO" alt="Photo of capuchin monkeys"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>ullahnor</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2017-01-10T15:06:02-05:00" title="Tuesday, January 10, 2017 - 15:06" class="datetime">Tue, 01/10/2017 - 15:06</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">Assistant Professor of Psychology Daphna Buchsbaum: “It might be that they are not that very different from us at all” (photos by Emma Tecwyn)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/peter-boisseau" hreflang="en">Peter Boisseau</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Peter Boisseau</div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/global-lens" hreflang="en">Global Lens</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/monkeys" hreflang="en">Monkeys</a></div> <div class="field__item"><a href="/news/tags/animal" hreflang="en">Animal</a></div> <div class="field__item"><a href="/news/tags/psychology" hreflang="en">Psychology</a></div> <div class="field__item"><a href="/news/tags/primate" hreflang="en">Primate</a></div> </div> <div class="field field--name-field-subheadline field--type-string-long field--label-above"> <div class="field__label">Subheadline</div> <div class="field__item">A study on statistical reasoning among capuchin monkeys finds the first evidence that a monkey species is capable of making decisions on the basis of probabilities</div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>It wasn’t exactly a Planet of the Apes moment, but when two Ƶ&nbsp;researchers recently proved monkeys can reason about proportions and ratios, it opened a world of possibilities to tickle the fancy of even a Hollywood scriptwriter.&nbsp;</p> <p>The study on statistical reasoning among capuchin monkeys by <strong>Daphna Buchsbaum</strong>, an assistant professor of psychology,&nbsp;and <strong>Emma Tecwyn</strong>, a postdoctoral researcher,&nbsp;is the first evidence a monkey species is capable of making decisions on the basis of probabilities.</p> <p>The Faculty of Arts &amp; Science researchers' study, published online in <a href="http://link.springer.com/article/10.1007%2Fs10071-016-1043-9"><em>Animal Cognition</em></a>, tested the monkeys using jars of desirable peanuts and undesirable pellets in different ratios to prove they can reason about relative amounts, as opposed to just making straightforward comparisons about quantities.&nbsp;The 19 monkeys who participated in the study are from the ‘Living Links to Human Evolution’ Research Centre at the Royal Zoological Society of Scotland, Edinburgh Zoo, UK.</p> <p>The study also demonstrated that the monkeys – like great apes – &nbsp;share a capability once thought to be uniquely human.</p> <p>“It might be that they are not that very different from us at all,” says Buchsbaum, adding that in a sense, the results also further our understanding of ourselves as humans.</p> <p>While it still leaves capuchin monkeys a long way from the talking hero apes of the popular movie series, the type of intuitive ability they demonstrated in the lab tests is a building block for complex thinking, such as understanding cause and effect, and language.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__3096 img__view_mode__media_original attr__format__media_original" height="563" src="/sites/default/files/Capuchin_4.jpg" typeof="foaf:Image" width="750" loading="lazy"></p> <p>The researchers say infants use the same ability to understand other people’s goals and preferences.</p> <p>“I think the fact that monkeys do share this ability would make us potentially more optimistic that they might also be capable of more sophisticated social inferences,” says&nbsp;Buchsbaum. “While monkeys are unlikely to be capable of learning language, the ability to track probabilities is absolutely related to language learning.”</p> <p>The statistical reasoning abilities shared by human infants and monkeys are part of a broader range of cognitive skills that encompass everything from predicting the behaviour of others to being able to reason about someone’s desires and mental state.</p> <p>Buchsbaum notes there are more immediate applications for this ability in monkeys such as how to forage and compete for food successfully.</p> <p>For now, the scientists are satisfied to add to their growing knowledge about the evolutionary traits of humans and other animals, particularly primates.</p> <p>Until recently, the ability to make inferences using probabilities was thought to develop relatively late in childhood. But recent work revealed this ability in infants as young as 10 months old to a one year old.</p> <p>Other research suggests that great apes such as chimpanzees, gorillas and orangutans also share this intuitive statistical ability with human infants.</p> <p>What’s intriguing about the monkey study is it suggests that this ability developed earlier on the ancestral tree&nbsp;before apes and&nbsp;humans&nbsp;branched off, Tecwyn says.</p> <p>Humans shared a common ancestor with chimps about six million years ago. But we last shared a common ancestor with capuchin monkeys about 30 million years ago.</p> <p>“So we could make the inference that this ability is at least that ancient,” Tecwyn says.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__3097 img__view_mode__media_original attr__format__media_original" height="563" src="/sites/default/files/Capuchin_5.jpg" typeof="foaf:Image" width="750" loading="lazy"></p> <p>It is possible&nbsp;but unlikely, that statistical reasoning is a trait capuchins evolved independently, and it is not shared by other monkey species, adds Buchsbaum.</p> <p>“Given that humans, apes and capuchins all share the trait, it is more likely that it evolved once earlier rather than independently in these different groups.”</p> <p>Researchers have long been on a quest to establish what makes humans unique from other animals&nbsp;and conversely, what cognitive abilities are shared. Like the ape studies before it, the capuchin research further lays to rest the idea that probabilistic reasoning is one of the traits that makes humans unique.</p> <p>Buchsbaum says an exciting avenue for future research would be investigating whether animals other than primates also share this ability to make intuitive statistical inferences, and whether non-human animals are capable of more sophisticated social reasoning often thought to be unique to humans.</p> <p>“But regardless, within the broader animal kingdom, I don’t think we can doubt monkeys are pretty sensitive and intelligent animals,”&nbsp;Buchsbaum says.</p> <p>Other collaborators on the research –&nbsp;conducted at the <a href="http://www.living-links.org/">Living Links research centre</a> at the Edinburgh Zoo –&nbsp;are <a href="https://uwaterloo.ca/psychology/people-profiles/stephanie-denison">Stephanie Denison</a> of the University of Waterloo and <a href="https://www.hw.ac.uk/schools/social-sciences/staff-directory/emily-messer.htm">Emily Messer</a> of Heriot Watt University, Edinburgh.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Tue, 10 Jan 2017 20:06:02 +0000 ullahnor 103252 at The complicated history of zoos: U of T's Dan Bender /news/complicated-history-zoos-u-t-s-dan-bender <span class="field field--name-title field--type-string field--label-hidden">The complicated history of zoos: U of T's Dan Bender</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2016-11-16-zoo-lead.jpg?h=fab47044&amp;itok=49H9PB5d 370w, /sites/default/files/styles/news_banner_740/public/2016-11-16-zoo-lead.jpg?h=fab47044&amp;itok=PukNYSHj 740w, /sites/default/files/styles/news_banner_1110/public/2016-11-16-zoo-lead.jpg?h=fab47044&amp;itok=oW1J-SCa 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2016-11-16-zoo-lead.jpg?h=fab47044&amp;itok=49H9PB5d" alt="Photo of seal at a zoo"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>ullahnor</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2016-11-16T16:56:13-05:00" title="Wednesday, November 16, 2016 - 16:56" class="datetime">Wed, 11/16/2016 - 16:56</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">U of T Scarborough history professor Dan Bender talks about the controversial history of zoos in his new book (photo by Bradley Anderson via Flickr)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/don-campbell" hreflang="en">Don Campbell</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Don Campbell</div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/city-culture" hreflang="en">City &amp;

height: 200px; margin: 10px; float: left;" typeof="foaf:Image">In his new book<em> The Animal Game</em>, U of T Scarborough history professor <strong>Dan Bender</strong> dives into this irony, exploring the uncomfortable aspects of zoo history while also illustrating their rise as important centres for conserving animals that are quickly disappearing in the wild. &nbsp;</p> <p>“The history of zoos can be troubling, and the zoos of the past are certainly very different than those of today,” says Bender, who teaches a course on animal history.&nbsp;</p> <p>“But we need to make sense of why zoos are such important cultural institutions that continue to define our popular understanding of different parts of the world.”</p> <p>Bender’s book focuses on the period from the 1870s when zoos were first being established to their evolution as places for animal conservation and breeding beginning in the 1970s. It’s a history that coincides with the rise of American imperial power whose elites were competing with their contemporaries in Europe to build the biggest and best cultural institutions. Those elites envisioned zoos as orderly places of education, where the public could go to learn about animals.&nbsp;</p> <p>“Early zoos were organized in opposition to the little menageries of circuses and the world of P.T. Barnum, but it didn’t work,” says Bender.&nbsp;</p> <p>“Zoo visitors didn’t follow the signs. They wanted to poke and feed the animals. Zoos were meant to be science labs for study, yet all people wanted to do was ride the animals.”&nbsp;</p> <p>Bender uses sources including archival documents, artifacts, books, films, memoirs and other materials such as souvenir postcards, maps and magazines to bring the history of zoos to life. But it wasn’t always easy gaining access to zoo archives.&nbsp;</p> <p>“Some zoos were great. Others outright told me I would never get to see their archives,” he says. “It became a challenge to get into these archives and shed a light on a history many were intent on keeping in the closet.”&nbsp;</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2547 img__view_mode__media_original attr__format__media_original" height="493" src="/sites/default/files/2016-11-16-Zoo_Parade-embed.jpg" typeof="foaf:Image" width="750" loading="lazy"><br> <em>The U of T Scarborough library has digitized parts of&nbsp;Marlin&nbsp;Perkins' Zoo Parade Board game</em></p> <p>It’s impossible to talk about the history of zoos without looking at the wild animal trade, notes Bender. He recalls Frank Buck, an American icon during his time, but someone who would be judged as appalling by modern standards. Buck was heavily involved in the animal trade and created a celebrity persona around capturing animals in the wild. In reality, notes Bender, he was buying animals from markets in Singapore and shipping them to America. &nbsp;</p> <p>“As he was doing this he also spun these imagined tales and created this image of animal capturers as brave men.”</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2549 img__view_mode__media_original attr__format__media_original" src="/sites/default/files/2016-11-16-Zoo_Parade-1_0.jpg" style="width: 150px; height: 657px; float: right; margin: 10px;" typeof="foaf:Image">Buck’s movies were very popular during the interwar period and heavily influenced western perceptions of jungles as wild, untamed places filled with “savage” people&nbsp;and dangerous animals. They also contained “horrific” animal fights that were staged for the camera.</p> <p>Many of the artifacts collected for the book have been <a href="http://digitalscholarship.utsc.utoronto.ca/projects/islandora/object/animalempire:root">digitized by the U of T Scarborough library</a>. One of these is the Marlin Perkins' Zoo Parade board game, which involves capturing animals in the wild and shipping them to America. The game has also been <a href="http://digitalscholarship.utsc.utoronto.ca/ZooParade/">programmed to play online</a> and also features interactive photos highlighting important events in zoo history.</p> <p>Bender notes that during the Cold War period, popular culture turned its attention towards the nuclear family of the 1950s. The wild animal trade was slowly being outlawed, thus zoos began looking more into their breeding programs. This not only maintained their stock of animals, it also attracted visitors eager to see baby monkeys, lions and elephants. &nbsp;</p> <p>While the debate over the true place of zoos continues –&nbsp;dominated by animal rights advocates on one side and by those committed to the conservation of wild animals on the other –&nbsp;there’s no denying the importance zoos play in shaping popular attitudes towards animals.</p> <p>Bender points to the popularity of chimpanzee shows of the early 20th century as a prime example. These vaudeville shows with often racist aspects were adopted by zoos and became big money makers. By the 1980s most accredited zoos across the U.S. had all but decided to put an end to them, not because the public didn’t want them, but because zoos no longer wanted to display their animals that way.&nbsp;</p> <p>“The aim of the book is to shed a light on the uncomfortable aspects of zoo history while also recognizing their enduring place as important cultural institutions,” he says. &nbsp;&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Wed, 16 Nov 2016 21:56:13 +0000 ullahnor 102430 at Why some hummingbirds balloon up before they fly south: U of T research /news/why-some-hummingbirds-balloon-they-fly-south-u-t-research <span class="field field--name-title field--type-string field--label-hidden">Why some hummingbirds balloon up before they fly south: U of T research</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2016-10-13-hummingbird-lead_0.jpg?h=afdc3185&amp;itok=VrOrQFCh 370w, /sites/default/files/styles/news_banner_740/public/2016-10-13-hummingbird-lead_0.jpg?h=afdc3185&amp;itok=M6Ho50LB 740w, /sites/default/files/styles/news_banner_1110/public/2016-10-13-hummingbird-lead_0.jpg?h=afdc3185&amp;itok=j4Zq4NRq 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2016-10-13-hummingbird-lead_0.jpg?h=afdc3185&amp;itok=VrOrQFCh" alt="Photo of hummingbird"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>ullahnor</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2016-10-13T14:14:29-04:00" title="Thursday, October 13, 2016 - 14:14" class="datetime">Thu, 10/13/2016 - 14:14</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item">A ruby-throated hummingbird (Photo by Ken Jones)</div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/don-campbell" hreflang="en">Don Campbell</a></div> </div> <div class="field field--name-field-author-legacy field--type-string field--label-above"> <div class="field__label">Author legacy</div> <div class="field__item">Don Campbell</div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/biology" hreflang="en">Biology</a></div> <div class="field__item"><a href="/news/tags/u-t-scarborough" hreflang="en">U of T Scarborough</a></div> <div class="field__item"><a href="/news/tags/utsc" hreflang="en">UTSC</a></div> <div class="field__item"><a href="/news/tags/research" hreflang="en">Research</a></div> <div class="field__item"><a href="/news/tags/animal" hreflang="en">Animal</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Some adult ruby-throated hummingbirds choose to pack on significant weight in the four days before their long migratory flights south for the winter, a new U of T study has found.&nbsp;</p> <p>“Many different birds fatten up before they migrate, but we wanted to know what specific strategies hummingbirds use to fuel up prior to migration,” says <strong>Ken Welch</strong>, an associate professor of biological sciences at U of T Scarborough.&nbsp;</p> <p>“It turns out that individual hummingbirds make individual decisions – some fatten up for long flights, while others stop and fuel along the way.”&nbsp;</p> <p>Welch and master's student <strong>Lily Hou</strong> developed a unique system to track and weigh hummingbirds in the wild before migration using radio frequency identification tags. Every&nbsp;bird had a microchip and was weighed each time it&nbsp;landed on a balance attached to the feeder. &nbsp;</p> <p>Hummingbirds that fatten up spent more time at feeders in order to gain weight rapidly, the researchers found –&nbsp;in some cases putting on as much as 35 to 40 per cent of their body mass in the four days before migration. They also found that no juvenile birds were fattening, meaning that those choosing to spend more time at feeders&nbsp;had made the migratory trip at least once.&nbsp;</p> <p>“This suggests fattening could be a learned behaviour,” says Welch.</p> <p>The findings add to a growing body of research that suggests&nbsp;pre-migration strategies for some birds&nbsp;are affected by age and experience, he says.&nbsp;</p> <p>&nbsp;</p> <p><iframe allowfullscreen frameborder="0" height="315" src="https://www.youtube.com/embed/Lfias345XpU" width="560"></iframe></p> <p>Birds generally use two strategies when it comes to preparing for migration. One prioritizes fattening to allow a more direct flight in order to arrive at the wintering grounds quickly. The other involves shorter flights, stopping and feeding along the way.&nbsp;</p> <p>There are advantages to both, notes Welch. Short trips can be a safe strategy as long as resources can be found reliably along the way, but it can take longer to arrive at the final destination. For other birds, fattening may be necessary to take longer flights over large ecological barriers like oceans or deserts.&nbsp;</p> <p>“The reason some hummingbirds fatten up before their long flight may be to gain an advantage over potential rivals – by arriving at their wintering grounds in southern Mexico and Central America quickly they can establish territories and control the best resources,” he says.</p> <p><img alt class="media-image attr__typeof__foaf:Image img__fid__2234 img__view_mode__media_original attr__format__media_original" height="497" src="/sites/default/files/hummingbird3-embed.jpg" typeof="foaf:Image" width="750" loading="lazy"><br> <em>(hummingbird approaching a feeder, photo by Ken Welch)</em></p> <p>During breeding season, hummingbirds generally only increase their eating activity in the evening before fasting for the night, while reducing it in the middle of the day. But the hummingbirds that fatten for migration tended to increase their eating activity during midday and the early evening.</p> <h3><a href="/news/international-team-led-u-t-ken-welch-receives-16-million-hummingbird-research">Read more about Welch</a><a href="/news/international-team-led-u-t-ken-welch-receives-16-million-hummingbird-research">’</a><a href="/news/international-team-led-u-t-ken-welch-receives-16-million-hummingbird-research">s research</a></h3> <p>Welch’s past research found that hummingbirds can fuel their highly energetic hovering flight by burning both glucose and fructose, but he says it’s important to remember these are migratory birds and that carbohydrates alone are not enough.&nbsp;</p> <p>“Migration is powered by fat. It’s extraordinary that hummingbirds can burn sugar to sustain their high metabolic rate, but it’s also amazing to think they can switch and do the same thing using just fat,” he says.</p> <p>“The ability to switch between these fuels and to take sugar in, to build fat rapidly, underlines how flexible their metabolism is in addition to being supercharged.”&nbsp;</p> <p>The study, which received funding from the National Geographic Society and the Natural Sciences and Engineering Research Council (NSERC), is available online in the journal<em> <a href="http://www.journals.elsevier.com/animal-behaviour">Animal Behaviour</a></em>.&nbsp;</p> <h3><a href="/news/hummingbird-diet-maximum-sugar-minimum-weight-gain">Read more about the hummingbird diet</a></h3> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 13 Oct 2016 18:14:29 +0000 ullahnor 101420 at
