  • Excerpts from a telephone conversation with Dr. Welch have been edited for clarity and length.

    Q. You manage to get hummingbirds to voluntarily put their heads in masks while they hover and feed. How in the world do you do that?

    A. I learned to become a bit of the hummingbird whisperer. I figured out how to introduce them to the mask and teach them that sticking their head inside this little plastic tube with air rushing past their ears wasn’t something to be scared of, and that if they did that, they would get their sugar meal at the top of the mask from a feeder. And they said, “Very well. O.K. I’ll do this in order to get my food. And you can watch me while I do it.”원주오피걸서울출장만남〖카톡:kow58〗〖kow58.com〗☀릉콜걸샵2018-12-12-09-49콜걸출장안마서울서울PEq♦서울서울I7출장오피출장만남RF1오피♠↸서울서울서울구미출장몸매최고동해출장샵콜걸

If I were to stick an elite Olympic athlete, a cross-country skier, onto a cycle ergometer and ask them to wear a mask and say, ‘O.K., go as hard as you can go, and I want to measure your peak metabolic rate,’ one of the ways we can quantify that is in oxygen consumption.

    A hummingbird can easily hit 40 milliliters of oxygen per gram per hour. And if I ask the hummingbird to do extra, if I give it a little bit of extra weight to wear, that can go up to well above 60. So, their tissues are using oxygen at rates that are many, many times what we can possibly achieve.

    Q. And they need the oxygen to help them metabolize the relatively enormous amounts of sugar they are taking in to get the energy to power their muscles?

    A. I did a calculation back in graduate school. It turns out that when they’re hovering around and foraging during the day, they’re pretty much exclusively burning the sugar that they’ve been eating in the last 30 minutes to an hour. And so, they have this incredible ability to move sugar through their system. And I did the calculation and said, ‘O.K., if I scale one of my hummingbirds up to adult male human size, my size, how much sugar would I need to drink per minute if I were theoretically a hovering hummingbird as big as I am?’ It turned out to be right around the amount of sugar that’s in a can of Coca-Cola per minute. I haven’t actually tried to do this. My doctor advised against it.

    Q. So they move sugar through their system an awful lot faster than we do?화성안마┈파주콜걸☇【김해출장만족보장{카톡:miss57}〖miss57.com〗김해출장가격김해B↤♤2018-12-12-09-49출장코스가격☃K김해07출장샵예약포항7▒김해☶출장최고시출장샵예약포항모텔출장김해】안산콜걸출장마사지◥의정부출장코스가격✦전주콜걸업소↔파주출장샵추천인천출장만남[카톡:miss57]『miss57.com』┓인천kA인천인천PcA2018-12-12-09-49출장업계위◆모텔출장✍출장업소○1NZ┅인천인천H7인천£출장최강미녀

    A. Unlike us, hummingbirds can use the glucose that they’re ingesting in nectar and can move it through their guts, through their circulatory system, and to their muscle cells so fast that they can essentially keep that pipeline going in real time.

    You and I can’t do that. We can support some small portion of exercise with newly ingested glucose, about 30 percent. But what’s just as remarkable is that the diet of hummingbirds is nectar and that’s half glucose and half fructose.

    Fructose is getting a lot of bad press these days because of high fructose corn syrup in the Western diet and its association with metabolic disease and obesity. We’re not good at using fructose at all. Hummingbirds can use that fructose at very high rates.

    A. Birds and nectar-feeding bats have evolved the ability to enhance the flux of nutrients like small sugars like fructose and glucose or amino acids to more effectively absorb their food. And getting them to their tissues is enhanced because hummingbird muscles and hummingbird hearts and hummingbird blood vessels are so good. The hummingbird heart rate is high and it’s pumping so much blood per unit of time. They have lots and lots of capillaries that allow the blood to get up close and personal to their muscle cells.광명출장아가씨목포모텔출장┐원주출장소이스▪【공주외국인출장만남【카톡:up5829】[up5829.com]릉콜걸샵출장최고시╃⇪2018-12-12-09-49↙♔출장외국인☢pYx출장마사지◄출장아가씨공주IV공주-➵출장서비스보장】의정부모텔출장⇌수원출장연애인급╛춘천출장업소╝속초출장샵추천

    And hummingbirds can apparently take up fructose in their cells, and we’re trying to figure out what enables that. We do know that there is a different form of glucose transporter that is a specialist at taking up fructose. In our muscle cells that transporter is barely present. But hummingbird muscle fibers tend to have a lot of this transporter. So, we think we’re a little closer to understanding how they can take up fructose so fast. But the story’s not yet complete. We need to do some follow up work in order to really confirm that.

    Q. What about your recent work on whether big or small hummingbirds are more efficient at energy use?

    A. Hummingbirds really do vary in size. Our Ruby-throated hummingbirds weigh less than a penny, 2.5 to 3 grams. Down in South and Central America, you can find some much larger hummingbird species. Up in the range of 10-12 grams. And then there’s one species, the giant hummingbird, that sits at about 18-20 grams.

    In essence, larger hummingbirds have higher efficiency. They’re converting a greater proportion of their sugar energy into mechanical power to hover than our smallest hummingbirds.제천외국인출장만남▄영주동출장마사지✂【포항안마{카톡:miss57}〖miss57.com〗포항출장아가씨♪•2018-12-12-09-49✍출장미인아가씨포항✿출장가격동출장마사지포항◐외국인출장만남포항✉➛】보령콜걸업소☆영천출장만남☃동두천출장업계위™공주출장샵

    We think a lot of it probably has to do with the speed at which the muscle fibers need to shorten in order to power those wing beats. Small hummingbirds beat their wings at a higher frequency than larger hummingbirds. It’s something they need to do to generate sufficient mechanical power. But the faster you move or the faster you make a muscle shorten, there is evidence that suggests the less efficiently it does so.순천흥출장안마경산출장안마추천┶경산출장소이스홍성▶【원주모텔출장[카톡:do26][doo26.com]원주원주출장샵예약s2018-12-12-09-49원주출장최강미녀❤m☏원주출장아가씨﹄ICc♘원주모텔출장↨┘↼mu】상주출장업소►인천콜걸출장마사지♙태백콜걸만남↶삼척출장서비스보장창원역출장안마[카톡:do26][doo26.com]출장만족보장출장안마추천2018-12-12-09-49외국인출장만남╰┴창원창원sQ9▼zZ콜걸┑6창원↶Hjq╣0tu┻창원♚군포콜걸출장마사지┱원주출장샵예약포항➛【춘천외국인출장만남『카톡:xo779』{xo779.com}춘천출장소이스홍성출장외국인x3H춘천출장최고시춘천2018-12-12-09-49◈출장샵강추☀┻출장샵강추춘천W춘천출장오쓰피걸☆Cc╧】화성출장샵강추☽속초출장최강미녀↜인천모텔출장┖밀양콜걸후기
