  • 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.”보령출장샵강추경산외국인출장만남[카톡:up5829][up5829.com]출장몸매최고h출장색시미녀언니﹌출장샵콜걸2018-12-09-18-24▩①경산┳v릉콜걸샵콜걸만남출장소이스0Ab경산출장연애인급DEN경산☶경산충주출장샵후기대구출장샵예약

    A. We’re measuring oxygen consumption rates. 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. So I can say, ‘This human athlete is consuming four milliliters of oxygen per gram of body weight per hour.’양주출장외국인┑계룡출장샵강추⇈[구미출장안마《카톡:kow58》【kow58.com】☯2018-12-09-18-24출장샵예약출장샵후기콜걸업소☛n♠구미7구미구미구미구미┤♩구미구미╓]익산출장안마야한곳⊙익산콜걸후기♐공주출장소이스♔양주안마

    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?영천콜걸샵┨남양주출장안마추천[[포천콜걸만남〖카톡:kn887〗[kn887.net]£↸포천☀◥포천◆2018-12-09-18-24•포천RlK포천포천출장소이스홍성╥xj├3Hn↿포천]제천출장업소◐인천출장오쓰피걸┣동해출장여대생↺과천오피걸창원출장마사지《카톡:mss41》【mss41.com】✄창원z콜걸출장안마창원창원♕2018-12-09-18-24출장가격◦W6s창원창원H창원창원출장안마야한곳안마▄✆

    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.평택출장업소남원콜걸┰거제출장샵예약포항→[의왕출장미인아가씨〖카톡:kow58〗{kow58.com}의왕출장만족보장2018-12-09-18-24▷╯출장마사지출장아가씨콜걸┡콜걸후기●4a의왕✥의왕┌┐출장샵추천]통영동출장마사지♕거제역출장안마▨통영콜걸만남➚남양주콜걸추천

    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.부산출장안마추천.정읍콜걸-[안동안마[카톡:mss41]【mss41.com】↺OFd⇣»2018-12-09-18-24⇜안동안동╅♪⇉안동오피안동 ⇁oCK✒출장샵추천]구미출장오쓰피걸♚군산출장몸매최고♮천안출장코스가격╩경산출장샵예약

    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.하남출장서비스김천출장샵콜걸┃원주출장오피☰[군산출장시(카톡:miss57)《miss57.com》☢2018-12-09-18-24출장미인아가씨♪출장안마군산군산안마┵Z☷o군산♯s4X♂I✘군산mCe┧2군산]김제출장마사지▄논산출장안마┛고양출장마사지⇚구미오피아산출장샵[카톡:mss41]《mss41.com》♗OFd⇛⇙2018-12-09-18-24☈아산아산↬⇍☴아산흥출장안마아산☇⇙oCK♐출장색시미녀언니보령출장오쓰피걸╄경주흥출장안마═[군산오피걸【카톡:xo779】《xo779.com》군산군산G✔MNX2018-12-09-18-24⇩╭↔군산↼Da군산J출장만족보장«┎콜걸만남sZY출장샵예약☂출장서비스보장]남원출장샵콜걸♜화성동출장마사지◑구미출장코스가격✖경주출장업계위
