  • 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.”여수오피청주출장업소[카톡:kn887]{kn887.net}청주a청주출장샵강추청주✲출장맛사지─o출장오피♀ ◑3M콜걸샵2018-12-13-11-45☁☺N청주►╀창원출장마사지수원미시출장안마

    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.

    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?화성출장만족보장┫마산출장색시미녀언니♘【속초출장소이스[카톡:mss41]{mss41.com}속초속초출장샵강추미시출장안마출장마사지속초출장마사지속초Po오피걸출장샵강추출장안마☾HA♖출장샵강추속초출장미인아가씨2018-12-13-11-45】밀양동출장마사지┆아산출장소이스홍성┦창원오피걸◆부산출장소이스홍성대구출장코스가격『카톡:xo779』(xo779.com)안마◎┓Cn대구pUK출장서비스보장2018-12-13-11-45출장여대생콜걸만남➹외국인출장만남대구대구대구출장업계위대구nB∷출장업소c

    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.고양출장업소의정부콜걸후기✆김천출장샵콜걸✐【경주출장업소〖카톡:up5829〗《up5829.com》출장샵후기2018-12-13-11-45경주출장샵안내경주경주경주2J◇₪nm콜걸샵콜걸샵⇘☌콜걸═➼출장가격b】군산콜걸강추⇀나주출장샵예약포항▩경주콜걸출장마사지☵고양동출장마사지

    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.아산출장만남✄나주출장안마☇【경주출장오피[카톡:up5829]〖up5829.com〗▨fEH모텔출장UeU◄경주출장여대생]╉a╆♥2018-12-13-11-45경주경주z출장만족보장출장샵예약I╊경주】여수출장최고시═영주출장서비스◦의왕역출장안마○원주출장안마야한곳

    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.남원출장마사지양주출장샵강추─수원출장안마추천♨【상주출장소이스홍성(카톡:xo779)〖xo779.com〗상주d✖출장소이스zhl◣i상주2018-12-13-11-45출장업계위♟↨콜걸업소상주출장몸매최고출장샵추천✄Wa상주상주♞】논산릉콜걸샵①김해출장샵예약⇩김포출장색시미녀언니⇗속초출장시진해출장만족보장【카톡:kn887】【kn887.net】진해진해2018-12-13-11-45진해콜걸샵♝진해o✗☏출장최강미녀진해╥진해⊙콜걸출장안마진해⇁익산오피❤공주콜걸▨【전주모텔출장『카톡:kn887』[kn887.net]출장샵예약포항전주EY모텔출장콜걸출장안마NzT2018-12-13-11-45전주출장여대생♀출장여대생⇪☆➹전주♫전주┝콜걸업소h74】청주출장샵⇞순천미시출장안마☺수원출장서비스♧전주콜걸출장안마
