  • 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.”포천출장샵포항모텔출장『카톡:miss57』{miss57.com}★2018-12-10-20-43역출장안마콜걸업소포항콜걸추천출장연애인급haC출장여대생▀포항q03콜걸후기◈g포항역출장안마외국인출장만남☜흥출장안마구리역출장안마나주출장시

    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.’계룡출장가격◎삼척출장안마야한곳«【김천콜걸추천《카톡:do26》【doo26.com】김천김천김천김천K8콜걸후기김천2018-12-10-20-43①김천흥출장안마오피걸☌김천◄◕김천출장안마야한곳】원주출장여대생➚성남오피◘용인콜걸추천┨밀양오피

    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?원주출장맛사지┬의정부출장최강미녀➸【제주도콜걸샵(카톡:up5829)『up5829.com』♟⇪✌흥출장안마▫T외국인출장만남제주도2018-12-10-20-43♧제주도콜걸후기HBe제주도▦☏v흥출장안마★출장안마】남양주출장소이스홍성✕영주출장서비스╞양주모텔출장▷구리출장서비스보장계룡릉콜걸샵{카톡:xo779}『xo779.com』콜걸e출장샵안내►R출장가격출장최강미녀gYG출장마사지sUp♪계룡↺계룡2018-12-10-20-43출장샵안내계룡F계룡♗계룡계룡

    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.부산출장아가씨속초출장마사지↭구미출장오피▌【대전출장색시미녀언니〖카톡:xo779〗〖xo779.com〗대전Ua0♧mSk대전2018-12-10-20-43대전dYl☏GPN대전대전대전대전대전출장샵대전대전▨대전◎】성남미시출장안마☣제주도출장샵후기ⓥ인천출장최강미녀£속초모텔출장

    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.안동흥출장안마¤인천출장몸매최고▣【춘천출장최고시《카톡:xo779》《xo779.com》춘천▷흥출장안마춘천d오피걸☌춘천☜출장샵콜걸☻출장마사지오피걸♐춘천출장샵강추5춘천2018-12-10-20-43】남원출장샵후기┡태백출장업소↠김천출장업소♀ 대전출장소이스홍성

    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.대전출장색시미녀언니밀양콜걸☠경산역출장안마┷【시흥출장소이스『카톡:mss41』{mss41.com}모텔출장✔시흥출장샵안내시흥2018-12-10-20-43시흥↼출장미인아가씨시흥시흥시흥Y출장샵후기♐시흥♕QwU출장업소I】군산출장마사지♧대전미시출장안마✌남원콜걸⇞평택콜걸남원출장가격(카톡:up5829)【up5829.com】남원2018-12-10-20-43╔남원남원남원aA남원콜걸출장마사지릉콜걸샵♧남원오피출장마사지남원남원출장샵후기출장색시미녀언니원주모텔출장U의정부출장미인아가씨▶【동해출장샵안내『카톡:up5829』[up5829.com]☊k동해릉콜걸샵2018-12-10-20-43동해출장업계위동해동해nbf흥출장안마mAK➽역출장안마출장미인아가씨☾♥콜걸업소출장색시미녀언니출장업계위UWl】고양콜걸만남✡밀양출장미인아가씨┃김천출장업소╩성남콜걸업소

  • And so, what we see is that the apparent efficiency of the smallest hummingbirds is down around 10 percent. If you go up to the larger hummingbirds they are — they’re up in the range of, you know, 30 percent.
