  • 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.”포천출장코스가격평택출장안마야한곳[카톡:mss41]{mss41.com}↿평택2018-12-12-14-40콜걸추천평택↠미시출장안마평택╢평택평택출장미인아가씨♩↧═◊0L♖안산출장가격경주출장샵추천

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?포천출장안마추천╘계룡콜걸출장마사지⇙[나주역출장안마(카톡:xo779)『xo779.com』╂❖•출장몸매최고☭2018-12-12-14-40출장외국인bt╀출장마사지나주♘나주W☎나주나주━2나주]순천외국인출장만남➳성남출장샵추천§부천출장샵예약포항♐안동출장마사지용인흥출장안마〖카톡:xo779〗【xo779.com】용인용인용인▒29출장아가씨➶2018-12-12-14-40↗출장미인아가씨◈콜걸출장마사지↽용인출장샵예약포항출장샵용인역출장안마V

    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.광주오피걸광주콜걸추천╞목포흥출장안마♀[충주미시출장안마{카톡:xo779}[xo779.com]↫2018-12-12-14-40↰┆xBN충주충주충주⇅출장아가씨충주출장마사지출장샵예약포항6콜걸만남출장연애인급충주충주Fts출장소이스홍성]대전오피║전주콜걸만남┪전주출장미인아가씨♪광주출장안마추천

    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.속초출장시○남양주출장샵안내❈[경주출장업소【카톡:do26】『doo26.com』출장코스가격경주Vn미시출장안마♠2018-12-12-14-40⇟█↸경주미시출장안마❃n콜걸후기▫┛경주⇜➛oTd]포천출장안마야한곳↶강릉출장서비스보장╓경산외국인출장만남☻경주출장샵

    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.아산출장코스가격수원흥출장안마▐과천출장안마☼[수원출장샵콜걸{카톡:kow58}【kow58.com】수원Ql┷sO╉수원수원출장샵출장미인아가씨수원출장최고시흥출장안마AEf수원wr52018-12-12-14-40콜걸출장안마출장안마╊0ya.mS☭]사천출장샵강추▄원주출장샵강추↹김포출장업소➛청주출장마사지안양외국인출장만남{카톡:xo779}(xo779.com)출장서비스보장YM╓2018-12-12-14-40╩출장샵3K⇦R안양출장안마출장가격a출장샵콜걸Nh안양▒♜안양Weh출장샵안내안양⇁PlN양산콜걸만남┣제천오피걸⇏[의왕출장몸매최고[카톡:kow58]《kow58.com》►2018-12-12-14-40╤♡☏출장최고시콜걸출장마사지미시출장안마의왕F의왕출장샵후기n5A의왕모텔출장의왕◥의왕┩]전주출장샵✘남원출장소이스홍성⊙군산동출장마사지▀안동콜걸강추
