How Long Can Andean Condors Fly Without Flapping Their Wings
Imagine your average three-year-old human child something around three feet or a meter tall probably covered in jam a now imagine that child trying to get off the ground with a pair of wings bid have to be pretty big wings. Welcome to the plight of the Indian condor species name Volt Hor griffiths the heaviest flying bird in the world. Weighing in at up to thirty three pounds or fifteen kilos, they keep their heavy bodies in the air with some of the longest wings in the world there wingspan can range over ten feet long that's over three meters. There are only a handful of birds carnally living on our planet have larger wings spans, and they're all pelagics, birds, a plastic birds being seabirds that soar over the open ocean for weeks at a time, such as fast petrels and sheer waters. As far as we know, the largest brand ever fly was the Pella. Gorna Sanders C., which lived twenty five to twenty, eight million years ago and was twice as large as the biggest bird living today with a wingspan of twenty four feet over seven meters. Seabirds can accomplish this. Thanks in part to the literally uplifting winds that flow over oceans the Indian condor. Mostly relies on updrafts high in the Andes mountains across much of Western, south. America. The problem with being such a huge bird is that it makes getting off the ground or even flapping those giant wings and flight a bit of an ordeal. Soaring is easy once they're up in the sky and that's mainly what Andean condors do they just float like hang gliders in the air currents sometimes serving the ground for dead animals to eat as a scavenger and sometimes just having an APP. But this means that taking off is the most costly part of the birds overall energy supply. Scientists have always known that they spend very little time flapping their wings but a study published in July of twenty. Twenty and the proceedings of the National Academy of Sciences found the Andean condors flap, their wings, a sum total of almost never. Not, only to the researchers find colossal birds, flap their wings one percent of their total flight time they discovered a bird could fly for five hours and more than one hundred miles or one hundred, fifty kilometers without flapping them once. The research team found that weather didn't affect how much flapping the condors were doing. Study Co author Hannah Williams a postdoctoral researcher at the Max Planck Institute for Animal Behavior said in a press release. This suggests that decisions about when and where to land are crucial as not only do condor's need to be able to take off again but unnecessary landings will add significantly to their overall flight costs. All of which means that in Congress must understand how to use thermals, thermals being invisible patterns and bubbles of air moving all around in the atmosphere to their advantage, and they must understand this much better than scientists previously gave them credit for.
