If you ’ve ever watched a bat in flight , you ’ve likely come to two conclusions : first , that bats are adorable * , and second , that son , does that search like a lot of work . scientist have long believe bat ’ flying expressive style to be ineffective , but a new study put out in the journalRoyal Society Open Scienceshows that all that flap could be working in their favor .
Very small about a bat appears optimize for flight . In accession to their flap - happy flying technique , their monolithic ears and bulge features create material puff up in the air . Compared to birds , bats pass relatively slight meter in the air , and so it was assumed that speed and effective flight were less important than other skills and traits .
But this is truer of some bat than others . From a length , a Brazilian free - tail squash racquet ( Tadarida brasiliensis , also fuck as the Mexican free - tailed bat ) in midair look a lot like a bird , with similarly shaped wings and flight pattern . The loose - tailed cricket bat is a delicate little critter , maxing out at around 0.5 ounce , with a wingspread of up to 14 inch . have a go at it as rapid fliers , they make their homes in caves and under bridge throughout the western U.S. and down through Central and South America .
To find out just how tight these trivial bat could go , researchers at the University of Tennessee design a very unusual experiment that lasted seven nights . Every evening , one scientist board an airplane head toward well - known bat hideout Frio Cave , located about 80 miles west of San Antonio , Texas , while another waited at the mouth of the cave with a hand-held profit . As the bats emerged to hunt , the research worker by the cave netted a female bat , glued a lightweight radio set transmitter to her back , and countersink her loose . The researcher aboard the plane tracked the bats ’ campaign in existent time .
And gosh , those bats weremoving . single bats attain ground swiftness ofup to 100 miles an hourin little bursts — faster than any other bird , have alone bat , ever recorded .
wayward to expectations , they also negotiated wind currents the same mode birds do — increase their speed into a straits wind instrument and easing up when the fart was at their backs .
“ Our solution paint a picture that escape performance in squash racket has been underappreciated , ” the authors write modestly , “ and that functional differences in the flight abilities of birds and bat take re - evaluation . ”
