When bats squeak, they tend to squabble _ hawaii public radio-hpr2

If movies were trying to be more realistic, perhaps the way to summon Batman shouldn’t have been the Bat-Signal — it should have been the bat squeak.

New research from the Bat Lab for Neuro-Ecology at Tel Aviv University found that bats are “vocalizing” more information than many researchers previously thought. Hawaii vacation packages cheap And researchers were able to decipher what the bats were squeaking to each other about — often they were bickering over things like food, sleep and mating.


“It’s not as if now we can understand everything. Hawaii hotel package deals It’s not as if we have a bat-to-English dictionary,” says Dr. Honeymoon hawaii Yossi Yovel, a neuro-ecologist at Tel Aviv University and a member of the Bat Lab.

“But what we’ve found is that this cacophony that you could hear … Trip to hawaii for 4 actually contains much more information than previously believed. Oahu hawaii vacation packages So, all of [this] shouting, all of these vocalizations that were previously all categorized as aggressive vocalizations, we can now divide them,” Yovel tells NPR’s Scott Simon.

“For example, we can classify whether the bats are arguing over food or over mating or over sleeping position or over other contexts,” he says. Hawaii package deal “We can recognize the individuals vocalizing and we can even, to some extent, say who they are vocalizing to.”

In a recent study, Yovel, along with researchers Yosef Prat and Mor Taub, monitored groups of Egyptian fruit bats with 24-hour audio and video recording for two and a half months. Hawaii trips They say they analyzed almost 15,000 bat vocalizations.

Egyptian fruit bats are one of a small number of animal species to communicate one-on-one within their species, instead of “broadcasting” their message.

“Nearly all of the communication calls of the Egyptian fruit bat in the roost are emitted during aggressive pairwise interactions, involving squabbling over food or perching locations and protesting against mating attempts,” the researchers write.

“What they’re saying is stuff like: Why did you wake me up? Get out of my way,” Yovel says. Hawaii trips for cheap “In the case of mating, it’s usually the female protesting against a male who is trying to mate with her.”

Context in bat communication was one focus of the study. Best deals hawaii packages If we humans say the word “apple,” we imagine certain characteristics just from that word alone: a red color, a round shape, a certain taste, Yovel explains. Hawaii all inclusives vacation packages “This is something that is [a] very very important factor in human communication.”

He says animals almost never demonstrate this ability. Hawaii holiday deals But their research shows that vocalizations between bats have more of this type of context than researchers knew about before.

One goal of the research on bats is to apply it toward general knowledge of how different animals — including humans — communicate. Great deals to hawaii “It’s all part of a big question: How complex is animal communication?” Yovel says.

“Identifying context specific calls can be a first step toward the recovering of meaning in animal communication,” the researchers write. Hawaii cruise vacations “Understanding the encapsulated information in animal vocalizations is central to the study of sociality, communication, and language evolution.”

“Step by step we are getting closer to deciphering their communication,” Yovel says. Hotel and flight deals to hawaii “I don’t think we will — not in my time, at least — be able to really talk with them.”

Animals communicate – birds sing to woo their mates, the Cubs sing “Go Cubs Go,” BJ Leiderman wrote our theme music, wolves howl out to their pack members and fruit bats bicker.

SIMON: That symphony of squeaks is a cave of Egyptian fruit bats as they argue over food, mates and sleeping space. Vacation rentals hawaii Egyptian fruit bats are part of a small group of animals that communicate individually within their species – person to person, if you please, if you were a fruit bat. Cost of hawaii vacation Dr. Hawaii honeymoon packages Yossi Yovel is a neuro-ecologist at Tel Aviv University and part of the research team that is now decoding Egyptian fruit bat banter. Vacations to hawaii cheap Dr. Affordable vacation packages to hawaii Yovel, thanks very much for being with us.

YOVEL: So it’s not as if we can now understand everything, it’s not as if we have a bat to English dictionary. Hawaii things to do But what we found is that this cacophony that you could hear, which is very typical if you enter a bat cave, that’s exactly what it sounds like – actually contains much more information than previously believed. Hawaiian vacation packages for two So all of these shouting, all of these vocalizations that were previously all categorized as aggressive vocalizations, we can now divide them. Hawaiian tour package For example, we can classify whether the bats are arguing over food or over mating or over sleeping position or over other contacts. Travel hawaii We can recognize the individuals vocalizing, and we can even to some extent say who they are vocalizing to.

YOVEL: It’s only part of a big question – how complex is animal communication? When I say apple, you immediately imagine a red, round object, you know, with a certain taste. Hawaii trip for 2 This is something that is very, very important factor in human communication. Hawaii for vacation And animals have almost never been shown to have this ability. Vacation rentals in hawaii We show that bat vocalizations contain a lot of information about the context of the vocalization. Air hawaii packages For example, a third bat eavesdropping on a conversation between two individual bats can tell to some extent what is this conversation about, what is this argument about, which is more than we previously believed.

SIMON: So you mentioned food, mates and sleeping space. Hawaii family package deals So does this mean the bats are saying she’s mine, no, she’s mine? Or I’ll take that glop of whatever it is? Or you’ve got your claws on my head turn over?

YOVEL: Something like that. Discount hawaii vacation packages Maybe I should first point out – it’s very important that bats don’t only argue. Hawaii vacation home rentals OK. Hawaii rentals There are other vocalizations that bats emit.

YOVEL: Exactly. Best hawaiian vacation spots Yeah. Cheap hawaii vacation packages for families Some people get the wrong impression that bats only argue. Hawaii destinations vacation We, in purpose, wanted to take this huge bulk of aggressive vocalizations and see if we can classify them. All inclusive packages in hawaii And, indeed, I think – exactly like you suggested – I think what they’re saying is stuff like why did you wake me up, get out of my way. Trip to hawaii package deal In the case of mating, it’s usually the female protesting against a man who is trying to mate with her.

YOVEL: (Laughter) I can say that in another study we are following bats in Mexico, and these bats are actually flying over the U.S.-Mexican border, so if there is going to be a wall there, it will have to be very, very high.

YOVEL: You know, step by step we are getting closer to deciphering their communication. Trip hawaii package deal I don’t think we will, not in my time at least, be able to really talk with them, so to speak.
