Giraffes are the tallest of all land animals males (bulls) may exceed 5.

Newser is a USA TODAY content partner providing general news, commentary and coverage from around the Web. "Future studies should test in a well established experimental setting whether giraffes are more vocal when visual communication cues are absent," they conclude. Though the researchers couldn't prove the sound is used for communication, they found "suggestive hints" that the hum might serves as a "contact call, for example, to re-establish contact with herd mates." They speculate the hums may be occurring at night because giraffes' typically keen vision is less effective then. The hum isn't infrasound, but it's not exactly easy to hear either Wirednotes the researchers shared the vocalizations with zookeepers, and the sound was unfamiliar to them. They then analyzed the recordings visually, in a process they describe in BMC Research Notesas "time consuming, tedious, and very challenging." They believed the animals might produce "infrasonic vocalizations" - that is, below the level of human perception-and were looking for such low-frequency sounds.Īnd they did indeed find "structurally interesting humming vocalizations" that occurred mainly at night and hovered around 92 hertz in frequency as one New Scientist commenter notes, they sound a little like the Kraken (listen for yourself here). Here is an elephants video for toddlers, kindergarten, preschoolers and children to learn trumpeting, rumbling and roaring sound ef. As they grow up the become more silent or makes low frequency hums, some sc. 7:00 AM What Does the Giraffe Say Scientists Find the Answer It's not clear what tune they're humming, but it's important in social structure. The researchers recorded animals at three European zoos, amassing 947 hours of recordings over eight years. Giraffe Sound and Video (4k)The sound in the video is from a distressed juvenile. Though giraffes have a voice box, one line of thought was that due to their long necks it was too difficult for the creatures to generate the airflow needed to "vibrate their vocal folds."īut University of Vienna researchers now say they've determined that giraffes do indeed "produce vocalizations" that may serve as a means of communication. (NEWSER) – What does the giraffe say? For decades it’s been a simple answer: nothing, except for a snort or grunt every now and then.
