The lambs chose the sound of their mothers much more often than the sounds of the unfamiliar ewes. The lambs could not see or smell the ewes, they could only hear them. In one study, 48-h-old lambs had to choose between the bleat of their mother in one location and the bleat of an unfamiliar ewe in a different location. Scientists count how many times a sheep chooses to walk toward and stay near the location of each sound. When the sheep hear the bleats, they can behave in various ways. One method that scientists use is to present the bleats in different locations, one on the left and one on the right ( Figure 1). But sheep cannot tell us the answer, so how do they respond in a two-choice test? If you heard a ewe bleat and a lamb bleat, could you correctly say which was the ewe? These are both examples of two-choice tests, in which you would answer by speaking. If you heard a dog bark and a cat meow, you could easily say which was the dog. The two-choice behavioral test helps us to understand whether animals can tell the difference between two sounds. But scientists do not only observe animals, they also create experiments using behavioral tests to investigate how sheep use bleats to communicate. It is a bit like when parents call their children who are too far away! These high-bleats are also emitted by adult sheep when they are separated from the herd, when they are stressed, and even when their food arrives late! From these observations we interpret low-bleats as comforting vocalizations and high-bleats as distress calls. High-bleats are emitted with the mouth wide open, when a ewe and her lamb are separated. Low-bleats are emitted with a closed mouth, when a ewe and her lamb are close to each other, during caregiving moments such as suckling or licking. Observing sheep this way, ethologists showed that lambs and their mothers (ewes) can communicate using what the ethologists called low- and high-bleats. To interpret the meaning of sheep vocalizations, ethologists often study their bleats and their behavior at the same time, using video cameras and microphones. The vocalizations of sheep are called bleats. Interpreting Sheep Sounds From Their Behavior By observing animals in farms, in zoos, or in nature, scientists called ethologists (who study animal behavior) have discovered that many animals can communicate using sounds, called vocalizations. If you do not do what they are asking, the dog might bark and the cat might meow, to insist that they really want you to do it, now! Barking and meowing are examples of animals using sounds produced by the mouth (like talking) to communicate. These animals are using behavior to communicate information.

A cat can ask for food by rubbing against your leg. A dog can ask you to throw a stick just by dropping it at your feet. Communicating With Soundĭo you think that animals other than people can communicate by talking to each other? Or what about communicating in ways besides talking? If you have ever lived with a pet, you probably know that animals are certainly capable of communicating with us. Studies show that sheep really can recognize each other’s voices and communicate vocally. They also investigate the brain to find out what is going on inside the heads of sheep when they hear and understand the sounds of other sheep. They study the sound waves of recorded bleats to identify each sheep’s unique voice and even determine which emotions the sheep are feeling. But do you think they also sound similar to the lambs? Or do you think the lambs know whose mother is calling and what they are saying? Scientists try to interpret the bleats of sheep by observing their behavior when they hear these sounds. To us, all these bleats sound very similar. Sheep also bleat when they are separated from the flock or stressed in some other way. If you have ever been out to the countryside in the spring, you might have heard sheep bleating to their lambs.
