![]() ![]() The call to warn of a ground-based predator like a fox (or a human) is a clucking sound and very different to the high-pitched “eeeee” used to warn of a hawk flying overhead.īirds which didn’t see a predator but heard the warning call responded in the same way as the bird that did see the predator by hiding or taking cover. ![]() What they discovered was that calls are specific to the danger. Remote cameras and audio equipment then recorded what happened so they knew the birds weren’t responding to any human interference They recorded different warning calls and made videos or high resolution animations of predators, then played the audio and visuals to test what the birds would do. Researchers testing a flock’s response used rigorous procedures to make sure the birds were reacting as naturally as possible. ![]() These can differ according to the perceived threat, and research into alarm calls has revealed that chickens are actually pretty smart.Ī call to warn of an overhead threat like a hawk will be different in intensity to one that warns of a dog trotting past outside the run or a person approaching. This shows that females track the male’s reputation for honesty.” So females also remember which males call without food and stop responding to them. He can then court her (using a display called waltzing) or even attempt to force copulate with her (not everything in the chicken world is nice). “Some males will call and display when they haven’t found food, ‘hoping’ that the female will still approach him. This sneaky behaviour allows the subordinate to feed a hen while avoiding punishment from the dominant male. The hen sees the display, recognises that the subordinate has food, and takes the food from him. “Subordinate roosters often just do the visual display without making a sound. “As an aside, females eavesdrop on the male’s interactions with other females and remember which ones are the best providers overall for the whole group, Why should a male give up food for the female? The reason is that females prefer to mate with the male that provides the most food. “The female usually responds by approaching and taking the food from him. He’ll often pick it up and drop it repeatedly, suppressing the urge to eat the tasty morsel. He starts by giving a series of staccato calls and bobbing his head up and down, using his beak to point towards the food. “Let’s take the example of what happens when a male finds a high-quality food item in the presence of a female. She has studied the communications of chickens and says they are quite sophisticated in how they ‘speak’ to each other. It is most commonly heard when a bird is picked up or when a feather is pulled out.ġ0 tips for growing good seedling transplantsĭr Carolynn ‘K-lynn’ Smith is an ethologist (someone who studies animal behaviour) with Macquarie University in Australia. A cry of pain is similar to the alarm call but is usually only a single squawk. You’ll often hear this when you pick up a bird which is unaccustomed to being caught, and it may continue until you put her down again. In the wild this would be an alert to call the resident rooster so he could escort the hen safely back to the flock. It can become more strident when the danger recedes, as if they’re saying “phew, we escaped that one, stand down.” You’ll also often hear it when a hen has finished laying and is leaving the nest. This is the soft alarm sound when a danger is perceived. This is the usual talkative sound you’ll hear when a relaxed bird is wanting food, or looking for a nest to lay an egg. There may be a variety of causes, from something minor like a bit of dust in their nasal cavities, to a parasitic infection with gape worm in the throat, to a full-blown viral infection of the lungs and air sacs. ![]() These are pretty similar noises to those humans make and can all mean a bird is unwell. SNIFFING, SNEEZING, COUGHING AND GURGLING They also communicate using posture – head up, head down, tail up, tail down, feathers spread, wings flapping – but what they’re ‘saying’ can mean different things depending on context.ġ. Once you can identify the noises and their meanings, you’ll be better able to identify what is normal and what might mean trouble in your flock.īirds aren’t limited to sound though. Poultry make a variety of sounds to communicate with each other, somewhere from 24-30 depending on the scientist. ![]()
