Do YOU speak chicken? Take the test to find out

Do YOU speak chicken? Scientists say you can tell how birds are feeling based on their noises – so can you decipher these clucks?

  • AI technology from Japan is able to decipher the meaning of chicken noises 
  • The birds are already known to show empathy and ‘feel’ each other’s pain

From clucks to squawks and even ‘growling’, the meanings behind chicken sounds have always been a mystery, even to farmers.

Not any more, however, because artificial intelligence (AI) technology from Japan has finally been able to translate them – giving a unique insight into a chicken’s wellbeing. 

Experts trained an AI model with about 100 hours of chicken recordings until it could allegedly identify whether a bird was happy, sad or frightened with 80 per cent accuracy. 

The scientists used machine learning (ML), a specific subset of AI that allows systems to learn and come to informed conclusions. 

Audio clips released by the experts show the wide range of noises that the birds make – but can you identify a chicken’s emotion as efficiently as an AI?

Humans can look forward to more ‘meaningful’ interactions with chickens thanks to the study results, according to researchers

The research was led by Professor Adrian David Cheok at the the University of Tokyo, who is known for his expertise in the area of sex robots. 

‘It’s a cluckin’ great leap for science and this is just the beginning,’ Professor Cheok said. 

‘We hope to be able to adapt these AI and ML techniques to other animals and lay the ground work for incredible intelligence in the various animal-related industries. 

‘If we know what animals are feeling we can design a much better world for them.’ 

According to the academic, his team is now planning to create a free app so that farmers in the UK and Australia can make use of the technology.

It will analyse chicken sounds and determine what the bird is feeling – whether it is happy, sad, anxious or just hungry. 

A proof-of-concept study has been published as a draft on the research website Research Square, which means it has yet to be peer reviewed, although the team has submitted it to Nature Scientific Reports.

What is machine learning? 

Machine learning (ML) is a branch of AI based on the idea that systems can learn from data, identify patterns and make decisions.

ML systems can learn to improve their ability to perform a task without being explicitly programmed to do so.

Such systems can find patterns or trends in data to make conclusions or help humans make better decisions. 

Machine learning systems get more effective over time as they acquire more understanding.

For the study, Professor Cheok and colleagues began with around 200 hours of recordings from 80 chickens. 

Vocalisations from the birds in various conditions were recorded before being ‘meticulously’ analysed, initially by humans. 

The team collaborated with eight animal psychologists and veterinary surgeons, who provided expert insights into the emotional states of the chickens.

Once the emotions of the chicken noises had been identified by the expert humans, the study authors were able to train their model with the data.

The model was fed with about 100 hours of chicken sounds, comprising short clips, each labelled with its corresponding emotional state. 

Once the AI had been trained, the team tested its accuracy with another 100 hours of fresh chicken sounds that hadn’t been used during the training phase. 

Researchers found it was able to discern the meanings of the chicken sounds with around 80 per cent accuracy for various emotions – happiness, fear, hunger, tiredness and pain. 

This graph shows the AI model’s accuracy level for correctly detecting happiness from the chicken recordings – just above 80 per cent 

New chicken recordings could be fed into the model to identify how birds are feeling – potentially in the form of a new software product. This could be helpful for farmers if they hear their birds making certain sounds but have no idea what they mean about their wellbeing

The team describes chickens as ‘highly social animals’ with complex cognitive abilities and emotional experiences. 

Their cognitive capacities include perception, learning, memory and even problem-solving, while emotions range from happiness, anxiety and fear. 

The researchers claim their ‘groundbreaking’ work is ‘bridging the gap between human and animal communication’. 

‘This research not only opens up new avenues for understanding and improving animal welfare but also sets a precedent for further studies in AI-driven interspecies communication,’ they said. 

Chickens are already known to have emotional intelligence. A landmark 2011 study found females showed clear signs of anxiety when their young were in distress.

Such signs included increased alertness, higher heart rates, lowered eye temperature clucking noises towards the chicks.

The British research showed for the first time that birds display empathy – the ability to feel someone’s pain or see their point of view. 

Chickens were WORSHIPPED rather than eaten in Iron Age Britain: Birds were often buried ceremonially alongside people, study finds 

Today, chickens are a staple of the farmer’s paddock and one of the world’s most intensively farmed meats.

But new research shows the birds were originally worshipped and revered as companions. 

Experts analysed historical chicken remains found in more than 600 sites in 89 countries, including England, Italy, Turkey, Morocco and Thailand. 

Results suggest the bird was first domesticated only 3,500 years ago in southeast Asia before spreading west to Europe. 

Domestication was triggered by dry rice farming, which drew wild jungle fowl, the modern chicken’s ancestor, down from the trees in around 1500BC. 

Prior to this, chickens were regarded as ‘exotica’ – unusual or tropical because they came from another country – and were buried alongside humans.
