Lemurs, with their piercing gaze, fluffy tails, and love for music, have always captivated our attention. Despite not being as closely related to us as monkeys and apes, we share many similarities with these unique creatures. Some of them bask in the sun, while others have a natural sense of rhythm. In fact, there are even some rare species of lemurs with striking blue eyes.
But did you know that just like humans, lemurs also have their own personal taste in music? Recent findings have revealed that these furry mammals have their own favorite tunes, with some preferring high-energy beats and others opting for the soothing melodies of the rainforest. The discovery was made by scientists who observed a group of bright-eyed and bushy-tailed lemurs at Blair Drummond Safari Park in Scotland.
To conduct their study, the researchers created a special place for the lemurs called the "Lemur Lounge." This wooden box was equipped with infrared sensors and a rotating selection of sounds, including the sounds of a rainforest, city noise, upbeat music, calming music, and white noise. The lemurs were free to enter the lounge and listen to their preferred sound for as long as they wanted.
Over the span of eight weeks, the lemurs were observed and their interactions with the sounds were recorded. The results showed that the lemurs preferred sound over silence when given the choice. However, the amount of time they spent with the sounds and their reactions varied across different species and individuals. This suggests that, like humans, lemurs have their own unique preferences when it comes to music.
Interestingly, the study also revealed that older lemurs tended to spend more time with the triggered sounds compared to their younger counterparts. They also played the sounds more frequently. This could suggest that the musical taste of lemurs changes as they age, just like it does for humans.
The partnership between zookeepers at Blair Drummond Safari Park and researchers from the University of Glasgow has been ongoing. Alasdair Gillies, the park's research coordinator, expressed his excitement about the study's findings, saying that it is fascinating to see how individual preferences may play a significant role in the design process, similar to the variations seen among different species.
Dr Ilyena Hirskyj-Douglas, from the University of Glasgow, led the study and hopes that the findings can be used to develop digital enrichment systems for lemurs living in zoos. She believes that technology can be used to enhance the lives of zoo animals by creating interactive systems that are tailored to their needs, interests, and abilities. However, she emphasizes the importance of taking the animal's preferences into account during the design process.
This research is the first of its kind, as it gave zoo-housed lemurs the opportunity to interact with a computer enrichment device. The lemurs' reactions to the Lemur Lounge provided valuable insights into their behavior and preferences, which could help in developing similar systems for other species in the future. This partnership between Blair Drummond Safari Park and the University of Glasgow is just the beginning of mapping out a future of animal-computer interaction, and it builds on previous studies that have shown the positive impact of audio enrichment on zoo animals' well-being.
