Findings from a brand new examine investigating how birds expertise neophobia, which is the concern of latest issues, might play an important function in serving to to avoid wasting Critically Endangered species.
The analysis, revealed within the journal Royal Society Open Science, studied the habits of a uncommon hen referred to as the Bali myna (Leucopsar rothschildi), of which there are fewer than 50 residing within the wild.
Led by Dr. Rachael Miller of Anglia Ruskin University (ARU), alongside colleagues from Cambridge University and the National University of Singapore, the examine examined how 22 captive Bali myna birds responded to the presence of latest objects and sorts of meals, along with how nicely they tackled easy problem-solving duties.
The researchers imagine that gathering this sort of behavioral knowledge can help in new conservation methods. Behavioral flexibility is essential for a person’s adaptability and survival, and so pre-release coaching and figuring out particular birds for launch might assist with the profitable reintroduction of endangered species, such because the Bali myna, into the wild.
The examine was carried out over a six-week interval at three UK zoological collections—Waddesdon Manor (National Trust/ Rothschild Foundation), Cotswolds Wildlife Park and Gardens, and Birdworld—and the researchers discovered total that birds took longer to the touch acquainted meals when a novel merchandise was current.

Age was a key issue within the habits displayed, with grownup birds proving to be extra neophobic than juveniles. The researchers additionally found that the birds that rapidly touched acquainted meals that was positioned beside a brand new object had been additionally the quickest to unravel problem-solving duties.
This new examine is an element of a bigger challenge led by Dr. Miller, Lecturer in Animal Behavior at Anglia Ruskin University (ARU), aiming to mix avian cognition and habits analysis with conservation, to assist threatened species. Dr. Miller says that “neophobia could be helpful in that it might probably assist birds keep away from unfamiliar risks, however it might probably additionally impression their adaptation to new environments, equivalent to by means of an elevated reluctance to method new meals.”
“An understanding of behavioral flexibility, particularly how species and people inside that species reply to novelty and method new issues, is important for conservation, notably because the world is changing into more and more urbanized. Many species have to adapt to human-generated environmental adjustments and the way an animal responds to novelty can predict post-release outcomes throughout reintroductions.”
“We chosen the Bali myna for this examine particularly as a result of they’re on the point of extinction, with fewer than 50 adults within the wild in Indonesia, however there’s a captive breeding program of virtually 1,000 birds in zoos around the globe.”
“As a part of energetic conservation of the Bali myna, there’s a want to repeatedly launch birds to attempt to enhance the small, wild inhabitants. Now we have now knowledge on the behavioral flexibility of those birds, this might help to tell which birds could also be finest fitted to reintroduction. Our examine has already recognized that releasing juvenile Bali myna could doubtlessly be extra profitable than releasing grownup birds, no less than by way of adaptability to new environments.”
“Our knowledge can even assist with creating coaching earlier than launch, the place captive birds could be taught to extend concern responses to traps or folks, in the event that they had been to be launched in areas the place poaching takes place, or to lower neophobia by publicity to unfamiliar secure meals sources in areas with low sources. We imagine the general challenge findings will be capable to assist not simply the Bali myna, however hopefully many different endangered species.”
