Scientific American: Parrots are taking over the world
UC researcher explains why parrots are so adaptable
Scientific American turned to a University of Cincinnati researcher to explain what makes parrots so adaptable, particularly in cities they share with people.
According to the magazine, at least 60 of the world's 380 parrot species have breeding populations outside their historic geographic range. These transplants are thriving in new places where they have learned to adapt.
“They're animals that are really social. They live in cognitively complex social environments,” Grace Smith-Vidaurre, a postdoctoral fellow at the University of Cincinnati, told Scientific American. “They're like humans in a lot of ways.”
Smith-Vidaurre studies birds in UC Assistant Professor Elizabeth Hobson's lab.
Monk parakeets, in particular, have adapted to city life in places like Chicago, New Jersey, and Brooklyn, New York. They were introduced to the United States from South America through the pet trade.
So far, concerns that monk parakeets would become an agricultural pest in the United States have not come true. Instead, they seem to enjoy city life.
Now Smith-Vidaurre is comparing the vocalizations of the U.S. birds to those found in their native South America. She found that the calls made by birds living in this noisy city soundscape are less complex than those found in South America.
“Something about their environment might be constraining their ability to produce or perceive these vocal signatures,” she says.
