(NPR) — If you've ever listened to karaoke at a bar, you know that drinking can affect how well someone can sing. Christopher Olson and his colleagues at Oregon Health and Science University recently set out to find if the same was true for birds, specifically zebra finches.
"We just showed up in the morning and mixed a little bit of juice with 6 percent alcohol, and put it in their water bottles and put it in the cages," Olson told All Things Considered's Arun Rath. "At first we were thinking that they wouldn't drink on their own because, you know, a lot of animals just won't touch the stuff. But they seem to tolerate it pretty well and be somewhat willing to consume it."
The finches long have been used as a model to study human vocal learning, or how people learn to communicate using language, Olson said. Obviously, alcohol affects human speech, so Olson and his team checked for similar problems with the birds.
