By now you’re probably asking yourself which Black Star chickens are loudest.
And if you answered, “all of them,” you’re in luck.
In a new study by researchers at the University of Washington, scientists have determined that the birds have a “dynamical resonance” that allows them to communicate in a way that humans can’t.
The findings, which were published online Monday in the journal PLOS ONE, may have implications for the way that the Black Star chicks are raised, or how we might treat the birds.
Here’s how the researchers described the phenomenon: “To create a dynamic resonance, the birds need to know that we’re around,” said the study’s lead author, David L. Krieger, an assistant professor of zoology and animal behavior at UW.
“The resonance is the ability of the birds to know the other birds around them and make noise about it.”
The resonance, known as “dynamic resonance,” occurs when the birds are playing with the objects they’re using as play toys.
In other words, the researchers’ study found that birds who were not interacting with the toys were quieter and had a lower resonant frequency.
This resonance allows the birds and the toy to communicate, but it’s not as loud as the more normal resonance that occurs when they’re playing with something.
When the researchers turned to a different kind of toy, the resonance increased and the birds became louder, Krieer said.
“What we’ve found is that this dynamic resonance is important for communication,” he said.
The researchers used sound waves to record the sounds of the Black Stars from the back of their heads to the front of their necks.
They found that the resonance varied with how far they looked at the toy.
When they looked back, they heard their own resonant frequencies and the resonance of other birds, as well as other toys that they played with.
“This is not a surprising result because we’ve known that there is a dynamic resonant to communication, and the bird will use this to communicate,” Krieberg said.
In addition to the resonance effect, birds who used the toy had a higher resonance frequency when they played a different sound.
“They have a resonant that is quite distinct,” Kueger said.
What’s more, the results of the study also show that the bird’s resonance is also reflected in the toys they use to play.
“We’ve found that when the bird uses a toy, it has a different resonant than when it uses a real toy,” Kreeger said, “so we’ve got this interesting dynamic resonance that we can think about in the future and that’s really interesting for us.”
In addition, the team found that some of the toys used by the Black-Star chicks actually increased their resonance frequency, which is “a really good example of dynamic resonance,” Kieger said “because if we can use a toy to make noise, it’s kind of like playing a song.”
“When the birds use a real or imitation toy, they are also playing with it,” Kriemer said.
This is one way that we might consider toys as toys.
And Kriefer said it’s a common way that people “use toys to communicate.”
“I would say it’s one of the most effective ways that we use toys, and that is that we have a dynamic to communicating, which can be a good thing,” he told ESPN.
“I don’t know that I could find a better example of that dynamic than this.”
The researchers noted that the researchers did not study the resonance frequency of the toy they were using, and could not definitively say that it is higher in the Black Rose birds than the Blackstar birds.
“But we have to be careful because when we use a particular toy, we can have a lot of fun, and you might even hear yourself in that toy,” L.J. Kieffer said.
And since they could not determine which toy the birds were using to communicate with, the authors said that the results could not be used to recommend which toy should be used by each bird.
“In general, we do not recommend that we keep toys in our homes that are too loud,” K.K. Kielger said of toys.
“You might be able to tell which toys the bird is using but that’s not necessarily a very good way to do it.”
And even when they do know which toys to use, the research team cautioned that “there are probably some toys that are just fine to play with,” Kieler said, and said that it would be important to consider whether the toys the birds used were too loud and if so, whether to limit their use.
“It’s possible that one toy may be too loud for a particular bird,” Kreimer said.
Krieser said the findings of the research “should be of interest to anyone who’s considering raising Black Stars, and is something that we should continue to
