Once the birds had learned how to initiate video interactions, the second phase of the experiment could begin. In this “open call” period, the 15 participating birds could make calls freely; they also got to choose which bird to dial up. Over the next two months, pet parrots made 147 deliberate video calls to other birds. Their owners took detailed notes about the calls and recorded more than 1,000 hours of video footage that the researchers analyzed.
"A few significant findings emerged. The birds engaged in most calls for the maximum allowed time. They formed strong preferences—in the preliminary pilot study, Cunha’s bird Ellie, a Goffin’s cockatoo, became fast friends with a California-based African grey named Cookie. “It’s been over a year and they still talk,” Cunha says.
"According to Kleinberger, the types of vocalizations the birds used suggested they were mirroring the call and response nature they engage in in the wild—“hello, I’m here!” in parrot-speak."
There is a challenge where you put your hand near your dog like you're going to pet them but don't actually pet them. Someone tried it on their bird and it was adorable.
