These days, Theunissen keeps a few dozen zebra finches in aviaries on and around campus, 20 of which were used in this latest experiment.

They soon learned to differentiate between 16 different zebra finches. So it may be a sign of playing? The goal was to train them to respond to particular zebra finches by hearing several different renditions of those birds' distinct vocalizations and memorizing them. Your opinions are important to us. In fact, the zebra finches, both male and female, performed so well in the tests that four of them were given the more challenging task of distinguishing between 56 different zebra finches. Their teamwork yielded groundbreaking findings about the communication skills of zebra finches. By pecking a key inside the chamber, the bird subjects triggered an audio recording of a zebra finch vocalization. At what level is radiation totally safe for our body? If they pecked before the recording was finished, they moved to the next recording.

In a two-part experiment, 20 captive zebra finches were trained to distinguish between different birds and their vocalizations. On average, they succeeded in recognizing 42 different zebra finches, based on their signature sounds. Next, the zebra finches were introduced to more audio recordings from new zebra finches, to teach them to distinguish which vocalizations belonged to which bird. This document is subject to copyright. "They have what we call a 'fusion fission' society, where they split up and then come back together," Theunissen said. If they waited until the six-second recording ended, and it was part of the reward group, they received birdseed.

Moreover, they can remember each other's unique vocalizations for months and perhaps longer, the findings suggest. It is now clear that the songbird brain is wired for vocal communication.". That's because they can rapidly memorize the signature sounds of at least 50 different members of their flock, according to new research from the University of California, Berkeley. Over several trials, they learned which vocalizations would yield birdseed, and which ones to skip.
