Observing real-time social interaction via telecommunication methods in budgerigars (Melopsittacus undulatus)

We built a system for two animals to interact via audio-visual equipment in real-time, to compare behavioral differences between two conditions, an “interactive two-way condition” and a “non-interactive (one-way) condition.” We measured birds' responses to stimuli which appeared in these two conditions. We used budgerigars, which are small, gregarious birds, and found that the frequency of vocal interaction with other individuals did not differ between the two conditions. However, body synchrony between the two birds was observed more often in the interactive condition, suggesting budgerigars recognized the difference between these interactive and non-interactive conditions on some level.
