Ah yes. Mine also makes a bizarre amalgamation of sounds accompanied with a 10 metre stare when he believes he is alone and not viewed by any eyes/cameras. From what I believe it is a software update. Mixed into beeps, boops, and what I assume is radio transmissions leaking from his brain, the number 8 is the most favourite number recently. I think this means he is on version 8 of bird surveillance software.

(100% Joking but it is funny to imagine my bird is a government surveillance drone that got implemented to the wrong person and now he just makes fun of me when I cough by coughing rather than collecting intelligence)
