i thought the same thing at first....but he reacts to the stuff cooking..."BITE"..."BITE"...nothing else we cook does this to him...he goes for rides....but the exhaust sounds seems to spook him....i have to just cruise easy and he's fine...we have to be careful outside here in the metro Detroit area...mosquitos carrying the west nile virus...they have already found dead crows here, so im careful to only take him out during the day before the vermin set in....i have a really sweet cage i modifyed to hang on a bedroom window and i can put him in thru the open window....the only way out is back into the bedroom...it is right up under the overhang and we have morning sun on that window....he has birds land on the cage and he "shares" his seeds by tossing them out on the ground..
"hey...come over here" the funniest stuff!
i also have a perch i made from 3/4 pvc pipe that hangs on the towel bar in my shower...if the water runs he freaks till he gets in...he loves the acoustics in the bathroom too!
