Stimulation of the cloacae of captive nestlings induces defecation (Rand 1937, Weisbrod 1965). Nestlings defecate after every second or third feeding. Feces of captive birds no longer enclosed in sacs after about 40 min postfledging (Weisbrod 1965). Weisbrod (1965) also described flatulence accompanying defecation by adult jays observed on cold mornings. No information on defecation rates of adults.
So tell me--just how was this flatulence "described"? I can't wait to get ahold of a copy of Weisbrod, A. R. 1965. The maintenance activities of the Blue Jay, Cyanocitta cristata . M.S. thesis, Cornell Univ., Ithaca, NY.
Mother never told me there'd be days like this. But she also said never to tell fart jokes on cold mornings. I didn't know I could write a whole dissertation about it!
