From the author: We examined the vocal responsiveness of chicken (Gallus gallus) embryos at the pipped egg stage to determine if they were able to regulate their thermal environment by soliciting heat from a surrogate parent. There was no overall effect on vocalizations of exposure to 20 [degrees] C or 45 [degrees] C relative to the normal incubation temperature of 37.8 [degrees] C. There was, however, a general trend towards increased calling as the time of hatching approached. There was also some indication that embryos tested in the late stages of hatching (ringing) vocalized more in the cold, then became relatively silent when rewarmed. When cold-challenged embryos were given 2 min of rewarming (surrogate brooding) in response to their calls body temperature was slightly but significantly elevated above cold only exposed controls. Unlike previously reported anecdotal evidence suggesting a strong vocal response to cold, our results suggest chicken embryos show only weak incipient vocal response to temperature that begins to increase late in incubation and becomes fully functional only after hatching. Unlike other species tested to date, the developmental progression of behavioral and metabolic thermoregulation appear to be tightly linked in this species.
