Bird chemoreception

It irritates skin and mucous membranes. In terms of chemoreception, it irritates the trigeminal nerve. Capsaicin binds to the vanilloid receptor subtype 1 (VRl). Birds lack this receptor. Since they cannot sense capsaicin, they eat and distribute seeds of red hot peppers. Medically capsaicin is used as painkiller (analgesic). [Pg.64]

The once controversial concept of functional olfaction in birds is now firmly established on the basis of anatomical, behavioral, and physiological evidence. Olfactory structures are present in all birds examined and their general characteristics are the same as those of reptilian and mammalian olfactory systems. A notable difference in chemoreceptive systems appears to be the absence in birds of both the vomeronasal system and the terminal nerve. [Pg.365]
