In birds, the TRPV1 channel does not respond to capsaicin or related chemicals, but mammalian TRPV1 is very sensitive to it. This is advantageous to the plant, as chili pepper seeds consumed by birds pass through the digestive tract and can germinate later, whereas mammals have molar teeth that destroy such seeds and prevent them from germinating.
Capsaicin is a compound that can be extremely powerful depending on the concentration, and this was used to protect the seeds from predation, and increase their chance of survival. However, birds are not affected by the presence of capsicum and are able to eat the fruits and seeds.
Like capsaicin, it can deter mammals (but not birds or insects) from consuming plants or seeds (e.g. squirrels and bird feeder seeds). [3] This is consistent with nonivamide's role as a TRPV1 ion channel agonist. Mammalian TRPV1 is activated by heat and capsaicin, but the avian form is insensitive to capsaicin. [4]

The migratory nature of birds poses a distinct danger for the spreading of diseases. Without being affected by the infectious agent, birds can act as vectors in spreading psittacosis, salmonellosis, campylobacteriosis, mycobacteriosis, avian influenza, giardiasis and cryptosporidiosis. These zoonotic diseases can be transmitted to humans.
