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.
Birds do not have the same sensitivity to capsaicin as mammals, as they lack a specific pain receptor. Chili peppers are eaten by birds living in the chili peppers' natural range, possibly contributing to seed dispersal and evolution of the protective capsaicin in chili peppers, as a bird in flight can spread the seeds further away from the ...

The capsaicin "pharmacophore", the portion of the molecule that produces biological effects The class of compounds causing pungency in plants such as chili peppers is called capsaicinoids , which display a linear correlation between concentration and Scoville scale, and may vary in content during ripening .

Bird's eye chilis of assorted colors. The bird's eye chili plant is a perennial with small, tapering fruits, often two or three, at a node. The fruits are very pungent. The bird's eye chili is small, but is quite hot. It measures around 50,000 – 100,000 Scoville units, which is less than a habanero, but many times hotter than the spiciest ...
