🐾 Pets · Plants Birds Don't Experience Chili Heat Like Humans Do

[Beatriz9]

Capsaicin activates a heat-sensitive receptor in humans and many other mammals, producing the familiar burning sensation.

Bird versions of the receptor are much less sensitive to capsaicin.

This allows birds to eat fruits containing hot peppers without experiencing the intense burn that mammals do.

That difference is useful to pepper plants because birds can swallow seeds and disperse them without destroying them through chewing.

A chili that feels painfully hot to you can be a very different sensory experience for a bird.

Sobrang galing ng biology fact na ito boss! Dahil walang TRPV1 pain receptor ang mga ibon para sa capsaicin, nagagawa nilang kumain ng sili at mag-disperse ng seeds sa iba't ibang lugar nang hindi naiirita. Salamat sa share!
