they have no heat receptors?? capsaicin literally triggers the ion channel for thermosensing.
- burnished 2y agoProbably a different channel that isn't triggered by capsaicin
- sitharus 2y agoCapsaicin binds to TRPV1 receptors, which are mammal-specific. Other animals have different proteins in this role and birds in particular are not sensitive to it. Also TVRP1 is only triggered by temperatures over 43°C, lower temperatures are sensed by other proteins. Capsaicin isn’t just effective on mammals, it also has an effect on some fungi and insects, though mostly through metabolic disruption.

- widforss 2y agoHave you seen birds swimming in the winter? Doubt they care much about temperature. /s
