Lor Gynoid asked:
Do those drab birds live longer because they’re putting less energy into making themselves look gorgeous?
I don’t think so. I think the point is they’re not doing so well anyway because they’ve got less food. In nature I suppose if they did want to live longer by not having such fancy feathers it might give you a bit of a helping hand. That’s something I think we need to study as well because I think that guy was keeping those creatures a bit hungry. I don’t suppose they would have lived as long!
