Why do birds have lower BMRs than mammals?

Mammals with muscle masses <30% of body mass have lower BMRs, a diminished capacity to regulate body temperature and often have reduced activity levels. At muscle masses <42% of body mass, birds have body temperatures and basal rates higher than mammals with the same muscle mass.

Why don’t birds like flying?

Unlike man, who has always dreamt of flying, some birds will eagerly shed this evolutionary advantage if it no longer suits them. To remain airborne it helps if you have hollow bones to keep the baggage limit down. However, if you’re adapted to dive for fish, then having a denser structure helps you become less buoyant.
