In flight their heart rate is 1000 beats per minute and their body temperature approaches 105F (40C) - their high metabolism might explain a more tolerant immune response.

- Quikinterp 5y agoI don't know much about biology, what advantages does having a heart rate that fast have for a bat?
- tibbydudeza 5y agoBirds can extract more oxygen from each breath compared to bats - besides lungs they have additional air "storage" places called air sacs in their body. Their lungs do not contract like mammals but the air sacs do - so when they exhale their lungs are still performing a gas exchange.

- ak217 5y agoEnabling the high metabolic flux required to fly. As the only flying mammals, bats have the highest metabolism among mammals while also being more biologically compatible with us compared to e.g. birds.
- tibbydudeza 5y agoA rather suboptimal evolutionary path - birds are way better adapted to flight at lower cost but then again they had a 100 million year head start (theropod dinosaurs) compared to bats.
