> But at least we (and all other animals with a secondary palate) can chew while breathing Interestingly, sprint predators such as cheetahs have to pause to get their breath back after a fast chase before they can eat their prey. In contrast, raptors such as falcons can eat immediately after a kill because they don't get out of breath in the same way. The avian respiratory system is actually quite different to ours, with relatively rigid lungs, separate air sacs to pump the air, and a one-way flow through the lungs, in contrast to mammalian lungs where the air goes in and out through the same pipe, and the lungs act as bellows as well as gas transfer devices.
