He reported on how mice fed a similar diet develop pathological changes in hormones and metabolism, as would be expected. But, doves fed a similar diet did not seem to show any notable […]

Very high intensity exercise: hovering

I just read an interesting review published in Physiology of flight energetics and fuel use in nectar feeding hummingbirds and bats. While flight is considered pretty high intensity exercise, hovering flight is even more demanding. Hummingbirds and nectar feeding bats are really tiny and thus have very high metabolisms to maintain body heat. Some of these animals are also migratory, which is an even greater energy demand. Remarkably, they sustain […]
