This is the reason why hummingbirds are the most amazing creatures and their blood should be studied, more deeply. They basically have the ability to pull in oxygen at an order of magnitude greater ppm than hemoglobin based mammals... But their metabolism requires a really high sugar intake constantly. But their speed and endurance is stunning, some humming birds migrate btwn north and south america.... They are also fiercely territorial - ive witnessed two fight literally two feet from me - attacking and pecking at eachother, with the loser of the battle falling on the ground... (whom i picked up and brought him to bart in an uber i was catching - he woke up and escaped my grip and i was in an uber with a hummingbird flying around... ill never forget that experience, the driver loved it)

We have a hummingbird feeder outside our kitchen window. Watching their antics all summer long is a great source of entertainment. The feeder has six feeding spots, but of course they chase each other off so that only one can feed at a time. Sometimes a wasp is at the feeder and the wasp and hummingbird tolerate each other.
