Main points:

• The researcher was originally just trying to see what birds' takeoff patterns were like while running, but then turned the camera backwards on basically a whim.
• They only poop while flying (every 4-10 min), probably because it may be easier for them than while on the water; it lightens their total flight weight, and reduces guano getting stuck to their bodies (which could otherwise make them smelly targets for predators)
• Their crap is full of phosphorus and nitrogen and fuels coral and fish population growth quite significantly (seabird regions show a noticeable difference)

Didn't expect to read this today, but here we are.
