There's of course hovering, which not all birds can do (hummingbirds can!). The chapter covered aerodynamic power, the type of flapping to create certain speeds, minimum and maximum range speeds, and even types of soaring.
While all of this info was interesting, I was definitely more interested in the visual aspects of flight, and I really loved how part of the chapter focused on soaring. The book really explain well how birds like our native Turkey Vulture can stay in the air for so long, even on super windy days! I 'm always so scared that one is going to get pushed by a gust of wind into the road and get hurt. What I learned though, was that even our vultures are adapted well to this scenario:

Of course, here's a Turkey Vulture to enjoy after all that info about soaring: enjoy!
