According to the New York Times, a human newspaper definitely not written by birds, one cool thing that humans like to do nowadays is build giant bird nests to sleep in. Walking to a neighbor's house instead of flying there, eating normal human food besides seeds, and constructing humongous bird nests out of twigs— all things we humans do so often we don't even have to remind ourselves constantly to check and make sure we're doing them so as not to draw attention to ourselves.
