In Extremadura, Spain, I took an elegant picture of a Red-rumped swallow. This is the closest thing to being considered an "educational" picture. It clearly shows why the bird got its name - the rusty-red rump is clearly exposed. In addition, it is standing in the middle of the type of clay it uses to build its nest - and it shows how it transports the clay - in its bill! Here it is just about to lift off with its load to fly to the nest...
