As most of us know, purple martin eats a variety of insects including leafhoppers, flies, bees, wasps, cicadas, mosquitos, moths, butterflies, termites, mayflies, beetles, and many others.  If purple martins are nesting nearby, we routinely see them capturing them in midair close to the ground. However, it is not widely known that purple martins also hunt high above the earth.  These hunting forays take place at altitudes ranging from 150 to 500 feet in the sky.  Wow!
