How do purple martins find food?

Purple martins get most of their food on the wing. This means while they are in flight. They catch most of the insects that they eat at altitudes between 150 and 500 feet.

It may seem odd that insects fly at this height, but they do. Insects can actually fly much higher than this, and purple martins will fly higher to catch insects if they need to.

Purple martins simply pluck insects out of the air. They are incredibly nimble and need to be. Spotting insects in the sky is tricky for us, but for purple martins, it is very easy. They have fantastic eyesight and can spot packs of insects in the sky easily. They will try and eat as many as they can before the insects spread out.
