Birds that constantly catch insects on the fly. Their legs tend to be short and their feet not adapted for walking or hopping on the ground without the aid of their wings. Because of their diet, these birds are not present in our area in winter. The birds shown on this page are not closely related, merely grouped here for identification purposes.
