Purple Martins are a highly sought out beloved songbird, particularly in the Eastern United States. With a length of 7-8 inches Purple Martins are the largest swallows in North America and one of the largest in the world. Different ages and genders of Purple Martins migrate at different times. Older males typically migrate first, followed by older females and then the younger birds. Purple Martins are colony birds. Nesting colonies may grow to hundreds of pairs of birds. Purple Martins eat mostly flying insects, and catch their prey in midair. Centuries ago Native Americans hung out hallowed out gourds for Purple Martins to nest in, hoping to attract them to help keep insects away from their crops. Today, Purple Martins are almost 100 percent dependent on human supplied housing for their nesting colonies. We have several Purple Martin Houses to choose from.
