Purple Martin (Progne subis)
Purple Martins live near water where tree cavities or banks are abundant for burrows. They also roost in nesting boxes. In certain situations, they make calls such as “hee-hee,” “choo,” or “zwack/zweet.” Purple Martins weigh 1.6-2.1 oz. and have a wingspan of 15.4-16.1 in. Their diet consists of flying insects, just like other swallows. They are protected on the US Migratory Bird lists.
