Purple Martin

The purple martin is a passerine bird in the swallow family Hirundinidae. It is the largest swallow in North America. Despite its name, the purple martin is not truly purple. Purple martins' breeding range is throughout temperate North America. Their breeding habitat is open areas across eastern North America, and also some locations on the west coast from British Columbia to Mexico. Martins make their nests in cavities, either natural or artificial. Purple martins feed entirely on insects. Vast amounts of insects, caught in flight, are consumed daily. A popular misconception is that martins are a major predator of mosquitoes. Extensive studies of feeding habits have shown that mosquitoes make up less than 3% of the martin's daily diet. Purple Martins sing with boisterous, throaty chirps and creaky rattles. During courtship, males make a croak song that can be 4 seconds long; he only does this when a female is nearby, often before dawn and from inside the nest cavity. Females make a chortle song. The loudest song is the dawn song, which males sing before daylight, possibly to attract other martins to the colonial nest site. The building blocks of their songs are also used as calls, in a variety of situations. In addition, martins make a hee-hee call while fighting over territories and zwrack and zweet calls during stressful interaction with other species. Females use a choo call for leading fledglings. Males sometimes make click sounds during courtship by snapping their bills together. Here to the sounds of this little purple bird.
