Put up a Purple Martin house in your backyard, and you just might be treated to a close-up look at these engaging birds all through the breeding season. Attach a guard to keep predators from raiding eggs and young. Find out more about nest boxes on our Attract Birds pages. You'll find plans for building a nest box of the appropriate size on our All About Birdhouses site.
You can put out crushed eggshells to give the martins a source of grit for digesting insect exoskeletons.
Find This Bird
In eastern North America during the summer, look for Purple Martins around martin houses, the miniature condominiums that many people put up in yards. The birds are more challenging to find in the West, where they nest in woodpecker holes in dead snags. Foraging Purple Martins hunt insects higher in the air than other swallows, but in the afternoon and evening they may feed low and close to nest sites. In late summer you might see enormous roosts of Purple Martins, particularly in the Southeast as they prepare to cross the Gulf of Mexico.
Purple Martins are a focal species in Project NestWatch. Learn more about them and contribute your data at their Purple Martin page.
House Sparrows and European Starlings are major competitors for martin nest boxes and can keep Purple Martins from breeding. Our Project NestWatch offers some suggestions for deterring these non-native species.
Our eBird project is a great way to keep track of the dates Purple Martins arrive and depart each year, and any other sightings in between.
