PURPLE MARTIN
The Purple Martin is an uncommon, but locally common breeder in the CW Region. These often colonial birds historically nested in tree cavities, but many populations in our area are now largely dependant on man-made "martin houses". Preferred habitat is usually open fields or open areas near water. Data on this species is too limited to draw any conclusions. Photo: © Eric Secker |
