The city logo features the purple outline of a bird inspired by the Purple Martin, a protected migratory songbird.
Lewisville is home to the largest Purple Martin roost in North Texas and one of the largest in the state. It is estimated that more than 50,000 birds return each year to Lewisville, arriving in late February or early March and staying for six months to build nests, raise their young and prepare for their non-stop flight across the Gulf of Mexico to their winter home in Brazil.
The birds make their temporary homes across Lewisville and surrounding areas, favoring manmade homes in populated areas, especially those near a stable water source such as Lewisville Lake. Many area residents erect martin houses in order to attract these graceful visitors. The city already has martin houses at local parks, but this is the first time houses have been placed at an occupied city facility.
When egg-laying season begins, the Purple Martins form a single roosting area near Main Street and Civic Circle. The roost can start in the second half of July and last into the early part of September, depending on weather conditions and food supply. Hundreds of bird-lovers visit Lewisville each year near sunset to view the roost and watch the aerial acrobatics of the Purple Martins.
Two multi-story Purple Martin houses are located on the grounds of Lewisville City Hall, three large martin houses are located at Fred Herring Recreation Center, and similar houses have been installed in several city parks.
Purple Martin Landlords of North Texas is a regional association of bird-lovers who care for Purple Martins at their own homes and regularly visit Lewisville to view the local roost. Landlords member Kenny Crawford worked with City Cable LVTV to create a brief video showing how to build a martin house and attract Purple Martins. [WATCH VIDEO HERE]
