Purple Martin Eagle Project


Troop 70 maintains three purple martin houses in Bee Cave Central Park. Purple martins are a species of bird that feed heavily on both mosquitoes and invasive fire ants, so they are quite beneficial to the environment. Local populations of martins have been declining in recent years, so the houses are meant to provide shelter and attract more martins to the area.

The houses were constructed in 2017 as the Eagle Scout Project and Hornaday Project of Scout Brian Jessich. The houses are regularly maintained twice a year, at the beginning and end of the martins' nesting period. If any damages are noticed, pleased report them to the Scout currently in charge of maintenance:

More information on the Hornaday Program can be found on the BSA website ​here​. 

Maintenance consists of cleaning out the compartments of leftover nests, tightening any loose screws, reapplying sealant in the grooves, and repainting as needed. Depending on the season, clothespins are removed (Feb. 1) from or put on (Aug. 1) the entry holes. This ensures that no other birds will nest in the house while the martins are away.

Reports of successful nesting pairs can be entered into the Purple Martin Conservation Association website ​here​.  This will help ornithologists better understand purple martin migration patterns and habitat status.
