BirdLoop Project History

The Audubon BirdLoop at Marymoor Park has been the major Eastside Audubon conservation project for several years.  In July 2006, King County Parks Community Partnerships and Grants (CPG) program awarded $100,000 to Eastside Audubon for a two-year project to upgrade the interpretive trail at Marymoor Park into a world-class BirdLoop.  EAS has matched this grant with volunteer hours and money and has pledged to maintain the BirdLoop for the foreseeable future.


BirdLoop work parties have been held on the first Saturday of every month since March, 2006 in the rain, snow and heat.  

We removed invasive species such as Scotch Broom and Reed Canary Grass in the meadow, along with blackberry vines that were choking out native trees and shrubs. We also planted hundreds of native trees, bushes, grasses, and ground cover in at least ten areas in the meadow.

Five interpretive signs with lovely artwork were commissioned and installed along the BirdLoop.  We also refurbished two county transit kiosks for the Meadow and River entrances to the BirdLoop.  The Eastside Audubon Photography Group donated bird images for our posters.  

We developed two trail extensions to move the BirdLoop route further from the dog area so our visitors can enjoy the birds in greater quiet.  A gate was installed between the dog area and the meadow.  We are in the process of completing the final project in the original grant: building and installing 100 feet of boardwalk extension to keep our feet dry during the winter rains.

Finally, for our bike racks, we commissioned a beautiful sculpture showing a heron in the reeds.

King County has minimal funds for future work, but we are exploring other sources of funding, including Washington Wildlife and Recreation Program matching funds. 


We expect our first Saturday native plant and habitat maintenance work parties to continue for the foreseeable future and would welcome any help you can give us with funding the work we do.
