New and Seasonal: 

Shorebirds are back!

The first fall migrants on shorebirds' long journeys, some from the Arctic to South America, are already on the mudflats on ay shores. Hundreds of Western sandpipers feasted at the mouth of Strawberry Creek during our July 15 work party with Integrated Project Management. Click here for our video on how these birds need mudflats like those at the mouths of Strawberry, Schoolhouse, and Codornices Creeks -- all places where F5C volunteers are active.
