Valle de Oro NWR - construction and Cliff Swallows

Brief description: 
Valle de Oro observers have been documenting nesting timing of Cliff Swallows in the old milk barn building at the Refuge. Demolition of the milk barn was slated for this year, and Refuge staff were able to use the information about when the Swallows nested over the last few years to know when it was safe to demolish the barn so as not to destroy nests of the Swallows.
