Description: The Bird_Inventory layer includes mapped locations of nesting sites and habitats for a range of bird species within Washington State, with a focus on sensitive and protected species such as the pileated woodpecker and purple martins. The data likely originates from the Washington Department of Fish and Wildlife (WDFW) and serves as a resource for ecological assessments, conservation planning, and regulatory compliance. Notable features include identified rookeries and documented nesting areas that may be subject to state or federal protection measures. This information supports informed decision-making for habitat preservation, development review, and environmental permitting.
