Join the Audubon Society of Portland, Urban Greenspaces Institute, and other partners in The Intertwine Alliance in celebrating more than a quarter century since the Great Blue Heron was adopted as Portland’s official city bird. This year’s Great Blue Herons of The Intertwine festivities will also celebrate the City of Portland’s designation by the United Nations’ Environmental Programme as the North American host city for the World Environment Day on June 5th.

The City of Portland Environmental Services partners with dozens of organizations from the region as part of the Intertwine Alliance, a coalition seeking to protect investment in and conservation of parks and natural areas.
