Swift Count Community Science Project

Since 2009, the Portland Audubon has been counting Vaux’s Swifts at Chapman Elementary School and at a number of other sites in the Portland-metro region as part of a community science project. These counts contribute toward a larger Pacific Coast-wide effort to keep track of the swift population.

Want to count Vaux’s Swifts to help with this effort? Each August we hold a training for volunteers so we can count each night in September while the Swifts are migrating south. For more information and to get involved, visit our community science page.
