Every September evening, thousands of Portlanders gather on a hillside to witness one of nature’s most incredible phenomena – the Portland Swifts diving into Chapman Elementary’s historic chimney. This mesmerizing display of Vaux’s swifts migration draws crowds from across the Pacific Northwest to experience what locals call “the greatest free show in Portland.”
What Are the Chapman Elementary Swifts?
The Chapman swifts are Vaux’s swifts, tiny migratory birds that use the school’s decommissioned chimney as a roosting site during their southward migration. These remarkable birds gather in massive swarms before diving into the chimney like “backward-traveling smoke” – creating a natural spectacle that rivals any organized entertainment.
Fast Facts About Portland Swifts:
- Peak numbers can exceed 11,000 birds in a single evening
- Each bird is only 4-5 inches long with incredible flying abilities
- They migrate from Alaska and Western Canada to Central America
- The Chapman Elementary chimney has hosted swifts for over 30 years

The Chapman Elementary Chimney: A Conservation Success Story
From Heating System to Bird Sanctuary
The Chapman chimney’s transformation represents a unique conservation partnership. Originally the school’s primary heating chimney, administrators delayed turning on heat each fall until the swifts departed – sometimes resulting in chilly September classrooms!
Around 2000, Portland Audubon Society partnered with grant organizations to fund a new heating system, dedicating the original chimney exclusively to swift roosting. The visible cables surrounding the structure were added for earthquake safety, ensuring this avian hotel remains secure for future generations.
Why Chimneys Matter for Swift Conservation
Vaux’s swifts naturally roost in large hollow trees, but habitat loss has made suitable trees increasingly rare. Chimneys provide critical substitute roosting sites throughout their migration route. The Chapman chimney can accommodate thousands of birds in its spacious interior – a testament to these tiny birds’ remarkable ability to share space.
