Every year Vaux's Swifts come to roost ( sleep ) at sunset to the chimney of the Chapman School in Portland. On the Audobun Society of Portland website the time fot this event is Sept 01, 2011- Sept 30, 2011.
Every year in late August, one of Portland’s most spectacular natural events begins: Thousands of Vaux’s Swifts gather in the city as they prepare to migrate to Central America and Venezuela.
Migrating swifts often use chimneys as roosts (places to sleep), and they are likely to return to the same roost year after year. One swift population has been returning to the Chapman chimney since the 1980s, and it is one of the largest known roosting sites of migrating Vaux's Swifts.
We can each bring a picnic to share with others and enjoy the show.
