[Tweeters] Vaux's Happening 2024

[Larry Schwitters via Tweeters]

Audubon’s Vaux’s Happening ended their 26th consecutive Southbound survey of Vaux’s Swift communal, migratory, roost sites. We saw a lot of feathers. 132 observers made 629 observations at 42 sites finding 37 active and documenting 2,045,652 Vaux’s Swifts going to roost. Got a couple hundred thousand more in Mexico but a lot of those were probably not migrating. 

This is only our second time over two million and there were some happenings worth pointing out.

1. We picked up a big number tree roost in the Olympic National Park.
2. JBLM was all but abandoned.
3. World famous Portland Chapman was totally abandoned in mid-September.
4. The North San Francisco Bay Brickyard had its second migration over a million.
5. Got a bit more data confirming we have located the worlds most significant Vaux’s Swift roost site south of Mexico City.
