Last night the Monroe Wagner roost site had 2000 guests. Joint Base
Lewis McChord added 3000 to bring its 2012 Southbound roosting event
total up to 206,617.

The center of the swift migration this week seems to be San Francisco,
where the McNear Brick plant has been having 19,000 a night.

Currently will give you a look at three swifts that came back to the
Wagner chimney after their very early 6:45 exit.
