Black Tern, Boulder county

[Maureen Blackford]

There are currently (May 22nd, 1:00pm) approximately 7 black terns at Sombrero marsh in Boulder County. They are flying with about 150 swallows, predominantly over the south west corner of the pond. They occasionally land on PVC pipe that sticks up from the pond (closer to south end)

Sombrero Marsh is one block south of Arapahoe & 63rd St in Boulder. Turn south from Arapahoe St on 63rd St.

Wow, what a show --- thanks for sharing this!   At 2:30 PM we saw the 7 terns with accompanying swallows.  Then watched a very dramatic swarm of many hundreds of swallows drifting north, really filling the sky from just overhead to hundreds of feet in altitude.
