If you've been following this blog for the past few years, you'll know that we're completely fired up about Vaux's Swifts. In particular, we've been completely enthusiastic about their fall roosting in downtown Los Angeles. While the northward migration of these bird in the spring tends to be a little more dissipated than the spectacular displays we see in the fall, it is still great to see the birds come through. For the last couple of weeks, Jeff Chapman, director of the Audubon Center at Debs Park in northeast Los Angeles, has been tracking the birds in downtown Los Angeles. He's seeing fewer of the birds now, although he was able to snap the photo of the birds swarming over downtown below the fold. For the most part, the bulk of the birds seem to have moved north, as this great video from Eugene, Oregon, posted just a couple days ago, seems to show.
