A few days later, I found myself with no lunch plans and no leftovers in the office fridge, so I hopped in the truck and headed back out in search of the swallows. Sure enough, I found two colonies of Cliff Swallows nesting under the highway bridges.
Cliff Swallows (Petrochelidon pyrrhonota)
There were dozens of adobe-looking nests plastered to the concrete wall of the freeway overpasses, high rise rooms with a view. Some were obviously new and intact, others appeared to be refurbished models with a cracked edge or two, and still others were just the old broken shells of abandoned nests from years past.
Almost all of the intact nests seemed to be occupied, with some swallows sitting alertly inside watching the nonstop comings and goings of the other birds. At any given time, there seemed to be at least two or three dozen swallows in the air around each colony, performing acrobatic feats of flight that left me dizzy every time I tried to follow them with my lens.
I haven't had a chance to return in the three weeks since I first visited these colonies, so I don't know if there are babies in the nests now or if they've already fledged and moved on, but I sure enjoyed the half hour or so that I got to spend watching their frenetic activities.
As always, you can click on any of these images to view them on Flickr, and then click the "All Sizes" button above the image to see the larger versions.
