Warning!

MAY BE UNSUITABLE FOR IMPRESSIONABLE MINDS.

Well, there's nothing really unsuitable for any audience here. This is a sequence of photos of White-throated Swifts engaged in aerial copulation. They are well-known for their mid-air mating. This is not necessarily an easy activity to observe, but if you find an area where these swifts congregate near a possible nesting area around mid-May, you just might get to see this. They appear to tumble downward while they are engaged as neither can flap enough or maintain a proper airfoil to fly horizontally. In these shots, they seem to be doing a perfect rendition of dual skydivers.

The taxonomic order that swifts occupy is named Apodiformes, which translates into "without feet", because their tiny feet were not often seen. It's interesting to see that in the photos where the swifts are close to each other, their feet are quite obvious.

These photos were captured with a lot of luck, and flying swifts, at Pinnacles National Monument on May 15, 2005. Their flights up the canyon along the trail to the Bear Gulch Reservoir from the Visitor Center on the east side were easy to observe as they were close to eye-level and sometimes below the trail. I saw one swift carrying nesting material into a fissure in a large spire near the dam at the reservoir.
