When it comes to aerial skills, Tree Swallows (Tachycineta bicolor) are some of the most agile fliers that I have ever observed. On Monday I watched in awe and amazement as a small group of tree swallows swooped and zoomed over the waters off of Occoquan Bay National Wildlife Refuge. The flight of these tiny birds was graceful and mesmerizing, full of acrobatic twists and turns.
It was a real challenge, though, to take photos of birds that are so small and so fast. I was especially happy when I managed to capture the first image that shows a pair of swallows with their wings fully extended. The second shot shows a swallow gliding low over the water—the shape of the bird reminds me of a stealth aircraft skimming low over the earth to avoid being detected by radar.
I did not realize that Tree Swallows had returned to our area. There are several nesting boxes at this wildlife refuge that Tree Swallows regularly use, so I will have to check them out soon. Sometimes there is a competition between Tree Swallows and Eastern Bluebirds for the nesting boxes. I am not sure how they decide who will get to use the boxes, but somehow they figure it out.

Another swallow confrontation

Are Barn Swallows normally hostile toward each other?
As I was looking over once more the shots that I took on Monday, I came across this little series of images of two Barn Swallows (Hirundo rustica) interacting. I had passed over these photos when I did my first sorting, because they were seriously underexposed. Unlike the photo that I posted earlier this week of a confrontation between two swallows, I was not using a flash for these photos, which meant, however, that I was able to take a burst of photos. (When I used my pop-up flash, I had to wait for the flash to re-cycle in order to shoot again.)
I tweaked these photos in Photoshop Elements (and cleaned up the background a little) and was amazed to discover that this confrontation seems to have escalated a bit beyond the previous one. The flying swallow seems much more aggressive and threatening, going beyond the squawking I had seen before, and looking more like he was ready to attack the sitting swallow, who seems to be paying attention to the incoming bird.
These photos would have been better with a higher shutter speed and better light, but I am amazed that I was able to capture this moment. I love interactions between members of the same species (and between different species) and I enjoy trying to catch those moments.
