A bird on the face of the Moon, October 9, 2014

Early in the morning of October 9, about eighteen hours after I had photographed that morning's Lunar eclipse, I went out to get photos of the just-past-Full Moon.

I prefer to use a manual setting when I take pictures of the Moon when it is close to Full. The manual setting takes sixty frames per second and creates images that are a bit dim compared to the automatic setting. This reduces the blinding glare of the Moon and allows subtle details that would otherwise be washed out to be visible.Unfortunately, it also puts the camera into a "widescreen" mode that reduces the overall image area to something that some of this Summer's "Super Moons" haven't been able to fit in. So it's very easy to cut off the top or bottom of the Moon in a standard landscape photo.

I was interested in capturing the subtle and not-so-subtle differences in the shadowed regions (on the right in these photos.) I set up the shot as best I could, centered it as well as I could, set the ten second timer, pressed the button, stepped away -  and watched with annoyance as the image on the screen showed that the Moon had slipped slightly out of the frame.

I also noticed something else - a speck that appeared after about five images, moved across the face of the Moon, and disappeared halfway through the shot.

I had captured a bird crossing the face of the Moon.


The Moon is big, really big. But it's quite small in the sky. Even in its extra large "Super Moon" state it still appears barely larger than an aspirin or the eraser at the end of a pencil held at arm's length. Now, look at how small that bird appears against the face of the Moon, and imagine how incredibly tiny it appeared in the sky. And yet I caught it as it flew between me and the Moon!


Photos of birds crossing the face of the Moon are not uncommon, which tells you something about just how many birds there are flying around at night. Still, the odds of getting one crossing your shot as you take pictures of the Moon seem...well, literally astronomical.


This bird appeared in twenty-six of the sixty images in that burst of photos. In most of them it isn't doing anything very interesting. In fact, it seems to be dropping like a rock with its wings either edge-on to the camera or completely folded back against its body. Starting with the first image and ending with the third image above, here is every third image in the sequence. (No wing flapping is apparent between any of these images.)
