I recently found this savannah sparrow out in the open, pecking away at the ground for food. These sparrows are not as common in my area as the prolific white and golden-crowned sparrows. Savannah sparrows actually derive their name from Savannah, Georgia, where they were first classified.
That day, there were dark storm clouds in the sky and the light was very low. Only after taking several shots of this sparrow did I realize that I was still using ISO 400 (my typical starting point for bird photography), which lowered my shutter speed to only 1/125 sec. With an 800 mm lens, that is a bit too slow for comfort (even with a sturdy tripod). Anything slower than 1/250 sec introduces a real risk of camera shake, leading to a blurry photo. It is a true testament to Canon’s 4-stop lens image stabilization that I was able to pull these shots off, and with remarkable sharpness. If I had been paying better attention, I would have bumped my ISO to 800 (even though this would lead to more digital noise in the resulting photo), and thus halved my shutter speed.
Spring is almost here, and with it comes the showmanship and fortitude of male birds courting their females. Especially fun to watch are the common goldeneyes, with their neck stretches, head throws and incessant quacking – all in the pursuit of charming that special someone who, if the performance is good enough, might return the affection. I took all the shots seen here recently at Shoreline Lake in Mountain View, where a multitude of common goldeneye can be seen putting on their show. If you live nearby, I definitely recommend a trip there either in the early morning or late afternoon, when the birds are most active.
The common goldeneye courtship display consists of several different maneuvers. The most common move seems to be the neck stretch, which can be seen in the photo above, and the photo immediately following.
If he wants to get a little flashier, he shoots his head straight up with a long neck and lets out a loud quack. Sometimes this first and second move are done in sequence, with the bird first poking his head out in front, and with the neck extended, swiveling it straight up to quack. This usually gets the ladies attention.
If that doesn’t quite do it, or the goldeneye is feeling particularly frisky, he pulls out the head tuck move. Here he folds himself backward in half, touches his head to his back and lets out a kind of double-quack. It seems as though the first quack actually comes in normal position, followed the the quick head throw and second quack up into the air. This second sound is louder and more drawn out than the first, kind of like putting the accent on the second syllable of a two-syllable word.
Finally, if nothing else is working, the goldeneye busts out the uber-display. After performing the double-quack with his head tucked against his back, he forcefully kicks both feet backward, splashing water high into the air. I only saw this display a few times by only two birds – each of the other displays were more common.
If all goes well, he finally attracts his mate, who shows the love by mirroring some of his moves. In the following photo, the male is being followed by an interested female.
Courtship displays of different avian species can be fascinating to watch, and can get quite elaborate. Personally, I think I’ll stick to chocolate and flowers!
This week’s photo features a brown pelican fishing. What impressed me about this photos is just how big the pelican’s throat pouch balloons underwater. Often we just see the head as it comes up full of water (and hopefully fish), but here we can see the bill before any water starts to drain. Brown pelicans often dive for their food, whereas other pelican species prefer to scoop prey just below the surface of the water. Once the bill is above water, it must drain before the pelican can swallow what’s left over. During this time, fish can sometimes be seen jumping out of the throat pouch for freedom. In addition, other birds sometimes take this opportunity to steal fish out of the pelican’s mouth.
I’m a sucker for a photo with a perfect background, and that’s what sets this week’s photo apart for me. I usually try not to include man-made objects in my wildlife photography, but in this case, I thought the old rusty pump wheel juxtaposed against the smooth white feathers of the egret added to this photo. And there’s that background! Smooth green, with just enough abstract shapes to hint at lush vegetation. Yes, I know it’s another egret shot, but why not? After all, they are a pretty photogenic bird.
Because I wanted to make sure that both the egret’s face and its back were in sharp focus, I stopped down to f/8. I knew that the background was far enough away to still render out of focus. As I often do with stationary birds, I used only the center focus point on the egret’s eye, then recomposed while holding the shutter button half way. This ensured that if I didn’t stop down the aperture enough to include both the back and face in focus, at least it would be the eye that had the sharpest focus. If the eye isn’t in focus, the shot goes in the trash.
This photo was taken on a very overcast day, so I didn’t have to worry about the sun angle. The shadows would be soft and even, without bringing in too much contrast. Therefore I positioned myself according to the nicest background I could find. This had the egret facing away from me, so I had to wait until its head came into view, and was at least parallel to the sensor plane, or pointed slightly toward me. No one wants to see a photo of just an egret’s back. I made a noise, prompting the egret to swing its head and neck around to look back over its shoulder. That was it – I knew I had the shot!
