Barrow’s Goldeneye (Photo of the week)

This week’s photo features a Barrow’s goldeneye. The Barrow’s is similar to the common goldeneye, but, as its counterpart’s name suggests, is less “common”. In fact, only a few are seen in the San Francisco Bay Area each winter, whereas the common goldeneye can number in the thousands (with dozens visible at one time).

While both male species look similar, the Barrow’s goldeneye has several distinguishing features. The two most prominent are an elongated teardrop shaped white area in front of the eye (the common has a smaller circular white patch) and a row of white squares across the base of the wings (which can be seen across the top of the back in the photo above).

When I found this male, I was lucky enough to find a female with him (which I assume made up a breeding pair).

Female Barrow’s goldeneye look more similar to the female common goldeneye. The biggest difference is a completely yellow bill (as above), compared with a yellow-tipped black bill on the common. Other than that, they look identical (to my eye).

I saw this pair on several occasions, as they frequented the same spot for a couple of weeks at least. On one occasion, I began to worry for the female, because I saw the male swimming with a would-be harem of twelve female common goldeneyes. There were no male commons in sight. These two species have been known to crossbreed, but I’m not sure exactly what was going on in this situation. Perhaps it was because he was the only male of either species around, or perhaps it was just because he is much cooler looking with his bold white square pattern. The next time I saw them however, his lady was back at her top spot, and the other females has moved on to more common mates.

Hooded Merganser

I was lucky enough to find a pair of hooded merganser a few weeks ago at a local birding spot close to my house. While not uncommon to the area this time of year, they are usually seen in very small numbers – usually only in ones and twos. I found this attractive pair in a narrow channel that is usually very shallow, but had recently flooded, providing enough depth for these diving birds.

As I approached, I crouched down and worked my way toward a large clump of tall grass along the channel that could provide some screening. I crept up behind the grass and set up, careful to work very slowly so as not to disturb the pair. The last thing I’d want is for them to fly somewhere else – they seemed to be set up in the perfect position for me. The rising sun was behind me, casting the birds in full frontal lighting, and the channel was narrow enough that the entire surface of the water reflected the straw colors of the opposite shore.

After I set up, I knelt behind my tripod in the mud and goose poop (I often wear knee pads when I expect to shoot at water level) and poked my lens through the grass. They seemed right at home with me there, giving me a full half hour with them as they swam back and forth in front of my camera.

During courtship displays, the male fans his crest open, as seen in the first photo. The male seen here had a flat crest most of the time, only displaying his crest once to ward off a curious cormorant, and once while scratching the back of his head with his foot. The female seemed to display her crest most of the time I was watching them. The photo below shows the male with a flattened crest.

Like other mergansers, the hooded merganser has a long thin bill with serrated edges. This helps to grip fish and crustaceans when the birds dive underwater for them. Because of this trait, mergansers are often called “sawbills”. They are a somewhat secretive bird, nesting in small tree cavities hidden away from would-be predators. Hunting underwater by sight, they can actually change the refractive properties of their eyes in order to enhance their underwater vision.

After a while, the mergansers decided they were done with this water channel and it was time to head off to more fertile fishing grounds. I was elated to have had that time with them, in such good photo conditions.

Sleeping Green-winged Teal (Photo of the week)

This week’s photo is of a sleeping green-winged teal, as he floated around a local pond along the bay. The green-winged teal is one of the many duck species that winter here, extending the color palette from the ubiquitous mallard. I liked this photo because of its simplicity, and the vivid colors reflected in the water.

Many days I am up at dawn photographing, just for moments like this. Not only is the light warm and slanting in low across the horizon, but water tends to be still and glassy, offering many opportunities for great reflections.

American White Pelican Takeoff (Photo of the week)

A couple of weeks ago I visited Byxbee Park in Palo Alto, just before sunset. I wanted to explore a slough I had never been down before, and was lucky to see eight American White Pelicans, all swimming together and fishing. The first photo and the next were shot as part of the same sequence of one of them taking off from the water.

You can clearly see a flat horn protruding from the top of the bill. This indicates that this pelican is breeding. After breeding season, the horn will shed off, leaving the bill as it was before.

Usually I try to frame birds with most of the photo empty in front of the bird. This creates a more pleasing composition as it seems to add more room to the photograph. It allows the viewer to visualize the bird moving through the photo. With the above photo however, I knew at takeoff, the pelican would leave behind splashes as it took off into the air. I wanted to capture these in the photo, so I panned slightly slower than the bird was moving so that in this case, most of the empty space was behind the bird.

Below are several other pelicans from the same group. As I was watching one fish, he lifted his bill into a magnificent head throw.
