Earlier this month I was happy to get some nice views of a wintering palm warbler, while photographing in the city of Redwood Shores, CA. This is a somewhat uncommon bird for this area, so I was excited when I confirmed the sighting after further research. My view was unobstructed and the lighting perfect – about an hour after sunrise with the low, winter sun directly behind me.

I shot quickly and furiously, trying to capture as many poses as possible before the bird flew off. I ended up with about 45 seconds of time before the little guy decided he’d had enough with the paparazzi. The following photos were taken at the same time, in the same tree. Thank God for 8 frames per second!

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.

Anna’s Hummingbird (Photo of the week)

This week’s photo features an anna’s hummingbird that frequents my front yard. Her favorite perch is the top of a cherry tree, offering her an expansive view of her surroundings. Hummingbirds can be very territorial – I have seen brief squabbles that have sent the loser zooming away to find flowers elsewhere.

These shots were all taken hand held with the Canon 7D and the 100-400mm f/4.5-5.6L IS lens. Although this lens has been available on the market for a long time, it is still a great walking around lens (for wildlife anyway), and is a great asset for birds-in-flight shots. With zoom capability, it is much easier to find and track subjects in air than with longer lenses.

Lunar eclipse, December 20, 2010

Last night I stayed up late to photograph the lunar eclipse from my front patio. While not the best of locations as far as light pollution goes, it doesn’t matter that much for moon photography, given the moon casts off so much reflected light. I started photographing just before 11pm, as the earth’s shadow was just touching the outer edge of the moon. The progression was as follows:

The eclipse begins
The eclipse begins
The earth's shadow moves across the moon
The earth's shadow moves across the moon
The earth's shadow consumes more than half of the moon
The earth's shadow consumes more than half of the moon
The moon reflects a dull red from the shadow of the earth

The last photo was taken at the peak of the eclipse, with the sun and the moon on exact opposite sides of the earth. To understand why the moon glows red when fully in the earth’s shadow, it is easier to think of what the earth would look like from the moon. From the moon’s perspective, at the peak of the eclipse, the earth would be ringed with red outline of the sun. It would be like watching all sunrises and sunsets all across the planet, all at the same time. This red wavelength is cast by the earth’s atmosphere into the earth’s shadow (the center of the silhouetted earth, ringed by the sun), which is then reflected by the moon back to us as a dull red glow. It was definitely a cool phenomenon to witness and photograph.
