When I was in Moss Landing recently, I knew it would be a good opportunity to photograph snowy plovers in the sand, because they nest along the beach at the mouth of the harbor. Snowy plovers nest right in the open sand, which is why their nesting grounds are frequently protected along the California coast. It was still a little too early to see established nest sites, but they should be scoping some out.

After some searching, I found a few of them sitting down in the sand. They were just starting to come into breeding plumage. Not wanting to disturb them, I spend a good ten minutes creeping slowly closer, until I could create frame-filling shots like the one above. My tripod legs were fully splayed out in order to get the lens closer to the ground. I was pretty happy with my position and the fact that I had gotten as close as I needed to without disrupting the birds.

After making some shots, I looked up and saw a surfer emerge from the water a little ways up the beach. I thought he would continue walking toward the road, but then he saw me and starting walking in my direction. Unbelievably, he walked directly toward me fully in my lens’s line of sight. And he didn’t stop until he was standing next to me looking down at my prone form! Needless to see, the birds scattered as he tromped through their would-be nesting area. I was just staring at him (probably with a dropped jaw), incredulous that he would have so little common sense or self awareness.

“Getting some good photographs?” he asked.

“Well, I was,” I relied wryly. As the acclaimed bird photographer Art Morris is fond of saying, you gotta love it!

The scattered plovers were not to be refound, and I had to settle for the photos I already had. However, I spent some more time creeping up on some sanderlings and western sandpipers who were busy poking through shells and seaweed that had been washed up on the beach. These photos can be seen below.

I quick word to the non-photographers out there. If you are in a remote area and see someone concentrating on something with their camera, please please please don’t just walk up to them and interrupt without understanding what they’re photographing. This is especially important with wildlife that you can spook. The photographers of the world thank you.

Breeding American Avocets

Spring is in the air, and so is the reproductive instinct of many local bird species. I had the opportunity recently to photograph an American avocet pair copulating, and was able to record the interesting mating dance that occurred immediately afterward. Remaining monogamous throughout the breeding season, this pair will soon likely select a local nest site, or migrate north to nest (avocets are both migratory and year-round residents of the SF bay area).

As they begin, the female signals to the male that she’s ready by standing alert with her head low and forward, close to the water. The male stands next to his mate, or directly behind her.

In one quick motion, the males jumps up onto the female’s back. Breeding only lasts a few seconds, during which time the male flaps his wings repeatedly. Just as quickly, he jumps down again.

Immediately after copulation, the avocets cross beaks. Holding them in this position, they walk in a tight circle two or three times.

Immediately after copulation, the avocets turn toward each other and cross beaks. Each bill rests against the other’s neck, with the male standing slightly taller than the female. Holding this position, they walk in several tight circles.

Once the circles are completed, they march off together side-by-side. I always find it fascinating to watch these intricate rituals that have developed over thousands of years.

Mandarin Duck (Photo of the week)

I photographed this Mandarin duck today at a city park in San Jose. This is a very strange location for this species, as it is most often found in Asia. After speaking to some of the locals who visit the park often, I learned that this drake has been seen on and off at the lake over the last three years.

The Mandarin duck once flourished across eastern Asia, but today there are only about 1000 pairs throughout all of China, and about 1000 pairs in Russia. Japan is thought to have about 5000 pairs. They have also appeared in various locations in Europe, numbering about 1000 pairs in total. Because this species is not native to Europe, it is surmised that this population grew from escaped captive birds and flourished as a feral population. They have been breeding in the wild ever since. But where did this guy come from?

It turns out that something similar to what happened in Europe may have also happened in Sonoma, California, only on a much smaller scale. Sonoma is a couple hours drive north from San Jose, and has about 100 feral Mandarin ducks. I’m just guessing here, but this bird may be associated with that population. And apparently he enjoys coming to this lake!

It was fairly overcast today, which has its advantages and disadvantages for bird photography. One of the downsides is that the sky is much darker, which means that shutter speeds must be slower than on a sunny day. However, benefits include a lack of harsh shadows from the sun (meaning I could photograph this bird from any angle, instead of with the sun directly behind me), and more saturated colors due to reduced glare. I was very happy to be able to photograph this species in decent conditions. The biggest bonus of course was that I only had to drive half an hour instead of flying to Asia or Europe!

Greater Yellowlegs (Photo of the week)

The photo this week features the greater yellowlegs. They are somewhat common in the Bay area throughout the winter, usually seen in ones or twos. On this day, I came across two yellowlegs foraging with a willet in a shallow, narrow slough. It was late afternoon and the sun was just starting to reach the horizon, so I knew I didn’t have much light left in which to shoot. Unfortunately, all three were in the deep shadow of the high bank of the slough, so I wasn’t getting that sweet sunset light that I was after.

Just then a runner appeared on the trail paralleling the slough, and decided to stop and watch these birds. Once he stopped, all three flushed and flew a hundred yards north to a spot where the bank lowered and the slough opened up. Lucky me! For once, I benefited from someone chasing away the birds I was photographing. I quickly (and much more carefully than the runner) repositioned myself to their new location, very happy to see that all three birds were now bathed in golden light. I had less than a minute of these lighting conditions before the sun finally dipped below the mountains.
