Western Sandpiper In Breeding Plumage

A little while ago I headed out to the edge of the bay to check out some of the shorebirds making their way down south for the winter. I found quite a mixture of species, and because of the busyness of the birds, I was able to creep quite close to them without notice. Suddenly I found myself face to face with one of the tiniest of the peeps – the western sandpiper. While very common, I had never been so close, and had never seen breeding plumage quite so vibrant.

I snapped away, going for shots of many sandpipers crowded together, and also trying to single them out and find compositions with as few distractions as possible. For the shot above, I knew I couldn’t hold focus for all the birds front to back with my long lens, so I picked one bird for critical focus, and then used the rule of thirds to position him well in the frame. I liked the result – a sandpiper’s head in sharp focus, surrounded by a pattern of feathers and colors.

Singling out individual birds was more difficult. Each time one would wander away from the rest, other shore birds would quickly move in front of and behind the bird. In addition, these little guys move quite fast while eating, so much of the action was captured in a run-and-gun style, hoping for the best. It was definitely one of those moments that made me appreciate digital – had I tried that with film I would have soon been broke (not to mention reloading film in the middle of the action)!

Even though this is a very common species, I was happy with the lighting and the close proximity. Sometimes the most common birds get left out of all the fun!

Amorous Eareds

Recently when I lucked out by capturing four different grebe species in one day at Shoreline Lake in Mountain View, I witnessed something new for me – two eared grebes who had paired up for season were not only showcasing their courtship behavior, but were also mating. I was surprised to see this because usually the grebes head north for the summer before mating, and as a result I had never seen this behavior before.

Their courtship seemed to have several stages of intimacy. First, they swam close to each other across the lake as seen above. Suddenly, they would run side by side across the surface of the water (essentially flying very low over the water) and quickly make it to shore, only to turn around and swim slowly back to their starting location.

Part of the eared grebes courtship display is to fly low across the surface of the water together. Once they land nearby, they swim back to their starting location, and proceed to mimic each other. They repeat this cycle of mimicking and flying together until they (usually) mate.

Occasionally, they would attract the attention of an unexpected guest in their over water flight.

Once they had performed this flight several times, they stayed out toward the middle of the water and proceeded to mimic each other, a behavior seen frequently in other grebe courtship displays.

After satisfactorily copying one another, there was no putting off the inevitable. It was time to seal the deal.

As I said before, I was surprised to see actual mating behavior. I have not heard of eared grebes successfully nesting in the area, so I assume this couple soon headed north for a more traditional breeding season together.

Grebes Galore

Lately I’ve been going through my backlog of unprocessed photos, and I happened upon a collection I took one day at Shoreline Lake in Mountain View. A theme of “grebes” jumped out at me right away, as I had captured on camera four of the five common grebe species in the SF Bay Area, within just a few hundred yards of each other, and all in their breeding plumage.

First up were the beautiful eared grebe (above) and the horned grebe (below). At the peak of their breeding plumage, they are quite easy to differentiate, but in their winter colors, it takes a sharp eye to tell the species apart.

As usual, the eared grebes greatly outnumbered the horned grebes, but both species were mingling and fishing together quite happily.

Closer to shore in a sheltered corner of the lake were several pied-billed grebes. While the eared and horned grebes usually migrate north to breed and raise young, many pied-billed grebes raise their chicks in the Bay Area. When they enter their breeding colors, they gain a thick black band around their bill. In the winter, the bill is a solid bone white color.

Finally, a clark’s grebe made a brief appearance in the lake, most of which seemed to be under water. Clark’s grebes look similar to the region’s last common grebe, the western grebe. Clark’s grebes also migrate north to mate, however a persistent couple has been trying to raise young over the last few years in another location within Shoreline Park. So far, they have been unsuccessful, with either no chick hatching at all, or the newly hatched young dying within days. A successful nesting would be of great interest to the local birding community, as many have kept watch over this pair’s nest over the last couple of years.

I was happy at the variety of grebes that day, and that I caught some of these species at just the right time: after they had molted into breeding colors but before the left for their journey north.

Snowy Egret In Breeding Plumage

Looking back through my archives, I came across these photos of a snowy egret in full breeding plumage. Because there are so many of these birds around my home, I often overlook them (everything ends up looking like a crow after awhile). But these photos stood out as they were taken at the height of breeding season, and this bird in particular had magnificent breeding colors.

As snowy egrets enter breeding season, their feathers become long and shaggy. When the they display, they can create a great fan of feathers with which to show off. In addition, a hormone in the body changes the pigment of their skin around the eye to a bright red.

Seeing these photos reminded me that birds are a living and breathing part of the natural world around us. Like much of nature, they change colors and shapes as the seasons change, and are constantly adapting to their environment.
