Evening Grosbeaks

I recently finished processing a series of photos I took of a flock of evening grosbeaks that invaded a neighborhood in Sunnyvale, CA, a little south of my home. For several days, the birds were repeating a pattern of flying into the area in the morning, and perching on a row of chinese pistache trees, so I decided to head down and see if I could locate the flock.

I arrived in the neighborhood just after dawn when I figured the birds would be busy eating. I began to walk up and down the streets, occasionally stopping to listen for the distinct crunching sound of the birds eating the fruit off of the trees. All the while I was under the watchful eyes of the residents, who probably don’t often see someone walking past their house with an 800mm lens mounted to a large tripod.

Finally, I was on the verge of giving up and decided to make my way back to my car. On my way back, I passed under one of the many chinese pistache trees and heard the soft crunch crunch crunch. Looking up I could just see one or two of the grosbeaks in the upper most branches. Thrilled, I set up my gear on the sunny side of the tree (so that the birds would be front lit), and waited until some of them ventured to lower fruit.

In all I hung out for about 20 minutes before the birds lifted off and flew elsewhere. It is always a treat to get such opportunities to photograph seasonal migrants.

Pelican Palooza

I stopped at one of my local spots to photograph birds and was rewarded with an abundance of not only one pelican species, but both species that are regularly seen in California – the American White Pelican and the Brown Pelican. Usually I don’t see both in one area, but here they were at Shoreline Park in Mountain View, each doing their own thing.

First, I saw a half dozen white pelicans swimming together, and fishing simply by dunking their heads underwater and scooping up great billfuls of water. In this way, they were able to catch small fish, but on a fairly regular basis.

Most of the time, at least one pelican would remain above water while the rest would go for fish. They would rotate this way, dunking, scooping and eating. At some points however, I saw all pelicans in the group go under at the same time. I waited to see if I could get them lined up, and finally I saw a moment of symmetry in order to capture this photo.

Next it was on to the brown pelicans, who were circling above Shoreline Lake, and going through much more effort to fish. A pelican would circle for a while, keeping a close view of the surface of the water.

When it saw a movement of fish in the lake below, it would stop its forward flight and sort of hover in air.

At this point, it would plummet to the water surface in a dive, completely submerging its entire body underwater. The success rate of fishing this way seemed lower than the white pelicans, but perhaps when the diving did work, it rewarded them with bigger fish. It was fine by me, because their activity rewarded me with many flight shots and photographs of the birds on the surface of the water.

After a dive, the pelican would drain its bill of water, and swallowing any fish it caught. Occasionally, I was rewarded with a vigorous head throw.

After a couple of hours of shooting, I was pretty pelican’ed out and I packed up to leave. But it was great to see both species side by side on a single morning.

Going Macro With A Big Lens

Don’t get me wrong – I love my big lens. My primary lens for bird photography is the Canon 800mm, which serves as a real workhorse. However, there are times while using that lens that I get frustrated. One of the lens’ limiting factors is its minimum focus distance. I can’t bring any subject closer than 16 feet into focus, which means that very small things (for example, hummingbirds) still appear fairly small in frame. What to do about this limitation? Enter the extension tube!

Recently I took an out of town colleague to some of my favorite local bird sites. We found an area rife with anna’s hummingbirds, zipping this way and that, and generally causing a ruckus as they battled each other over territory. I took some shots, but couldn’t get close enough to these little creatures to fill the frame. I resolved to come back the following day, this time armed with my full array of extension tubes.

Luckily the hummingbirds were still there, sparring and resting, and this time in beautiful light. I wanted to get as close as possible, so I stacked three tubes together and placed them in between my camera body and lens. This allowed me to get as close as about 10-12 feet away from the birds, finally filling my frame. Creeping closer yet, I wanted to push my extension tubes to their limit, and was able to get the image below.

Extension tubes have no optics in them, and can even be in the form of cardboard – no electronics required! My tubes happen to have small contacts that still allow me to use my lens’ autofocus system, albeit much slower than normal.

The principal of an extension tube is to move the rear focusing element of the lens further away from the focal point, which in today’s world means the camera’s digital sensor. The effect is that the lens’ minimum focus distance is reduced, allowing the entire rig to move closer to the subject while keeping it in focus. The downside is that with extension tubes attached, the lens will no longer be able to focus to infinity.

In comparison to most photography gear, extension tubes are relatively cheap. I have a set of Kenko tubes that stack together. If you ever want to dabble in macro photography, I recommend first getting a (cheap) set to tubes before spending bigger bucks on dedicated macro lens. Yes, the macro lens will give you better quality, but a set of extension tubes will allow you to bring your entire collection of lenses into the macro world.
