Ross’s Geese, Winter Sky

February 18, 2012 G Dan Mitchell Leave a comment

A group of Ross’s geese in flight against a winter sky above California’s Central Valley.

I may have mentioned before that I’m not the world best namer of things – I struggle with identification of both flora and fauna, at least beyond the most obvious stuff. This is somewhat odd, since I often recall and recognize in great detail the specific characteristics of things. For example, while I’ve never been able to consistently remember the names of certain wildflowers, I’m very familiar with them and can tell you exactly where to find the plants, when they bloom, and so forth. This is all my preamble to saying that I’m pretty sure these are Ross’s Geese, but that I make no guarantees! From a bit of reading and viewing I did before posting, I found out that telling the Ross’s Goose apart from the Snow Goose is not an easy thing. Some of the differences are more of degree than anything else – one is a bit larger and has a bit larger wingspan. Others are subtle, for example the head shapes. Some or more obvious, such as the presence or not of a certain pattern on the side of the bill. (I now know that some other birds that I had not identified earlier on must be Snow Geese… since I now recall seeing that very pattern and wondering about it.)

Anyway… when we visited the Merced National Wildlife Refuge on an early February evening we got lucky and found a huge mass of these birds (and others) in a location that was fairly close to the places from which viewing was possible. To give you an idea of how many birds there were, when we first arrived we noticed groups of a few hundred lifting off and flying away and began to worry that we might miss the show – but it turned out that a few hundred departures, repeated many times over, did not diminish the apparent size of the monumental group of birds at all!

For me, and I suspect for most who photograph these birds, the “hit rate” is something considerably short of 100%. If I have to wait long enough for birds to fly over, eventually I get impatient and start shooting groups that are really too far away to make good photos. Others look like they are heading my direction, so I compose and start shooting, only to watch them veer off to the side. Others approach close enough but they end up against bright sky and little or no detail is visible in the shot. Others come close but assume odd positions that don’t make impressive photographs, or they may even come too close to photograph! But eventually, something good happens. This group came close, flew towards me, and within shooting distance not only turned to present great profiles but even lined up in such a way that the low sun caught their undersides and filled in what might have been silhouettes otherwise.

Two Owls, Trees and Ponds, Dusk

February 14, 2012 G Dan Mitchell 2 Comments

Two owls in the branches of a group of trees at dusk, reflected in the waters of a pond at the Merced National Wildlife Refuge.

I originally posted this in an impromptu manner and out of sequence back on SuperB owl Sunday – but now it comes up “officially” in the queue. At the very end of a winter day that had begun well before dawn back up the Central Valley closer to Sacramento (in the Cosumnes River area, to be precise) we had headed south to Merced National Wildlife Refuge in search of somewhat different subject for the evening. We arrived to find some geese on the pond, but most were a bit too far off for good photography. But while we settled in to wait for whatever else might show up, I turned my attention to the beautiful and wide-open Central Valley landscape.

This little group of trees grows on a small levee between a couple of ponds in this agricultural area. (Over the past few weeks I have come to know this exact spot very well, as I have been back three times now to photograph there, with better and better luck each time.) After the sun set, some of the most beautiful light appeared – the soft and pink/purple/blue atmospheric light of dusk, when there is still some brighter color in the sky. I saw a single bird high in one of the branches of this tree and soon figured out it was an owl. I set up a composition that centered the tree – creating, I hope, a sense of quiet and stillness – and which included a bit of the sky and the beautiful reflection of the tree’s silhouette in the water. As I shot, a second owl showed up for a few seconds and I was able to get a frame with the couple together.

Migratory Birds in Twilight, Central Valley

February 13, 2012 G Dan Mitchell 3 Comments

Migratory birds flly though the twillight winter sky above California’s Central Valley and the Coast Range.

I made this photograph when it was almost too dark to see clearly. In fact, when I packed up and drove away a few minutes later, it was so dark that I momentarily got mildly lost on my way out of the refuge! Long after the sun had set, and at the time when perhaps the most intense sky colors appear, the migratory birds were still in flight above the Central Valley, often silhouetted against the colorful dusk sky just above the horizon.

This photograph is going to get a bit more technical explanation than usual. I had a 100-400mm telephoto on the camera at this point since I had been photographing the birds in a variety of ways, including trying to fill the frame with one or a few birds. While some might say that shooting a prime lens of this length could have some image quality advantages, this photograph wouldn’t have happened if I had been shooting, say, a 400mm prime. Since I wanted to move quickly from targeting small sections of the surroundings or even individual birds to making photographs that attempt to portray the larger landscape within which the birds are found, I frequently found myself moving quickly to much shorter focal lengths. Here, I realized that I might be able to “zoom out” and include some of the birds in flight high above the valley and the distant mountains in the context of their surroundings. So I shot this at something like 130mm. In addition, because the scene includes subjects that are not that far away (like the trees) and those at much greater distances (like the hills), depth of field was an issue with the longer focal lengths. I couldn’t shoot wide open without some excessive focus issues, so I stopped down to f/11. Think about that for a moment: shooting in extremely low light, stopped down to try to maintain some depth of field… and needing use a shutter speed allowing me to get some definition out of birds flying through the scene. This is essentially being caught between a rock and a hard place… and another rock. With the camera on the tripod, but still aimed manually, I used a shutter speed of 1/13 second and turned image-stabilization on. With all of this stuff pushing boundaries of shutter speed and aperture… my only option was to increase the ISO to 1600. For landscape work. Here’s the thing… in the end, while there was more noise in this photograph than if ISO 100 were possible, it isn’t that bad and probably wouldn’t even be visible to viewers of a print. While I’m usually persistent in my view that little technical differences among cameras don’t amount to much, in this case it was because current cameras make it possible to shoot in ways that were essentially impossible a decade ago that I could get this photograph at all.

Ross’s Geese, Winter Evening

February 12, 2012 G Dan Mitchell Leave a comment

Motion-blurred photograph of low-flying Ross’s geese on a winter evening in California’s Central Valley.

From time to time I experiment with longer exposure photographs of birds in flight. The idea is that allowing the image to blur as the birds move might suggest their constant motion more effectively than the more typical approach of stopping the motion. Here not only was the exposure relatively long (I think it was 1/30 second) but I was shooting with a long telephoto which also amplifies the motion of subject and camera.

I’m thinking of this as a “study” for future photographs of these Ross’s geese and similar birds that will work with this idea of motion blur. Making this shot let me get a bit closer to understanding the most likely times to find the birds lifting off in the evening, and the best time to try to catch this with a bit of the last sunlight before sunset. I was also able to slightly better establish the shutter speed I would like to work with for this kind of image. The idea is to keep just barely enough shape in the birds that you can recognize what they are, but to allow the motion to blur things enough to eliminate the hyper-sharp realistic quality of the scene and to let the motion blur imply something about the actual flying motion of the birds.
