Bird-Filled Dusk Sky, Central Valley

February 20, 2012 G Dan Mitchell 2 Comments

The edge of a huge flock of geese fills the dusk sky above seasonal winter ponds in California’s Central Valley.

I continue to learn the cycles of the migratory winter birds over the Central Valley of California. Early in February I twice visited a wildlife refuge in the area roughly between Merced and Los Banos in the evening. On the first visit, we arrived to find white flocks of Ross’s geese settled into ponds and hour or two before sunset. As the day came to an end the geese started to lift off and fly away in groups and by sunset there were almost non of these birds left at “our pond.” I began to think that the show was over for the night, and I switched from photographs centered on wildlife to working with the trees and ponds and fields as landscape instead. Then, well along into the dusk hour, we heard a sound to the south that signaled the presence of a large number of migratory birds, and a moment later rank after rank of them appeared and crossed above our position on their way to settle in nearby.

Less than a week later I was back in the same area. Again, we arrived to find the Ross’s geese settled in on a pond, though this time there were far more of them and they were closer to our position. Again, during the hour before sunset they began to lift off and fly away. And again, there was a quiet point right around sunset when it seemed that the migratory birds had all left and only a few smaller birds remained. But this time we had our eyes on the sky, and before long we spotted a small, moving cloud far to the west against the shadow of the coast range mountains, and we recognized it as a “flock” of birds. Soon we realized this was not just another small flock – it was a veritable cloud of birds that grew in size as it approached, became louder, and then quickly filled the sky above us with the sound and sight of thousands of wheeling birds.

The photograph shows just the far edge of this “cloud,” as the rest of the birds had just passed across our position and were mostly behind and to either side. Because I had a long zoom lens on the camera, I was just able to move toward its widest setting and quickly compose a photograph that included a bit of the pond, some trees and the far hills, and enough of the flock to suggest its size.

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 Taking Flight, Sunset

February 10, 2012 G Dan Mitchell 3 Comments

A large flock of Ross’s geese takes flight in sunset light, Merced National Wildlife Refuge, California.

Every time I go back to this location, it seems to just get better. On this early February evening I had quickly driven over the hill from the San Francisco Bay Area – well, OK, it is a two-hour drive – in time to arrive shortly before sunset and join a group of friends who had come down from the Mariposa, California area to photograph the same subject. I drove out around the “auto tour” route to a spot where I had shot just a week ago, near a viewing platform. Just past this point, there were thousands and thousands of (mostly, I presume) Ross’ geese filling a large pond right next to the gravel road. I set up and gradually, bit by slow bit, moved myself closer to the pond, working carefully to avoid spooking the birds. Eventually I got into position perhaps 20 feet from the pond.

Initially I photographed the birds that were settled in on the pond. As we did this, more birds flew overhead, and some joined this gigantic flock. But the light still wasn’t quite great. As actual sunset approached, the geese began to lift off in large groups. It seemed like there would be some momentary electricity in the air – perhaps I was just sensing a change in their calls – and suddenly a few hundred would simultaneously take off in a large group. I knew I wanted to try to get some photographs of these groups, and I also figured that ideally I would like a bit of cross-light from the very low and warm-colored sun and, if I could manage to pull it off, I would want to get some sort of landscape-ish background of trees and ponds and the distant hills in the golden evening light. I made several attempts before I captured this moment during which the group had just risen enough to mostly clear the trees across the pond.
