Ross’s Geese Take Flight, Dusk

March 3, 2012 G Dan Mitchell Leave a comment

A flock of Ross’s geese take flight at dusk above a Central Valley pond, California.

Yes, another photograph of geese taking flight above a California Central Valley pond. I can’t help myself! :-) After photographing the dwindling flock, as they left in large groups during the hour before sunset, at the point of most beautiful light there were only a few left. This group was among the very last to depart from this pond, and at this point it was dusk and the colors had gone from the crisp blues of an hour earlier to warm pinks and reds and purples. We were lucky enough to be very close to this large flock for at least an hour.

I’ll use this photograph to make another technical observation. I made what might seem like an odd choice regarding exposure for this shot. Here I wanted to try to stop the motion of the birds as they lifted off. (In other photographs of this subject I intentionally allow the motion to blur.) This meant that I needed a relatively short shutter speed. Even after raising the ISO to 400 and opening up the largest aperture on this long lens, the result was still going to be underexposure. for what I had in mind for this sequence of shots, I wanted to avoid using an ultra-high ISO with the attendant increase in noise. So I chose to deliberately underexpose these shots by perhaps a couple of stops, trusting that I’d be able to compensate for this in post since I shoot in raw mode. In other words, if you are the sort who scans EXIF data for exposure information and then tries to make sense out of it or even use it yourself… you have been warned! :-)

Tundra Swans, Dawn

February 21, 2012 G Dan Mitchell 1 Comment

Tundra swans in dawn light above the Central Valley of California.

This is the second photograph of this particular group of tundra swans that flew low over our position near the end of Woodbridge Road in the California Central Valley near the end of January. With all the challenges of photographing flying birds in limited light and with long lenses, it is no wonder that one gets a less than 100% success rate with these photographs. But every so often all the pieces fall into place and you end up with something that is not another slightly out-of-focus, slightly mis-aimed, over- or under-exposed photograph of the silhouettes of bird undersides. Seriously. ;-)

This group came over at a relatively low level, though not so low than individual birds would fill the viewfinder. By default, I usually begin with the camera in “landscape” (horizontal) mode for this sort of subject, but because these birds were almost directly overhead and lined up “vertically” rather than strung out in a line, I decided to quickly shift the camera to “portrait” (vertical) orientation after one initial exposure as they approached. Now the trick was to try to keep my eye on one bird that needed to be under the AF point, while simultaneously remaining aware of the entire flock so that I could keep them within the boundary of the frame and try to catch them at a point when they were not blocking one another. The fact that I got the beautiful morning light coming from below was partially due to being there good and early, and possibly due to the birds thoughtfully positioning themselves to allow this. Thank you, tundra swans!

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.

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.
