A Chukar Sentry Abandons Its Post

I’ve never been able to get a Chukar in flight or taking off, largely because they’re so hesitant to fly.  Even when they’re perched on an elevated rock they usually just hop to the ground when they’re ready to leave.  And when they do fly, typical of most upland game birds, they fly very fast, low to the ground and away from you which makes for an almost impossible target. But I got one yesterday morning, taking off.    1/5000, f/5.6, ISO 500, 100-400 @260mm, natural light This bird was acting as a sentry (also called a sentinel) for a small group of other Chukars nearby.  It’s observation perch of choice was a sign post that was high enough that it had to actually fly when it decided to leave.  I was too close to this bird for my 500mm lens so I quickly grabbed my 100-400 zoom lens and when it looked like it might be thinking of taking off I zoomed back far enough to give the Chukar enough room to fly into. I had plenty of light for a shutter speed fast enough to freeze the wings of even this buzz-saw flier (those relatively short wings on such a chunky bird really have to churn to get it airborne) and was lucky enough to catch the wings in a position I like.  A more appealing perch would have been nice but I’m pleased with the way most everything else turned out.

The Challenges of Photographing Birds in Flight in Low Light

Photographing birds in flight in relatively low light (dusk, dawn, cloudy conditions etc) isn’t easy.  In addition to the expected challenge of locking focus onto a fast and often erratically moving target, in low light you have the problem of getting enough shutter speed to get a moving subject sharp.   A potential solution to the problem is “opening up” – increasing the size of the aperture, which is the same as reducing the f-number – say as in changing your setting from f/7.1 to f/5.6.   This lets more light into the camera in the same amount of time, allowing for an increase in shutter speed to freeze the motion of the bird.  Opening up however has another effect – reducing depth of field, so less of your subject is likely to be tack sharp.  Another potential solution is to increase ISO.  Increasing ISO in digital cameras has the effect of seeming to increase the sensitivity of the camera’s sensor to light so that faster shutter speeds can be used but the downside to increasing ISO is that it can increase digital noise in the image. Sometimes in bird photography fantastic opportunities with birds in flight present themselves in less than ideal light.  Your best chance at an acceptable image under those conditions is to understand the interplay between your camera settings – how changing aperture affects shutter speed and depth of field and how changing ISO affects shutter speed and the production of digital noise.      Male Northern Harrier, 1/1250 @ f/11, ISO 800 It’s not often I get a…
