Photographing A Blue Gray Gnatcatcher and Choosing Between Shooting Modes

Photographing A Blue Gray Gnatcatcher

When I first saw this tiny songbird through the lens, he was looking back at me with an inquisitive look on his face. (Birds usually take flight at the sight of the camera, especially when it’s so close.)  I kept my wits, aimed the camera and set off a burst of continuous shots. Seconds later he lost interest in me and hopped to a different branch. Initially, I confused this diminutive wonder for a warbler because of his thin straight bill and flitting behavior while foraging for food. But once I was able to see a profile of his body, especially those swishing long tail feathers, I knew he was a gnatcatcher.

My camera was set to continuous shooting drive mode paired with Al Servo focusing. Without that pairing, I simply would not have been able to capture multiple shots in sharp focus of this fast moving little bird.

Don’t Confuse Shooting Mode with Focus Mode

Lots of photographers confuse shooting modes with focusing modes. They are very separate functions, even though they work hand-in-hand.

Shooting Modes simply control how the shutter release operates- including self timers. There are seven shooting modes available on modern Canon DSLR cameras:

  1. Single shooting mode
  2. High Speed Continuous shooting mode
  3. Low Speed Continuous shooting mode
  4. Silent Single shooting mode
  5. Silent Continuous shooting mode
  6. Self Timer 10 sec remote
  7. Self Timer 2 sec remote

Focus Modes kick in immediately after the shutter is depressed (autofocus only) and determine how the camera will achieve focus. Modern DSLR Canon cameras have 4 focusing modes:

  1. Manual Focus (no autofocus)
  2. One Shot Autofocus (will initiate focus once)
  3. Al Servo Priority Autofocus (continually tracks and updates focus)
  4. AI Focus (automatically alternates between One Shot and Al Servo modes, depending on the situation)

Shooting Mode Paired with Focusing Mode

Once you choose a shooting mode, it’s critical to understand and decide how the camera will focus in this shooting mode.

  • If Single Shot Shooting (1 or 4 above) mode is paired with One Shot Focusing mode, the camera will lock down focus once (and ding if it is set to ding) every time you press the shutter. (NOTE: If the camera can not lock down focus, the shutter will not fire, no matter how much you push it.)
  • If Single Shot Shooting (1 or 4 above) mode is paired with Al Servo Continuous Focusing mode, the shutter will burst in quick succession (cache and memory card size allowing) as long as you hold down the shutter button, but auto focus will not continually adjust focus after that first shot. All shots taken after the first shot will be based on how the camera focused the first shot. (No good in fast moving and chaotic bird photography.)
  • If Continuous Shooting (2, 3, or 5 above) mode is paired with Manual Autofocus mode, you can burst away all you want, but the lens will not focus unless you do it manually. (Read more about Manual focus here.)
  • If Continuous Shooting (2,3, or 5 above) mode is paired with Al Servo Continuous Focusing mode, the camera will initiate and manage focusing operations after that first shot, as long as you continually hold down the shutter. (The photographer must accurately track the subject for this pairing to be worthwhile.)  

Al Servo Paired with Continuous Shooting

I almost always pair a continuous shooting drive mode with Al Servo Priority Autofocus mode for bird photography. With this pairing, Al Servo Autofocus can “predict” and keep focusing the lens during the continuous shooting burst —as long as I make sure that the focus points (whether all of them or just one) can find the target.

How Fast is Al Servo Paired with Continuous Shooting?

When you pair a continuous shooting drive mode with Al Servo Priority Autofocus mode, how fast your camera is able to “burst” during continuous shooting depends on the following:

  • The size of your camera’s buffer (especially if you are shooting RAW)
  • Inherent limitations of the camera and lens
  • The size and speed of memory card
  • The Al Servo priority autofocus settings.   (Huh?)

More Settings for Al Servo Priority

NOTE: This is an example of when menu complexity in a DSLR camera can be daunting. It’s no wonder that a lot of photographers prefer to use their camera’s default settings; or perhaps just fiddle with one or two plain vanilla automatic functions and use those forever, no matter the shooting environment.

One more thing must be customized in the menu after you have paired Continuous Shooting Drive Mode with Al Servo Priority focusing mode. You must also choose how you want the camera to prioritize focusing. 

The following settings are available:

  • Prioritize burst speed,
  • Prioritize focus accuracy; or
  • Prioritize a balance between the two.

My Choice: Maximize Sharp Focus

Prioritize focus accuracy is an easy choice for me. In bird photography, I always, always want tack sharp photos, so I am willing to sacrifice frame-per-second (FPS) burst rate speed. When I choose focus accuracy over burst speed, my keeper rate is higher. The continuous burst may be slower, more interrupted -especially in low light-causing me to miss some of the action. That’s OK with me.

I will do whatever it takes not to compromise sharpness.

Photographing the Blue Gray Gnatcatcher and Thoughts About Taking a Grand Birding Adventure

Photographing the Blue Gray Gnatcatcher

The Blue Gray Gnatcatcher is a very good find for me. This tiny little songbird was hiding in the low branches of a densely wooded patch in the Allegan State Game Area. I was sitting in my car, lens resting on the car door, when I first spotted him. I was able to follow his movements despite the dense foliage because he was flicking his tail feathers back and forth, uncovering insects and then chasing after them. He came out of the branch and leaf clutter for only a minute, but it was long enough for me to shoot two full body shots (500 mm w 2x extender). And then he was gone.

The Easy Road

I’m lucky to live near the Allegan State Game Area (Allegan County, Michigan) and the Kellogg Bird Sanctuary  (Augusta, Michigan) where there are plenty of birding adventures to be had.  In late summer, I often sit near my library window and hope that new warblers and vireos will take a break from their long migratory journeys and rest in my yard. (Amazingly, our yard has become somewhat of a hotspot this Fall. For more info about that, see this post.)  With these great resources nearby, I generally don’t have to travel more than 75 miles to photograph birds.

Traveling to Photograph Birds

Going on a long distance American birding expedition does appeal to me however. I read about the exhausting and exciting adventures of birders who travel far and wide with their cameras to find and photograph birds and I imagine myself on that sort of long journey. Traveling efficiently and effectively no doubt means that you have to leave behind your best long lenses, and maybe your best camera. There was a time I would have thought that intolerable, but since I’ve started photographing new migrating birds through my library window, I’ve come to accept the noisy, leaf cluttered photos in exchange for the close, eye level view and the thrill of watching and photographing new birds.

Dorian Anderson’s Journey

One birder’s long distance trek is particularly impressive. Dorian Anderson is spending a year traveling thousands of miles by bicycle in search of as many birds as possible and writing a blog about his adventures. He embarked on this journey in Massachusetts, and headed south to Florida and then west toward California. See this link for his timeline, trip strategy, and winding route. Dorian said that he misses his primo equipment (500mm/1.4x/1D) but he still manages to include quite a few fabulous photos in his daily blog.

Biking for Birds

Dorian is using this biking/birding adventure to raise funds for The Conservation Fund and the American Birding Association. At the time of this writing, he has seen more than 557 species and raised thousands of dollars for bird conservation causes.

I envy Dorian’s running bird list, and admire his resolve, strength and fortitude. I checked his list, but did not see a Blue Gray Gnatcatcher. Such tiny little birds to find. He did however list the following gnatcatchers:

450 – Black-tailed gnatcatcher
451 – Black-capped gnatcatcher
