Below is an example of a plan. It could apply to any species that is skittish and effective for just about any situation where mobile cover gives the advantage. Years of observing the Belted Kingfisher gave me a solid understanding of their behavior/habits which is always at the top of my list for gaining an edge and getting better shots.
In Pursuit of the Belted Kingfisher
For years I tried the chase technique with these birds and failed at every pursuit. Even trying drive up shots in my truck left me driving away grumbling. So it was time for a plan.
First I had to do some scouting and locate perches that were frequented by the birds. Then decide the best set up spot with the best light and cleanest backgrounds.
Next I needed to go under cover. I picked up a section of camo fabric from Bass Pro Shop for $25(4.5 ft. x 11 ft.). I like the dangling leaf cut out style because it provides peak holes and ventilation when it's warm. I'm only 5 ft. 10" tall so if you're less vertically challenged you may want to look for a longer section of fabric.
I drape the fabric at the half way mark of the length across the lens/camera/tripod. Then I use a mini bungee(multi pack-WalMart) to wrap the just behind the lens hood and hook underneath. Next take 3 spring clips and close up the front seam(below lens front). Now you simply climb in the back open seam and you're ready to go. I arrive before sunrise and assemble this by my truck, then carry the whole rig to my set up spot to allow me to quickly get out of sight.
It's a good idea to get into and out of the blind when there are no birds around to avoid the association of humans to the funny looking bush with the large glass eye. When arriving this doesn't always work out, there are times when the bird is already there and will fly off. I quickly get under the camo and many times the bird will return a short while later. This is a sign that the bird is very fond of this area for feeding. Returning with my blind in place shows the bird is willing to tolerate an intruder to make use of the perches that are proven for feeding.
Once in position, there's most often a lot of waiting time which I spend metering periodically, doing test exposures and of course listening for that familiar incoming chatter. Once a bird arrives there's an overwhelming instinct to swing the lens over and start shooting. But it's important to remember that you're disguised, not invisible, and these feisty birds are every bit as smart as they are skittish. When they arrive they always take long looks at me, so I wait and stay still. When the bird becomes less concerned about me it will either begin looking for fish below or start preening and that's when I VERY slowly pan over, pause to see the bird's reaction and take a shot as a test of the birds tolerance. If you are concentrating on only one perch when the bird arrives then there's no need to swing the lens around and of course that's a plus. It's more likely that the bird will have a few landing perches near its fishing perches and from my experience there's no telling which one will be favored each day.
As I mentioned when it's time to leave try to wait for the birds to leave first if possible. I've waited almost an hour in the past while a KF perched nearby on an obstructed perch. The more you visit a site and shoot, the less alarmed the bird will be when it spots the blind. It'll still be wary but less likely to do a fly-by-and "see ya" and actually land. Like always it's a good idea to have a spare battery and all needed items pocketed so you don't have to leave the blind and return. And don't forget to pack plenty of patience, it does require a good quantity. Don't be discouraged if you don't have success the first time out or even off and on for no apparent reason. Some days they show and some days they don't, but when they do it's a blast. Good luck everyone and I hope this helps in some way.
