The Warbler Project


Introduction

Somewhere in the summer of 2002 I lost interest in photographing birds. After a spring project shooting red winged blackbirds, I shifted my attention to other subjects - deeper into macros and close-ups, and with some initial forays into landscapes.

Ironically, questing after dragonflies lead me to wonderful birding locations, and I found several areas that were thick with warblers, song sparrows, orioles, and other wonderful birds. They were good company, and most seemed to be gone before summer had even started. The yellow warblers in particular were intriguing, and so I made a mental note to come back and try to capture the images of these delightful little birds when they returned the next summer.

This spring found me continuing on with last year's wildflower project and it wasn't until late May that I finally got to the warbler fields. As with last year, the scrubby brushy wastes were full of yellow warblers, and their lilting call - Sweet sweet sweet I'm so sweet - filled the whole field. Along with the warblers, the songs of orioles, song sparrows, and gold finches also filled the air. Robins, cat birds, cuckoos, egrets, Canada Geese, and sandhill cranes also frequent the area.

And so, in the last week of May, I set off with Fudd-like determination, to photograph the yellow warblers.

 

Week One: Blind Leading The Blind

I have a pretty decent birding rig, but certainly not the best. I use a 400mm f2.8 EDIF lens, usually with a 1.4x, 1.7x, or 2x teleconverter. The teleconverters are 'matched' to the lens, and the optical performance is excellent.

As fine as this system is, it is not on par with the latest and greatest birding rigs. The ball head that I use works well, but is not as quick or as stable as the gimble heads. I'm also using a manual focus lens with no VS, IR, or USM. While the 1.7x converter adds some limited AF ability, the best I can do is watch my P's 'n' Q's when focusing and trying to hold things still for a sharp image!

In addition, my film based cameras do not provide a focal length multiplier like many digital SLR's. So while my 400mm is, well, a 400mm lens, someone with a digital SLR might find that same lens delivering the magnification of a 600mm.

 

The long and the short of it - I need to get closer to these little birds than someone with more advanced gear. In fact, I need to get within about 15 feet of these little birds to get a frame filling shot - and if they are more than 20 feet off, forget it.

The solution seemed obvious - I'd use a blind. Hidden away behind camo mesh fabric, getting close would be no problem. All I had to do was pick the right spot, set up the blind, and wait.

I surveyed the scrubby waste areas that housed the warblers, and quickly identified several nesting sites. In the tradition of old-time bird photographers, I decided to set up a blind near some of these sites. So after my surveying trip, I swung by Gander Mountain and picked up some camo material, and devised a makeshift blind. The next morning, I headed out to the spot I had picked, set up, and waited for the birds...

I quickly learned some interesting things.

First off, I understood why it is called a "blind". Namely - you cannot see a damn thing when you are sitting in one. Oh, you can see outside the opening that the lens points out of, but unless you create other openings (and somewhat compromise the whole idea of being hidden) you can't see to the left or right. And even if you could see there, you really can't move the camera and tripod around to get at the stuff you see.

Secondly, sitting in a blind is pretty boring. That thought came to be about 10 seconds after I first sat down in it, and stayed with me for the duration of my experiment. The other denizens of the field knew that the blind was out of place, so they took off. After all, they have hundreds of acres to roam in and plenty of backdoors to their nesting sites.

So, after a couple of tries with the blind, I gave up on that approach, and sat down to come up with something new.

Weeks Two And Three: Science to the Rescue

Yogi Berra once said "If you don't think too good, it's best not to think too much." Sound advice. But now I had a problem on my hands, and no recourse but to fire up the gray matter and think this thing through...

First stop - Donald Stokes Guide To Bird Behavior. So - just what were my little warbler friends doing with their lives?

It was an interesting read, and with each paragraph the bells kept going off in my head. Yellow Warblers set up small territories around their nest sites. The females tend the nests, the males forage for food and defend the perimeter of the territory from other males.

The solution seemed obvious. I knew where a lot of warbler nests were, and I had seen the males on singing perches defending their territories. Since testosterone pumped males will invariably engage in high risk behavior, I decided to setup up the border areas between the nesting pairs' territories. There I could get shots of the males singing to mark their territories, and maybe even get close to some males engaging in territorial skirmishes.

This plan worked exactly as intended. The males often seemed oblivious to me, they engaged in combat right before my nose, and sang their hearts out in trees right next to where I stood. I really managed to get close to the birds - two combating males actually tussled right in front of my nose (and behind my camera!)

Over the course of the second and third weeks of shooting I tried to refine and improve upon this strategy. I identified more nests, determined the prime singing posts used by the males, and found the areas where multiple territories overlapped. I saw lots of interesting things - particularly in the tussles and fights between males - but had no good opportunities for photographs. While I got close, I only got close to moving birds.  I'd love to get a shot of two or three males sparring in midair - but that is all but impossible.

It was a good plan, but not for photographing the birds. In those border areas the males were either 30 to 50 feet up the trees, singing their songs, or vigorously going at it with each other. At this point I had put in 7 or 8 days of shooting, and was thinking about giving up on this project.

A New Perspective

When all else fails, do an internet search. So I sat down with Google.com, entered "photographing warblers" and started to look through the results. That's when I stumbled into Arthur Morris's article on photographing warblers. I had read Morris's Birds as Art, an excellent guide to the art and science of photographing birds, and so I was interested in seeing what he had to say about photographing warblers.

What he said, among other things, was that photographing these little birds took a lot of time and patience. After reading his article I realized that, at best, I was just getting started.  I was far from the point where I should be throwing in the towel. So I set out with renewed determination.

Week 4: Wandering Around

And so I started out afresh, and marked my new determination with a colossal blunder and a bit of serendipity.

A nice start - but the ISO 400 print film really hurt this photo!

Early in week four, I headed out on a gloomy morning that promised thunderstorms later in the day. Given the poor light, I decided not to waste a roll of expensive Provia 400F, and instead loaded my camera with Superia 400 print film and headed out to some promising areas.

Once again, the pickings were slim. But as I staked out key inter-territorial areas, I heard a rumble of thunder, and a handful of raindrops spat down out of the sky. I shouldered my camera, and started back towards the car.

The rain did not start up for a while, and as I headed back I encountered some of the best opportunities I had run into so far. I even managed to get off a few decent shots - though the ISO 400 print film assured that they would be doomed to failure.

For my next visit, I set the camera and lens on the tripod, left the legs extended, and just started wandering around the neighborhood.

The results were worth it. While wandering about I encountered many interesting warbler scenes, but also some interesting scenes with song sparrows, cat birds, and orchard orioles. And by the end of week four, I had finally gotten a decent shot of a female yellow warbler.

Week 5: Observer and Observed

Thoughts wander when you spend a few hours standing in a field. In my case, I found myself thinking of the birds and the perils they endure, the loss of their environment, St. Francis, and ultimately a little scrap of quantum theory.

That little scrap of quantum theory states that by merely observing a situation, the situation is altered. It's pretty heady stuff and frankly, beyond my understanding, but it occurred to me as I looked around the fields I had been visiting these last few weeks.

During the course of my visits it was clear that the birds and the other creatures of the field were watching me as intently as I was watching them. As I visited some of the same areas over and over, the birds became more and more accustomed to me. The fifth week was the most intensive in terms of visits - I returned to the field four times. By the end of the week the birds in some small areas had come to accept me, and not only ignored me, but would come closer and seemed more relaxed. I took several photographs, though the harsh sunlight lead to mixed results.

This was also the week that the warblers started to leave, and I began to see empty nests in the scrubby bushes. By late July, they will all be gone, heading back to South America.

.Week 6: Closer Yet

A week passed before I could get back to the field again. A brief heat wave had just broken, and I hiked into the field under light overcast skies. A coyote stepped out of the brush and totted along the path several feet ahead of me, only to meld back into the woods after a short distance.

I returned to the spot were I had been photographing a male warbler in the preceding week. To my delight he  appeared within a few minutes. He was more relaxed than ever before, and allowed me to get several shots over the period of a few hours. I finally packed it up as the sky darkened and rain started falling. 

On the way home I saw a small yellow spot on the highway pavement - a yellow warbler, killed by a passing car. A poignant reminder of the many perils this little birds face as they make their way through the world.

 

Week 7: The Confident Parents

A week went by, and now it's July. I got back out to the warbler field on July third.  Although the birds are common throughout the park, the area where I spent most of my time is adjacent to two small lakes - Whitford lake and Jackson Hole.  There is a small dirt parking lot with boat launches, one on each side, granting access to the two lakes.  On one side is the scrubby area where I photograph, second growth forest is on the other.

As I pulled up I saw a pair of Warblers in the dogbane bushes next to the parking lot.  The bushes - which are been in their final stages of flower when this project began - were now festooned with bright red berries.  A pair of yellow warblers were gathering food in the area, keeping each other apprised of their whereabouts with a constant call of  "chip chip chip."  As I set up my gear I hear a third voice in the chorus of "chip chip chip" - this one softer than they others. 

After watching the birds for a while I realized that one or more of their fledglings were ensconced deep inside of a thick dogbane bush.  The parents were gathering up food - caterpillars, mayflies, at least one cabbage white - and bringing it to their young.  The two adult birds seemed to be completely unconcerned about my presence, and often would gather food in the bushes right next to where I was standing, just a few feet away.

The bright light of a high overcast day made this a good day for photographing, and after spending some time with this very cooperative pair, I headed down into the areas where I had been shooting in past weeks.  The numbers of warblers were definitely thinning, and though there were still several males out singing, there were certainly fewer birds than before.

Week 8: Going... Going...

After a long weekend with hot temperatures punctuated by violent thunderstorms, I returned early Monday morning to check on the birds.  My wife and I had walked through a few days before, just out hiking, and it seemed then that there were significantly fewer birds - but it was mid afternoon and I figured this was probably more due to the time of day than anything else.

On Monday morning, it was clear that the critical mass had shifted.  I ran into a pair of birds and a fledgling in the same spot I had encountered then during the previous visit.  But on this day, under the overcast sky and in the brush still dripping with the previous night's rainfall, the two adults seemed more wary and anxious. I took a few shots, and headed back into the fields.

Some of the yellow warblers were present, but in greatly reduced numbers.  Their songs still rang out through their fields, but as I listened there seemed to be a lonely quality to their notes.  After a while I realized that there was a very real change in the pattern of song.  A few weeks earlier each song would be answered with another song, and a cascade of songs would flow out from all directions as bird answered bird answered bird.  But this morning that pattern was largely gone - I'd hear one bird sing, it would repeat the song after a short while, but there were seldom answering calls. 

I saw few subjects during this visit, and after a few hours headed in.

The next few weeks saw a sharp decline in the numbers of yellow warblers - but they have not all moved on.  As recently as July 25th I still ran into pairs of these yellow birds.  Although I have now switched from shooting birds to pursuing butterflies, dragonflies, and the occasional landscape shot, I still enjoy spotting a warbler now and again.  And someday soon when I look up and see then no more, I'll look forward to next summer and their return from South America.

On Equipment

As mentioned, bird photography is very equipment intensive. This is quite possibly one of the biggest pitfalls that faces bird photographers. Problems are often looked at from a gear based orientation. One often winds up asking what gear is needed to solve the problem while paying less attention to understanding the birds or devising ways to get closer.

 

In terms of my gear: I use a Pentax Pz-1p camera, A* 400 f2.8 lens, 1.7x AF adapter, and AF500ftz flash. In a few cases, I used the TC-2x L teleconverter instead of the 1.7x AF adapter.

The lens and 1.7x AF adapter combination is he equivalent of a 680mm f4.5 lens. The AF adapter is a somewhat unusual piece of equipment. It basically is a 1.7x teleconverter, but it hooks up to the camera's AF system which moves around the optics within the adapter. The result is that, when used on a manual focus lens, the adapter offers some auto focus capability. While it actually works pretty well with fast 50mm lenses, the AF ability with the 400mm f2.8 is very limited. With close subjects, the effective autofocus range offered by the adapter is a few inches. However, it does allow the AF to snap the shot into crisp focus once it is more or less in focus manually.

The camera is left in manual mode. I would generally shoot at an effective f6.7 (f 4 on the lens when using the 1.7x adapter.) The flash was mounted on a flip bracket above the body. Flash was in TTL mode, with flash exposure compensation usually set to -1.3 stops. I did not use a flash extender - since I was hoping to get within 15 to 20 feet of the bird, the flash itself was certainly powerful enough.

This rig was mounted on a Bogen 3036 tripod with 3048 heavy duty ball head. Total weight of the setup is about 30 pounds - heavy enough to notice but not overwhelming, even when carrying it around for a whole day.

When hiking longer distances or straight through, without stopping to shoot, I'd drop the camera and lens into a Domke long lens back and toss that, flashes, batteries, etc into an old army surplus backpack. With the tripod slung over my shoulder and next to the backpack, walking even several miles, even through brushy areas, is not a problem.

Usually, though, I'd mount the lens and camera onto the tripod and carry the whole rig, typically with the legs extended. That made it easy to just plop the rig down and start shooting almost immediately. The only daunting part about carrying the whole rig around was getting through scrub and brush. Often I'd have to hold the rig over my head as I wandered through waste or chest high patches of brush.  

I terms of film, I generally used Kodak E100S, my mainstay for slide film. On a few overcast days I used E100VS. I also shot a bit of Provia 100F and some Provia 400F.

Ultimately, though, I'm not sure that equipment is really all that central to successful bird photography.  Cultivating a relationship and understanding with the birds seems to be more central - and you can't buy that in any camera store.

Final Thoughts

Birds are good company, and hanging out with them and even - perhaps - getting to know one or two on an individual basis is a good thing.  But bird photography leaves me feeling unsatisfied.

The problem, in my mind, is that bird photography is largely a prescriptive venture.  The ideal bird shot has been defined: a crisp clean image of the bird against a blurred and uncluttered background.  Bird photography is largely an exercise in conforming to this preconception. The extent to which you can duplicate shots already taken, or improve upon their technical merits, is the measure of success or failure.

Arg... If the birds were not such great company, I don't think I'd bother.  And while I am sometimes successful in conforming to the preconceptions, I am still thirsty.  There must be more, there is more.  And I guess that will be the next project.  It will probably take more than 6 weeks though....
