Vibrant, boisterous, and constantly in motion picking insects from any potential alcove formed by branches and flowering trees, warblers are the harbingers of spring ushering warmer weather with their arrival in early May. As winter finally melts away and the rain storms of April begin to bring the Northern Hemisphere back to life with budding flowers, trees and insects these little birds enter the final phase of their journey with their arrival to the shores of the great lakes. With well over 50 different species that migrate from South and Central America up to the breeding grounds across North America these small birds, no larger than 27 grams (or 1 ounce for my American brethren) add an irreplaceable and unmistakable pop to spring time. Just think of it, it took us a millennia to discover science and break free of gravity and travel the world, these little birds have been flying thousands of miles on a yearly basis for millions of years. Even though many species are in decline driven by habitat loss both in their wintering grounds (please buy rain-forest or shade grown coffee) as well as in their breeding territories, year after year these birds struggle their way up the coasts of North America and find their way up to the Arctic and Boreal forest to breed.
For many birders these species represent the ultimate challenge, even more so for a photographer. They are quick, often are found in dense vegetation where they search for their preferred meal resulting in an extremely challenging shot. For a wildlife photographer, a clean shot with a pleasant pose and background is nearly impossible, particularly when combined with poor lighting conditions in dense foliage that occurs in any time other than early spring. This is what makes the springtime so special from a photography perspective. To get one of those shots requires a unique combination of luck, perseverance and understanding bird behaviour. Often times the shots I get of these birds is of their underbelly as they continue to bounce in the tree canopy oblivious to my presence on the ground. Their song taunting us photographers, as if they understand that they are the jewel in a bird photographers eye, and one that will not be given up easily, not without a significant exertion of effort. It is for these birds in particular that the requirements for a large telephoto lens along with an excellent auto focus system become absolutely necessary. They single handily drive the cost of photography equipment, and are responsible for creating the wildlife photographer "look" - hat, dull to camouflage clothing with a massive piece of glass on a camera body walking around local parks or hotspots.
The best conditions for shooting these birds are either in the early morning / late evening with the weakest sun, or in overcast conditions. A cloudy sky often encourages their prey to stay close to the ground, and with little wind it means that these birds can be tracked and photographed at or near eye level - the prize position of a warbler. Overcast conditions also prevent harsh over blown highlights, and although may push a camera's ISO level upwards, means that the entire image presents a soft display. This offers a true representation of the warbler particularly when in a forest setting where wayward branches beginning to burst with flowers cast unwanted shadows on the subject and exacerbate the highlight / shadow divide on the subject. My best warbler shots are either in the shade of a tree, or taken on an overcast day, most often shot between 1/250 and 1/500 per second capturing a bird perched for a moment's rest. You can imagine then that with such fast paced and fidgety birds that the keeper rate is a disappointment. In fact in no other place other than warbler photography that the phrase "pixels are free" applies so well. Burst mode is a necessity, with 7-10 FPS preferred along with in-body stabilization firmly set to the on position. On a good day I will shoot nearly 1,000 shots, which results in 5 - 10 "keepers" where the bird is razor sharp, with a good composition requiring minimum edits (stray branch removal) and a pleasing pose. Yes, branch removal is a fairly frequent requirement with these birds. It is rare to find one in the open, and frankly as I treat my photography as a combination of art and natural scene I am not opposed to some basic to mid level editing. Although I will never add anything to an image, I will often add basic edits (sharpening, contrast, clarity) and take a stray branch out. But even all the equipment and editing in the world will not help if one does not research where and when these birds travel, and how they behave in the wild.
eBird is probably one of the most useful tools in a bird photographer's arsenal. Also submitting your observations supports citizen science projects as well. In breeding season habitat research is crucial, during the abundance of spring migration it allows a photographer or birder to be a little more "lazy" essentially visiting key hotspots will often result in a variety of species to grace the front of a lens or a pair of binoculars. Even so understanding their movements, how they’re behavour shifts in response to rain, wind, sun, bugs, different species of trees, etc. allows one to help predict their location and then their direction of travel. Often times these birds go where the bugs are. Which means water, and trees that offer ample insect habitat where they climb and eat birds. Finally there is also the topic of getting the birds attention. I have used recorded calls and phishing to see if I can get a bird out of it 's habitat. However, particularly when migrating I find that such actions result in the bird changing their behaviour from feeding to actively engaging in calling in the high canopy in search of mates or the aggressor or disturber so I tend to avoid such behaviour. In breeding situations if the nest has been established this may mean the bird leaves it's nest abandoned as it searches for the would be competitor. All in all I discourage this behaviour, and find that most of my best shots have come while observing natural behaviour. staying perfectly still and quiet as these birds continue to feast on their prey along the branches, while occasionally dueling each other. This way I become a part of the environment, and have had a few occasions where these birds have nearly landed on me or my gear!
But most important of all the biggest prerequisite to getting bird shots, is to get outside and into the natural environment. I find the biggest benefit of my photos isn't the shot I captured on my camera, but the feeling I get after spending a few hours in a natural environment. It builds a stronger appreciation for the world that we live in, and allows me to witness the miracle of biodiversity in all of it's glory often times only a few steps away from my home along a trail. This combined with the rush of getting that shot, makes warbler photography the ultimate, and most worthwhile challenge.
