Welcome to the ninth in a 12 part series about how to improve your nature photography.

Step #9 – Learn biology.

You want to be a better wildlife photographer?  Learn biology. This was the advice given to me when I first got into photography. At the time I had no idea I would go on to earn a doctorate in wildlife biology. Now, 19 years later, I realize learning biology is the best photographic advice I ever got.

Wouldn’t it be great if we knew what animals were going to do before they did it? It might surprise you to know that animals are predictable. They have specific needs and tend to respond to situations in predictable ways. By understanding their behavior, it becomes possible to not only predict the behavior, but to increase your chances of capturing it on film. Don’t believe me? Lets look at an example. Ever tried to capture an image of a bird taking off? It’s hard isn’t it? You sit there for hours, only to blink as the action starts. Next time, wait for the bird to defecate. Seriously. Taking off is difficult and birds do everything they can to lighten the load. Using this knowledge, it becomes much easier to get the shot.

At the same time, behaviors often occur but pass by unnoticed. Without understanding the context within which a behavior falls, we are unlikely to recognize it for what it is. Take elephants for example. Why are biologists so enthusiastic about elephants? Sure, they are charismatic, huge, and fun to watch, but so are countless other species. Elephants are what biologists call keystone species, meaning they have a more dramatic impact on their environment they one would expect based on their population numbers. In fact, after humans, elephants are probably the most destructive species on the planet.

You see, elephants tend to have a love-hate relationship with trees. They use trees for a variety of activities including food, moisture, scratching, and play. The problem is that elephants have a lot of weight to throw around and they have a habit of knocking trees over. Do this enough and the trees start to disappear. The result is a gradual shift from forests to grasslands. Obviously this has an impact on not only the trees, but also the animals that live in the affected forests and grasslands.

What does this have to do with photography?  By understanding the biological relationship between elephants and these different ecosystems, a new world of photographic opportunities opens up.  Suddenly, an elephant standing next to a broken tree trunk has new meaning as does the long-term implications of reduced elephant populations throughout much of Africa.

The following are a collection of images that were all created either to record a particular animal behavior or were made possible because of knowledge of specific behaviors.

Two male lions fighting over a female lion.

While male lions often form coalitions when taking over a pride, competition still exists.  Access to receptive females is the primary source of competition and watching the interaction between individuals can provide clues about conflict before it happens.

Male and female lions snarling after mating, Serengeti National Park, Tanzania.

When lions mate, copulation is brief and repeated frequently (over 100 times a day).  It also ends with a short fight as the female snarls and attacks the male if he doesn’t back off.  Knowing this pattern let me capture the male’s expression.

Male impala chasing young male away, Serengeti National Park, Tanzania.

Impala social structure is based around a single, alpha male controlling access to a harem (group of females).  For a two-month period, this male will spend all of his energy mating and chasing off rival males.

Fighting is dangerous.  A hurt animal is often a dead animal and even the winner of a fight risks injury.  As a result, many animals have developed highly ritualized contests that establish dominance without resulting in an all out fight.  For elephants, these contests take the form of pushing matches.  Two elephants come together, interlock trunks, and push.  While it is difficult to photograph real contests, it is a common sight to see young elephants practicing their pushing skills.

Creating an interesting picture of a wildebeest is hard.  My most successful attempts have all focused around the behavior of the alpha male to patrol his harem against intruding males.  This shot clearly shows the alpha male on the lookout for rivals.

Cats sleep almost 20 hours a day.  This makes it challenging to get a picture of them doing much of anything.  Capturing a cheetah in mid-yawn is cause for excitement, even if it signaled his plan to go right back to sleep.

This cheetah was photographed in the Serengeti during a recent African photo safari.  The image was captured using a Canon 1D mark 4, 500mm IS lens, at 200 ISO.  The image was shot from a vehicle and the camera and lens were supported using a beanbag.

I wanted to touch base with everyone and let you know that I haven’t forgotten about the blog.  The combination of high school class trips, end of the grade term, and visiting relatives, hasn’t given me much opportunity to get any blog posts up.  I expect for things to be back to normal next week.  In the meantime, I hope you enjoy the above image of two male hippos settling their differences.

The image was captured using a Canon 1D mark 2, 500mm IS lens, at 400 ISO.  The image was shot from a cliff overlooking the Mara River in the northern Serengeti, Tanzania.  There were almost a hundred hippos in the section of the river we were watching and I was constantly scanning the pods in an attempt to predict fights before they started.  By handholding the lens (a very heavy lens), I was able to react fast enough to capture the action before it ended (usually only a few seconds after it began).  Wildlife photography at its finest.

Previously, we discussed a typical lion hunt and how these large cats use ambush techniques and group hunting tactics to increase their chances of catching their prey.  Of course, lions are not the only large predator found on the savanna, nor are they the only group hunters.  Spotted hyaenas are regularly sighted in grasslands and have proven to be extremely efficient hunters despite the misconception that they are scavengers.  Unlike lions, hyaenas are dogs and have evolved a much different approach to hunting.

Spotted Hyaenas are pack hunters, but they do not ambush their prey.  Hunting mostly at night, hyaena are outstanding long distance runners.  The quick trot commonly seen in dogs is used to run prey to the point of exhaustion.  As night falls, a pack of hyaenas will spread out and openly approach a herd of antelope.  The antelope respond, moving in the opposite direction.  This process repeats over and over as the hyaenas evaluate their prey.  Over time, individual antelope begin to stand out.  The small, the old, and the injured all have a difficult time keeping up with the herd.  As the night progresses, the hyaenas target these weaker individuals and ignore the rest of the herd.  The hyaenas continue their advance, forcing the antelope to constantly be on the move.  As the hours pass by, the antelope, weak to begin with, can’t maintain the pace and falls to the ground.  It is at this point that the hyaenas move in for the kill.

Photographic Tips – Unlike the cats, hyaenas and other dogs tend to be involved in prolonged hunts which offer numerous photographic opportunities.  Finding a hyaena pack at sunset can provide the opportunity to watch them begin to work the herd.  Since most of the time is spent in a slow chase, panning and frozen motion shots can be an effective way to document the action.  It can also be effective to record images that include both hyaenas and their prey.  Telephoto lenses help to compress distances and will give the appearance that the predator and prey are closer together then they really are.  Unfortunately, the biggest challenge to photographing these nocturnal hunters is the absence of light.

The above image shows a spotted hyaena considering its chances of catching an alert Thomson’s gazelle.  The use of a telephoto lens helped to compress the distance, making the antelope appear to be much closer to the hyaena, thereby emphasizing the relationship.  The image was created using a Canon 1D mark 2, 500mm IS lens, at 200 ISO.  The image was shot from a vehicle and the lens was supported using a beanbag.

All animals need three things to survive: food, water, and shelter.  How they get these things can differ in dramatic ways.  Take lions for instance.  Not only are lions carnivores, but they are the top predators of the savanna.  In a face to face confrontation, few animals can hold their own, much less beat a lion.  Yet finding food is not easy for lions.  Lions have been around for a long time and most of the animals they prey upon have evolved methods of escape that stack the odds against the lion.  A single lion only succeeds in about 15% of its hunts while a pride is successful about 30% of the time.

So how exactly do lions increase their chances at a successful hunt?  Like most cats, lions are not good distance runners.  They can move quickly, they can not maintain the speed needed to outrace most of their prey.  As a result, lions have had to come up with something else.  Their solution is cooperative hunting, with the members of the pride working together to bring down prey.  In most instances, a hunt begins with 2-3 lions walking in the open towards a herd of zebra (or other prey).  In all likelihood, the zebra see them coming and respond in the obvious way.  They take off in the other direction.  Unfortunately, they are heading into a trap.

The lions in the open are decoys, moving forward with the sole purpose of generating a response.  The real threat are the lions hiding along the zebras’ escape route.  As zebras pass through this hidden gauntlet they run the risk of becoming dinner.  Once an animal is targeted, the entire pride helps to bring it down.  Cooperative hunting improves their success rate and lets the pride target larger prey then would normally be possible.

Photographic Tips – How do we use our knowledge of lion hunting to capture better images?  In this case, the lesson to remember is that you probably don’t see all of the lions.  During a hunt it is easy to focus on the decoys (that is their job after all), but that is rarely where the action happens.  Watch for the ambush and be ready to change your focus quickly as the action shifts.  Also, don’t waste too much time focussing on the males.  Females are the real hunters of the pride.

The lioness pictured above was photographed feeding on a dead wildebeest in Serengeti National Park during one of my African wildlife photo safaris.  Unfortunately, we didn’t see the hunt, only the aftermath.  The image was created using a Canon 1D mark 2, 500mm IS lens, at 200 ISO.  The lens was supported on a beanbag while shooting from a vehicle.

The spotted hyaena is one of the most misunderstood animals to be found in Africa.  Long believed to be a scavenger, the hyaena is a perfect example of how partial knowledge can misrepresent reality.  In this case, the image of hyaenas as scavengers came about through direct field observations.  On numerous occasions, scientists would go out into the field to find a pack of hyaenas waiting eagerly on the outskirts as a pride of lions fed at a kill.  As lions ate their fill, hyaenas would sneak in, grabbing small pieces before being chased back.  It wasn’t until the lions finished and abandoned the carcass that the hyaenas would began to feed in ernest.  These observations promoted the hyaena’s image as a lazy scavenger.

It wasn’t until night vision equipment became readily available to field researchers that the true story was revealed.  It turns out that hyaenas are highly efficient hunters.  In fact, they are far more successful then lions when it comes to hunting.  What scientists discovered is that the majority of lion kills they had been documenting were in fact hyaena kills.  During the night, packs of hyaenas would take down prey, only to have their kill stollen by lions.

In hindsight, lions seem to be the lazy ones.

This female spotted hyaena was photographed in Ngorongoro Crater, Tanzania during one of my African wildlife photo safaris.  The image was created using a Canon 1D mark 2, 500mm IS lens with a 1.4 teleconverter, at 400 ISO.  The camera and lens were supported on a beanbag while shooting from a vehicle.

Great white shark chewing on seal decoy, Cape Town, South Africa.

(click on the image to see larger version)

I walked out of the house this morning and got hit in the face with a blast of cold air.  Winter appears to have arrive din San Antonio.  The sudden chill brought back memories of my time in South Africa where the wind coming off the Atlantic goes right through a jacket and chills to the bone.  Over the years I have made three different trips to South Africa.  The first two trips were part of my graduate research and involved living on a fur seal colony in the middle of a diamond mine for two months at a time.  There is nothing quite like waking up in the morning to be greeted by 300,000 fur seals, none of which are happy to see you (fur seals were hunted in South Africa until 1990 and are still hunted in Namibia).  My third trip was to participate in The Wildlife Film Academy’s month long wildlife filmmaking course.

Cape Town is one of the best places to see Great White sharks and I wasn’t about to miss the opportunity to get in the water with one.  So, in January, 2000 I made my first attempt.  Unfortunately, no one told the sharks.  The result of five hours on the water was…….nothing.  Actually, that was not entirely true.  We did see a seagull, but no sharks.  In June, 2008 I made another attempt and this time I got lucky.  Within a half-hour of arriving on site, the sharks started to come in.

You might be curious about how the boats bring the sharks in.  Do they dangle tourists over the side and say, “come and get it!”  Fortunately, no.  Like other sharks, Great Whites have an amazing sense of smell but poor eyesight.  Chunks of smelly fish (called chum) are dropped into the water to get the shark’s attention.  Once the shark arrives, its attention is further held by a foam buoy cut into the shape of a seal.  Great Whites are seal hunters and frequently target their prey by silhouetting them against the surface.  The seal buoys act as decoys, keeping the sharks interested so that they stay around the boat.  Every now and then they even grab a buoy in their month and check it out.  My guess is that buoys get replaced frequently.

All of this added up to a great opportunity to see the sharks up close.  Not only from the surface, but also in the water.  Taking turns, divers spends time in the water watching the sharks swim past.  At one point, we had five different sharks swimming circles around the cage.  Great whites are large with the biggest females (females are larger then males) measure over 25 feet long!  The sharks around our boat “only” measured about 12 feet, but I am sure I still qualified as a possible snack.  More then their size, what amazed me was how well they blended in.  You would think a 12 foot long fish would be easy to spot.  Nope.  Over and over again, I was surprised as these massive predators appeared out of the gloom just a few feet away.  While they didn’t act aggressive, I was happy for the cage.

The ultimate irony is that I didn’t have the right equipment to photograph the sharks.  While I did have my camera, I don’t own an underwater housing system.  So, while my above water pictures of the sharks turned out well, my underwater shots were taken with a $10 disposable film camera.  At least the memories are in focus.

The image above shows a Great White Shark chewing on a seal buoy decoy.  I like how he is smiling for the camera.  The image was captured using a Canon 1D mark 2, 24-70mm lens, at 200 ISO.  The camera was handheld.

Two elephants play fighting, Serengeti National Park, Tanzania.

(click on the image to see larger version)

These two elephants can teach us a lot.  During a break in her midday meal, this adult female approached one of the young males and started a lighthearted pushing match.  While entertaining to watch and great to photograph, the purpose of this contest was serious.  At some point in the future, this young male will be on his own.  As he progresses through his teenage years his testosterone levels will increase to the point where he is a pain to have around (both figuratively and literally).  When that happens, the herd will kick him out.  From there, he will have to make his way in a dangerous world without the support of his family.  In addition to predators, he will have to deal with other male elephants.

Elephants are massive animals, with bull males weighing in at over 24,000 pounds.  With that much weight being thrown around, it is easy to imagine the damage that would result from a fight.  The problem is that such fights have a good chance of hurting both elephants, not just the looser.  With no vets in the bush, even a minor injury can become life threatening.  As a result, bull elephants have devised their own way of determining a winner without resorting to an all out battle.  Their solution: pushing matches.  When two elephants compete, they face each other head-to-head and interlock their tusks.  Once in position, the pushing begins.  Back and forth they go, each trying to gain leverage over the other.  In just a few short minutes it usually becomes clear who is stronger and likely to win if the fight turned serious.  This gives the looser the opportunity to depart gracefully and in full health while settling the dispute.

You might be wondering how this relates back to photography.  Never fear, it does.  Just as that adult female wrapped an important life lesson into a game, photographers need to remember to importance of being prepared.  Wildlife does not wait for you to get your camera ready.  Nor does it sit by as you try to figure out the best settings to use.  If you want the images, you have to put in the time and effort so that you will be ready when the opportunity occurs.  The technical side must be second nature, which means hours and hours of “play” (doesn’t that sound so much better then work?).

The image was captured in the Serengeti National Park, Tanzania during a wildlife photo safari.  The image was created using a Canon 1Ds mark 3, 500mm IS lens with 1.4 teleconverter, at 400 ISO.  The image was taken from a vehicle and the lens was supported using a beanbag.

Brown bear standing in the water looking for salmon, Katmai National Park, Alaska.

Bears are fun to photograph.  Seeing bears in the wild is an amazing experience, and trying to capture their strength and power is a constant challenge.  These enormous creatures spend hours running through deep water chasing salmon without any signs of tiring.  It is an fantastic spectacle to watch, made even more amazing by how often these giants are successful (note the blood on the bear’s muzzle).  In this particular image, I wanted to emphasize the bear’s size and strength, so I lowered myself almost to ground level before capturing the image.  The low camera angle made the bear look larger (as if that were needed) and more imposing.

The image was created using a Canon 1D mark 2, 500mm IS lens, at 200 ISO.  The lens was mounted on a Gitzo carbon fiber tripod with a Wimberly tripod head.
