Shot of the Month – August 2019

Wood Duck (5525)

This month we visit with a dandy of a duck — America’s own Wood Duck.  The male is supremely colored (per usual) — his head is adorned with an iridescent green and maroon crest while his face is deep purple with white stripes.  He also has a red bill, with another white stripe with a jazzy yellow patch at the base.  And that glorious red eye (ok, well, two red eyes).  But there is more Johnny!  His chest and rump are dark red while his back and wings are a shimmering dark blue-green.  There is even more, just check out the images to see it all — the drake wood duck is a paint-by-numbers dream come true!

Wood Duck (7422)

Of course all of this fancy dress is to attract the ladies — lady ducks that is.  These colors do not last year round however — once the breeding season is over, usually by early summer, the colors fade until next mating season.  In late summer the male grows gray feathers with blue markings.  The female wood ducks are much more humble in their coloration — they have gray-crested heads (no one ever said, “Oh look – Gray!!”), and generally covered in splotches of brown, gray-brown, and some white.  This coloration is quite sensible as it helps the females draw less attention to themselves and the chicks.  “Blah” is much better for blending and avoiding getting eaten.  Just sayin….

Female Wood Duck (7057)

Female Wood Duck

Woodies are cavity nesters — the female lays her eggs in an existing hole found in a tree.  This sounds like a reasonable plan till you realize that these holes are usually about 30 feet above the ground.  How do the chicks get down?  Elevator?  Nope.  One day after the eggs hatch the female leaves the nest and goes to the ground and calls to her chicks.  The chicks respond with peeping calls and climb up to the entrance of the hole and launch themselves outward to the ground.  Wow!

Check out this video to get a sense of how crazy this is.  (This video is of Mandarin chicks, but the idea is exactly the same).

Once they are all out mom leads the ducklings to water.  The female stays with the chicks and tries to keep them safe but does not feed them.  The ducklings are able to feed themselves from day one.  After about 8-10 weeks the chicks are fully feathered and can fly.

Interestingly, the diet of wood ducks changes as they get older.  As ducklings woodies dine primarily on aquatic insects.  As they grow to adults they shift over to a plant diet eating mainly aquatic plants, nuts and seeds.  Favorite food for a wood duck?  Acorns!!  Who knew??!!  In fact wood ducks have an expandable esophagus that allow them to swallow multiple acorns — one woodie was found with 30 acorns in his throat!

For those keeping score at home, wood ducks are “dabbling” ducks – dabbling ducks place their head under water while looking for food as their butts and feet stick up in the air.  Other dabblers include mallards, northern pintails and green and blue-winged teals.  Alternatively there are diving ducks, which well, you guessed it, dive and submerge completely below the surface of the water.

Wood ducks are, unusually for ducks, built for arboreal life as well as for life on the water.  Their feet are not only webbed, normal for a duck, but also have sharp claws, not so normal, which facilitate perching on tree branches.  The wings of wood ducks are also more broad than other ducks to make them more adept at twisting and turning in flight which is handy when navigating tight places between branches.  Woodies are most at home in wooded wetlands and along slow-moving, tree-lined rivers.  The don’t like open water.  Look for wood ducks around the edges of swamps, sluggish streams, overgrown beaver ponds, and wood-fringed marshes.  Check out the map below to find an acorn duck near you.

And speaking of odd names, other aliases for the wood duck include summer duck, woodie, Carolina duck, swamp duck and squealer (they can be noisy).

 

I have to say that I still find it odd to be out walking in the woods and look up to find a wood duck perched on a branch — just don’t seem right.  A duck.  In a tree.  One that eats acorns, no less.  Sounds like a bizarre duck/squirrel experiment gone horribly, albeit beautifully, wrong.  Oh well, get out there and find yourself an acorn duck – they are a wonderful sight to behold.

 

Until next month….m

Black Bear

Shot of the Month  Posted by / 0 comments

Shot of the Month – July 2019

Black Bear - Yellowstone (6831)

Heeeey BooBoo, did you know that we have three bear species that live in North America?  It is true.  We gots the Polar Bear, the Brown Bear (Grizzly) and Ursus americanus, aka the American Black Bear (ABB).  The ABB, is the smallest of the three bear species, is the most common, and can only be found in North America.

The ABB can be found in at least 40 states in the U.S. and ranges from Canada to Mexico.  It is estimated that there are 600,000 black bears in North America with half found in the U.S.  Black bears are typically found in forests where they can find a rich variety of fruits, nuts and vegetation.  Black bears may have originally gravitated to woodlands and thick vegetation to avoid larger more aggressive bears like the grizzly that tend to favor open habitats.   These bears are omnivores and their flexible diet allows them to live in a range of habitats including coniferous and deciduous forests as as well as open alpine habitats.

Up to 85% of the ABB’s diet is made up of vegetation which can include roots, grasses, fruits, berries, hazelnuts, oak acorns and whitebark pine nuts.  The majority of the bear’s animal diet is made up of insects like bees, yellow jackets, ants and their larvae.  And like Winnie the Pooh, they love honey and will rip apart bee hives for the tasty treat.  And depending on the location ABBs will hunt for fish (salmon, suckers, trout, catfish).  Black bears rarely hunt on large game but they will take the occasional mule or white-tailed deer fawn and may take elk or moose calves.

Despite their name, black bears can in fact be found in a variety of colors including brown, blond, cinnamon, rust and even white.  This color variation can cause some people to misidentify a black bear for a grizzly bear.  The size of black bears can vary dramatically depending on season and the availability of food.  Males typically range from 130 to 660 pounds while females typically come in at 90 to 175 pounds.

Black bears have relatively short, non-retractable claws that make them very good at climbing trees.  I photographed the female black bear above in Yellowstone NP in Dunraven pass where she was climbing whitebark pine trees to feast on the pine seeds.  Mom would climb the tree and bite off the pine cones and drop them down to her cubs below.  The large seeds, or nuts, of whitebark pine are a high-energy food rich in fats, carbohydrates, and protein. This makes them an important resource for bears (black, grizzly) fattening up in the fall before denning.  Unfortunately the whitebark pine is endangered and at risk for extinction.  Many of the causes of the decline of the tree are due to humans — the warming climate is allowing the mountain pine beetle to thrive and decimate the tree population.  Also, over the last hundred years humans have suppressed fires in yellowstone and in other alpine areas — turns out that fires were an essential tool in keeping forests diverse and robust.  You can learn more about this crisis here.

 

 

If you spend much time in the woods of the US or Canada you have a pretty good chance of seeing a black bear – fear not, black bears are generally not aggressive.  That being said, please give all wild animals ample space and admire from a safe distance.  Otherwise, you may just find Yogi and his brethren in your pick-e-net basket!

 

Until next month….m

The Beauty of Isolation

Shot of the Month  Posted by / 0 comments

Shot of the Month – June 2019

 

Tulip, Washington State (4028)

This month a photo of a tulip that demonstrates the power of isolating your subject to help create a compelling image.  In this shot there is no doubt about what this photo is about — our eyes can’t help but be drawn to that lone red tulip in the center of the frame.  In this image I used several techniques to isolate the subject:

Choice of depth of field

In this shot I used a very shallow depth of field (aperture of f/5.6) to ensure that almost all of the other flowers in this field were out of focus.  Our eyes are naturally drawn to the part of the image that is in focus.  For comparison look at the same image taken with a very wide depth of field (aperture of f/22).  In this version Tulip (4045)the field of flowers is more in focus and, at least for me, more distracting.  I find that my eye jumps around more from one part of the photo to the next and weakens the visual impact.  Click on the image to see it larger.  Here is a primer on understanding depth of field.

Point of View (POV)

To get this image I shot while crouched on my knees to get a low angle — this allowed me to shoot up and through the red flowers in the foreground and create depth in the image.  This POV also allowed the red tulip to appear higher into the field of purple in the background and helped create more separation and space between the subject (red) and the foreground (red).  Don’t be afraid to move around and explore the scene to make sure you are including the elements you want in the shot, and perhaps even more importantly, explore how your POV can help remove elements that weaken your image.  Try higher.  Then lower.  Move to the right.  To the left….shake it all about….

Contrasting Color

I was immediately drawn to this scene by how the red tulip popped visually against that purple background.  The lovely green stem of the subject also adds more contrast and leads the eye to the subject.

Centered Subject

Tulip (4041)

Landscape orientation is not as compelling for this shot

While it is often not recommended to center your subject it can sometimes be a useful technique under the right circumstances (See my post here on this topic).  I usually try multiple compositions with the subject to the left, right and centered to help find what works best for the scene.  I also often shoot in both landscape and portrait orientation to see which leads to a stronger composition.  Given the vertical nature of the flowers portrait orientation worked best.

 

Wow, so much to consider to just get a pretty picture of a flower!  These are in fact just a few of the ways that one can isolate the subject of an image.  What are the others?  Hmmn, that sounds like fodder for a future post….I just need to get outside and get the shot….stay tuned.

 

Until next month…m

Rufous-ly Ruthless

Shot of the Month  Posted by / 0 comments

Shot of the Month – May 2019

Rufous Hummingbird, Washington State (4184)

A Rufous male warning me off with a flash of his gorget.

This month we visit with the glorious Selasphorus rufus, aka the Rufous Hummingbird.  For those of you who are a bit rusty on your color palette (I was):

Rufous:  reddish brown in color.

So while the name is not terribly creative it is accurate.  The male Rufous is adorned in reddish brown on the crown, tail and sides.  His back can be rufous, green or a bit of both.  But the pièce de résistance for the male is that flame-orange gorget.  Gor-what?  It is a term that refers to the piece of armor that knights wore to protect their throats.  It now refers to the patch of color that can be found on a bird or animal. The intense glint of the gorget is the result of iridescence, rather than colored pigments. The bird’s throat feathers contain minutely thin, film-like layers of “platelets,” set like tiles in a mosaic against a darker background. Light waves reflect and refract off the mosaic, creating color in the manner of sun glinting off oily film on water.  The color and intensity of the gorget changes depending on your angle of view.  (Source)  The female Rufous is not nearly as flashy — she typically is greenish above with rusty-washed flanks, rusty patches on her green tail with a spot of orange on her throat.  (Source)

In researching the Rufous I was surprised to see how often the word “fiesty” came up.  One article said that the bird was “well known to be incredibly feisty and pugnacious.”  As far as hummingbirds go the Rufous is considered to be on the small side, usually between 2.8 to 3.5 inches and weighing about 3.5 grams.  For comparison a US penny weighs about 2.5 grams!  Apparently no one told the Rufous — they are commonly considered the most aggressive of the hummingbird species!  As one literary-minded observer noted:

“The male Rufous, glowing like a new copper penny, often defends a patch of flowers in a mountain meadow, vigorously chasing away all intruders (including larger birds).” (Source)

Ever have a Rufous at your backyard hummingbird feeder? Yikes — I can tell you from personal experience that they defend those feeders with equal zeal.  They drive off other hummingbirds, bees, wasps, birds and other insects without respite.  I had one hover 2 inches from my face trying to scare me off.  We eventually set up more feeders around the house to try and give the other hummingbirds a chance at some food.

Rufous Hummingbird Range (Source)

Like other hummingbirds the mainstay of their diet is protein and sugar.  They get their sugar by feeding on the nectar from colorful, tubular flowers which they access with their long extendable tongues.  Preferred flowers include columbine, scarlet gilla, penstemon, indian paintbrush, mints, lilies, fireweeds, larkspurs, currants, and heaths.  The flying pennies get their protein and fat by catching insects like gnats, midges and flies in the air.  They will take aphids off of plants also.  Given their frenetic lifestyle they consume three times their body weight in food each day.  The Rufous has a fantastic memory that helps it find flowers and feeders along its long migration route from previous years. (Source)

Speaking of which, the Rufous hummingbird has the longest migration of any hummingbird — they can fly up to more than 2,000 miles in one direction from the northwest United States down to Mexico and the Gulf Coast where they winter. While the Rufous hummingbird is found predominantly in the western US this far ranging bird has been spotted in every state except Hawaii.  These guys get around!!

 

I can’t help but admire this little bird — the Rufous is a real beauty to behold, is a tremendous athlete, has a sharp mind, and has the fighting spirit of a heavy weight boxer – all rolled up into a thimble-size body!

 

Until next month…..michael

Shot of the Month – April 2019

Jaguar, Pantanal - Brazil (0578)

This month we visit with the most powerful cat in the Western Hemisphere — the Jaguar.  This heavyweight of the feline world is the third largest in the world, coming in just behind the Lion and then the Tiger.  The jaguar is the only member of the “Big Cats” that is found in the Americas.  I photographed this jaguar in the Pantanal, in Brazil.

Looking like a heavyset leopard these cats are built for life in the tropical rain forest where they are found — they have muscular limbs and large paws which allow them to climb trees and swim rivers with ease.  Unlike most felines, these cats absolutely love the water and rarely stray too far from the river.  That being said, they are adaptable and can be found in other habitats including grasslands and deserts.

The jaguar is a stalk-and-ambush hunter unlike lion and cheetah which chase their prey.  These cats walk slowly, and silently through the jungle in search of a meal.  They also walk along the river’s edge, or even in the water as seen in my image above.  We watched this impressive male, known locally as Mick Jaguar (Groan, I know.  It doesn’t seem as corny when you are there seeing this incredible cat….) hunt along the river for several hours.  Even though Mick is past his prime now, perhaps 11 years old, he is still the top cat in this part of the river.  You can see that his one eye is injured but we were told that he can still see with it.

Medium-sized mammals make up the majority of Mick’s diet and can include deer, capybara, Peccaries, and Tapirs.  When hunting in the water prey may include turtles, fish, and caiman (a relative of the crocodile and alligator).  In total Mick and his brethren can take over 85 species depending on what they can find.   One of the few jaguars that lived in the US was known to even kill and eat American black bears.  (source)

Like most big cats Mick kills large prey with a deep throat bite that suffocates the animal.  Jaguars have the most powerful bite of any cat and sometimes kill their prey by biting through the animal’s skull!  When hunting large caiman the jaguar will sometimes jump on the back of the reptile and bite through the base of the skull and sever the cervical vertebrae which instantly paralyzes the animal.

Blah, blah, blah.  So many words.  Watch this unbelievable video of Mick himself on a hunt from several years ago– this video will show you everything you need to know about the hunting style of the jaguar, their fearless nature, and their lethal hunting techniques.

Any questions?  WOW!

 

Until next month…..m
