Jungle Cat

Shot of the Month – December 2019

In 2019 I visited the Pantanal in Brazil to photograph jaguars and other wildlife – you can see the highlights in this video.  En route to the prime jaguar location we spent one night at small lodge where we saw another wild cat of the region – the Ocelot.  Each night the lodge puts out chicken to attract this rarely seen cat.  I am not a fan of baiting wildlife as it can diminish their survival skills and promote dangerous human – wildlife interaction.  For what it is worth this cat does not show up every night and it seems that he is not dependent on this food supply but only drops in when he wants a supplement.  Or perhaps only when he is in the mood for a bit of chicken….

As you can see Ocelots are fairly small, coming in at about twice the size of an average house cat or roughly the same size as a bobcat.  The males can grow to about four feet in length while the females are usually about two and half feet long.  Ocelots tend to weigh between 28-35 pounds.

These solitary cats are highly nocturnal and use their exceptional eyesight to hunt rabbits, rodents, snakes, fish, frogs, young deer, peccaries, iguanas and other lizards.  They are good swimmers and good climbers so they will hunt for fish in nearby streams while also stalking monkeys and birds in the trees.  Ocelots hunt by walking slowly along game trails hoping to ambush their prey.  They are also “sit and wait” predators, sitting motionless for 30-60 minutes at a den or burrow site.  If no luck they move quickly to another site and sit and wait again.

Ocelots can be found from southwestern United States to northern Argentina.  These cats thrive where plant life is dense and can be found in tropical forests, thorn forests, mangrove swamps and savannas. There are about 800,000 to 1.5 million Ocelots remaining in the Western Hemisphere but their numbers are declining.  In the US Ocelots were once found in southern Arizona and throughout much of Texas, and even reaching Arkansas and Louisiana.  Alas, human development in these areas has caused Ocelot numbers to plummet and they are now at risk for extinction in the US.  Today they can only be found in southern Texas with only about 40 individuals remaining.  In Colombia, Argentina and parts of Brazil the cat is listed as vulnerable.

The fur trade in the 1960s and 1970s was devastating to the Ocelot population – in 1970 alone over 140,000 Ocelot skins were traded in the United States.  Fortunately most countries now ban the trade of Ocelot skins.  While the threats from the fur trade, hunting, and the pet trade have reduced other threats are growing.  The loss of habitat and fragmentation of habitat is a major threat as us humans continue to expand our footprint across the planet.  Traffic accidents are a growing threat as Ocelots are increasingly hit by cars as new roads crisscross their shrinking habitat.  Logging and poaching of their prey species are additional threats to their survival.

Although these lovely cats are rarely seen our world would be much poorer without their nightly jaunts through the jungles of our dreams and fables.  Let’s hope that we can find a way to allow the Ocelot to roam our jungles for many years to come.

 

Until next month….m

Sailing into History

Shot of the Month – November 2019

Peter Iredale, Oregon (HDR 4397)

While this ship is clearly no longer sea worthy its rusting hull can, at least for a few more years, take our imagination on a journey back in time.  The hull, located on the beach at Fort Stevens Park,  is all that is left of the Peter Iredale, a four-masted steel barque that ran aground on the Oregon coast on October 25, 1906.  The ship had departed from Salina Cruz, Mexico (about 60 miles south of San Diego) a month earlier bound for Portland, Oregon with 1,000 tons of ballast and a crew of 27.  Nearing the end of its journey the ship encountered a fierce storm just four miles south of the Columbia River channel and was driven onto the beach in the driving winds.  The force of the impact was so great that 3 of the 4 masts of the ship snapped when it hit the sand.  All crew were rescued from the ship and there were no casualties.

Above we can see the Peter Iredale in all his glory — the steel ship was built in 1890 in Maryport, England and was 285 feet long.  The ship was sent to Portland to pick up a cargo of wheat that would be sailed to England.  Below we can see the ship not long after it ran aground.

There was little damage to the hull so initially the plan was to tow the ship back to sea.  However, the recovery team had to wait a few weeks for favorable weather and during this time the ship sank deeply into the sand and it was impossible to move it.  And so there it has stayed for the last 113 years.

And, in case you were wondering:

Who the heck is Peter Iredale?

He is the bloke that owned the ship.  He had a shipping firm called Iredale & Porter and was a business big shot in Liverpool, England.

Did the crew screw up and cause this mess?

Well, a naval inquiry was held by the British Vice-Consulate to determine the cause of the wreck.  The British Naval Court ruled that the sudden wind shift and the strong current were responsible for the stranding of the ship, and that the captain and his officers were “in no wise to blame” and in fact the captain (Captain H. Lawrence) and the crew were commended for their attempts to save the ship.

I only spent one afternoon at the wreck site and as luck would have it, there was a low tide near sunset allowing me to walk right up to the hull.  Here a few images from different perspectives and as the light transformed as the sun went down.

Here is a landscape orientation as some clouds rolled in:

As the sun nears the horizon the light weakens but there is a soft pink hue (alas, we lost most of those lovely clouds):

Here we can see the full side of the remaining hull in the last light:

On that fateful day, just before leaving the beach, it is reported that the red-bearded captain stood stiffly at attention, saluted his ship, and said:

May God bless you and may your bones bleach in these sands”

He then turned and addressed his men with a bottle of whisky in his hand. “Boys,” he said, “have a drink.”

I don’t know if this salty tale is all true, but I like to believe that it is.

 

Ayyye!  Until next month….m

Pied Kingfisher

Shot of the Month – October 2019

Pied Kingfisher, Kruger NP (7606)

There are 114 species of kingfishers around the world and most are bright splashes of color with wings.  These small to medium size birds tend to specialize in catching fish though a few prefer insects.  All tend to have large heads, long, sharp pointed bills, short legs and stubby tails.  One of the most common kingfishers is the Pied Kingfisher as seen above.  Bright splash of color??  It seems that the Pied Kingfishers were at the back of the line when the colors were given out as they are rather penguin-esque decked out in their monochromatic black-and-white color scheme.  Click here to see a more colorful variety.

As shown below, Pied Kingfishers are exceptional hoverers — by flapping their wings rapidly they can stay in one place for an extended period time as they scan below looking for fish in the water.  They are actually the largest bird that can truly hover.  While hovering they have to keep their head perfectly still to judge the location of the fish below.  Here is a great video that explains the hunting technique of these skilled fliers.  And another good video here.

A fresh kill captured on film….Definitely will NOT need a bigger boat for this one.

The Pied Kingfisher can be found throughout sub-Saharan Africa and southern Asia from Turkey to India to China.  I photographed this lovely chap in Kruger National Park in South Africa.

The Pied Kingfisher – what they lack in color they make up for it with true acrobatic talent and classic formal style and grace.

Love in the Air?

Shot of the Month – September 2019

Lion (4675), Kruger NP, South Africa

So what’s going on with this big ol’ male lion?  Is he snarling?  Is he about to sneeze?  Did he get a whiff of a stinky warthog?

All good guesses, and thanks for playing along, but all incorrect.

What we got here is a good example of the flehmen response.  Uhhhh, the flaming what?

The flehmen response —  in German flehmen means to “bare the upper teeth.”  Ok, that seem accurate, Simba here is indeed baring his upper teeth.  So we got the “what,” how about the “why”?

Well, many animals exhibit this behavior to draw in air to reach a specialized organ above the roof of the mouth.  This organ has specialized receptors to detect pheremones, scents  and other chemicals.  This organ is called the vomeronasal organ or Jacobson’s organ (Ludwig Jacobson described the organ in 1813, even though Frederick Ruysch found it first in 1732).  The vomeronasal organ is connected directly to the brain and allows the animal to better assess potential prey animals, predators and potential mates.  This process is distinct from smelling and engages a completely different pathway to the brain.

Some animals, like cats and horses have to raise their lips to allow air to reach this specialized sensor.  Other animals, like elephants can access their vomeronasal organ without the lip curl (Thank You Very Much).  Flehmen is demonstrated by most of Africa’s ungulates and predators including giraffe, rhinos, buffaloes, lion, leopards, cheetahs and other cats.  Fun fact:  Hippos can do the flehmen response underwater!  Jacobson’s organ is also found in all snakes and lizards, dogs, cattle, pigs, and in some primates.  Snakes use the organ to sense prey — they stick their tongue out to collect scents and then touch their tongue to the opening of the organ when the tongue is retracted.  Humans do not have this specialized organ.  Both males and females can demonstrate the flehmen response.  For example female sable antelope use flehmen behavior to allow them to synchronize conception and birth of their offspring in a herd.

The male lion above, photographed in Kruger National Park in South Africa, wrinkled up his nose after his lady friend walked over to say “Hi.”

And she gave him a friendly head nuzzle:

After this the male stood up and checked to see if “love was in the air.”  For the non-romantics:  He triggered the flehmen response to draw in air to see if the female was emitting pheremones that would indicate that she was receptive to mating.

 

Love….flehmen…a rose by any other name would smell as sweet…..

 

Until next month….m

Woodie

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 (6205)

 

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.

Wood Duck Range Map (Source)

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
