Ways to Connect

Velvet Ants

Oct 17, 2016

Boys are impressionable creatures.  They hone in on pronouncements that combine adventure and danger.  Such was my experience many years ago when I was warned by elders to avoid at all costs an insect with the moniker "cow killer."  How could such a beast in our midst not be a call to action?  It was claimed that the sting was so terrible that it could dispatch a healthy cow.  I set out to catch one in a Mason jar.  

Balloon Releases

Louisiana.  Across the country we are known for our moss-draped cypress trees, slow meandering bayous, antebellum homes, spicy cooking... and litter.  In spite of our wonderful assets, our litter liability is one thing most visitors remember.  Everyone is impacted.



Oct 3, 2016

That humans are increasingly impacting the natural world is beyond question.  Our influence often comes by way of odd and sinuous paths.  Consider that the presence of one very common but non-native and often harmful bird species in Louisiana can be attributed to William Shakespeare.


Heartwood Doe

Sep 5, 2016

Here on this property where we live and that we call Heartwood, there is an unwritten game law.  It is "thou shall not hunt within a quarter-mile of the house."  The doe that browses just outside my home office window at noon has tempted me on occasion to propose an amendment to this family statute.


Fish Migration

Aug 29, 2016

Even the most nature-deprived urban dwellers among us are aware of the basic concept of bird migration.  They know that some types of birds fly north in the spring and return in the fall.  However, few people including most outdoor-oriented folks in this region who should know better realize that migration is also a vital part of the life cycle of other kinds of local wildlife.  Consider freshwater fish, for example.


A few days ago while driving through the D'Arbonne Swamp north of West Monroe, I was treated with a stunning sight.  I caught a glimpse of a large animal ahead on the road shoulder, and my first impression was that it must be a hog.  As I got closer it became obvious that it was a bear - shiny black and beautiful in the early morning light.  He wheeled and ran down the road bank, across a shallow ditch, and into the D'Arbonne National Wildlife Refuge.  Until recent years this encounter would have been nigh on impossible.


Red Wolf

Aug 17, 2016

John James Audubon's son, John Woodhouse Audubon, was a pretty good artist in his own right.  When the elder Audubon began showing signs of mental illness toward the end of his career, his son stepped in to complete their famous portfolio on American mammals.  The topic of the day is the younger Audubon's Plate No. 82 from the year 1845 and depicts a wolf standing on a sandbar in a Texas river, sniffing a bison horn surrounded by scattered mussel shells.  He labels it the "Red Texan Wolf."  The status of this animal is headline news today.


Whirligig Beetles

Jun 13, 2016

A boyhood on the edge of a Louisiana swamp is fraught with danger, some real but most imagined.  An example of the latter occurred when as adolescents my neighborhood gang would gather at the White's Ferry Bridge to swim on hot, summer days.  The event began as we jumped from the high bridge into Bayou D'Arbonne below.  The older boys always warned us of an instant death that would befall us should we be so unfortunate as to do a belly-buster from that height.

Thyroid et al.

Jun 6, 2016

A recurring theme in this Bayou-Diversity program involves our connections and links to the natural world.  For today's show consider this hypothetical scenario.  A young couple decides to celebrate their anniversary by dining out at a popular seafood restaurant on  a warm spring evening.  The special of the day is stuffed flounder, which they both choose to try along with a side order of fried frog legs as appetizers.  When their dinner is served it is sprinkled with salt to embellish the rich natural flavors, and the meal is indeed memorable.

Pallid Sturgeon

May 30, 2016

For a very long time, 70 million years or so, a strange sort of fish has been swimming along the sandy bottoms of North America's largest rivers.  They have neither bones nor scales.  Instead they have a cartilaginous skeleton and rows of bony scutes for protection.  An elongated snout, asymmetrical, scimitar-shaped tail, and whisker-like barbels add to their bizarre appearance and reputation as living fossils.
