Wilson's Snipe - A Feathered Phantom

Image
The Wilson's Snipe The reclusive Wilson’s snipe lives in North America but you'd be lucky to ever lay eyes on one. Because of his secretive nature, he’s most active around dusk and dawn while preferring to sleep much of the daytime. When he's awake this plump, little shorebird uses his long, flexible bill to probe in the mud for larvae and earthworms. His unique mandible can move independently upwards allowing him to swallow small prey without having to pull his bill out of the dirt. The Wilson’s snipe is mottled brown overall with a white belly and streaked breast. Dark stripes decorate his head and back. He makes his nest in the wetlands where his drab plumage blends perfectly into the dried, cattail willows. His bill is outrageously long and his eyes are set so far back on his head that he can see not only in front and to the sides but also completely behind. He has short legs and massive flight muscles so when he’s flushed from his safe haven he can explode i...

Spotted Towhee - A Hefty Sparrow

Image
Spotted Towhee Rustling through the leaf litter below the dry scrub brush that laces the steep, Colorado foothills is where you’ll find a hefty sparrow known as the spotted towhee. Such beautiful birds, the males have a white belly, orange sides and a black head, throat and upper parts. The back and wings are flecked with white spots while the red eyes are the defining characteristic. During the early spring, those males creep up to the top of the thicket and sing all day long while trying to attract a mate. In the breeding season they eat mostly insects but they’ll also dine on acorns, berries and seeds. They’re nest cup is built deep inside a sharp briar and usually concealed somewhere near the base of the shrub. A close cousin, the eastern towhee, used to be considered the same bird as the spotted towhee and in the past they were called the rufous-sided towhee. During the last ice age large ice sheets split the continent down the middle, isolating the separate birds into ea...

A Talk with the Woods - Learn How to Listen

Image
A Talk with the Woods “Go sit under a tree and listen and think.” ~ Walt Whitman This week's post is written by my uncle, Jerry Covault. Jerry is a retired United States Forest Service Ranger. During his 33 years spent working on National Forests in Oregon, Colorado, Wyoming and Montana, he has learned about the relationships between mountains, forests, soils, weather, fire, animals and people. Jerry shares some of his unique experiences in his new book "About Forests and People". He resolves to stimulate interest and curiosity about trees and forests and how people use them both through the ages and at present time. Jerry also discusses the problems our forests and environment have today and he suggests a few things that can help. The following essay by Jerry Covault is taken from his book "About Forests and People". A Talk with the Woods Fragment: From the Alfoxden Notebook (I) And never for each other shall we feel As we may feel, till we ...

Cyborgs - They are Walking Among Us

General Grievous "I am Grievous, warlord of Kaleesh and Supreme Commander of the armies of the Confederacy. And I am not a droid" ~ Grievous I've always been fascinated by science fiction stories. I'm allured by the exotic locales, strange creatures and the wondrous but sometimes unsettling human characters that are portrayed as a synthesis of organic and artificial parts. People like the Six Million Dollar Man, Robocop and the Terminator raise questions about the differences between man and machine concerning morality, free will and empathy. My favorite cyborg has to be General Grievous from the Star Wars saga. Not only because he's artistically cool but he's also a battered old warrior living precariously to fight another day. After a bomb destroyed his shuttle, Grievous suffered near fatal injuries that rendered his body useless. The Separatists reconstructed Grievous by implanting his brain, eyes and vital organs into a duranium alloy body. Grievo...

The Eternal Mystery of the Human Heart

Image
The human heart is a mystery "When we understand every single secret of the universe, there will still be left the eternal mystery of the human heart." ~ Stephen Fry Ancient Greek philosophers identified the human heart as the primary spiritual feature and most important organ of the human body. It was the source of intelligence, motion and sensation. From the heart alone, emotions like anger, passion, fear, terror, sadness, shame, delight and joy were derived. Because the heart functions at the center of the blood delivery system, it's also central to life. The heart speeds up and slows down automatically in response to nerve signals from the brain. Each heartbeat fills the four chambers inside with a fresh round of blood. The upper chamber on each side is called the atrium while the larger, more powerful lower chamber is the ventricle. They keep the body freshly supplied with oxygen and nutrients, as well as clearing away harmful waste. More than just a mec...

King Cobra - An Intelligent Icon

Image
King Cobra King cobras live mainly in the rain forests and plains of India and Southeast Asia. They are comfortable in the trees, on land and in water, feeding mostly on other snakes with the rat snake being their preference. King cobras can reach 18 feet in length, making them the longest of all venomous snakes. Fortunately for us, they are reclusive creatures that will make every attempt to avoid humans. When confronted, though, a king cobra transforms into a lethal adversary. It can raise a third of its body straight off the ground, looking the average person directly in the eyes, and still advance forward to attack. The intimidating snake will flare out its iconic hood and produce a frightening hiss that sounds a lot like a dog's growl. A single bite contains enough venom to bring down an elephant. Scientists are just now beginning to understand how intelligent these snakes really are. The king cobra is believed to possess exceptional memory. According to a myth, the p...
