Flashback Post XI

After all the negative things that I have said about President Trump, I thought I should contribute to his fear-mongering when it comes to immigrants.  I have thus provided a link to a worrisome post from July of 2007. See: Armored Immigrants

The Beaver Moon

November's full moon, currently brightening the night sky, is commonly known as the "Beaver Moon," a designation attributed to the Algonquin Tribe and now imbedded in American folklore.  The name reflects the fact that beaver are especially active at this time of year, repairing their dams and lodges and storing food for the winter months.  The latter usually consists of small deciduous trees and limbs that are placed underwater for sustenance while ice coats the stream or pond. My wife and I, frequent visitors to Philips Lake in southeast Columbia, have recently noted extensive beaver damage to small trees along the 40-acre lake.  Once a farm pond, the lake is stocked with fish by the Missouri Department of Conservation and the surrounding land was dedicated as the A. Perry Philips Park in 2011.  This is the first year that we have noticed the beaver damage and have been surprised that these large rodents made their way up from the nearby Gans Creek Valley. If left ...

Companions on the Trail

Veteran naturalists, despite decades in the field, often encounter species or animal behavior that they had not observed in the past.  Indeed, it is this expectation that keeps us interested and attentive, drawing us into natural ecosystems throughout the year. This morning, while I was birding at the Columbia Audubon Sanctuary, I heard a noise behind me; turning to look, I discovered six young white-tailed deer, standing at attention.  As I continued to make my way across a sunny hillside, the deer followed at a safe distance, stopping to browse when I stopped to scan the landscape with my binoculars.  This pattern continued for a quarter mile or so before they seemed to lose interest and wandered into an adjacent meadow. I suspect they were recently abandoned by their newly pregnant mothers and banded together for comfort.  No doubt, I was a mere curiosity and, having spent their short lives in a nature sanctuary, free of hunters, they had no reason to fear an agin...

A Wounded Hunter

As I walked along the South Platte River on this bright but chilly morning, I spotted a coyote on the opposite bank, nosing his way through the thickets.  It soon became apparent that he had injured one of his back legs and could not bear weight on that limb. While we are entering the season when predators generally have an advantage (leafless foliage, dry grass and active prey), I wondered if this wounded hunter will make it through the winter.  No doubt, it will be harder for him to chase down rabbits and other agile prey. Then again, coyotes are intelligent and highly adaptable creatures, adept at surviving in remote wilderness as well as in rural and urban environments.  Known to take advantage of human garbage and dog food, they also feed on carrion, berries and domesticated animals in addition to a host of wild birds and mammals.  My bet is that he'll manage just fine. 

Pink Egrets at Dusk

Last evening, I went out at dusk to explore our Littleton farm.  Most of the bird sightings were of mallards, great blue herons and ring-billed gulls, heading toward their nightly quarters to our northwest. A squadron of small bats strafed the farm and our colony of cottontails emerged for a leisurely night of nibbling.  Off toward a corner of the property, a noisy flock of magpies had gathered in a tree, apparently heckling a hawk or owl.  Above it all, jets drifted toward DIA and the clouds took on the changing hues of sunset.  Not to be outdone by Earthly events, Jupiter gleamed from the southwest while Saturn sparkled in the southern sky. The highlight of my evening stroll proved to be a flock of pink egrets, fourteen in number, flapping toward a roost somewhere north of the farm; of course, they were snowy egrets, painted by the last rays of the setting sun.  Apparently unfazed by the cooler weather, they will spend at least another day along the Front Rang...

Autumn Chill in the Valley

While the afternoons are still summer-like along the Colorado Front Range, the mornings now bring an autumn chill due to the longer nights.  Down on the South Platte River just after dawn, that chill was especially intense and, in response, the wild residents were noisy and active. Canada geese, mallards, magpies and cedar waxwings were especially conspicuous and migrant ducks were beginning to arrive from the north; this morning's visitors included blue-winged teal, American wigeon and gadwalls.  A few summer residents still remain and a lone snowy egret, huddled on driftwood in the shallows, seemed to be contemplating his escape to warmer climes.  Normally nocturnal, a beaver was active in the post-dawn chill, inspecting his dam before winter arrives. We humans, like the wildlife, are also invigorated by the chilly air and the riverside path was filled with walkers, bikers and joggers.  After all, the fall equinox arrives this weekend (September 22) and the gloriou...

River Otter at Eagle Bluffs

On this pleasant morning in central Missouri, a friend and I headed down to Eagle Bluffs Conservation Area, on the Missouri River floodplain.  Bird sightings were far from spectacular though a large number of great egrets and great blue herons were encountered.  The highlight of this morning's visit was the sighting of a river otter, feeding in a channel at the south end of the refuge. Nearly extirpated from Missouri in the early 20th Century, river otters have made a dramatic comeback due to a reintroduction program that began in the 1980s.  Now found in rivers, large creeks and lakes throughout the State, these large mustelids feast primarily on fish, crayfish and amphibians; the young are born in late winter and family groups may be found throughout the year. Since river otters are primarily nocturnal, they are not regularly observed by the general public and are more abundant than most of us might suspect.  This morning's sighting was thus a special and unexpecte...

Encountering the Red Tide

Since we had a wedding to attend in South Carolina in mid August, we decided to spend the second half of this month at our condo on Longboat Key, Florida.  Unfortunately, in the weeks leading up to the wedding, we learned that a severe and persistent red tide had developed along the coast of Southwest Florida.  Nevertheless, we decided to investigate for ourselves. A toxic algal bloom of Karenia brevis , a red tide results in extensive fish kills, littering the beaches with rotting fish; a neurotoxin released by the algae may also kill dolphins and manatees and, this year, the corpse of a whale shark washed ashore.  In addition, particulate debris from the abundant algae wafts in on the sea breeze, causing eye, throat and lung irritation for those humans who do not abandon the region altogether. We arrived to find that the dead fish odor was indeed strong along the beaches but that the wind-blown irritants were rather mild.  Though we will likely depart earlier than ...

Death on the River

Due to the hot, dry weather (and primarily due to reduced water release from upstream reservoirs), the South Platte River was very low this morning, attracting a variety of waders and shorebirds; among these were great blue herons, snowy egrets, black-crowned night herons, killdeer and spotted sandpipers. While focusing in on one of the great blues, I watched as he suddenly jabbed into the tall riverside grass and turned back with a small mammal in his formidable bill; too large to be a field mouse, I suspect it was a meadow vole or a young muskrat.  After dipping it the river to moisten the fur, the heron tilted his bill skyward and swallowed the victim in a single gulp; he then resumed stalking the shallows for his next snack. Though we often watch herons and egrets in wetlands and along shorelines, feasting on small fish or aquatic invertebrates, we are undisturbed by their natural activity.  But when a large heron grabs a small mammal and swallows it whole, we empathize wi...
