Broad Hawk Down

There are many things I expect to see when I walk out onto my Dollar Lake Dock.  I am usually content with the verdant green vista offered by Lily pads, Green Darners, and Green Frogs. I always anticipate something out of the norm, however, and this is what drives my repeated mini-ventures to the end of the crooked pier. This past weekend a splash and movement of brown caught my immediate attention and I anticipated that the local muskrat was making his rounds. When the subject displayed a fan of tail feathers it took a quick reassessment to conclude that I was looking down at a small hawk. The bird was floundering among the lily pads north of the dock. Spread winged and groping for support, it could not make any headway and appeared trapped and fatigued.

I grabbed a hand net, dragged my kayak to the water’s edge, and paddled out to the hapless raptor. The bird offered no resistance when I scooped it out. Rather than set it down on the boat’s bottom (between my legs, I might add) I opted to hold the net up with one hand and operate the kayak paddle with my other hand. Negotiating the thick vegetation cover, my efforts resembled those of a two-legged daddy longlegs and I felt for the struggles of the bird I now held captive.  My wife was able to pull me in the final paddle length to the dock and the clumsy rescue was completed.

Apart from being very wet and exhausted, the hawk seemed to be un-injured. An occasional spurt of liquid issued out of its mouth, indicating that it had swallowed some water, but still I hoped for the best. A quick dry off, assisted by a blow dryer, restored the fluffy down feathers and the overall form of an immature Broad-winged Hawk emerged from the sodden mess. The only remaining thing for me to do was to set it down in the shade of a Red Maple and give it time to recover. Three hours later it was dead.

In a Disney world, this story would have ended with a full recovery and a tearful goodbye. Instead, I was merely witness to a real world fact of life -which is death. Nearly 80% of young raptors die within their first year of life. Few of us are present during nature’s grim reaping process and must take solace in seeing the lucky 20% fly overhead. Upon leaving the care of the adults, the youngsters are subject to a steep learning curve where they have to master the combined arts of hunting, flying and decision making. A small error can be fatal.

This Broad-wing was probably a product of a brood raised this past spring in the woodland on the opposite shore of the lake. These small bodied forest hawks frequent habitats near water and feed upon a wide range of prey. Amphibians and rodents make up a large part of their diet, but they will consume small birds and insects at will. It is my guess that it was a tasty green frog that lured our unfortunate youngster into the drink by my dock. The frogs typically slip out of the shallow water and sit upon the pads like so many garden ornaments. The field of lily pads is continuous in the zone within twenty feet from shore and it appears like a solid mat from above. Upon missing the mark, the hawk likely found itself ensnared in the greenery as each pad acted like a trap door.

The unfortunate bird probably would have been dead within the hour had I not arrived – sinking to the bottom and serving as food for countless bullheads and turtles. I merely delayed and shifted the final resting place to a patch of shaded ground where flies and raccoons will process the remains.

One Pic Post: Air Mail

Filed under: Animals,BlogsMonroe — wykes @ 2:57 pm

Although few and far between this spring, a scattering of nice spring days have bubbled up to the surface. On such days, the sun takes the edge off the cool winds enough to call them refreshing – as opposed to the de-fleshing blasts of unfriendly days. Newly hatched spiders, blossoming maples, swelling cottonwood buds, and short-wearing youth clad with heavy coats signal the return of reasonable weather.

It would normally be my preference to focus on the cottonwood or maple flowering part of the season, but since I’ve already addressed them in the past it was a choice of youth or spiders. So naturally I gravitated to youthful spiders. Actually it was trip across the road to get the mail that prompted this post (my first in half a year due to an onset of “authoritus” – meaning the writing of a book and not writer’s block).

Astride the top of the mail box, a tiny spiderling barely 2 mm across scrambled to the highest point. There it paused before assuming a tripod stance and lifted his abdomen high into the air whenever a gust of wind fluttered by. It was attempting to deliver itself as air mail unto the mercy of the postal breezes. I was struck by the ironic mix of duty and place.

Unseen to my naked eye, and to the camera lens, the potential pilot sent out a series of two or three long radiating silk threads from its spinnerets at the tip of the abdomen (thus the stance).  These lines will be grabbed by the wind and eventually lift the tiny cargo aloft. Scientists call this method of travel “ballooning.” It is a primary means of dispersal for young spiders. We are not sure what the spiders call this procedure, although the fictional Charlotte would have been able to write it out in her web. Like the babies in “Charlotte’s Web” my micro-arachnid was seeking new ground via the magic of free air.

Ballooning is a risky means of travel since the spider has little control over its fate once pulled into the air stream. After all, we all know the story of the hapless professor who started his balloon in Kansas and ended up in the Magical Land of Oz. Most spider flights take the passenger a few dozen yards – enough to get it away from its fellow spiderlings and onto new hunting grounds.  Frisky gusts, however, can take a spiderling for miles horizontally or vertically and turn them into what has sometimes been referred to as aerial zooplankton. Certainly some end up tangled in maple flowers, upon swelling Cottonwood buds, and even onto the purple hair of a short-wearing youth clad in a heavy coat.

I do not know the fate of my spiderling because it failed to launch after several attempts. To spare it further embarrassment I left it alone and now imagine that the wee spider ended up in Oz.

Whale Watching for Loons

Filed under: Animals,BlogsMonroe — wykes @ 8:39 pm

Lake George is a sizable body of water located just south of West Branch, Michigan. Like many small northern lakes it presents two faces during the summer. It becomes a boiling pot of motorboats and Jet skis during the weekend, thanks to the public launch, and a slew of private residences populating half of its shores. The other half of the lake is bordered by wild lands, however, and for most of the week it is calm and serene.

Two of the lake’s residents, a pair of Common Loons, are tied to this wild side and are the epitome of wildness themselves. It is hard to image how the birds put up with all the hub-bub – perhaps they leave for calmer waters during peak activity and then return after the last wakes die down. One could imagine that such birds would be a bit on edge.  Imagine my surprise when a recent encounter with these Loons was both up close and personal.

When my wife and I first pushed out into the Lake George water with our kayaks there was no sign of life.  The weekend boaters were gone and the lake surface was as glass reflecting a clear blue summer sky. As if entering the world for the first time, a loon magically popped up out of the water immediately ahead of my kayak. It eyed me severely and I expected it to immediately disappear from whence it came – never to be seen again. Indeed it did dive again but bobbed back up in the same place. It continued to do so as if we were not present.

Another bird soon joined in, also appearing to ignore our presence, and the two cavorted about, around, and under our kayaks for well over 20 minutes. Both birds were actively fishing and engaging in completely normal behavior. Swimming with their heads dipped under the surface they eyed the depths for quarry before taking a plunge. Every now and then one would open up it’s wings and send a spray of golden water droplets into the air.

It was impossible to tell where they would pop up again after a dive and, more often than not, they’d surface even closer than the point at which they disappeared.  The only wildlife viewing experience I could equate this to was whale watching off the coast of Maine. Although the scale was dramatically different, the quality was in the same category. Upon re-surfacing they even audibly expelled air! And frankly, there really is nothing to compare to the look of those fiery red eyes with mere pin-prick pupils.

At the time, the event seemed a “once in a lifetime” thing and we were willing to accept it as so. Upon returning to the lake a week later, however, the sequence repeated itself and the only limiting factor turned out to be our available time on the water. We were the visitors to this lake and the loons, well, were residents operating within the limitless bounds of wildness.

Flight of the Sphinx

Filed under: Animals,BlogsMonroe — wykes @ 9:17 pm

Spurge Sphinx pupal skin photo IMG_0090_zps65so1n5y.jpg

Last summer I brought you some incredible views of a Spurge Sphinx caterpillar from Northern Michigan. Later in the month, after the leathery burrowed into the soil to complete its third stage of metamorphosis, I peeled back the moss to reveal the equally fascinating pupa at the end of the tunnel. The adult emerged last month, after a long frigid winter at the bottom of a dirt filled coffee cup, and it was worth the wait.

I was afraid of missing the moment and came close to doing so. One can never tell when the moth will emerge after months of non-activity. There was even the possibility that the winter would prove too much – especially given how low the thermometer plunged at times– and that the pupae would perish. Let’s just say that it was an incredible relief to finally peel off the lid last month and see the empty pupal skin (see above) and its former occupant clinging to the side.

I missed the actual emergent moment by a day or so and could see that the moth had been out for at least one night of activity within the container. Many of the scales were worn off the back of the thorax and the ends of the wings were slightly worn, but it was in pretty good shape otherwise. Spurge Sphinxes, like most of their clan, are subtle beauties to behold. The rosy flush evident on the body and undersides was especially magnificent on this individual.

Taking it outside for a better look in the low evening sun, it began to vibrate its wings in preparation for takeoff. Moths need to raise their body temperatures up to near human levels in order for the thorax muscles to work and they do so by shivering. This one began with a staccato flutter of the wings (see movie here) which evolved over the course of a few minutes into a blurry all-body tremor (see second movie here).

Just before takeoff, the thing was shaking so much that it was perpetually out of focus – or appeared so. With a final wipe of the eyes and a twist of the head it rose off my finger and flew off (see final departure here). Yes, it did seem to motion with the foreleg, as if giving a wave, but I won’t go there. I’m the one that eventually waved, saying “it’s been good knowing you.”

What Do the Skinka Do?

Filed under: Animals,BlogsMonroe — wykes @ 8:35 pm

Five-lined Skink Sunning photo IMG_0348_zpsqsefxcqk.jpg

The skinka – the five-lined skinka to be precise –do what it hasta do to stay alive and healthy. A big part of this survival strategy involves keeping the inside fires burning and because lizards like skinks don’t have inside fires they depend largely upon the generosity of the sun. For them life is all about generating warmth, keeping it, and turning it down when necessary.  An overly warm or dangerously cool skink is a lifeless skink. Cold-blooded creatures are not held hostage by solar power and ambient air temperatures, however. They can play the micro-habitats within a habitat like a fine-tuned instrument. A deeply shaded spot will allow for cooling, a lightly shaded location permits a slight elevation in body temperature, and a bright patch of open sun will, well, you get the idea. They move around quite a bit over the course of a day, an hour, and even a minute to exploit the mini spots within their macro domain.

The word to cover this life skill is behavioral thermoregulation, is only slightly shorter than the length of the creature itself. I promise not to use it again except in passing.

My Dollar Lake dock is part of the range of a cluster of Five-lined Skinks who use it from time to time for sunning. I never know when I’ll spot one and will go many months between sightings. Last week I nearly stepped on one. The individual, an adult male, was only slightly perturbed by my presence. Adult Skinks lose the five line blue-tailed look of youth as they mature and attain a bright reddish hue about their heads – looking as if they were victim of a head cold.

The skink did a surprising thing within my view. Rather than run off, it pressed its belly and chest flat against the dock wood and folded his feet back as if in a strait jacket. In this legless pose the thing absorbed heat from the warm surface. Within a moment or two it rose up and flitted across the dock and jumped into the shoreline weedery.  This being the first time I’ve actually observed a behavior other than fleeing I was fascinated by this deliberate little act of thermoregulation. It was a tiny peek into the skinkas daily do…ings.

Woodpecker Watering Hole

Filed under: Animals,BlogsMonroe — wykes @ 9:16 pm

Woodpeckers will come to earth, so to speak, for the purpose of getting liquid refreshment but many of them avoid this potentially dangerous trip by frequenting tree top watering holes. Certain shallow tree cavities regularly accumulate rainwater and serve nicely as natural reservoirs. One such drinking establishment exists on a Red Maple overhanging my shed at Dollar Lake.

Red-belly at the Tree Bar photo IMG_0175_zpso2dwlusv.jpg

I managed to catch a Red-bellied Woodpecker in the act one fine late June morning. It spent several minutes dipping into the reservoir and raising its beak to let the refreshment obey the laws of gravity and slide gently throat-ward. Based on the obvious look of satisfaction the bird’s time was well spent. It left with a red(dish) belly full.

Such tree water probably has a strong “woody” taste in the best of conditions but this might be a preferred essence for discriminating woodhammering fowl.

A Midge with Mites Upon’em

Filed under: Animals,BlogsMonroe — wykes @ 4:32 pm

Midge with Mites photo IMG_0198_zps5neiliim.jpg

A midge with mites upon ‘em

might be covered top to bottom.

Though small the midges are,

Their mites are tinier by far.

Let me start out by saying that Chironomid Midges are not Mosquitoes.  Similar looking to their blood-sucking dipteran cousins, they do not, and cannot, bite humans. I figure that knowing this will enable you to reserve your slapping energy this summer.   As larvae, midges live in the water and glean a living off microscopic plant matter and detritus. As adults they emerge and engage the world as flying beasts – seeking sap and each other.

Several of these critters landed around me one afternoon. All of them were males seeking refuge from the wind under the porch eaves. I was reading a book about making moonshine whiskey but I doubt that had anything to do with my sudden attraction.  Male Midges have hairy “plumose” antennae which make them easy to separate from the narrow-antennaed females. Heeding my own advice I did not try to shoo them away. Instead, I did the opposite and carefully observed them through the lens of my camera. When several revealed that they had passengers in the form of tiny red mites I was, as they say, “engaged.” Those ensy-weensy flies had ensy-weensier cargo attached to their legs.

Without getting into details, there are probably dozens of species of mite that infest midge flies alone. I found at least nine species over the course of my cursory review of the subject and all are members of a group known as Hydrachnidia. Like the midges, the mites are aquatic in the very first stages of life. They attach to the midge nymphs and transfer to the adult when it emerges. While attached they feed on the body fluids (aka blood) and eventually drop off into the water to resume an aquatic life. While their young are parasites (specifically ecto-parasites – which means they stay on the outside of the body), the adult mites are aquatic predators. Mites are related to spiders and possess eight legs when adult.

Given the amount of mites glomming onto the two midges I photographed it is amazing that their host could fly, yet all flew with ease. The mites were concentrated on the legs and thorax and left the wings unencumbered. There is no way I could identify the specific mite species involved here because even on an enlarged image they looked like fuzzy views of the planet …er, excuse me…the planetoid Pluto. Researchers, however, have done some work on this topic and discovered that some feed exclusively on the thorax while others concentrate on the long segmented abdomen.

Midge with Mites photo IMG_0181_zps8semsyz9.jpg

My small, along with their smaller, visitors would take flight after a few minutes and leave me to ponder several final thoughts. First, I assume that it is bad taste among midges to mention, or otherwise point out, the presence of mites on their fellow midges much in the same way as it is verboten to point out pimples or warts on humans. Secondly, it is imperative that these midge mites return to the water. It is their duty, therefore, to suck just enough blood out their host to live on but leave enough so that they can return to the lake. The idea is for the male midges to assemble with the females in huge midge clouds for the purpose of mating. I am guessing this is the moment chosen for the mites to drop off or forever regret their decision. There is much I do not know about midge mites, but for the moment this will have to do. Moonshine whiskey sounds a bit more fascinating for the time being.

Queen Among Snakes

Filed under: Animals,BlogsMonroe — wykes @ 9:14 pm

Queen Snake photo IMG_0135_zpssncjkewt.jpg

I was at the Huron River boat launch waiting for my group to show up and had time to kill (and no problem killing it because the rain clouds were still a half hour away). Looking over the edge of the board walk at the water’s edge I spied an interesting snake draped on the grape vines below.  It literally looked as if was carelessly tossed onto the greenery.

Small and dusky blue gray in color, the creature lacked the expected mottling or patterning of a Northern Water, Garter, or Fox Snake – the common local species of record. A creamy yellow side-stripe bordered by a chocolate stripe pegged it as a Queen Snake and a truly interesting find. I’ve only managed two sightings of this unique critter over the past 30 years or so.

Queen Snake photo IMG_0146_zpslukecwmd.jpg  Queen Snake photo IMG_0140_zps7qwvao5v.jpg

Queens are only found in southern and southwestern part of the state and are never common within their range. In fact, these water snakes are becoming a bit scarce because of their sensitivity to polluted or heavily silted waters. They specialize on crayfish as prey and seek freshly molted individuals as a way to prevent hard shells and pinching claws.

I am at a loss to completely describe the background meaning of the Queen Snake’s name and the scientific name is of little help. Dubbed Regina septemvittata, the whole thing can be translated as the “seven-striped Queen.”  Only young snakes exhibit the seven stripes of note. The adults darken in color and only display four real stripes. While King Snakes are snake eaters, and thus rule over all snakes, I can’t come up with a good generality about Queens other than they tell everyone to eat cake! In the long run, it really doesn’t matter.

The rain clouds traveled faster than expected and a heavy cloudburst eventually propelled the reptile back into the water after a few minutes. Fortunately, I got a good viewing of the Queen and was happy for the opportunity to share it with you.

There’s a Joke Here Somewhere

Filed under: Animals,BlogsMonroe — wykes @ 4:51 pm

A Bagel photo IMG_9545_zpsugajhajz.jpg

It’s one of my few memorable jokes, or as my wife puts it, one of my three jokes. Organized jokes aren’t my forte. There’s the one about the skeleton at the bar and the human cannonball and things get thin after that. I’m more of a “make up your joke to fit the situation” and “bad pun” type of guy. But, seeing this over-eager Ring-billed Gull holding a thin-sliced bagel the other day prompted one of my organized jokes to bubble to the surface (and one I’m sure I’ve told in the blog previously, but don’t stop me if you heard this one before).

You see, it’s long been a bugaboo of mine when folks call all gulls “seagulls”. There is no such thing as a “Seagull” unless you consider Jonathon Livingston a real bird. Nope, there are Herring Gulls, Ring-billed Gulls, Bonaparte’s Gulls and even Greater and Lesser Black Backed Gulls but no actual Seagulls. Some of them indeed live by the Sea and could be called sea gulls, but if one continues with that stream of logic then then a gull flying over a bay should be called a bagel (rim shot).

Thus, a gull with a bagel was too much to resist.

One Pic Post: Up Periscope

Filed under: Animals,BlogsMonroe — wykes @ 11:05 am

An Otter in Periscope Mode photo IMG_9149_zps4ohi8jdy.jpg

I’ve learned over the past few years to read the bubbles on Dollar Lake. Different patterns serve as clues to identify certain aquatic critters before they appear above the surface. For instance, a cluster of bubbles issuing from one spot indicates the feeding activity of a muskrat as he pulls up plants from the bottom. A line of bubbles advancing slowly across the surface is the mark of a turtle plowing through the underwater grassland. A procession of quickly advancing bubbles – coming up here and suddenly appearing six feet further on- is the signature of a hunting otter.

A quick line of bubbles suddenly appeared on the lake this past weekend to serve as notice that the otter was back. Actually I’m not sure if it is THE otter or if different individuals come and go (I otter know but I don’t). I do know that crayfish are typically the main menu item. I don’t know exactly what this critter was nabbing this time around but suspect that a painted turtle was part of the fare (based on the large yellow plastron-like item it was swimming with earlier). Its last dive brought up a mysterious cigar shaped item -looking almost like a small foot!

Upon spotting me on the dock the otter periscoped to get a better view. With its sleek short fur, tiny ears, large eyes, and long neck the Dollar Lake Otter looked very much like a seal. Unfortunately I never got a better look because it retreated to the privacy of the wild side of the lake’s wild side. This was about as good a look as one could ever expect so it definitely gets my seal of approval.
