The Arrival of Winter - A Sign of the Season to Come?

Well, winter suddenly descended last week with a blast of strong wind that was followed a few days later by a thin blanket of snow.  This was enough of a shock to my system - I'm very thankful I don't live in south Buffalo, New York, right now!

While nothing too exciting has happened with this seasonal change, above and beyond earlier-than-usual cold weather with a couple inches of snow, it still seems like I ought to celebrate the arrival of winter with a brief post.  So here goes.

Since there was little transition between the relatively warm fall weather and a cold snap more typical of January than mid-November, quite a few trees and shrubs were caught with leaves in place.  Thankfully, we didn't get ice, so the leaves simply freeze-dried in place.  Some species, like cottonwood, have gone ahead and shed the remainder of their leaves.  Others, like the oaks, are still sporting a green coat.

This is the young Shumard oak that we planted shortly after we moved in.  I wonder how long the leaves will stay green this winter?

My aromatic asters were also still blooming when the cold hit.  Despite their late bloom cycle, this is the first year I've noticed any of their blooms getting caught by winter weather.  The purple is still obvious, 10 days after the cold originally hit.  How long will I have purple "blossoms" coloring the winter landscape?

After snapping a few pictures of the asters, I noted this grayish "growth" on the side of a basket sitting on the front porch.

Recognize it up close?  A praying mantis's egg case.  I'm actually rather surprised that I haven't found more of them, as I had many, many praying mantises in my gardens this year.  I feel rather lucky that all of the mantises I've seen have been the native Carolina mantis, rather than the interloper, the Chinese mantis.

In the back yard, I managed to catch a photo of a white-crowned sparrow hiding on the far side of a rose bush.  I was quite close, but evidently this little beauty felt safely hidden, because it made no move to flush while I stood there.





The most unusual sighting was the set of little tracks going across the driveway, between the redcedar hedge on the south side and the Rose of Sharon on the north side of the driveway.


With the obvious marks of the tail dragging, I'm quite sure it's a rodent of some sort.  Perhaps a hispid cotton rat.  I really don't know how to tell different rodent tracks apart, but I do know that I've got plenty of cotton rats around!

I didn't get out to take photos until 2 days after the snow fell, so I have no glorious shots of snow, quietly sifting out of the sky, or sitting heavily on the branches of the trees, but there was still enough snow around to document the start of winter.

Each year is so unique - I wonder what THIS winter will bring?  Is this early snow the sign of much more to come?  Or is this the only snow we'll get all season?  There's no way to know so, as always, we'll take the new season, day by day, week by week, month by month.  Suspense - natural style.

Diversity!

Greg gave me a gift for Christmas last year - Access (the software program, which unfortunately doesn't automatically come with the home version of Office) so that I could begin to keep a coherent database of all the plants and animals that I've found on our 10 acres.

I have been slowly working on this project in the intervening months, and I'm far from done.  For the most part, I've been utilizing the photos I've taken over the years to remind me of what I've found and where I've found it.


For example, I saw this flower beetle (Batyle suturalis) on Black-Eyed Susan (Rudbeckia hirta) in the Back Five early in July this year; both species are now in my database.



The wonderful folks at BugGuide.net are probably quite sick of me, as I've been submitting quite a few photos for their help with identification - which has been wonderful and greatly appreciated.  I can usually get an unknown insect down to order and often to family, using my experience and (if necessary) Borror and DeLong's Introduction to the Study of Insects for its excellent keys .  Then I try, utilizing BugGuide's online guides, to get the insect down to genus and species, but without actual keys specifying what I'm looking for, it can be hard.  It's at this point that I will submit an image for help.


Other species are often easier.  For example, I've been birding for years, so I have a reasonable familiarity with bird species and I can trust my identifications and the species lists I've been keeping since we moved in.  (Besides, it is much easier to figure out which of 450+ possible species a bird is compared to figuring out which of thousands of possible species an insect is.)  Below, for example, is a red-winged blackbird watching a little blue heron, who hung out in our lagoon for several days in 2009.

There are a variety of books and online resources I go to for plant identifications:  Michael Haddock's book and website on Wildflowers and Grassses of Kansas.  Janet Bare's book, Wildflowers and Weeds of Kansas.  Stephen's book, Trees, Shrubs and Woody Vines in Kansas.  And many, many more.

I've recently purchased Bradley's book, Common Spiders of North America, to improve my ability to identify the spiders that I'm seeing.  BugGuide is also useful with spiders, and I have a few other guidebooks (although most are much less comprehensive than Bradley's).  Below is a male jumping spider (Phidippus clarus) which I photographed last summer hanging out on giant ragweed (Ambrosia trifida).

There are, obviously, many more references that I use to compile my species lists, but that isn't the point of this post.  Right now, according to my Access database, I have 201 plant species that I've found (or planted) on our 10 acres, 157 species of insects, 3 species of amphibians, 8 species of mammals, 1 species of snake, and 5 species of turtles.  (I have found quite a few more species of amphibians, mammals, snakes and turtles than that, but I haven't put them into my Access database yet.)  My yard list has 121 bird species so far.  That includes birds seen ON our property, as well as FROM our property (i.e. flying overhead during migration or seen from our property but physically on our neighbors' land).  I haven't started a list of spider species yet, but in looking in my photo organizer, I easily have at least a dozen different species.  Then there are the assorted invertebrates not covered by "insect" and "spider" catergories, species like prairie crayfish, roly-polies, and daddy longlegs.


Here is a boreal chorus frog (Pseudacris maculata) in the buffalo grass (Bouteloua dactyloides) of our front lawn last August.



So, in the 7 1/2 years we've lived here, I have documented (so far) 310 animal species and 201 plant species sharing our 10 acres with us.


Why am I posting about this right now?  Because in yesterday's Wichita Eagle, there was an article about Chisholm Creek Park in northeast Wichita.  The article was actually about algae in the lake there, but there was a brief aside saying that "[t]he park is home to 163 species of plants and 214 species of animals...."  Chisholm Creek Park is large - 282 acres, according to the website of the Great Plains Nature Center, which is located there.

I have documented about 25% more species of plant species and almost 50% more species of animals on our 10 acres than have been documented in the 282 acres of Chisholm Creek Park in the same county.

Does this mean that there really ARE that many more species on our little 10 acres than in Chisholm Creek Park?  No.  Absolutely not.  The species summary list on the Great Plains Nature Center site above does not give any number of species at all for invertebrates or grasses, for example, and their numbers for birds, mammals, reptiles and amphibians are all greater than the number I've observed on our property.  Chisholm Creek Park also has fish species, while we have no year-round water habitat except our lagoon.

I've just been more meticulous about recording (and identifying) the variety of species I've found here, particularly the species of insects and other invertebrates, than the folks in charge of that park have had the time or the inclination to do.  Still, it was definitely a psychological boost to realize just how diverse a piece of property we actually have!

Do you keep any sort of species list of what you've identified on your property?   If so, what sorts of insights or discoveries has that process given you?

Rock-A-Bye...Raccoon?

One advantage to owning two large German shepherds when you live out in the country is that they HAVE to have their morning walkabout.  In the last several weeks, we've had several "cold" snaps, accompanied by snow or freezing rain or ice pellets.  These are definitely NOT considered sufficient reason to stay inside by The Boys.  It doesn't matter how ugly the weather is, they need a bit of romp time...and so I "suit up" to suit the weather and out we go.

Although it's hard to convince myself of the positive side of these walks when I'm donning waterproof shoes and wind-and-rain-resistant coat, facing cold winds that will cut through everything I have on, I do get to see some things that I'd probably miss otherwise. 

Sometimes I even have my camera along to capture the experience.  Here, for example, is one such time....

Look closely at this photo.  See anything much besides a bunch of snags and last year's dead plant stems, waiting to decompose?  I took this photo a week ago, on the day we woke up to snow.  This was taken about mid morning, after most of the snow had melted but while the temperatures were still quite chilly.

Look more closely at the center of the photo, right at the top of the broken black willow, where the top part of the trunk heads downwards at 90%.  (Yes, it's ugly.  No, I shouldn't have had someone out to "take care of it."  And this is why!)

See that bundle of gray fur?  I think it's a raccoon, perhaps the one that I photographed a couple weeks ago, climbing up a nearby black willow that was similarly "past its prime."  It could, however, be an opossum.  Anyone who is better than I at identifying fur is welcome to chime in with a positive identification!

Whichever it is, this is evidently a favorite hangout, especially (weirdly) in cold, wet, spring weather.  I saw it again this morning, similarly curled up, with enough rain falling that I'd taken neither my camera nor my binoculars along on our walkabout.  There it lay, seemingly snug as a bug in a rug.

Raccoons denning in hollow trees.  Raccoons napping in snags.  Woodpeckers nesting in holes, drilled into standing dead trees.  Insects overwintering in standing dead plant stems or snuggled deep in leaf litter.  We humans may see dead plants as ugly trash, messing up our landscape, but wild amimals view dead plants as shelter - safe, comfortable places to weather storms and cold and rain.  Secure places to raise the next generation. 

So, before you automatically cut down that dead tree at the back of your property, stop a minute and really analyze the situation.  Is it likely to fall on a building or a person passing by?  By all means, cut it down, and the sooner, the better!  But if that dead tree is not likely to cause any harm, then consider leaving it as a sort of wildlife hotel.  You never know what may decide to take up residence there!

Another Discovery Through Walking

I can't believe how much I get to see just because the boys encourage me to get outside and walk every day.  Truly, I think I'd miss 90% of what's happening around here, if it wasn't for their daily insistence on getting out for a constitutional.

This morning gave me another perfect example.

What do you see in this photo?  Anything besides a messy tangle of trees and vines?

Look a little closer!

As I followed the path beside the draw this morning, I noticed a bit of movement further in, among some vines by the ground.  At first, I thought I was seeing a big feral cat...but a moment's observation showed me what it really was!

Unhurriedly, but without stopping, the raccoon climbed the vines, seeming to pause only briefly to check me out.

He (she?) clambered onto the branch...

walked along it without changing pace...

climbed onto the trunk...

and disappeared!  One moment it was there and the next moment it was gone.  I watched for a couple minutes more, but saw no further movement.

So I continued on, along the west side of the draw, looking more closely at the tree (especially the area where the raccoon disappeared) when I came closer.  Nothing obvious there....

Then I went around to the east side of the draw...and this is what I saw through the brush.

Walking a little further on, I was able to get an even clearer view.

That, however, was the best I could do without getting on to the muddy, overgrown floor of the draw itself.

I've occasionally seen tracks I thought were raccoon.  Now I've seen who made them!

Animal Enigmas: Spring on the Prairie

Spring on the prairie can be quite enigmatic.  Heck, life on the prairie, at any time, can be quite enigmatic!

As I walked around this morning, I found several freshly excavated holes.  They were about 3" wide and easily as deep, maybe a bit deeper.  This one was quite near the back yard....

...but these were part of a cluster of about a dozen, similarly sized, in the middle of the Back 5. 

In my experience, these holes aren't big enough to be an armadillo's work, let alone a coyote's.  Given that the cluster of holes was far from any tree, I tend to discount a fox squirrel as the digger, which was the first possibility that popped into my mind.   On the other hand, the holes seem too big to have been made by a mouse, a vole or a cotton rat.  Cottontails don't dig holes of this nature, that I'm aware of.  Perhaps a skunk?  Does anyone have any guesses...or, better yet, any knowledge of what might have caused this size of hole, at this time of year?

Detective work of this sort underpins quite a few of my prairie "sightings".  For example, I know we have a fairly active coyote presence, but I rarely see them. Unfortunately, when I do see them, I'm so thunderstruck that I don't even think to throw my camera up and take a quick shot - if, indeed, I have my camera with me.  So far none of the coyotes I've seen have sat around patiently and waited for me to take their picture.

We do hear the coyotes, at night, fairly regularly.  

Two winters ago, we noticed several large holes that had been dug in the Back 5 and I eventually figured out that they were made by coyotes, digging up vole colonies and eating yellow-jacket combs (and probably some voles as well).  By the way, the blue cell phone in the hole is there for scale.

That same winter we had the mystery deer skull appear and move around a bit, eventually parking itself for almost a year beside a compass plant, before magically disappearing one night.  The dogs were always VERY interested in the scents they found around that skull and made a beeline for it as soon as they got close.

Yesterday, I found signs of coyotes again.  This time I noticed tracks, sized appropriately for coyotes, on a couple of leftover snow drifts.  Note the (significantly larger) tracks that Becker made next to the coyote tracks.

Of course, it's also pretty common to find coyote scat, a.k.a. coyote poop, along the trail too.  This is distinguished from dog poop by being smaller and from cat poop by being larger.  It also tends to be full of hair and bones.  There wasn't a great deal of scat to be seen this winter, but in the last few weeks I've been noticing more and more.  Here is one of the coyote piles, showing the hair that commonly makes up such a large portion of their volume.

A couple years ago I even found some coyote scat with cat claws in it, so I knew that one of the many barn cats in the area had been added to the food chain.  Scientists make studies of the bones and hair in scat to determine what the animals they study are actually consuming.

Another common animal trace that I see is a trail.  Some trails are larger and show up in the grass, like this one I photographed leading towards my neighbor's plum thickets.  I believe this trail was made by rabbits....

However, some trails are fairly faint, showing up best after a burn.  These, for example, are prairie vole trails that I photographed after our last burn.  Normally I don't notice vole trails at all, except occasionally when a particularly well trafficked one crosses over one of the mowed paths in summer.

The last trail I'll show here was invisible when it was made - under snow - but exposed when that treacherous white stuff melted.  It seems smaller than a vole trail, so I'm guessing that it's a mouse trail of some sort, but I'll have to do a lot more research to figure out what species.  Unlike the vole trails, shown above, this one was deeply and precisely incised into the soil.  Interestingly, it disappeared from view soon after being exposed and now, 3 weeks later, there is absolutely no trace of it.

Greg got me a trail camera for Christmas, which I've been playing with in and around the bird feeders.  Now that the soil is softer, it's time to sink a couple posts around the property and find out for sure what animals are busily creating puzzles for me.

In the long run, sometimes the most interesting observations and findings come simply from being alert to changes, then asking myself what could have caused an effect like that.  It's far from an exact science - but it certainly keeps the old brain cells busy!

Possum Pellets

In the comment section of an earlier post, I mentioned the "possum pellets" that I frequently find in the birdfeeders, letting me know that an opossum has been enjoying the largesse I put out for the birds.  I finally remembered to get a photo....


The main photo is really too busy to be able to see the pellets clearly (they seem much less "camouflaged" in real life), so I zoomed in to let you see the pellets up close.  The closeup is a little fuzzy, but gives a better feel of what you'll see in the feeder.

It Certainly Didn't Play Possum!

I had a usual visitor at an unusual time of day today:  an opossum decided that the birdseed in one of my feeders was much too delicious to leave alone just because the sun was coming up.
I've had opossums at my feeders off and on over the years and I knew that I was hosting at least one this fall, since I would find the pellets in the feeder in the morning.  (Also, when we were having skunks visit regularly in the evening, we would often see them while we were doing a skunk-check with a flashlight before letting the dogs out.)


This morning, when I somewhat blearily surveyed the backyard feeders, I suddenly woke up to the fact that the tree trunk hadn't, in fact, grown a burl overnight - there was a fairly small opossum on it, perched a few feet above the hanging platform feeder.  It stayed there most of the morning, carefully watching my movements in the house.  When I let the cat out, she noticed the opossum and climbed the tree (to investigate more closely?) but stayed at least 3' away at all times.  The opossum simply kept quietly watching her and me.


After I went upstairs for a while, the opossum decided the coast was clear and descended to the feeder to continue chowing down.  When I let the shepherds out for their walk late this morning, Becker and Blue looked at it for a while but made no effort to catch it, although it was probably well within their reach on the feeder.  In fact, the cheeky little thing didn't really get upset at all, even when I decided this was an opportunity to get a closeup photo or two.  Throughout all the staring and shutter snapping, it stayed firmly on the feeder, watching carefully and occasionally pulling its lips back a bit.  By the time I got back from a trip to town later this afternoon, though, it had moved on. 


I learned something new tonight:  a "possum" is actually an animal that lives in Australia or New Zealand.  Our North American marsupials are correctly called "opossums."   There are apparently 103 species of opossums in the Western Hemisphere!  The species we have here in Kansas is the Virginia opossum, Didelphis virginiana.  It was originally confined to the East Coast, but was spread to the West Coast during the Depression, perhaps as a source of food.

Opossums have never concerned me too much.  They are fairly resistant to rabies and thus are very uncommon carriers of it, perhaps because their body temperatures run low for mammals (94-97 degrees Fahrenheit).   They are not really aggressive, hissing loudly when threatened but not likely to attack.  And, of course, they are well known for their habit of falling over, as if dead, when really threatened.

As I did research this evening, I learned that opossums are occasionally called "Nature's Little Sanitation Engineers" for their eating habits:  primarily animal material such as snails, slugs, insects, spiders, rats, mice, even snakes.  They will also eat fruit (especially fruit drop on the ground), berries, nuts, and vegetables.  And they eat carrion.  As is typical of such omnivorous animals, they are easily attracted to yards with such attractions as pet food left out overnight, garbage cans without tight lids, and...full birdfeeders.

On the plus side, one source I read even suggested that opossums may help reduce the spread of Lyme disease, since they "kill off" (eat?) almost all the ticks that feed on them.
 



Overall, I consider opossums to be benign yard guests - no more of a problem than squirrels, with a similar likelihood of getting into attics or sheds or garages if I'm lazy enough or silly enough to leave openings for them to do so.  And if I really cared about keeping them out of the bird seed, I would simply pole mount all of my platform feeders.


In fact, having read the list of their preferred foods, I strongly suspect that opossums provide me with a reasonable amount of pest control for the relatively minor cost of a bit of bird seed.

So, until and unless one really causes me a problem, I'm going to relax and enjoy this neighbor with whom I'm sharing the yard and gardens.  Diversity, after all, is the spice of life!

Discoveries after the Burn

It's been a good day - I've discovered a few things and, most importantly, learned something new.

I've been walking the burned area almost every day since we burned it, just open to whatever I might see. Here's what it looked like this morning....


You can see how quickly the grasses are coming up. It's only been 8 days since we burned and there was absolutely no green visible after the burn. You can also see last summer's path meandering through the burned area.

I mentioned a couple days ago that within a few days I was also able to see our paths from 2 summers ago, as well as the network of prairie vole trails. Here's a photo, taken while standing in the fire break, of last year's path (going off to the left from the firebreak) intercepted by the prior summer's path coming in from the right. If you look closely, you can see a fair number of prairie vole trails as well.


In the next photo, you can see a network of prairie vole trails and a mound that's greener than the surrounding area. That mound is the prairie vole colony itself. I believe that the mound is greener than the surrounding area because of extra nutrients brought up from the subsoil as the voles excavate their tunnels. Prairie vole "fertilization" in the area may play a role as well. Beyond the mound is another trace of our path from 2 summers ago.


As I walked our path a couple days ago, I found this prickly pear cactus immediately adjacent to the mowed area...yet I hadn't had a clue it was there until after the burn! That doesn't say good things about my observation skills, I guess, especially since I knew there was a prickly pear somewhere in the area - I'd seen it after our original burn.




Most interestingly, near two of the coyote digs I found wasp nest combs that can only be from yellowjacket colonies. The photo to the left shows a close-up of one of the charred combs; the one below shows the same comb in the bottom left corner and the colony it presumably was dug out of in the top right corner. So now I'm questioning whether the coyotes were digging for voles...or whether they were digging for yellowjacket nests. It's an interesting mystery to ponder (and do a bit of internet research on).



As I said, it's been an interesting and successful day already!

After the Burn is Over, After the Flames are Gone....

(You can sing the title to the tune of "After the Dance Is Over, After the Music's Done....")

Sunday, the day after we did the burn in the back 5 acres, I took The Boys for a walk and looked it over a little more closely. It's always fun to see what's revealed after a fire....


For the past week or so, there's been an elusive deer skull taunting the dogs as we walked out back. I first saw it in the neighbor's field when Becker and Blue just HAD to go over there to inspect it. There was a companion leg associated with it, which was almost more fascinating to the dogs than the skull. Perhaps that because the skull was covered with soil and looked like it had been partially buried. Both looked pretty "ripe", like they'd been aged quite thoroughly.

The next day when we walked, the skull and leg were magically in OUR field, about 50' from where they'd been lying the day before. There they stayed for 2 more days, then magically they moved again. This time the skull went south and the leg went east, instead of staying together. My dogs faithfully found them each time they moved. (I'm attributing this "magic movement" to coyotes, of course.) I don't mind if my local coyotes want to munch on decayed deer flesh, but I'm really not too keen on my dogs doing so; therefore, this daily deer skull hunt had really begun to get on my nerves.

After the burn, the deer skull stood out boldly. The leg was much less visible. I'm curious to see what happens to them now that they've been "purified" by fire, so I'm continuing to just let them be.


Another sight that I always look forward to seeing after a fire are the prairie vole colonies and their associated runways.


I don't know why these fascinate me so much - maybe because it reminds me of playing with Matchbox cars during childhood! The little roads run from vole town to vole town and I can just imagine the self important little beasts scurrying back and forth, visiting their neighbors, gossiping about the good vegetation finds they've made recently.

This winter I've noticed fairly large holes turning up occasionally in the back 5. A couple have been as big as 18" X 12" and up to 12" deep.


At first I thought that some animal must be beginning to dig itself a burrow, but they never got deepened after the first time I saw them. Finally I decided it was coyotes (again), digging out the prairie vole colonies for a late night snack.

Boy, do those scars show up boldly against the burn. (The cell phone in the hole is to give you a sense of scale.)


Greg wants to fill in the coyote digs because he (correctly) notes that they will be real ankle-turners otherwise. While I know he's right, there's the curious part of me that wants to watch them and see how they change over the upcoming months and years. What's going to grow on the mounds of soil thrown up? Will the holes fill back in by themselves? Will they become used by some other animal in some other way? (Maybe I'll leave just one or two...and flag them, so we don't injure ourselves....)

Do I get upset about all of these disruptions to my slowly thickening grasses and wildflowers? Heck, no. The prairie vole colonies bring water and air down into the soil...and probably a fair amount of vegetation and fertilizer too. Other animals, from insects to other mammals to snakes, will utilize the vole tunnels for shelter. The coyote digs provide a small area of open soil for seeds to colonize, where new plants can gain a foothold. It's all part of the natural prairie cycle, and I love seeing it play itself out in my big back yard.
