Photo of the Week – October 27, 2017

I spent much of this week at our Niobrara Valley Preserve.  During most of that time, photography was difficult because of bright sunlight, no clouds, and strong winds, but the place was still beautiful.  Most of the colorful leaves had already fallen from the sumac, ash, oak, and cottonwood trees, and I only found a few asters that still had flowers.  Regardless, there was plenty of life to be seen.  I spotted a kangaroo rat in my headlights as I drove down the lane to the headquarters my first night.  Bald eagles were wheeling above the river, and I saw red-tailed hawks, American kestrels, and northern harriers hunting as well.  Flocks of other birds went here and there, either migrating through or just moving nomadically in search of food.  During a couple evening walks, the relative quiet was broken by high-flying squadrons of sandhill cranes passing overhead.

Late day light on ponderosa pine skeletons, burned in the 2012 wildfire.

One evening, I climbed up to the top of the ridge north of the river and photographed the landscape as the sun went down.  By the time I got back down to my truck, it was pretty dark, and I became very aware of how many shadowy places were available for creatures to hide.  I started musing that I still hadn’t seen a mountain lion at the Preserve, even though we know they’re here, and have had several documented recently.  Then I realized that it was less important to think about how many mountain lions I had seen and more important to think about how many lions had seen me!  I’m pretty sure that second number is higher than the first.

Many of the pines killed by the 2012 fire have lost their tops to the wind, but this one was still standing tall and intact.

While cloudless skies make daytime photography difficult, they do have their advantages at night, especially when the wind calms down enough for long exposures (the camera shutter was open about 25 seconds to capture this starry scene).  The light along the horizon is not from the setting sun, but from the closest town of any size (Valentine, Nebraska, population 2700) which was about 25 miles away.

Only a few trees still had their leaves this week, making them stand out in the river valley.

I will be up on the Niobrara again late next week, and I’m really looking forward to it.  Even in the dormant season, there’s always plenty to see.

As the growing season comes to an end and most wildflowers wind up their blooming period, insects that feed on nectar and pollen have to work a lot harder to find food.  The few remaining plants with active flowers suddenly become really popular.  In this part of Nebraska, those last remaining wildflowers include species like tall thistle (Cirsium altissimum), heath aster (Aster ericoides), and New England aster (Aster novae-angliae), among others.  The other day, I spotted a lone New England aster plant being mobbed by hungry insects.  Here are some photos…

 

Over the five minutes or more that I watched the horde of insects on this plant, I saw the same individual blossoms get worked over multiple times by multiple insects.  After all that activity, I can’t imagine any of those insects were really getting much of anything out of those flowers, but they were certainly trying…

Painted lady butterflies are still pretty abundant, but not nearly as abundant as they were a year ago.

How many insects can you find on the photo below?  I can find four painted lady butterflies, a skipper butterfly, three different bees, and a tree cricket.  Not pictured are a couple of grasshoppers and a few other bees that were just below the field of view.

I assume the remaining painted lady butterflies will migrate soon, but most of the other pollen and nectar-eating insects around here don’t have anywhere to go.  Some will simply die with the flowering season, but others will spend the winter in a state of dormancy and re-emerge in the spring.  I sometimes use the analogy of watering holes in Africa when talking about flowers and pollinators.  In this case, the analogy seems particularly apt as the last “watering holes” are drying up and the animals relying on them are highly concentrated.  I was surprised not to see any “crocodiles” (e.g., crab spiders) at this particular watering hole, taking advantage of an increasingly desperate prey base.

I appreciate living in a temperate zone where I can enjoy a nice variety of seasons through the year, but I’ll certainly miss seeing (and photographing) flowers and insects over the winter.  It’s hard to focus on indoor work these days, knowing that my opportunities to see those flowers and insects this season are dwindling fast…
