Nature Photo Challenge – Wild Animals

While I edit photos for my next “regular” blog, I was inspired by Denzil’s 28th Nature Photo Challenge to post a few photos of wild animals I’ve encountered. While I could have chosen to show some of the more exotic ones (e.g., rhinos, elephants, lions, etc.), I thought I’d introduce you to some species that live in my general area.

Among the insects that I enjoy watching are the snowberry clearwing moths (Hemaris diffinis). The first time I saw a clearwing moth at some distance, I wondered if there was a tiny hummingbird with which I was totally unfamiliar. When I got closer, I realized it was no hummer but some amazing kind of flying insect. I still find them fascinating creatures.

The saddleback moth caterpillar (Acharia stimulea) is another favorite from the insect world. Fortunately, I found out that they have a painful sting before I ever touched one. This past week, I was lucky to see one twice. The first time was when John, an odonate expert of my acquaintance, called me over to see one he had found. He had unfortunately been stung but said the pain was tolerable: I hope he didn’t suffer for long. Several days later, I spotted another saddleback while on another nature walk.

 The bright golden color of a common sawfly caught my eye after having seen the first saddleback. It was quite a striking fly with its black and white “decorative” highlights.

Shortly afterwards, my day was made when I spotted one of my favorite spiders, an adorable jumping spider that had caught itself a sizeable meal.

A couple days ago I startled an Eastern rat snake (Pantherophis alleghaniensis) as I passed by it on a path. I hadn’t realized it was there until the herp reared up and quickly crossed the path in front of me. I think we were both startled and I didn’t manage to get a photo. Today I did a U-turn to hop out of my car to carry an Eastern box turtle  (Terrapene carolina Carolina) to safety as it began crossing a busy road. One woman stopped to thank me, while another driver gave me a somewhat irritated look. The turtle above was not the rescue but had similar colors to the turtle today.

My pond is quite alive with lots of tadpoles and small frogs. This green frog (Lithobates clamitans) is one of the larger aquatic yard denizens.

I haven’t seen a wide variety of mammals lately except for the ubiquitous Eastern chipmunks, gray squirrels, Eastern cottontail rabbits and Eastern white-tailed deer in my yard. It’s always a treat for me to see some of the aquatic ones when out on walks, such as the river otters (Lontra canadensis) and the North American beaver (Castor canadensis).

I’ve seen the hispid cotton rats (Sigmodon hispidus) in three different North Carolina nature reserves. To my surprise, this year I also spotted one in my backyard, but I only saw it once. They are known to scurry away quickly when spotted.

And then there are the birds — they are by far the order of animals that I see most often and most easily. They are also delightful because of their great variety. Just recently, I saw a rare avian visitor to my yard, the black-and-white warbler (Mniotilta varia). I usually see them in nature reserves.

In contrast, the lovely little chipping sparrows (Spizella passerina) are birds that I often see in my yard and at my feeders. This pair was resting in a tree top near a former dairy farm, which is now being turned into a vast vineyard. Much of the birds’ habitat has been removed during this changeover to my great disappointment.

One bird that still remains in that area is the solitary sandpiper (Tringa solitaria), which is easily recognizable by its habit of bobbing its rear end as it walks along shores looking for food.

The sandpiper is not the only shorebird currently drawing birders in our area. Many varied species have been turning up at local lakes, giving birders the opportunity to see “lifers” (birds seen in person for the first time). The limpkin (Aramus guarauna) is one such bird for me — it was a treat to see it looking for clams and molluscs at a local lake.

Next blog: making acquaintance with a bird I’d like to imitate!

 

 

Growing up barred – Part 1: becoming independent

From the ages of about 8-19 years, I lived in a house that had a nice backyard and was not too far from some neighborhood woods with a creek. As a child, I read under backyard trees, planted a flower garden and played in the woods with friends. While I became familiar with squirrels, robins, frogs and some bugs and loved being outdoors, I didn’t spend lots of time looking for wildlife. And I never saw an owl in the wild.

Now decades later, I’ve had the good fortune to learn a good deal about various members of the wildlife community while spending time finding and watching them. And in the past couple years, I’ve been privileged to see owls up close in the wild; for example, the owl below was perched next to a pathway at dusk when I walked by a few days ago.

This past summer was unique for me, however, because I was able to observe a pair of juvenile barred owls (Strix varia) at the Mason Farm Biological Reserve as they set off on their life’s journey outside the nest. I’d like to share a bit of what I saw with you in a three-part blog. This one is about them finding their independence. The next two will focus on their grooming and interactions.

Barred owl pairs usually bond for life; if one mate dies, the survivor will seek another partner soon after. They tend 2-4 eggs, which hatch after 4 weeks’ brooding and the young leave the nest after four or five weeks. They remain dependent on their parents for food for some time after that even though they may be almost as large as the adults at 16-25 inches in length (40–63 cm); their wing span can stretch up to 3-4 feet (38-49 in, 96–125 cm).

When I first spotted the young owls in June, they could already fly. Nevertheless, they did need to find their balance occasionally as they perched and moved along branches and snags.

 

The owlets were making a keening noise the first time I saw them. At first, I didn’t recognize it, and I thought perhaps some small mammal was in distress.

Eventually, the plaintive call helped me locate them above me in a tree. This particular call apparently is used by the babies to call to their parents. I figured mom or dad was close by as the owlets kept looking upwards and eventually the parents did fly in with a meal – crayfish as far as I could tell.

 

On several occasions over the next 6 weeks or so, I would hear the owlets making that keening call and staring upwards. I figured the parents were nearby, but they were obviously just keeping an eye on their offspring and not feeding them (at least not when I was there).

It was time for the young ones to learn how to get their own meals.  Although barred owls usually hunt at dawn and dusk, the young owls were busy looking for food during the day. The mammals they eat include voles, mice, shrews, squirrels, rats, rabbits, bats, moles, opossums, mink, and weasels. Birds are also a food source and their prey may include woodpeckers, grouse, quails, jays, icterids, doves, pigeons, cardinals, cedar waxwings and grackles. They also eat amphibians, reptiles and insects (e.g., snakes, slugs, lizards, frogs and toads, salamanders, crayfish, turtles, scorpions, beetles, crickets, grasshoppers) and it was the latter group of prey animals that I saw the owlets hunting. Here for example, it appears one young owl had caught a crayfish.

One day, one of the pair was grasping a twig in its beak; I’m not sure what it was doing but it seemed to have some purpose. Perhaps it was testing how strong its beak was.

  

That a strong beak can be an asset became apparent on another occasion. One of the juvenile owls suddenly flew from one tree on the other side of a water ditch to one above my head. There was much rustling of branches and leaves and when I got into a spot where I could see the bird, it became obvious s/he had caught the largest stag beetle I had ever seen at Mason Farm Biological Reserve. It appears that the giant stag beetle (Lucanus elaphus) drinks tree sap, which must have been what it was doing when the owlet got hold of it. The problem for the owl was how to eat the beetle when those large pincers were in the way.

     

The owl would try to grab hold of a pincer but lose its grip; s/he would turn the beetle around but was having a very difficult time getting those defensive appendages off. This went on for quite a long time, which made me feel a bit sorry for the beetle.

 

Finally, the owl had success and was able to settle in for a crunchy meal.

 

They expel the indigestible parts of their prey in owl pellets that they cough up regularly. Here you see the contents of one a friend found under a favorite perching branch at the reserve.

Another day I saw one owlet suddenly fixate on the water ditch.It turned out that quite a large rat snake (Elaphe obsolete; Pantherophis alleghaniensis) was swimming by. The owl watched it carefully as it climbed out of the ditch and eventually crossed the adjacent walking path, never making a move to tackle the reptile. I had remarked on this encounter to the reserve’s land manager, who said it was probably a smart move on the owlet’s part, since the snake was large enough that it could have wrapped around the owl’s head and choked it.

The young owls seemed to have learned a lot about life as a predator as they grew older. It was fascinating watching them explore their world.

Next up: how the owlets cared for themselves.
