Ohio-Erie Canal

 

As always, click the image to enlarge

The long-abandoned Ohio-Erie Canal, in Cuyahoga Valley National Park, on a misty morning. Shauna and I had a great time visiting various spots in Ohio's only national park. This was a place called Beaver Marsh, and not only did we see that namesake animal, but lots of other interesting subjects. Summit County, Ohio, November 2, 2024.

PHOTO NOTE: This was very early in the morning, a bit prior to dawn. Mist was rising from the water in places, and the overall effect was dark and ethereal. We were there primarily for birds, and all I had was my 800mm telephoto on a tripod and a 16-35mm wide-angle and 100mm macro lens in my backpack. The 16-35, even at 35mm, was too wide to show this scene in the way that I wanted. The 800, which I sometimes do use for tight landscapes, was WAY too overkill in this situation. So, I popped on the 100mm macro lens (my body is a Canon R5, and all lenses are Canon). The macro lens can be surprisingly good for fairly tight landscape work, although I often forget to employ it for such purposes. Anyway, I wanted to exclude the rather drab white sky not far above the top of this image (which is completely uncropped), and the ghostly white trunk of the sycamore on the left drove my decision as to where to frame the left side of the composition. I liked the gnarly stump jutting from the water towards the bottom left so that decided where the bottom of the composition would go. The rest fell into place.

But a note about the macro lens, and higher ISO levels. I made this shot at f/16, 1/30 second, and a very high ISO 6400, handheld. I have found that - and sometimes forget - that the combination of the macro lens' "compression" and a relatively high ISO can create a very "painterly" effect to a treed landscape. There was absolutely no wind, and while there may have been a bit of camera shake, the latter was probably minor as the lens has killer image stabilization and I am pretty steady. Yet the leaves, especially, blur like a Monet watercolor - an effect I very much like in some landscapes. I cannot get that effect from my primary go-to landscape lenses, the 16-35mm and 70-200mm.

Had I had the 70-200 with me, I might have unthinkingly grabbed that, probably using about the same 100mm focal range as my macro, but would have put it on the tripod, set the ISO to 100 or 200 at f/13 or f/16, and made the shot. The shutter exposure would have been REALLY long (far too long to handhold) but who cares when it's on a tripod. But I would have ended up with an image that would be crisp throughout, and largely void of the soft blurred foliage of this shot.

Nature: Show-off herons shine in national park

A juvenile least bittern in the Cuyahoga Valley National Park

Cuyahoga Valley National Park’s 51 square miles preserves a treasure trove of biological diversity. Ohio’s only national park, it occupies the state’s most populous region and is bookended by Akron and Cleveland.

Although waterfalls, forests, rock formations, streams and other scenic items of interest lure visitors, it was one of the world’s smallest herons that drew me to the park a few weeks back.

For most of the summer, an uncharacteristically conspicuous pair of least bitterns put on a show along a boardwalk that bisects a lush marsh. As an Ohio breeding bird, this one is especially noteworthy. The least bittern is listed as threatened by the Ohio Division of Wildlife, and nesting locales are few and far between.

The least bittern is a true elfin in a family of typically robust birds. One of these diminutive waders is about the size and weight of a blue jay. For comparison, its much-better-known relative, the great blue heron, has a wingspan over four times longer than the bittern’s 17-inch set of flappers. The larger heron is nearly four times as long and weighs 30 times more than the bittern’s paltry 80 grams.

Size doesn’t dictate beauty, though, and the least bittern is exquisite. The bird’s feathers are a palette of rich chestnut, tan and cream. Greenish-yellow skin forms goggles around the eyes, and a stiletto-like bill fronts the face. Perhaps most amazing are the little bird’s big feet. They are disproportionately huge, the greatly elongated toes useful in tightly clutching the stalks of aquatic plants.

One reason the Cuyahoga Valley birds caused such a stir was the ease of seeing them. I’ve seen a fair number of least bitterns over the years, but I’ve heard far more. They frequent the densest stands of cattails and other wetland plants, and are often impossible to see. Only the curious cuckoo-like murmurings of the herons give them away.

My experience was typical of most visiting birders. Shortly after my early-morning arrival, one of the bitterns was spotted lurking at the edge of some cattails. Before long, another bird joined it. For the rest of the morning, great views were freely had.

Better yet, the extroverts were two juveniles — especially good news, as nesting was obviously successful. The adult birds called regularly from the cattails, but they did not show themselves during my visit.

It was a rare experience to observe the bitterns clambering about vertical cattail stems, stabbing at small fish and frogs with their daggerlike bills. At one point, a bird popped out in the open on some spatterdock lilies, enabling me to take the accompanying photo.

We have not been good stewards of wetlands, and least bitterns and many other species have suffered accordingly. These tiny herons were once common in Ohio wetlands, but they have declined tremendously. For instance, famed ornithologist Milton Trautman recorded nearly 100 pairs nesting most years around Buckeye Lake in the 1920s and ’30s. Today, there are none.

It is fortunate that we’ve set aside natural areas such as Cuyahoga Valley National Park to protect some of our biodiversity.

FURTHER AFIELD
