Picture Ohio! – Bald Eagles in Cuyahoga Valley National Park

Last week, on November 8, I was driving north around 11:00 am on Akron-Peninsula Road in the Cuyahoga Valley National Park. Just north of Ira Road, I  noticed a pair of Bald Eagles perched high in a maple tree on the west side of the Cuyahoga River. I pulled off the road, grabbed my Nikon D7000 camera and Sigma 50-500mm lens, and walked back down the road to try to get some photographs. One bird, a sub-adult, took off immediately, but the other, a handsome adult, stayed perched for about 30 seconds before taking flight. I was handholding the camera and lens, since there was no time to set up a tripod. Just one frame of the perched bird was sharp, shown above, plus one fairly sharp photo of the bird just after it took off.

According to an article on the Cuyahoga Valley website, Bald Eagles were almost extirpated in Ohio by 1975, with only four remaining breeding pairs. Since then, they have been increasing steadily, and today there are more than 200 breeding pairs in the Buckeye State, with the largest concentration in the Erie Marshes in northwest Ohio. Locally, a pair of Bald Eagles has been seen regularly in the Valley, and they have nested successfully and raised young. Bald Eagles often take over an existing Great Blue Heron’s nest, and the old heronry in the Pinery Narrows area of the Cuyahoga Valley has been the favored nesting place for the resident pair of Bald Eagles.

The abundant wetlands and expanding fish population along the Cuyahoga River bode well for Bald Eagles, and park naturalists expect the population of resident Bald Eagles to grow.

Picture Ohio! – Sandhill Cranes

A few days ago I was driving south from Burton, in Geauga County, after spending a few hours in search of dragonflies along the Grand River. I hadn’t taken a single photograph, and was about to write off the trip when I noticed a family of sandhill cranes feeding close to the road in a farm field. I drove a bit further, pulled over, and reached for my 70-300mm Nikkor lens, which was the longest lens I had with me. Then I turned around and slowly drove back along the road. By this time the three cranes had moved off into the center of the field, but I was able to get a few quick photographs from the driver’s seat of my 4Runner before the cranes disappeared over the field’s horizon.

The sandhill crane (grus canadensis tabida), is an endangered species in Ohio. These large birds, which can stand four feet tall with a wingspan of five or six feet, are on the increase in the Buckeye State. Studies by the Ohio Division of Wildlife suggest that 20-25 pairs of sandhill cranes, which can live for up to 20 years, are currently breeding in Ohio, plus another non-breeding group of around 20 cranes that live in the Funk Bottoms and Killbuck Marsh Wildlife Areas in Wayne County. Ohio’s sandhill cranes migrate to central Florida in late November, returning to their Ohio breeding territories in March. Several of Ohio’s sandhill cranes have been captured by Ohio Division of Wldlife staff, using a special net device, and wireless transmitters have been attached to the cranes so that their migration routes and ecology can be studied. Cranes typically fly at altitudes of around 2000 feet during migration, but have been observed flying as high as 12000 feet.

The only other Ohio bird that may be mistaken for a sandhill crane is the great blue heron. Sandhill cranes are large wading birds, like herons, but they have a red patch on the top of the head that is actually skin, rather than plumage, and long feathers, called a “bustle”, that overhang their rumps. Cranes fly with their necks and legs outstretched, whereas herons fly with bent necks and their legs tucked in. Cranes have grey plumage, as shown in the photo above, taken in winter in Florida, but they often preen by rubbing mud into their feathers, which stains their plumage brown or reddish, depending on the soil and the amount of iron in it. Young cranes, like the one seen in the Geauga County family photo, have brown plumage and eyes that are brown; adult cranes have reddish eyes.

Cranes are opportunistic feeders, eating fish, frogs, snakes, aquatic invertebrates, agricultural grain and other plants and small animals. The dragonflies I had been seeking earlier in the day would be tiny but nutritious morsels for sandhill cranes, which build their large nests in wetlands and engage in animated, elaborate courtship displays. The area south of Burton in Geauga County, near the headwaters of the Cuyahoga River, includes hundreds of acres of open marshes, especially in the Nature Conservancy’s White Pine Bog Forest and the area north of Snow Lake, providing excellent habitat for these impressive birds.
