Many bobolinks disappeared from the field of near Kalmar Reservoir when a farmer cut grass for hay. Where have they and their little ones gone?

Merrily swinging on briar and weed,
Near to the nest of his little dame,
Over the mountain-side or mead,
Robert of Lincoln is telling his name:
Bob-o’-link, bob-o’-link,
Spink, spank, spink;
Snug and safe is that nest of ours,
Hidden among the summer flowers;
Chee, chee, chee.

— First verse of the poem, “Bobolink,” by William Cullen Bryant

In mid-May, I ventured west to explore and photograph landscapes and wildlife in the Black Hills of South Dakota. The region is known for Badlands National Park, Mount Rushmore, Custer State Park, Wall Drug, Devil’s Tower National Monument, and Deadwood. …

Bicycles and Cycling

Long bike rides can be enjoyable and satisfying

Riding an imperial century is a primary goal for some recreational cyclists. Pedaling 100 miles may seem like a daunting challenge. But with good conditioning, planning, and a comfortable bike in good running shape, it can be fun and satisfying.

While I had pedaled hundreds of rides between one and 75 miles long, I rode my first three centuries during a 396-mile bike tour from Ely, Minnesota, into Wisconsin, and home to Rochester, Minnesota. Even though I rode the tour 25 years ago this month, it left an indelible impression in my mind. On the last day, I rode 105…


Bicycles, Randonneuring, and Adventure

Carry essential tools, supplies, and parts for long bike rides — just in case

Whenever I get on my bike, I usually carry a tire pump, inner tube, tire levers, and multitool. The longer the ride is, such as a 1200 km grand randonneur, the greater the risk of equipment failure. Mechanical problems can result in lost time and expense, such as paying for an Uber or Lyft ride or a bus or train ticket. So, it pays to prepare.


Birds, Birding, Nature, and Photography

How does a bird get a name like dickcissel?

Since spring of this year, I have witnessed and photographed large numbers of dickcissels in fields, meadows, and prairies near my home in Southeastern Minnesota. Some grassy fields are equally populated with bobolinks and meadowlarks.

Birds are named in various ways. For example, some are named for people, while others are named for similar birds. But the dickcissel is named for its primary song, which sounds like “dick-dick-ciss-ciss-ciss.” You can hear it here.

Believe it or not, indigo buntings are not blue

Some things are not as they seem. For example, prairie dogs are not dogs but rodents. Fireflies are not flies but beetles. A lead pencil does not contain lead but graphite. Likewise, male indigo buntings are not blue as they seem to be.

The feathers of male indigo buntings lack blue pigment. During the mating season, structures in the feathers of male birds reflect and refract light to make them appear blue. In winter, the males appear brown, as do the females year-round.
