The worm stomping wood turtle is smarter than you think
Once upon a time, the wood turtle was the most common freshwater turtle in eastern Massachusetts. Today it is in severe decline. Naturalists Louis Agassiz and Henry David Thoreau documented their observations of this reptile in the mid-1800s.

Runners of the world, unite! Racers establish the People’s Republic of Danehy Park, if only for an evening
The third annual Guinea Pig One Mile race drew 175 runners — though none were actual guinea pigs — to the track at Danehy Park Saturday. The free run was organized by 25-year old Alex Sharp and his friend Ethan Weiner, 24. Sharp said it wasn’t so much a race as a revolution. “Our generation […]
Resilient red-tailed hawks face new threat
The red-tailed hawk (Buteo jamaicensis) is the most common hawk in the United States, with about three million breeding birds residing in North America today. They are also one of the largest North American birds: up to 24 inches long with a wingspan of nearly four feet. Their excellent eyesight helps them spot movement of […]
The many names of the wood louse

The once familiar bobolink now in decline
A reader asked me recently about ground-nesting birds. Here is the story of one such bird, the bobolink. Bobolinks (Dolichonyx oryzivorus) breed in open grasslands and prairies. When European settlers arrived in North America, they cleared forests for hayfields, pastures and farms. Bobolinks, native to the Americas, thrived in hayfields, which were plentiful even near […]
If only humans could breathe like yellow-rumped warblers
Mammals, including humans, inhale oxygen and exhale carbon dioxide, which sounds like a fairly simple process. But compared to birds, we’re very inefficient. When we breathe, we inhale oxygen-rich air into our lungs. This fresh air mixes with old oxygen-poor air already in the lungs. When we breathe out, we breathe out this old stale […]
Horrid Zale moths aren’t so horrible
One of my favorite Zale moths is the Horrid Zale moth, worthy of note for its name alone. If you have only ever read about Zale moths, including now, you are probably mispronouncing the name. You might think zale rhymes with tale, but it is actually a two-syllable word that rhymes with ballet, pronounced zah-lay. […]
