BY KIERAN LINDSEY, PhD Just in case readers assume the title of this post is a typo, let me assure you it is not. I’m fully aware that the photos featured here are of mute swans (Cygnus olor) but, like any wordsmith worth her salt, I can’t resist indulging in a little harmless wordplay. As you’ll […]

BY KIERAN LINDSEY, PhD A scientists’ work is never done. That’s because there’s always another layer to peel away, another stone to turn, another angle from which to view the situation. Case in point — about 200 years ago, Charles Darwin made the connection between the size and shape of a finch’s beak and the availability […]

BY KIERAN LINDSEY, PhD   Like Water Off a Duck’s Back — That tried and true adaptability adage is an apt observation for just about any species of waterfowl, thanks to their liquid-resistant outer contour feathers, but in the case of Mallards (Anas platyrhynchos) it’s also metaphorically germane… because this is one plucky duck. I won’t […]

BY KIERAN LINDSEY, PhD How often do you come across a bird so dee-lightful, so dee-lectable that it captured the attention of characters as disparate as W.C. Fields and Cole Porter? Quite often, actually, because chickadees (Poecile spp) are far from rare in North America. In my own little corner of the world, a historic neighborhood […]

BY KIERAN LINDSEY, PhD Watching a white-breasted nuthatch (Sitta carolinensis) cascade along the steep slope of a tree brought to mind the playground at Oakville Elementary, and made me wonder if the species’ iconic bottoms-up foraging style is the result of a dare. The far corner of our grade school property was the site of many […]

BY KIERAN LINDSEY, PhD [Thanks to Lafayette Square residents Jim and Carolyn Willmore for reporting a brown creeper sighting near the Cook Pavilion of Lafayette Park.] On frosty mornings, Mercury is uncharacteristically slow to leave that snug thermometer bulb… and I can’t say I blame him. I’ve been in no hurry to leave my own cozy […]

BY KIERAN LINDSEY, PhD It seems to happen once each century. In 1775 the Redcoats showed up in Boston, the Beatles made a big splash about 200 years later in 1964, and in the sweet-spot in-between the House Sparrows (Passer domestics) arrived. It’s difficult to believe, given current controversies and political grandstanding, but for a long time […]

BY KIERAN LINDSEY, PhD Sometimes the grass really is greener on the other side of the fence, especially if your yard-care ethic is benign neglect, and your neighbor is a wannabe greenskeeper. Generally speaking, though, the sentiment behind that familiar grassy idiom is sound—we humans tend to value what others have more than what we ourselves […]

BY KIERAN LINDSEY, PhD I was just trying to help, I swear.  In fact, the primary directive in wildlife rehabilitation is: First, do no harm. But the indignant male Northern Cardinal (Cardinalis cardinalis) I had just lifted out of a shoe box clearly interpreted my attempts to do a thorough but gentle intake exam as disrespectful. […]

BY KIERAN LINDSEY, PhD There’s been a marked decline in the number of sunspots over the past decade or so. That’s what NASA scientists say, and I have no reason to doubt their research findings. Luckily, I haven’t observed any reduction in the terrestrial version of this phenomenon. Hardly a day has passed lately when I’ve […]
