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 Maybe Bobby McFerrin was a house wren (Troglodytes aedon) in a previous life. This thought popped into my mind when, after listening to On Being’s Krista Tippett interview the singer, I went out for a walk with my canine companion. We hadn’t made it too far down the sunny sidewalk when we […]

BY KIERAN LINDSEY, PhD Ever wonder why hens’ teeth (or any other kind of avian teeth for that matter) are rare? It’s because teeth are heavy. That’s a problem if you live life on the wing but can’t use a knife and fork to cut your meals up into easy-to-swallow morsels. A bird’s beak (aka bill) […]

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 [FYI… Feathered Feature is switching to a winter schedule of every-other-week posts. There are still plenty of birds in the park during the colder months but with everyone (that includes me) extra busy over the holidays, it seems like a reasonable time for semi-hibernation.]  . “Who cooks for you? Who cooks for […]

BY KIERAN LINDSEY, PhD [In honor of Halloween, a species dressed for the occasion!] Even though our cultural sings the praises of summer, it’s not my favorite season. I always welcome the crisp air, deeper blue (and, admittedly sometimes flat gray) skies, and red-orange-yellow leaf palette that arrives after the autumnal equinox. My appreciation of fall […]

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 […]
