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 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 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 [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 I was rather surprised to hear a soft, kittenish mewing as I walked through the park. Sure, I see free-roaming cats around the neighborhood from time to time but I can’t think of a single instance when I’ve spotted one in the park during daylight hours, and I’m in the park at […]

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 […]
