I know you are not supposed to click your own Google AdSense ads, but recently there were two ads for purveyors of bird’s nest soup, and I had to go see what that was all about. I knew that bird’s…

the disjunct twinleaf

A favorite native plant in my wildflower garden is twinleaf, Jeffersonia diphylla. The flowers are similar to that of bloodroot, Sanguinaria canadensis, which I also have spreading all over nearby. But you can see where twinleaf gets both its common…

rapid junco evolution

I’ve written before about Dark-eyed Juncos (Junco hyemalis), a common little sparrow throughout much of North America. This species generally breeds at high latitudes (e.g., across Canada), or further south at higher altitudes (usually over 1500 feet/460 m). There it…

Over the weekend, an Ivory Gull (Pagophila eburnea) was found near Point Pelee, Ontario. The sighting of one of these birds in the United States always creates a sensation, because it is a bird of the high Arctic, and fewer…

brown creeper

crisp brown leaf, wind-blown flake of bark, falling from tree nope, wrong: brown creeper The diminutive Brown Creeper (Certhia americana) is notorious for being unobtrusive. Even the creeper’s sweet, clear, musical song can be frustratingly difficult to hear due to…

This past week I participated in one of several Christmas Bird Counts that I do annually. I’ve done counts here in Michigan on sunny, cloudy, snowy, rainy, raw, and balmy days, but never on a day that included all of…
