Three blocks away from our house is a scrappy little pond, the Tanyard Brook Reservoir, completely enclosed by a barbed-wire topped chainlink fence and a mishmash of native and invasive shrubs and vines. There are keyhole views through the fence that reveal muddy banks dotted with litter, and a surprising array of wildlife. I’ve seen muskrats and a mink, mallards, mergansers, egrets, and the odd cormorant. In spring there’s a nesting pair of Canada geese, box turtles that somehow make it up concrete embankments and through the chainlink to cross the street, as well as a frog chorus, and a siege of black-crowned night-herons. Somewhere around a dozen of those guys (and gals) stick around all summer (I’m sure the frogs and turtles do too) and entertain me on my dawn dog walks by sitting hunchbacked and completely still. — Doesn’t take much to halt my forward progress before I’ve had coffee. Yesterday I counted nine. Today I could only spot four. Apologies for the terrible iphone photos but they do resemble my own dim and bleary-eyed view.
Here’s what I’ve learned about black-crowned night-herons: Adults are mostly gull-gray except for their black back and crown, and pretty white plumes like streamers trailing from the back of their head; females are a little smaller than males, and juveniles, up to 3 years old, are spotted brown. They hang out in communal groups and do most of their feeding at night — probably elsewhere because there’s no way this sorry spot can support so many herons. We’re within their year-round range here but the herons will disappear in the fall, as they always do, to spend winter on saltier water, maybe further south.
Any cool wildlife in your neighborhood?
