The East River is NYC’s premier waterway and as founder of the LIC Community Boathouse and HarborLAB, I’ve made it my paddling home. At sunset, ferry boats filled with skyline gawkers will nearly flip to the west, and East River bridges set the scene for countless films. But for a kayaker, it’s the wilderness refuges of its islands and inlets that make this tidal strait endlessly fascinating.

Returning to Randalls Island from Governors Island in the Sunday morning calm after City of Water Day, Caroline Walker and I paddled through the outskirts of Hell Gate toward Mill Rock. I was admiring Great Black-backed Gulls at rest and Double-crested Cormorants perched on the island’s rip rap skirt while drying their wings when I spied something a bit different — a bird with the shape of a heron but markings similar to an American Woodcock. Caroline described it as “brindled,” which is pretty apt.

As we drifted past, a handful of cormorants and gulls took off while most ignored us. The misfit bird, however, walked quickly and deliberately into the brush that grew down from a turf mound to the rip rap line. It seemed to almost instantly disappear among the twigs and leaves. I didn’t have a camera.

After some research yesterday, I realized how lucky Caroline and I were! We had spotted an American Bittern. This species has fantastic camouflage for its reedy habitat, and so is rarely seen. Sadly, its population is declining rapidly with diminishing wetlands (though I’m comforted that its conservation status remains “least concern“). Good places to seek them are Pelham Bay Park (join Wild Metro for a volunteer day) and Jamaica Bay Wildlife Refuge. But they can pop up well away from salty shores. Prospect Park Lake, in the heart of Brooklyn, may have drawn this other one.

For those not lucky enough to glimpse this stealthy heron, there’s still a chance to hear its odd call, the second part of which sounds to me like someone repeatedly unstopping a PVC pipe. Strange that a creature would evolve to be invisible only to concurrently acquire a voice that earns it nicknames like “Stake Driver, Thunder Pump and Mire Drum.”

The American Bittern I observed was silent, so I have something to look (or rather, listen) forward to!

City of Water Day was another great success this year, thanks to Metropolitan Waterfront Alliance staff, volunteers, partners, and participants.

After some puttering around the island, eating delicious Vspot vegan empanadas,  and spending time with an amazing array of vendors, exhibitors, and fellow mariners, it was time to settle into camp.

We strolled past a rare American Elm tree and into Nolan Park. Girl Scouts of the USA interactive designer and artist Caroline Walker spotted this black crowned night heron in a tree. Noted nature illustrator Steve Sanford (Nature Conservancy, Field and Stream, Boys’ Life, Saltwater Fisherman) and I lingered with Caroline to observe this representative of the most widely distributed (five continents!) heron species.  It drifted down to lower branches to return the curiosity. After a few minutes, we mammals moved on.

Then, the little thing proved truly brave and inquisitive. It followed us over a tree or two to our camp site, and then came down! Throughout the night it poked around the dirt to feed, strolling among our supine bodies. Sometimes it would swoop over us quite closely, yet not aggressively —  apparently gusts from its wing beats once woke Steve.

I’ve never known this species to hunt on dry land, but perhaps it’s adapting to better exploit the safety of Governors Island’s canopy for nesting. After all, there are insects in the soil beneath the trees too. Still, I would love for any revamping of the island to include soft shorelines, restored wetland habitat, and other kindnesses to native creatures.

At points a second heron arrived and departed, to spar or flirt. Only when thus engaged did our friend caw. I’m too ignorant to know what was transpiring, but it wasn’t likely nest aggression — the adults of this species actually feed each others’ young. I’ll ask my friend David Burg of Wild Metro (and adviser to HarborLAB) to clue me in, and update this entry with an epilogue.
