In less than a decade, the invasive Viburnum Leaf Beetle (Pyrrhalta viburni) has spread throughout most of New York State. They devour the leaves of viburnum species, key understory plants of our woodlands; a couple years infestation can kill the plant. I’ve seen the damage they do in Prospect Park, skeletonizing every leaf on a bush. In Brooklyn Bridge Park they’re trying to control things by hand.
But this was the first time I’ve run across one of the adult beetles. Yesterday in Prospect Park.
Because the assumption “pigeon” may usually be correct, but it isn’t always. Something about that silhouette…Peregrine Falcon (Falco peregrinus).At the top of 1st Avenue. You may remember that on January 1st, I found a pair of Ravens (Corvus corax) courting near here. Lately, four Ravens have been seen in the area, so presumably the nest-building seen in March led to good things, the first Ravens born in Brooklyn in… forever? Traditionally a species of highlands, Ravens are now adapting to urbanity. (I’m still hunting for a picture of the family.) But on that first day of the year, I also saw a Peregrine, streaking down 39th St. Good continuity. The Peregrine is traditionally also a bird of highlands, nesting on cliff faces, but following their reintroduction have taken surprisingly well to the canyons of cities.

Sunset Park is buttressed by a rough stone retaining wall that has become the home of numerous lifeforms. Above is the southwest-facing flank. Here’s the northeast wall, along 41st St. That’s where all the following were found:The presence of lichen, which doesn’t tolerate pollution, means the air here is relatively good. Indeed, elevated near the top of the Harbor Hill Moraine, the park catches the harbor breezes very nicely.There are numerous clumps of Scotch Moss (Sagina subulata), which isn’t a moss but rather a flowering plant.Haven’t yet figured out which fern this is. A spleenwort perhaps? Virginia Creeper (Parthenocissus quinquefolia).The caterpillar of the Sycamore Tussock Moth (Halysidota larrisii). Wikipedia says these can cause hives; this Auburn entomology page says nix to that, while listing other “stinging” caterpillars.’
“Stone wall, Sunset Park ……… $50,000″ from the May 10, 1906, edition of The City Record. Would love to know where these stones came from.

A Common Kestrel (Falco tinnunculus), the “dapple-dawn-drawn-falcon,” as Hopkins alliterated to the nth degree, hovering over the Northumberland beach. Hopkins’s poem The Windhover, although another of his mash notes to his Invisible Boyfriend, captures something of the impression made by these birds hovering with head to the wind and eyes to the ground, searching for prey. But then so does the non-canonical nickname, cited in Robert Macfarlane’s Landmarks, of “windfucker.”The first bird pictured is a male. This is a female, looking like she’d made a splash, paralleling the edge of a golf course near Bamburgh Castle.Hover-hover-hover-hover, swoop down on prey or swoop down to take up another hovering position further along. Lovely to watch them in action. (I was not quick enough to get a picture of one perched on a sign warning of the dangers of unexploded ordnance.)A third sighting was along the flank of Edinburgh’s monument-studded Calton Hill. We had just descended and were looking up to from David Hume’s tomb.
The American Kestrel (F. sparverius), which is a more colorful bird, does the same thing. The grasslands at Floyd Bennett Field are one of the best places to see them do this in the city.

As we neared the near-end of our first day’s walk along the Northumberland Coast, we spotted two swans in the distance. One was a familiar Mute Swan (Cygnus olor), invasive in the U.S., but native in the UK (and very present on the Tweed, where we started our walk) and the other, pictured below, a Whooper (C. cygnus).Note the projection of yellow below the nostrils, a good field mark when comparing with the similar looking but smaller Tundra or Bewick’s Swan (C. columbianus). Whoopers are general seen in the UK during migration, so this one was late or dawdling, with only a few breeding in the north. (The North American Trumpeter Swan (C. buccinator) is closely related but has a black bill.)
Less of a quiz than a mystery, to me anyway. Spotted this one in the Royal Botanical Garden. What is it?

Stinkhorns in Sunset Park. Genus Mutinus, but I’m not sure of the species, caninus, ravenelii? These are not all that unfamiliar in the urban context: mulched areas of parks are a good place to find them. These mushrooms, of the Phallaceae family, are atypical fungi: they produce a stinky slime to attract flies, who then help distribute the fungal spores. The flies buzzed off when I took the pictures.
