Nidification

Columba liviaIn the last week, I’ve seen House Sparrow and Northern Cardinal nestlings, gaping mouths squawking. It’s late in the breeding season, but some birds, especially the non-migratory locals who started early, may be on their second brood of the year. This Rock Pigeon (Columba livia) is using a train station window-well for its cliff-face nest. As of yesterday, there was one egg.nestMost of our House Sparrows (Passer domesticus) nest in out of the way cavities, notably street lamps. But occasionally you come across their large, messy nests out in the open. Here’s one on the Green-Wood fence.

Great Wall Addendum

Limax maximusLeopard Slugs (Limax maximus). An introduced species, thinking about making more of themselves. And what a process that is!

VLB Adult

Pyrrhalta viburni 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.

Always Check That Bird

IMG_3659Because the assumption “pigeon” may usually be correct, but it isn’t always. Something about that silhouette…Falco peregrinusPeregrine Falcon (Falco peregrinus).Falco peregrinusAt 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.

A Great Wall

wallSunset Park is buttressed by a rough stone retaining wall that has become the home of numerous lifeforms. Above is the southwest-facing flank. wallNEHere’s the northeast wall, along 41st St. That’s where all the following were found:LichenThe 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.Sagina subulataThere are numerous clumps of Scotch Moss (Sagina subulata), which isn’t a moss but rather a flowering plant.fernHaven’t yet figured out which fern this is. A spleenwort perhaps? Parthenocissus quinquefoliaVirginia Creeper (Parthenocissus quinquefolia).Halysidota larrisiiThe 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.

Windhover

Falco tinnunculusA Common Kestrel (Falco tinnunculus), the “dapple-dawn-drawn-falcon,” as Hopkins alliterated to the nth degree, hovering over the Northumberland beach. IMG_2779Hopkins’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.”Falco tinnunculusThe 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.BamburghHover-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.)Calton HillA 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.

Sandstone and Basalt

IMG_3353Kind of hot for blogging, wot? Let’s take a dip in the North Sea: this is Greymare Rock, also known as Saddle Rock and the Whale’s Belly, just south of Dunstanburgh Castle. It’s made up of buckled layers of sandstone, the same sandstone used to build the nearby castle. IMG_3345 The castle itself, a ruin now, was built on an exposed ridge of basaltic Whinn Sill, a natural wall to the sea. Brilliant budgeting, that. IMG_3351The pale discoloration in the far distance on the cliff is guano from birds. The cliff hosts a nesting colony of Kittiwakes.
