Yes, we have egrets
The larger Great Egret (Ardea alba) and the smaller Snowy Egret (Egretta thula) are sometimes found side-by side, making the size differential between them easy to see at a distance. For more detailed observation, especially in flight, the Great has a yellow bill and black feet, the Snowy a black bill and yellow feet. Note…

Tachinid
Most flies get very little respect. Perhaps it’s their hairy rumps? Or maybe it’s that their larvae are parasitic on caterpillars? But Tachinidae flies are also pollinators, and so the plants approve.

Two Gulls
Ring-Billed Gull (Larus delawarensis), one of the three species of gull found here in the city year around.Laughing gull (Leucophaeus atricilla), a summer visitor to the city. Named for their call, which sounds a bit like crazy-laughter. (The name “Black-headed gull” was taken.) These birds will soon lose their breeding plumage, which includes the black…

Blue Dasher
The Blue Dasher dragonfly (Pachydiplax longipennis) is common around our ponds and lakes, especially if there’s lots of vegetation in the water. The males have a chalky blue abdomen, with black tip. The females have no blue at all. But they do have tell-tale paired yellow streaks along their abdomen.Dragonflies of this species will often…

In Maria’s Basement
I’ve mentioned the Maria Mitchell Association on Nantucket in my previous posts without explaining much anything about it. In four decades connection with the island, I’ve been to their observatory, science center, and library many times. A friend of the family wrote the most recent biography. So I naturally assume that everybody knows who Nantucket-born…

Note especially this graf: “The new partnership also calls for the creation of a conservancy or friends group dedicated to the bay, to encourage philanthropy. Similar conservancies have helped other large parks in New York City, including Central Park in Manhattan…

Mud Cells
Two summers ago, a Black and Yellow Mud Dauber wasp built her nest in the Back 40 (inches). A new generation of these large, black-bodied wasps with yellow legs emerged in June of last year. This year I had one inside the house. Not here in Brooklyn, but at the family house in Massachusetts. This…

Two-Spotted in Brooklyn
One more species of lady beetle spotted in Brooklyn Bridge Park, on the catalpa trees, whose big leaves are sticky with aphid honeydew. This is the Two-Spotted lady beetle (Adalia bipunctata). There were several of them, so there must have been a recent pupation. This species is native to North American and Europe, making it…

Dog Days
Yesterday, I heard two cicadas whining at the northern end of the Promenade. These were my first of the year. Today I heard one in the back of the apartment, way back, beyond the Back 40 Inches. On a walk through the neighborhood, I spotted a couple of the huge cicada killer wasps (Sphecius speciosus)…

Banding Osprey, Part II
Osprey chicks can be too old to band, because as they near fledging, they may jump off the nest site prematurely to get away from the human who has climbed up to borrow them for a moment. If they aren’t actually ready to fly, this can lead to broken wings. This one, however, was a…
