Week 30 - Green-Wood Cemetery

While Brooklyn's coastal habitats are seeing a noticeable increase in southbound species (primarily shorebirds & seabirds), week 30 in Green-Wood Cemetery saw more subtle transformations.

I had assumed that the breeding season ended a few weeks ago, so was surprised to see: a recently fledged mockingbird, a recently hatched Chipping Sparrow and a robin feeding hatchlings on a nest near Sylvan Water.

A few warbler species have been trickling into the area with Yellow Warbler being the most visible. Northern Waterthrush has joined the earlier arriving Louisiana Waterthrush. The Solitary Sandpiper is no longer alone as it has been joined by Spotted Sandpipers.

There were quite a few botanics in bloom last week, helping feed the increasing number of pollinators seen around the cemetery. My favorite spots are still around Valley Water and a short stretch of plantings along Central Avenue. I also discovered that the plantings at the Civil War Monument was humming with insects. Most notably a large number and diversity of dragonflies were patrolling the east side of the monument.

It was interesting to note all the various species of garlic that have dropped their blooms (ready to sauté?).

I'm finally see some diversity in the skipper butterflies. Prior to last week I'd only been seeing Sachems skippers. These very small butterflies are difficult to separate, but I was able to photograph several Crossline and Zabulon Skippers last week.

The number of dragonflies throughout the cemetery has greatly increased. While many of those species are migrating through the area, several are locally breeding. The full list from last week is: Familiar Bluet, Swamp Darner, Common Green Darner, Comet Darner, Eastern Pondhawk, Twelve-spotted Skimmer, Great Blue Skimmer, Blue Dasher, Wandering Glider, Spot-winged Glider, Eastern Amberwing, Common Whitetail, Ruby/Cherry-faced Meadowhawk, Carolina Saddlebags and Black Saddlebags. The Common Whitetail does not migrate, but will mate, lay its eggs in the ponds (or a puddle), then die. The individuals we'll see next summer are those offspring beginning the cycle again.

One of my favorite moths is the tiny Ailanthus Webworm Moth. Often mistaken for a beetle due to the way they hold their wings close to their body, this beneficial, diurnal moth is easy to overlook due to its small size.

Here's a nice selection of frequently unnoticed bee species from last week.

I found a tiny, little clay "pot" attached to a plant stalk. When I learned that it was created by a Potter Wasp, I went down a rabbit hole trying to learn about these miniscule insects. I wanted to figure out which species created the beautifully crafted mud nursery. Most of the wasp species I'd observed were way too large. One that I photographed is the Mexican Grass-carrying Wasp. They don't make pots. The second wasp I had a difficult time identifying. Finally, I realized that it wasn't, in fact, a wasp. It was a look alike, probably evolved to keep potential predators from eating them. This was actually a fly called the Thick-headed Fly (Physocephala tibialis). Nature, man!

These are the trees I observed last week that have begun fruiting.

Finally, yesterday morning I encountered an Eastern Red Bat sleeping in the middle of Lawn Avenue. At first, I thought it was just a dead leaf and stepped over it. My friend Jim realized it was a bat and called me back. We weren't sure if it was injured or just fell from its roost and decided to stay on the road. We tried to coax it out of the road and onto the side of a large oak tree. It very vocally objected to our help and eventually flew up to a close tree where it remained for the rest of the day. Eastern Red Bats migrate in the Fall, so I'm not certain if this is a locally breeding individual or if their migration has already begun. The International Bat Conservancy has a lot of good information here.

Linnaean Society of New York

Dragonflies & Butterflies, Brookfield Park, Staten Island
Saturday, August 3, 2024
Leader: Seth Wollney
Description: Staten Island’s Brookfield Park was once the site of a municipal solid waste facility. Following remediation, more than 17,000 trees and 76,000 plants were planted before the park opened in 2017, attracting migratory birds and butterflies to the area. Four marked trails provide excellent hiking opportunities, and a mile of unmarked trails can bring you all the way to Richmond Creek. We will experience ponds, rivers, wetlands, marshes, and meadows at this safe and serene mid-island gem. The walk will focus primarily on insects, but interesting birds will also be noted. This is a leisurely walk primarily on flat, wide, paved roads with small sections of gravel paths, with frequent stops to observe butterflies and other pollinators at nectar-producing plants.
Registration: Anne Lazarus — amlazarus47@gmail.com

Jamaica Bay Wildlife Refuge
Sunday, August 4, 2024
Leader: Gabriel Willow
Description: The Jamaica Bay Wildlife Refuge includes over 12,600 acres of saltmarshes, freshwater and brackish-water ponds, upland fields and woods, an open bay, and islands. It is one of the largest bird habitats in the northeastern United States and a great place to observe the seasonal bird migration as well as resident species. This walk is scheduled for peak shorebird concentrations at Jamaica Bay and will likely include a visit to the East Pond, which may require mud boots to navigate comfortably.

Week 29 - Green-Wood Cemetery

Below are the highlights for week 29, July 15th through July 21st, in Green-Wood Cemetery. It was another week with some fairly miserable weather, so I didn't get out as much as I would have liked.

Beginning with the birds, there was suddenly a lot of very visible juvenile Gray Catbirds out exploring. I also just started noticing several juvenile Chipping Sparrows. The Chipping Sparrows are frequently parasitized by Brown-headed Cowbirds and I'll often see the adult sparrows feeding them around this time of year. I haven't observed any this year, but it just might be that I've spent less time looking due to the weather.

Our juvenile Red-tailed Hawk is still learning how to navigate the cemetery and relying on food from its parents. I'll frequently hear its squealing calls around "The Flats" when it gets hungry. I saw one of the adults perched in a huge oak tree with a freshly killed squirrel. It was making piercing whistled chirps, calling the young one in for breakfast. I never saw the juvenile fly in for the meal, but did hear many songbird alert calls in the distance, so figured it was not far away.

Some southbound migrants observed this week were Solitary Sandpiper, Baltimore Oriole, Orchard Oriole, Louisiana Waterthrush, American Redstart, Northern Parula and Yellow Warbler.

Most of the early blooming milkweed plants have gone to seed, however, one subtly fragrant species, the Swamp Milkweed is now adorning the cemetery with its pink flowers.

Butterfly numbers increased slightly last week with more Black Swallowtails, Eastern Tiger Swallowtails and Summer Azures fluttering about the cemetery. In addition, I saw my first Banded Hairstreak of the year during my Sunday morning walk.

A couple of the fruiting trees I noticed last week were Horsechestnut and Chinese Arborvitae (a type of cypress). Also, Nodding Onion is now flowering amongst the beds of Mountain Mint.

With the Dog Days of Summer come the churring songs of the cicadas. Over the past week the number of cicadas singing from the cemetery treetops has noticably increased. It should be of no surprise that the annual Cicada Killer Wasp colonies have also multiplied. There are several areas around Green-Wood with short grass and sandy soil that are preferred by these frightening looking but docile insects. This wasp paralyzes its prey, transports it to a subterranean burrow, where it then deposits its eggs for consuming by the growing offspring. Despite this gruesome strategy, the adult Cicada Killers are nectar eaters.

Here are a few other abundant pollinators observed frequently last week.

I've observed around 18 species of dragonfly and damselfly in Green-Wood Cemetery. Many of those are migrating through the area with probably less than half of them breeding here. Like the birds, the diversity of odonates seems to be increasing now with the arrival of the migrating species.

Finally, one insect that nobody is happy to see now is the Spotted Lanternfly. Some of the trees and shrubs have been blanketed with the tiny black and red nymphs, but now those young lanternflies are emerging into their adult form. One positive note is that I witnessed an immature Black-billed Cuckoo eating many of the nymphs. Now we just need to train all the other birds to eat them.
