Salt marshes, with their varied habitats, host a wide variety of life forms. Rocky Point Marsh is no exception. Dozens of bird species have been observed over the years and they are by far the most visible of the marsh’s visitors. Insects abound and quite a few are easily visible, particularly butterflies, dragonflies and grasshoppers. Smaller insects will reveal themselves to close observation; disturbances in the water’s surface will also reveal fish going through their daily survival routines. Various crustaceans and mollusks are also to be seen.
For the purpose of this blog segment, I have very loosely defined Rocky Point Marsh as everything lying within borders defined by Rockaway Park Boulevard and Beach 201st Street, to the south and west, respectively (note that all compass points are “approximate”). The far-east border is delineated by the jetty at that end of the cove; the jetty then runs back into Rockaway Park Blvd. at Beach 193rd Street. The marsh’s northern side is fronted by Jamaica Bay.
A variety of conifers and broadleaf trees, most relatively young, surround the marsh on the higher elevations. Everything from algae to seaweed can be seen in wet and muddy areas, while a variety of wildflowers can be seen in the meadows. Grasses and vines abound with some rather tangled areas on the western fringes.
At the end of October 2012, a large amount of driftwood and manufactured lumber was deposited on the western edges of the marsh as a result of Super-storm Sandy. With two years of natural growth added, formerly interesting areas such as these are extremely treacherous and are best avoided.
Mammal signs have been observed, but most are nocturnal types and rarely seen during the daytime. Aside from natural residents such as the Northern Raccoon and Eastern Cottontail, invasive feral cats, irresponsibly released into the wild by humans, are also on the prowl for a meal.
These images were created during August and September, 2104. I must also apologize for not being able to identify some of the creatures shown here.
The Primrose Moth (Schinia florida) is rarely seen, but when it is seen, here is where to look. Tony found this tiny treasure recently and was kind enough to forward the image and some information regarding this little guy from Mr. John Himmelman. Timestamp: 08-21-14, 0955.
One of the most common and beautiful of all butterflies is the Monarch (Danaus plexippus). The Monarch has been known to fly 2,000 miles or more during migration from North to South America and has also been seen in Hawaii and Australia. This specimen was photographed in the woods on the western edge of the marsh. Timestamp: 09-20-14, 0811.
A Rubbed Dart (Euxoa defers) perches atop Seaside Goldenrod (Solidago sempervirens) on the far western extremes of the woods that enclose the marsh. Seaside Goldenrod is part of the Aster family, one of the world’s two largest plant families. Timestamp: 09-26-14, 1221.
This stand of Seaside Goldenrod is also host to two different insect species (aside from the two seen in the upper left of the image, note the smaller one at right), both of which remain unidentified. Timestamp: 09-26-14, 1407.
This odd-looking fellow is also among the unidentified. Aside from using its legs to move from place-to-place, this little guy also “hopped” about 8-inches as I approached closer. Note how well his color helps him blend into the sand. Timestamp: 08-09-14, 0910.
Another insect perfectly-colored to blend in with his surroundings presented himself for a portrait. This Grasshopper was flushed ahead of me as I walked through some tall grass just behind the dune-line. Using an internet source, it is tentatively identified as a Mottled Sand Grasshopper (Spharagemon collare). Timestamp: 09-20-14, 1056.
This school of Striped Killifish (Fundulus majalis) is seen feeding on the carcass of a defunct Horseshoe Crab (Limulis polyphema). The crab was situated in the flooded section of the marsh. Timestamp: 08-09-14, 0914.
Strike!! A Snowy Egret (Egretta thula) takes prey from inside the marsh pond. It is quite probable that the fish he has taken is a Striped Killifish, as seen in the image above. It is not impossible that one of the fish seen above, feeding on the Horseshoe Crab, is now a meal for the Snowy Egret. If so, this is an excellent example of the “food chain” in action. Timestamp: 08-30-14, 1411.
Gulls are by far the most common birds seen at Rocky Point Marsh. Greater Black-back, Ring-bill, Laughing and Herring Gulls are often seen, sometimes in relatively large numbers. Here we see a specimen of the latter bird (Larus argentatus), casting a wary eye at the photographer. Timestamp: 08-23-14, 1107.
One of the larger Plovers, these Black-bellied Plovers (Pluvialis squatarola) were part of a group of three photographed in the surf, just outside the marsh. Note the bird at right, which is more mature and therefore sports a partial black face. Timestamp: 08-23-14, 1111.
A fairly secretive bird, this Black and White Warbler (Mniotilta varia) was seen in the woods on the western edge of the marsh. This particular bird appears to exhibit the plumage of the female of the species. Timestamp: 08-13-14, 0831.
As recently noted on this blog, there has been a surge in Osprey (Pandion haliaetus) sightings throughout August and into September. This handsome fellow was observed and photographed on the morning of August 9, 2014. Timestamp: 08-09-14, 0938.
This US Air Force Boeing C-17 Globemaster III is in the landing pattern for JFK as part of the support flight for the President of the United States, during a recent visit to NY City. The C-17 weighs 585,000 pounds at takeoff and can carry 102 paratroops, or up to 80-tons of cargo. Since it can refuel in the air and land on short runways, this aircraft can deploy nearly anywhere in the world. Timestamp: 09-20-14, 1039.
Rocky Point isn’t the only section of Gateway NRA meriting special attention from birders and students of the natural world. This White-eyed Vireo (Vireo griseus) was spotted for just a few seconds, while the camera laid in wait at the pond below Battery Harris East, in Fort Tilden. It was my first sighting of this species. Timestamp: 08-31-14, 1558.
One week later, on September 6, a walk along the shore in Fort Tilden revealed another new species for my life-list. This Whimbrel (Numinius phaeopus), with its distinctive downward-curved bill was observed closely for nearly half-an-hour. Timestamp: 09-06-14, 1048.
A very common year-round resident at Gateway NRA is the Northern Mockingbird (Mimus polyglottos). This particular specimen is in the final stages of molting, which accounts for its very disheveled and scruffy appearance. He is perched on the guard rail that sits atop the casemate at Battery Harris East. Timestamp: 09-06-14, 0915.
Credit where it’s due:
Special Thanks to Tony for the photo of the Primrose Moth and to Mr. John Himmelman for the accompanying information. Thanks also to Rich for helping with the identification of the Rubbed Dart. Any errors of fact or omission are mine alone.
Published works consulted for this posting included the following:
“The Peterson Field Guide to Birds of North America”, by R.T. Peterson. 2008, Houghton Mifflin, ISBN9780618966141. This is THE classic work by the legendary Roger Tory Peterson. I have two versions; the cited volume includes both east and west field guides between the covers of an enlarged-format book. Simply stated, no serious birder should be without a copy.
“The Sibley Guide to Birds”, by D.A. Sibley. 2000, Knopf, ISBN 9780679451228. Building on Peterson’s work, David Allan Sibley took the idea a step further and this wonderful title is the result. This enlarged volume also covers eastern and western North America, combining two existing field guides. If you have Peterson, you should also have this!
“Mammals of North America”, by F.A. Reid. Peterson Field Guides, 2006 Houghton Mifflin, ISBN 9780395935965. Roger Tory Peterson started something that spawned dozens of field guides for the student of nature, including this title. Profusely illustrated, it also features images of mammal tracks.
Peterson First Guides: “Butterflies & Moths”, by P.A. Opler. 1994, Houghton Mifflin, ISBN9780395906651.
Peterson First Guides: “Wildflowers”, by R.T. Peterson. 1986, Houghton Mifflin, ISBN9780395906675.
Peterson First Guides: “Fishes”, by M. Filisky & S. Landry. 1989, Houghton Mifflin, ISBN9780395911792. All of the above titles are small primers on their respective subjects and are by no means comprehensive. They are extremely economical, although narrowly-focused.
“Field Guide to Insects and Spiders”, by L. Milne & M. Milne. 1980, Knopf, ISBN9780394507637. A fine guide covering only a small portion of a vast subject, this book should be one of several on the subject in the naturalist’s library.
“Field Guide to Wildflowers, Eastern Region”, by N.C. Olmstead, W.A. Niering & J.W. Thiret. 1979, Knopf, ISBN0375402322. In the same style as the book above, this title only scratches the surface. Regardless, as a novice I have found this a useful addition to my reference library.
“The Sibley Guide to Trees”, by D.A. Sibley. 2009, Knopf, ISBN9780375415197. Mr. Sibley doesn’t only paint birds! This beautifully-illustrated and hefty tome has helped me solve a mystery or two.
