Neither rain nor any weather possibility or high East Pond levels could stop us. We thank our amazing leader, Keith, for finding so many exciting birds for us. We appreciate it all. The skippers skipped away very quickly, and only one Pearl Crescent was cooperative. We also saw Green Darners and one Black Saddlebags.

Twelve birders spent a delightful morning at Cupsogue Beach County Park with Eileen Schwinn, an expert Suffolk County birder who has logged many hours at this location. We started the day with a scan of the saltmarsh from the parking lot. Both Saltmarsh and Seaside Sparrows were seen, as well as a Willow Flycatcher taking advantage of a large hatch-out. We then did a brief sea watch from the platform leading out to the beach; it yielded a few shearwaters, likely Greater or Corey’s, but they were too distant to identify with certainty. On the roadway out to the bay, a Merlin was observed, along with several passerines.
We arrived at the bay about two hours before dead low tide and found an abundance of terns, gulls, and shorebirds on the sandbars and mud flats. Hundreds of Common Terns and about a dozen Royal Terns were present, in addition to a good variety of shorebirds. We were delighted to see a Marbled Godwit foraging on the edge of Spoil Island, and a Pectoral Sandpiper was spotted near the area favored by the Royal Terns. Aware of an approaching storm, we wrapped up around noon and enjoyed lunch together at the snack bar before departing.

Nineteen Linnaeans and botany enthusiasts gathered on a warm sunny morning to wander in available tree shade and light breezes around the Pool and briefly into the Ravine of northern Central Park. Many participants commented on the broad knowledge and enthusiasm of walk leader Regina Alvarez, whose experience in Central Park and in teaching is an excellent combination for transmitting information about the plant life of the Park and the way it has been managed over the years.
She started by lending magnifying loupes to participants, explaining that a jeweler’s loupe at 10x would be best for field study. She demonstrated how to use them by bringing the loupe quite close to the face and resting it against the cheek to hold it near the eye. The object to study must be very near the bottom of the glass.
Our first stop was at a hawthorne tree with quite a bit of cedar-apple rust, which exhibited as small, ball-shaped, reddish clumps with short hairs or tentacles, but is actually a fungus.
She pointed out which plants are native, which non-native, and which invasive. For example, we quickly encountered pokeweed, which is native and produces berries that birds love but are highly toxic to humans. (You can make ink with them.) In contrast, porcelain berry, a non-native invasive from temperate Asia in the grape family, should always be quickly removed from gardens and other habitats, as it will overwhelm and destroy native plant life.
The pokeweed and deadly nightshade sparked a discussion about foraging and the risks to an inexperienced forager. In general, foraging is not advisable in an ecosystem like that of Central Park, which would suffer greatly if thousands of visitors took up the practice.
Virginia knotweed (native) also known as touch-me-not, offered an amusing opportunity to demonstrate seed dispersal, with the seeds popping off and flying to quite a distance. Birds are also fans.
A young black cherry tree’s bark (native) exhibited prominent horizontal lenticels, or striations, that allow for gas exchange—that is, for the plant to breathe. As the plant grows older, as seen lower on the trunk, it develops what looks like burnt potato chip skin. The berry of this tree is beloved by birds and used for the black cherry flavor of soft drinks.
We observed a tulip tree (native) that demonstrated an ability to self prune, with lower shaded branches falling off as the tree grows, leaving a faint mark on the trunk that eventually fades. It is one of our tallest trees, and its long, straight trunk is made of a soft wood that is great for telephone poles, beams, and dugout canoes.
A large oak tree (native) near the birdbath area of the Pool was a fine example of a keystone species—that is, one that many other species depend on thanks to the enormous number of insects they host.
Burdock (non-native) was an example of a biennial, an individual plant with a lifespan of just two years.
The spice bush is a native wetland shrub that offers a fruit high in lipids to birds; it is a form of metabolic energy for migrating birds that is preferable to fruits loaded with sugar. The leaves produce a compound, the spice scent or flavor, that is a predator defense mechanism.
We came upon mugwort, also not native, which was probably brought over by colonists as a medicinal plant. Mugwort, among other plants, produces compounds to deter insects; this can create a detectable odor, which wanes by late summer, after plant reproduction has occurred. Mugwort is an invasive species, taking over open sunny areas.
In the Ravine we spotted some native hydrangea being visited by a native bee. Regina explained that native wild bees are critical for “buzz pollination,” a form of pollination that domesticated bees (honeybees) cannot perform, in which the bee vibrates to dislodge pollen. Plants in the tomato (nightshade) family require this type of pollination to reproduce.
We encountered poison ivy (native), reaching onto the path on a wooden bridge in the Ravine. Regina explained that the Park has a policy of managing rather than eradicating this plant, which produces berries popular with 60 species of birds, as well as the urushiol oil that stimulates an allergic reaction in approximately half the people who come in contact with it.

We had a wonderful day of birding on Staten Island. Our leader, life-long Staten Islander Howie Fisher, started our day off at Conference House Park, where the highlight was a White-eyed Vireo. From there we went to nearby Joline Avenue Beach, where we had the days most spectacular birds; Caspian and Royal Terns and seven Brown Pelicans! Our next stop was to see the annually nesting Purple Martins which are always a treat to see. Our last stop as a full group was to Wolfe’s Pond Park, where we were hoping to see the Neotropic Cormorant that had been around recently, but we had no luck with that bird. A few participants made one last stop, at Oakwood Beach, and we were treated to seeing a Little Blue Heron and a Marsh Wren.

On this beautiful late spring morning in Van Cortlandt Park, over one thousand acres of nature and park space in the Bronx, the group saw a nice variety of birds, bugs, and several other animal species, including two types of snakes and an Eastern cottontail. The participants were excited to see the Silvery Checkerspot, one of twelve different butterflies and moths seen on the trip. Ken Chaya, naturalist and the day’s walk leader, also pointed out various interesting beetles, grasshoppers, and other bugs that could easily be overlooked. The bird highlights of the walk were a Scarlet Tanager, a Green Heron, and a perching Eastern Kingbird, which provided a nice photo op for the nature photographers in the group. It was also exciting for the group to see a nest of hungry baby barn swallows being fed, a nice reminder that as spring migration closes, the peak of nesting season for many local bird species is here.

With spring migration winding down, the number of species we saw today was the lowest for any Tuesday walk of the season. They included only one warbler, but it was exciting to see nesting Wood Thrushes and Eastern Kingbirds as well as our resident Great Horned Owl, Geraldine. Many thanks to Kevin, who led all the spring migration walks this season and to all our other volunteer leaders.

The final walk of the season took place on a sunny and mild morning. Birds of several species, including a Baltimore Oriole, were quietly building nests, while Warbling Vireos laid claim to territories with their songs. Among the highlights were a surprise flyover by an Osprey, an Eastern Kingbird at Turtle Pond, and Wood Thrushes in the Ramble. At the Point, a Blackpoll sang out, perhaps the last warbler of the season to leave.
