Central Park Botany Walk with Regina Alvarez, 5/31/2025

Registrar:Ā Ā Anne Lazarus
Participants:Ā Ā 15
Weather:Ā Ā Cloudy early morning, then sunny, high 60 F.

May 31 was a perfect, sunny, mild day for a botany walk in the north end of Central Park. We met our wonderful leader, Regina Alvarez, who made sure we all had magnifying glasses.Ā 

We began our day by examining leaf galls of the Washington Hawthorn tree. Plants defend themselves against invaders by isolating them in these galls. The eggs andĀ Ā larvae develop in the galls, where they find nutrition and emerge at a later date as adults. Galls are specific for each tree. Adjacent to the Hawthorn tree were small plants in the buckwheat family. Buckwheats create a thin, leaf-like sheath around the stem, where the leaf blade attaches. Smartweed and Virginia Knotweed are in the buckwheat family. We examined the Smartweed without magnifying glasses.

We could have spent over an hour in this one spot because there was so much to see and examine. We were fascinated by the Bald Cypress. It is a conifer that sheds its leaves in the fall. This tree is monoecious, with both male and female flowers on the same tree. The female flowers are wind pollinated and develop into little cones, which we viewed in detail. This tree has ā€œkneeā€ projections from above the root. The reason for the knees might be related to oxygen access, but this is still being investigated. We learned that Bald Cypress trees growing in drier areas do not have ā€œkneesā€ā€”for example, the Bald Cypress of Strawberry Field does not have ā€œkneesā€.

The small plants that spend their lives close to the soil also play their role. We examined the humble English and the American (native) plantains. The base of our native plantain is red, but the English Plantain’s is white. These plants are dicots, but the leaf veins are parallel, like those of a monocot.Ā 

We then strained our necks to look up to the crown of the mighty Tulip tree. This tree loses its bottom branches as it grows taller and reaches for the sunlight. We learned that each plant species has its own strategy for survival and reproduction. Oaks are fine growing in the shade. An English Elm has been planted in the Loch, and has been placed in aĀ cage for protection.Ā 

A beautiful native birch is the River Birch. It can grow in difficult environments, and is a rugged tree with nutrients that attract a variety of birds. ManyĀ insect-eating birds also find nourishment in this tree. We examined many specimens of our native Sweet Bay Magnolia, Staghorn Sumac, Sassafras, and many other species. Ironwood trees create burls, a distorted outward growth on the trunk that forms from stress. The tree can survive well with a burl.

The London Plane tree is a hybrid of the American Sycamore and the Oriental Plane tree. It is infertile, but it can remove pollutants from the air.

We switched our attention to the tiny flowering plants that were floating in the Pool—Milfoil. It offers shade, fish cover, and habitat for invertebrates. Odonates are insect predators; they are attracted to the Pool. The tiniest plant that we saw was the Watermeal. It is rootless, but capable of spreading rapidly.Ā The Duckweed keeps aggressive algae under control, and the shoreline plants also stop nutrients from feeding algae. Blue Flag Iris is a native shoreline plant at the Pool.

Many flowering shrubs captured our attention. We were happy to observe a native Azalea shrub. A sign of spring is the Trillium, which we saw in the Loch. It is a spring ephemeral, like violets. Jewelweed was starting to bloom in the Loch. Another favorite is the Columbine; leaf miners were tunneling their way through its leaf tissue, and will eventually emerge as adult insects. We took photos of the leaves and flowers. A valuable plant with fruit that nourishes many bird species is the Pokeweed. Burdock, another interesting plant, has a two-year reproduction cycle. This plant is the inspiration for velcro!

Ferns are an important part of the Pool’s ecology. They produce spores, not seeds. The sporangia seen on the back of the fern’s fronds, or on a separate frond, hold and release haploid spores (that is, spores with unpaired chromosomes in the cells) as part of fern’s complex reproductive process. A variety of fern species grow near the Pool: New York Fern, Ostrich Fern,Ā Ā Royal Fern, and Christmas Fern are among them.

Central Park has both native and non-native plants. The native plants offer the nourishment needed by bees and birds; non-native plants like Mugwort do not attract bees and birds. Poison Ivy, a vine, is native and an important source of nutrients for our birds. It does not cover and choke the trees. Non-native Porcelain Berry does cover and harm the trees by choking them. It is in the grapeĀ family. Unfortunately, birds love the fruit and spread its seeds.

Lichen are not plants but, rather, associations between specific fungi and algae or cyanobacteria. The algae or cyanobacteria provide nutrients from photosynthesis for the fungi, and the fungi provide structure and protection. There are three common types of lichen: foliose, which we observed at close range, crustose, and fruticose.Ā Lichen appear worldwide and are a source of food for caribou.Ā 

Plant diversity can seem overwhelming. We learned so much during our outdoor classroom, and we look forward to returning to learn more.

Sterling Forest State Park with Tod Winston, 5/25/2025

Registrar: Lisa Kroop
Participants: 8
Weather: 51°F–57°F, clear with some clouds; 8 mph NW
Bird Species: 60

Birds were singing all around us as we gathered at the trailhead on the cul-de-sac of Ironwood Drive for our walk along the powerline in Sterling Forest State Park. The loudest was a Scarlet Tanager, and filling in between its songs were those of other birds, including Yellow Warbler, Common Yellowthroat, Ovenbird, Field Sparrow, Indigo Bunting, and a Blue-winged Warbler, with its buzzy trill.

We soon had our first sightings: a Blue-winged Warbler in the low shrubs; a Yellow Warbler, its bright plumage highlighted against the dense foliage of a nearby tree; an Indigo Bunting perched on a bare branch of a distant tree; and an Eastern Kingbird in the same vicinity as the bunting— sallying and displaying the white of its tail.Ā 

We proceeded to walk along the power line cut, starting in the southern section. Earlier, a few of us had seen a pair of Yellow-billed Cuckoos fly across the cut, and the group climbed the trail hoping to find them. We heard them calling as we walked, but didn’t manage to see them. We saw a flock of Cedar Waxwings flying overhead—the first of several flocks we spotted during the morning. Pausing at a high point, we observed a juvenile Red-shouldered Hawk flying in the distance, and a couple of participants saw a Common Nighthawk pass over and beyond the tree line.Ā 

We turned around and headed toward the northern section of the power line, accompanied by the continuing tunes of Prairie Warblers and Field Sparrows, among many other birds. Despite hearing their songs, it took a while before we were actually able to see any of them, but we eventually did, and with very good views. Tod picked up the song of a Louisiana Waterthrush and we pursued it along a side trail that veered into the woods. We didn’t find the waterthrush, but we heard a Worm-eating Warbler and found it at eye-level in a tree, and saw an Ovenbird close to us on the opposite side of the path.

Returning to the rocky power cut trail, we met a man who excitedly told us that he had just seen a bobcat, and showed us a beautiful photo. As we continued up the trail, we heard two Scarlet Tanagers singing back and forth, one high in a dead tree and the second much closer to us, perched in a low tree—we could see and hear both of them from the spot where we had paused along the trail.
Ā 
We met some other birders, who told us about an active Prairie Warbler nest. It took a bit to find it, but when we did, we also saw the protective mother in a tree nearby. Not surprisingly, we didn’t spot the bobcat.

After we turned around and headed back down the trail, a Pileated Woodpecker flew across the power cut in front of us, a Broad-winged Hawk flew across the cut behind us, and we observed a Ruby-throated Hummingbird perched on a bare branch ahead of us—one of two hummingbirds of the day. Near the bottom of the trail we heard another Worm-eating Warbler and spotted it perched on top of a horizontal branch, to the delight of all.

Cerulean Warbler and Hooded Warbler were the final highlights. As we passed through the patch of woods on our way back to the cars, some of the group heard a Cerulean and caught a glimpse of it as it was chased out of the nesting territory of a pair of American Redstarts, a ruckus which we all saw and marveled at. Hearing the Hooded Warbler from our cars as we drove away on Ironwood Drive, we stopped and walked down the trail to track it down. Persistence paid off, with a measure of good luck, and all were able to get their eyes on the bird.

While this power cut location is known for Golden-winged Warblers, the species hasn’t been reported this year, and we did not come upon one, or any of its hybrids. Instead we focused on all the other birds, saw and heard many, enjoyed the cool weather, the good company, and a fantastic leader. Many thanks Tod!

Shawangunk Grasslands NWR and Wallkill Marsh with Tod Winston, 5/24/2025

Registrar: Christina Black
Weather: Cloudy and cold with a few showers, temperature in high 50s
Participants: 15
Bird Species: 66

Tod Winston led us on a lovely day of birding in several locations, with some of our warm coats coming off as the day progressed. The report here is provided by Tod:


Our day of birding started rather coolly at the Shawangunk Grasslands, but thanks to a warning from Christina, we had come well prepared. And, mercifully, the unseasonably crisp weather did not deter the birds! We quickly found the principal targets of the trip, including singing and displaying male Bobolinks, singing Eastern Meadowlark, and cooperative nesting Eastern Bluebirds. The small and reedy-voiced Grasshopper Sparrow proved a bit scarcer this year… but after a bit of a stake-out, sharp eyes spotted a perched and singing bird in the distance. As we made our way down the trail to check the wooded border of the grasslands, we watched Barn Swallows and Purple Martins swoop over the fields, found an American Kestrel pair perched together in the distance, and heard Field Sparrow and Blue-winged Warbler singing faintly from the opposite side. A second Grasshopper Sparrow granted us a good view, energetic Bobolinks were plentiful, and we got looks at singing Willow Flycatcher, Song Sparrow, Yellow Warbler, Common Yellowthroat, and both male and female Red-wingedĀ Blackbird.

A saunter up the refuge’s driveway allowed closer inspection of the refuge’s Purple Martin colony, and also provided views of several Eastern Kingbirds, Tree Swallows, and more Willow Flycatchers. (Alas, no Alder Flycatcher was heard this year.) The pond and woodlands then supplied a slightlyĀ different set of birds, including White-breasted Nuthatch, Cedar Waxwing, American Redstart, Ovenbird, and a still elusive but more audible Blue-winged Warbler. Singing House Wren and Eastern Wood-Pewee also made cooperative cameos, and the high, ringing echo of a Blackpoll Warbler reminded us all of the passage of spring migration.

After a relaxed lunch in the gazebo, we headed off through the neighboring Blue Chip Farms property. This area did not prove as productive as it has in past years, but we did add a few more species to our day list, such as Cooper’s Hawk, Chipping Sparrow, and Warbling Vireo. Savannah Sparrows, however, were not to be heard.
Ā 
Liberty Loop in Wallkill Marsh, our final destination of the day, has beenĀ in recent years a reliable spot for nesting Sandhill Crane and Common Gallinule. Despite much scanning and listening, however, we did not detect either of these species–but were ultimately rewarded with a number of other interesting wetland and scrub birds. From the parking lot, we spotted one Bank Swallow swooping over the marsh and heard the gurgling song of the Marsh Wren; and then, while waiting out a sudden rain shower down the street, we glimpsed a Great Blue Heron. Happily, the rain then abated, permitting us a lovely walk in the dappled shade along the refuge’sĀ stream. Several Wood Ducks flew by, as did a Belted KingfisherĀ and two Green Herons. A Swamp Sparrow sang its wobbly trill, and a very skulky but ultimately cooperative singing young male Orchard Oriole provided a hard-fought thrill. His chattery song gave usĀ  a useful comparison to several Baltimore Orioles in the vicinity. We also again heard a sharp “ping ping ping” call, which we had earlier concluded was the sound of one or more Spotted Sandpipers, seen near the parking lot. As noted by one astute longtime birder in the group, however, we had not actuallyĀ seenĀ any Spotted Sandpipers. This time, however, the “ping ping ping” very clearly issued from the open beak of that multi-voiced scoundrel, the Red-winged Blackbird! (Birds always have something new to teach you. It keeps things exciting ;-).)Ā  We then heard the “wheep!” of a Great-crested Flycatcher and the distant “chebek” of a Least Flycatcher, and finished off our day with a group of excitedly singing and chipping male and female Indigo Buntings.

All in all, we ID’d 66 species on the trip. You can view that complete list below (in addition to three trip checklists in the eBird Trip Report).

Central Park Spring Migration Walk with Richard Davis, Alan Drogin, Alice Deutsch, and Kevin Sisco, 5/20/2025

Registrar: Steve Holleran
Participants: 41
Weather: Cool and partly sunny
Bird Species: 68

Forty-one birders set out in three groups to explore the Ramble, Turtle Pond, and Reservoir areas of the park, with a combined total of 68 species observed. Notable sightings included a Bald Eagle, Osprey, and Bicknell’s Thrush, as well as 18 species of warblers!

A couple of our more unusual observations involved non-avian players. The first case was a small flying squirrel that was under attack by a group of jays. Twice we saw it knocked down out of a tree, both times gliding down to the base of another tree, where it climbed back up. We didn’t see the end of the drama, but we think it may have escaped unharmed.

A short while later we came upon a tiny bat lying motionless on the pavement. When gently roused it flew up among us and attached itself to a nearby tree.

Central Park North Woods with Ursula Mitra and Kevin Sisco, 5/11/2025

Registrar: Suzanne Zywicki
Participants: 37
Weather
: Sunny, light wind, temperatures ranging from 59-72 degrees
Bird Species: 65

Unlike spring migration walks of years past in Central Park’s North Woods, we had beautiful weather for this May’s field trip. Ursula Mitra and Kevin Sisco capably led a comparatively large group of enthusiastic birders in exploring a part of Central Park that was less familiar than most to many of the participants. Our group was a nice mix of experienced and newer birders, with those possessing stronger birding skills willingly helping others to identify and focus on the birds.

After meeting at 108th and Central Park West, we made our way to the Great Hill, where the morning began with an abundance of warbler sightings, including Blackpoll, Wilson’s, Blackburnian, and Blue-winged, among others. We also viewed several Baltimore Orioles and Scarlet Tanagers in and around the tulip tree.

We then made our way through the jug-handle into the North Woods, where we continued to see warblers in addition to two Yellow-bellied Sapsuckers, a few Rose-Breasted Grosbeaks, and examples of several other species.

Our next stop was the newly opened Davis Center in The Meer, where we were treated to good views of a Black-crowned Night Heron and some Double-Crested Cormorants. After a group lunch at the Green Bench, we explored the compost heap and the nursery, where we saw an Eastern Wood-Peewee, our only flycatcher of the day. We then headed into the Loch, where we had great views of a Canada Warbler near the Glen Span Arch.

We continued on to The Pool, where new birds for the day included two Solitary Sandpipers. Our day ended back on the Great Hill, after almost seven hours of birding! All told, we saw over 20 warbler species and 65 species in total. A big thank you to Ursula and Kevin for sharing their knowledge of the North End and giving us such a fun and rewarding day.

Central Park Spring Migration Walk with Ken Chaya, Richard Davis, Alan Drogin, and Kevin Sisco, 5/6/2025

Registrar: Kathleen Howley
Participants: 25
Weather: Overcast, some rain; 58–63° F
Bird Species: 47


On this Tuesday morning, only half the number of birders who registered for the walk showed up at 7:30 am because the weather report indicated rain within an hour. However, as it turned out, it did not really start raining hard until about 10 am, and by that time we had birded our way to the Castle, which afforded us good protection from the downpour.

The rain stopped by 10:30 am, and we resumed our walk, going along the south side of Turtle Pond. Birds were singing away, especially Yellow-rumped, Black-throated Blue, Magnolia, and Common Yellowthroat Warblers. Overall, it was not easy birding, but no one regretted showing up for the walk.
