Hudson River Almanac

September 13, 2015 - September 18, 2015
Compiled by Tom Lake, Hudson River Estuary Program Naturalist

OVERVIEW

The autumn raptor migration was in full flow along with what seemed to be an increased presence of monarch butterflies. With recent rains and cooler nights, water temperature and salinity in the Hudson Highlands were slowly dropping from summer highs, but some brackish water fishes were still around.

HIGHLIGHT OF THE WEEK

9/16 - Bedford, HRM 35: In the first hour at the Chestnut Ridge Hawkwatch we saw broad-winged hawks rise from the trees and form kettles to the south and east. The next few hours were extremely busy with many healthy kettles passing through. Approximately 1,400 broad-wings were counted in one hour at midday. The total for the day reached 3,361. Non-raptor observations included seven ruby-throated hummingbirds and 48 monarch butterflies.

[“Kettle” is a birding term that describes an aggregation of birds, usually raptors, circling in columns of warm, rising air called thermals. The swirling, upwards movement of birds in the group gives it the appearance of a boiling pot of water with bubbles rising to the top. When the birds reach the top of the thermal, they set their wings and stream off in the direction of migration, often to the bottom of another kettle marking another thermal. There the hawks gain altitude again and stream off to the next kettle. While they can occur almost any time of the year, kettles of broad-winged hawks are particularly prominent during fall migration, as can be seen in this . Steve Stanne.]

NATURAL HISTORY NOTES

9/13 - Catskill to Bear Mountain, HRM 113-46: Across a 67 mile reach of the river from Catskill to Bear Mountain, the Riverkeeper Patrol has been seeing large rafts of duckweed (Lemna sp.). It is fluorescent green, beautiful, and being released from the marshes as water chestnut and other vegetation break loose at the end of the season. Once exposed to tidal current, off the duckweed goes.
- Leah Rae

9/13 - Town of Wappinger, HRM 67: With careful observation it is not difficult to discern that the half-dozen ruby-throated hummingbirds stopping by our feeders now are in migration. The four local birds that spent the summer here (pair and offspring) likely left more than a week ago and are sampling someone else’s feeders to the south. The present birds are a bit more wary, a lot more skittish, and frequently will not settle but rather drink from a hover.
- Tom Lake

9/13 - Bedford, HRM 35: It was a fairly slow day compared to yesterday at the Chestnut Ridge Hawkwatch. We had mostly sharp-shinned hawks (16) with only two broad-winged hawks. The most excitement we had was when an immature red-shouldered hawk was spotted in midday as it flew into the trees with something in its talons. Non-raptor observations included two ruby-throated hummingbirds.
- Charlie Plimpton, Christiana Ricchezza, Tony Wilkinson

9/14 - Selkirk, HRM 135: I noticed that the only visitor to the hummingbird feeder this evening was a lone female. The family and groups of hummingbirds appear to have moved on. While watching the hummer, I counted eighteen wild turkeys in the backyard. I’ve seen this group on several occasions this past month and this time their presence was also noticed by my guinea hens.
- Roberta Jeracka

9/14 - Rhinebeck, HRM 90: A strong and sustained northwest wind signaled the wake of a passing cold front. The midday wind-against-tide produced a raucous river with whitecaps climbing to nearly three feet. An osprey, a northern harrier, and two bald eagles – one immature, one adult – were using the tailwind boost to zoom past, presumably migrating.
- Tom Lake

9/14 - Dutchess County, HRM 82: The leucistic red-tailed hawk we have dubbed “Lucy,” that has been around the Stanfordville-Clinton Corners area for more than three years, was sighted this evening by Carol Pedersen as we left my barn. Lucy was a distant speck in the sky, seemingly flying with a black vulture until we lost sight of her heading north over Jameson Hill.
- Deborah Tracy-Kral

9/14 - Croton Point, RM 35: We searched Croton Point looking for the osprey family of five from the cell tower nest near the Croton train station. The parents and three young were spotted last week in a tree overlooking Eagle Bay on the north side of the Point. The first dead tree we came to held one osprey on a high branch, while another flew nearby. Farther along a third bird was perched on another dead tree. It was nice to see them again since we had monitored their progress in the nest this spring and summer.
- Dorothy Ferguson, Bob Ferguson

9/14 - Bedford, HRM 35: Despite strong winds out of the northwest today at the Chestnut Ridge Hawkwatch, migration was slow. Thirteen sharp-shinned hawks were the high count. Non-raptor observations included six ruby-throated hummingbirds.
- Charlie Plimpton, Allen Kurtz, Christiana Ricchezza, Jack Kozuchowski, Jan Linskey, Pat Linskey, Wes MacKenzie

9/14 - Bronx, HRM 14: Within seven minutes of each other, I saw two sharp-shinned hawks winging their way along the eastern bank of the Hudson just north of Spuyten Duyvil, where the Harlem River meets the Hudson. Each was carrying a small bird in its talons. Shortly thereafter, I watched as seven more sharp-shins circled and soared on thermals above the river.
- Jennifer Scarlott

9/14 - Inwood Hill Park, HRM 13.5: Columbia University created a little marsh adjacent to the park with areas of salt marsh, freshwater marsh, and damp meadow. Spartina [salt meadow cordgrass] was thriving along with grasses that grow in drier places. Goldenrods and New England aster were blooming. Elsewhere along the water, flowers of yam-leaved clematis were suddenly profuse. There, as well as up in the woods, common dayflower was having an abundant second flowering; the flowers were small and low down, but very beautiful. On the path up The Clove jewelweed was now in full flower but not as abundant as in recent years. The woods generally seem tired, as if this summer’s combination of heat and lack of rainfall hadn’t been ideal. The asters that bloomed up there seemed almost finished, while white snakeroot, which usually blooms at the same time, was just budding, and goldenrods were noticeably absent.

cedar waxwing9/15 - Town of Knox, HRM 143: In the 46 years we have lived in Knox, we had not seen cedar waxwings on any of our ponds. This year we have had the pleasure of watching dozens of them harvesting the various insects and small dragonflies from the surface of our one-third-acre pond. It has been an amazing sight as they seemed to effortlessly fly over the pond for hours at a time without resting.

9/15 - Warwick, HRM 41: For the past few days I have been a visitor at the Mount Peter Hawk Watch in Warwick. In addition to more than four thousand broad-winged hawks, we have had a dozen bald eagles. We have noticed pairs often traveling together with one continuing south, the other returning north. Is one eagle an escort (get out of my territory)? We wonder how many of these birds have traveled a great distance and if any are “locals.”
- Amy Greher

9/15 - Bedford, HRM 35: There was a nice flow of broad-winged hawks (226) throughout the day at the Chestnut Ridge Hawkwatch. Most were seen very high directly above the watch. Other highlights include an adult bald eagle that flew right over the platform. Non-raptor observations included seven ruby-throated hummingbirds, two common ravens, and five monarch butterflies.
- Charlie Plimpton, Allen Kurtz, Christiana Ricchezza, Ray Ferrara, Wes MacKenzie

9/16 - Saratoga County, HRM 164.5: This was Day 54 for the wayward harbor seal above tidewater, and there have been no sightings in nearly two weeks. I think the seal probably just moved its home base (it has been Lock One of the Hudson-Champlain Canal) as it seemed to be doing alright for itself. I have visions of the seal being “MIA” for a while, and then suddenly appearing this autumn. This is a plucky little animal.
- Shannon Fitzgerald

9/16 - Haverstraw Bay, HRM 36: We were sailing along on our 22 footer, going about seven to eight knots, with little wave action, on a starboard tack. We timed our glance perfectly to see an eighteen-inch fish breach the water and “fly” along parallel to the gunnel only six inches away. Even in the short time we saw it, the fish was unmistakable: It was a small sturgeon. If we had been on the port tack it would have landed in the boat. The knot meter on our sailboat read 3.9 km/hr. which must have been the speed at which it cleared the water.
- Mary Ann Boothe, Bob Boothe

9/17 - Hyde Park, HRM 82: About twenty minutes after sunset, I counted four small bats (little brown myotis) flitting about, up and down our wooded road. This is fewer than in previous years when I've counted up to seven at a time, but it's more than this year's average of one to two, and likely the most I've seen at one time this summer. They all seemed to be catching insects quite successfully.
- Dave Lindemann

9/17 - Poughkeepsie, HRM 75: We were in our yard in mid-morning when we heard and saw a pair of hawks calling. At first we thought they were red-tails, the most common hawk in our neighborhood. However, the calls didn't seem right; instead we saw the diagnostic characteristic features of red-shouldered hawks - probably a pair in migration.
- Maury Lacher, Miriam Lacher

9/17 - Kowawese, HRM 59: Dawn was rising over the Hudson Highlands as we set our seine in the shallows. The river had cooled off to 75 degrees Fahrenheit and gotten a bit less salty at 4.0 parts per thousand [ppt]. Bluefish and silversides were missing but in their place was another brackish-water marker: young-of-the-year [YOY] Atlantic menhaden or “penny bunker” 71-81 millimeters [mm] long. We caught two different year-classes of smallmouth bass (75-175 mm), probable emigres from Moodna Creek, a quarter-mile down river, and too many YOY blueback herring (60-68 mm) to count (hundreds).
- Tom Lake, A. Danforth

young-of-the-year Atlantic menhaden[Atlantic menhaden are a species of herring that spawn in salt to brackish water. Adults, also known regionally as bunker, mossbunker, or pogies, and their young-of-the-year, known colloquially as penny bunker or peanut bunker, are found by the millions in the estuary in summer, providing forage for striped bass, bluefish, harriers, osprey, eagles and seals.

9/17 - Garrison, HRM 51: As our tour boat approached Mystery Point in Garrison, a magnificent adult bald eagle appeared seemingly out of nowhere and plucked a fish from the Hudson. The eagle was gone in a flash, white tail gleaming in the sunlight, as it retreated to the wooded shoreline to enjoy its catch.
- Dianne Picciano

9/17 - Croton-on-Hudson, HRM 35: Hummingbirds continued to flock to the feeder and this morning I had a special treat. As I watered my garden, one flew up to me and hovered around my head for close to a minute, close enough that I could feel the breeze from its wings on my face and shoulders. A beautiful feeling.
- Jim Miller

9/17 - Bedford, HRM 35: It was a surprisingly quiet day at the Chestnut Ridge Hawkwatch considering yesterday’s activity. Very few broad-winged hawks (23) were around but we had a surge of sharp-shinned hawks (42) in the last two hours. Non-raptor observations included ten ruby-throated hummingbirds, twenty-two monarch butterflies, and two common ravens.

9/17 - Croton River, HRM 34: I began my day being buzzed by hummingbirds on my deck and finished the day with a kayak paddle at dusk on the Croton River under a setting crescent moon. Fish were rising all over and the “fish eaters” were on notice. A classic tale retold: An osprey dove and caught a fish; as it rose there was a flash of white in the trees - the tail of a bald eagle; it chased, harassed and caught the fish released by the osprey in mid-air. As the adult eagle flew upriver, a juvenile flew out of the trees and followed. I later encountered the juvenile in the shadows on a gravel bank devouring a fish. As I returned down river, I saw the two eagles twice more as they scouted the river from trees and shore. Also joining in the moving buffet were many great blue herons, cormorants, and kingfishers.
- Jim Miller

9/18 - Minerva, HRM 284: Our leaves were only vaguely colored here in Essex County. A little frost would be a good thing. Blue asters and boneset were blooming nicely, and winterberry hollies were loaded with red berries.
- Mike Corey

9/18 - Bedford, HRM 35: Broad-winged hawks were moving today at the Chestnut Ridge Hawkwatch, but a south wind kept them away from us. Broad-winged totals for the season had reached 3,724. Highlights of the day were an adult and an immature bald eagle in midday. Non-raptor observations included three ruby-throated hummingbirds and six monarch butterflies.
- Charlie Plimpton

male American redstart9/18 - Manhattan, HRM 3.5: There is a particular corner in Bryant Park, in midtown Manhattan at 42nd Street, near my office, that has a bird bath and begonias where I sometimes see common yellowthroats. Today I went there during lunch and was stunned to see a male American redstart walking among the flowers. There were also an ovenbird and several female yellowthroats. Just as I spotted the redstart, someone standing nearby carrying binoculars saw the bird as well. We were both surprised to see a redstart in Bryant Park; neither of us had seen one there before. Nice birding in Manhattan. [Photo of American redstart courtesy of Deborah Tracy-Kral.] - Caroline McDonald

HUDSON RIVER MILES

The Hudson is measured north from Hudson River Mile 0 at the Battery at the southern tip of Manhattan. The George Washington Bridge is at HRM 12, the Tappan Zee 28, Bear Mountain 47, Beacon-Newburgh 62, Mid-Hudson 75, Kingston-Rhinecliff 95, Rip Van Winkle 114, and the Federal Dam at Troy, the head of tidewater, at 153. The tidal section of the Hudson constitutes a bit less than half the total distance – 315 miles – from Lake Tear of the Clouds to the Battery. Entries from points east and west in the watershed reference the corresponding river mile on the mainstem.

NY Open for Hunting and Fishing Initiative
Governor Cuomo's NY Open for Fishing and Hunting Initiative is an effort to improve recreational opportunities for sportsmen and women and to boost tourism activities throughout the state. This initiative includes streamlining fishing and hunting licenses, reducing license fees, improving access for fishing and increasing hunting opportunities in New York State.
In support of this initiative, this year's budget includes $6 million in NY Works funding to support creating 50 new land and water access projects to connect hunters, anglers, bird watchers and others who enjoy the outdoors to more than 380,000 acres of existing state and easement lands that have gone largely untapped until now. These 50 new access projects include building new boat launches, installing new hunting blinds and building new trails and parking areas. In addition, the 2014-15 budget includes $4 million to repair the state's fish hatcheries; and renews and allows expanded use of crossbows for hunting in New York State.
This year's budget also reduces short-term fishing licenses fees; increases the number of authorized statewide free fishing days to eight from two; authorizes DEC to offer 10 days of promotional prices for hunting, fishing and trapping licenses; and authorizes free Adventure Plates for new lifetime license holders, discounted Adventure Plates for existing lifetime license holders and regular fee Adventure Plates for annual license holders.
