Thursday, May 23, 7:00 pm Restoring Croton Point Grassland Croton Free Library
Using state funding to its Soil and Water Conservation District, the County of Westchester is restoring valuable grassland atop the former landfill at Croton Point Park. Larry Weaner Landscape Associates is designing the project, which is intended to curb less desirable, invasive plants in favor of more ecologically friendly native plants to improve wildlife habitat, especially for birds. Come hear how the grassland restoration plan was developed and the timeline for this exciting and innovative project. Presenters will be Larry Weaner and Jenna Webster from Larry Weaner Landscape Associates.

Saw Mill River Audubon connects you with free, intriguing and engaging evening programs every month between September and June. We offer our programs at different locations across our membership area. Here is our line up of programs for Fall 2018.
In late March 2017, Charlie Roberto noted that he had seen Purple Martins last spring just a few miles north of Croton Point, in Putnam County along the Hudson. He added, “Croton Point is a perfect place for a colony…but we would have to get it done by the end of April to have a chance for nesting this year.” Challenge accepted!
Saw Mill River Audubon contacted Rob Armanini, owner of the Feed the Birds store in Croton to see about martin tower pricing. Rob immediately offered us wholesale pricing and then went even further than that, underwriting half the cost. (Thanks again, Rob!)
SMRA also contacted John Baker, (then) Director of Conservation for Westchester County Parks, who linked us with the Westchester Parks Foundation for more funding support.
Croton Point Park Naturalist John Phillips handled the Croton Point Park permissions and went even further, arranging for some park staff to dig the hole, and erect the tower. Meanwhile, John also assembled the many, many parts that go into a purple martin nesting tower.
By April 19, Croton Point Park had a brand new Purple Martin nesting tower. Now for some martins.
There’s a wealth of advice online about Purple Martin colonies including an active discussion forum at the Purple Martin Conservation Association’s web site (www.purplemartin.org.) All these experienced martin watchers agree that the best way to attract martins to a new colony was (1) have a purple martin plastic decoy at the top of the tower, and (2) play recordings of a purple martin dawn song — when else? — at dawn. Purple Martins are highly social and will show up where they think other martins already are.
Fake Martin
John Phillips took care of getting the plastic Purple Martin decoy installed. This plastic decoy came with our Purple Martin structure but lacked a good attachment scheme. No matter. Some duct tape did the trick. (We shall leave nameless those few birders that, briefly, eBirded the plastic martin.)
As for the dawn songs, there’s an .mp3 audio file for that. We put up a notice on Facebook for some volunteers to come at dawn and play recordings. Jessica T. stepped up for several mornings of song playing, some others did as well. We persisted. And a month went by with no Purple Martins.
May 22, 2017 Saw Mill River Audubon’s regular 4th Monday morning walk at Croton Point saw a martin! A lone Purple Martin — perhaps a scout for a new colony — was flying around the main parking lot, singing and trying to enter the emergency siren structure. Just down the road from our sparkling new nesting structure.
This one martin stuck around for two more weeks, finally making its way over the nesting tower.
It kept adding its voice to our dawn chorus playbacks and then, at last, FOUR Purple Martins were seen on June 8, sitting and singing in the right place, on the new nesting tower.
A week later, June 15, we had five martins and a week later, reports of up to 8 martins! .
Our Monday walk on June 26 stopped to watch the martins. We saw an adult pair, male and female, carrying nesting materials into one of the nesting gourds.
If nesting is successful, this will be the only known Purple Martin colony in Westchester County. (A small colony was in the Rye area, along the Long Island Sound, but apparently lost its housing during Hurricane Sandy in 2012.)
Here’s another look at real Purple Martins on the tower either side of the decoy martin.

August 2017 Update
Despite several people observing the nesting tower, we are uncertain whether nesting was successful this year and we will check the nesting gourds before winter storage. However, by the middle of August, as many as 11 martins were seen at once, as shown in this photo below by Jim Bourdon. (The Martin decoy was also slipping its duct tape bounds at that point and later retrieved to be reattached next spring.)
September 2017 Update: What was in the Gourds?
Croton Point Naturalist John Phillips took down the nesting gourds the end of September and cleaned them out. He also recorded the contents of the gourds and noted, “The uniformity of the contents of 6 of the 8 gourds is remarkable.”
Bottom line: we don’t think we had nesting Purple Martins this year but are hoping for next year! See John’s notes below
Gourd contents:
1N (lower, facing gate house)
– clean no droppings
– 1 twig tip White Pine
– 6 stems/leaves/seed heads of various grasses
– 1 phragmites stem section
2N (upper, facing gate house)
– clean (1 dropping)
– 1 White Pine needle whorl
– 5 stems/leaves/seed heads of various grasses)
– 1 Phragmites outer stem
– 1small white feather
1E (lower, facing Park entrance)
– light droppings and debris
– 1 White Pine twig
– 15 stems/leaves/seed heads various grasses, 3-4 different species
– 4 small white feathers
– 2 large feathers, one white, one dark
– 1 strip Phragmites core, one sm rectangle Phrag outer stem
2E (upper, facing Park entrance)
– significant nesting materials but fairly clean- apparently unused
– a few droppings
– bottom 1/3 of gourd full of various grasses (# sp.?)
– a few small stems Phragmites, one ribbon Phrag cambium
– a few White Pine twigs
– approx 30 feathers, mostly small white, mixed in with grasses
– 2 sm pieces plastic
– in lower layer (buried) a fully formed nesting cup made of various grasses and lined with large number of feathers. *
1S (lower, facing Maintenance Barn)
– trace droppings
– 8 grass stems/leaves/seed heads various species
– 1 ribbon Phrag cambium
– small paper wasp nest below entrance platform (interior)
2S (upper, facing Maintenance Barn)
– clean
– 10 grass stems/leaves/seed heads
– 1 small gray feather
1W (lower, facing bath house)
– Apparently remains of nesting activity. Different contents than all other gourds: compacted mass apparently cemented by droppings.
– shallow, solid, dark mass on bottom 3″ of gourd. Difficult to remove.
– a few large loose twigs, feathers, and a few identifiable droppings on top of mass
– mass composed primarily of thousands of insect exoskeletons w iridescent blue and green fragments, a few intact thorax, abdomens, legs. One apparent Cicada wing, one apparent dragonfly wing.
– Also fragments of brown deciduous leaves (oak? maple?) 6 valves and one whole bivalve Asian Clam (Corbicula),
– a few partial feathers, pieces Phragmites stems & cambium ribbon, hatched fly eggs (sp?),
– at bottom of mass many pieces of flat plastic (candy wrappers, cellophane, sheet plastic, etc.)
2W (upper facing bath house)
– clean
– 5 White Pine needles (2 loose, 3 remaining in original whorl)
– 20 grass stems/leaves/seedheads, various species
– 2 small white feathers (down)
– 1 section Phragmites stem
Karalyn Lamb was able to identify some of the grasses as “non-native cool season grasses” and “switch grasses”.
* Jim Bourdon suggested that 2E may have held a Tree Swallow nest early on in June (which was subsequently covered over by the Martins?)
Spring 2018 Update
Max count of five Martins — three adult males among them — are being seen around the nesting structure as of May 18, 2018 with one pair, at least, apparently establishing a nest in one gourd.
This past year saw strong participation in our events, with over 100 well-attended field trips and dozens of classroom and community programs. The 2016 annual fund drive was our strongest ever. More

Hudson River EagleFest!
SMRA is proud to be part of the 8th annual Hudson River EagleFest centered at Croton Point Park on Saturday, February 11 from 9:00 am to 4:00 pm (The snow date is Sunday, February 12.)
For the past decade, Teatown Lake Reservation has been the prime mover behind this event which celebrates the return of our national bird, the Bald Eagle, to the Hudson Valley. SMRA does our part at EagleFest by leading bird walks inside Croton Point, offering our “Raptors for Rookies” program at Croton Point, providing birders with spotting scopes at the Croton boat ramp and George’s Island to help spot eagles and other birds, and underwriting the cost of warming tents at both locations. SMRA Board Member Larry Trachtenberg, donated the cost of the warming tent at George’s Island. (Thank you, Larry!)
The festival will also feature live birds of prey shows, two screenings of the film Eagle Huntress at Pace University and music by Tom Chapin and other artists. There are even guided bus tours to visit all the key eagle viewing spots. Please note that some special events do require advance reservations before the event.
There is an EagleFest admission charge to enter Croton Point Park for the main event tent and other activities there. To find out more and make advance special event reservations, visit: www.teatown.org/eaglefest-schedule
