Jack-In-The-Pulpit – An Unusual Wildflower

The Jack-in-the-pulpit (Arisaema triphyllum) is a spring wildflower of moist woodlands and may be encountered in oak-hickory forests and forested swamps. Though some consider this member of the Arum family a single species with several variations, others believe there to be three separate species of Jack-in-the-pulpit. 
This interesting plant flowers from April to June, but unless you look closely you will not see the actual flowers. What you will see is a green or purple striped spathe (pulpit) encircling and curving over a club-shaped spadix (Jack). Tiny flowers are found within the pulpit at the base of the spadix. All well and good, you say, but how do pollinators find the blossoms?

Like other members of the Arum family, such as skunk cabbage, the Jack-in-the-pulpit is believed to give off a fetid odor. Consequently, small flies in search of a rotting carcass on which to lay their eggs are attracted to the plant’s unobtrusive flowers. When the flies enter the spathe they brush against its pollen and carry it to other Jacks. 
The one or two leaves of this wildflower are divided into three leaflets that top long stalks. Impressive varieties can grow to three feet tall, though most you find will be less than a foot high. Once you learn to recognize its leaves, the Jack-in-the-pulpit hiding beneath will become easy to spot.

In late summer a bright cluster of red berries forms on a thickened stalk. Wood thrush and wild turkeys will eat these woodland fruits. Native Americans were known to consume the tuberous roots of the Jack-in-the-pulpit, which gives the plant another common name – Indian turnip. Since the roots contain calcium oxalate crystals and would cause a severe burning sensation if eaten raw, they were cooked thoroughly before being eaten.

The Atlantic Flyway - Long Island Sound

Preserving And Restoring Long Island Sound is an important part of Audubon’s Saving Important Bird Areas conservation strategy for the Atlantic Flyway.
Species: Saltmarsh Sparrow, Roseate Tern, Piping Plover, and other shorebirds
Habitat: Long Island Sound 
Our Work: Roughly 10 percent of the U.S. population lives within 50 miles of Long Island Sound. A vital resource for birds and people alike, this rich estuary faces intense development pressure and recreational and commercial demands. Audubon is leading an ambitious effort to improve water quality, restore vital habitats, and promote biodiversity.
Conservation Impact: National Audubon policy staff joined forces with Audubon Connecticut and Audubon New York to rally federal, state, and local lawmakers as well as other stakeholders to endorse Sound Vision, a two-year action plan to protect and restore the Sound. Developed by the Long Island Sound Citizens Advisory Committee, the plan combines new and existing restoration projects with uniļ¬ed legislative efforts. Science plays a key role in Audubon’s work to protect and restore the Sound.
Conservation Outlook: Audubon national and state staff, Chapters, activists, and volunteers will continue working to reduce pollution and protect and restore habitat in this vital ecosystem.

Film Screenings: A Fierce Green Fire, A Last Call at the Oasis: Water

A Fierce Green Fire
Sunday, May 12, 2:00-3:30 p.m.
Blackstone Memorial Library, Branford

A Fierce Green Fire: The Battle for a Living Planet is the first big-picture exploration of the environmental movement – grassroots and global activism spanning fifty years from conservation to climate change. 
Inspired by the book of the same name by Philip Shabecoff and informed by advisors like the biologist E.O. Wilson, A Fierce Green Fire chronicles the largest movement of the 20th century and one of the keys to the 21st. It brings together all the major parts of environmentalism and connects them. It focuses on activism, people fighting to save their homes, their lives, the future – and succeeding against all odds.


The film unfolds in five acts, each with a central story and character:
  • David Brower and the Sierra Club’s battle to halt dams in the Grand Canyon
  • Lois Gibbs and the Love Canal residents’ struggle against 20,000 tons of toxic chemicals
  • Paul Watson and Greenpeace’s campaigns to save whales and baby harp seals
  • Chico Mendes and Brazilian rubbertappers’ fight to save the Amazon rainforest
  • Bill McKibben and the 25-year effort to address the impossible issue – climate change
The film arrives at a moment of promise: 25 years after Dr. James Hansen first warned of global warming; 8 years after Katrina; 3 years after the Gulf oil disaster; 2 years after meltdown at Fukushima; a year and a half since stopping the Keystone Pipeline; and half a year since the wakeup call that was Hurricane Sandy, the capper to the hottest year on record. A Fierce Green Fire tells stories about four successful movements, then takes up the biggest cause of all, still in suspense. It gives us reason to believe change can come.

A Last Call at the Oasis: Water
Saturday, June 22, 2:00-3:30 p.m.
Blackstone Memorial Library, Branford

Water. It’s the earth’s most valuable resource. Our cities are powered by it, countless industries depend on it, and all living things need it to survive. But it’s very possible that in the near future, there won’t be enough to sustain life on our planet.


The global water crisis will be the central issue facing our world this century. We can manage this problem, but only if we are willing to act now. Last Call at the Oasis is a powerful new documentary that shatters myths behind our most precious resource. This film exposes defects in the current system, shows communities already struggling with its ill-effects and highlights individuals championing revolutionary solutions during the global water crisis. Firmly establishing the global water crisis as the central issue facing our world this century, the film posits that we can manage this problem if we act now.

The film series is cosponsored by Audubon Connecticut.

Citizen Science: Hummingbirds at Home

Hummingbirds at Home – Audubon’s New Citizen Science Project

Hummingbirds visit our yards each spring to breed, looking for nectar from our gardens and feeders. Fascinating to watch, hummingbirds captivate us with their magical feats of flight and their showy colors. The Continental US is breeding home to 14 species of hummingbirds, with a few other species making rare appearances. 
Recent science reports that flowers are blooming earlier and earlier due to climate change. Some flowers are blooming as many as 17 days before the migrating hummingbirds arrive. The impact for migrating and breeding hummingbirds is unknown. 
Building on our Christmas Bird Count (CBC) legacy and the more recent success of the Great Backyard Bird Count (GBBC), Audubon is launching a new program called Hummingbirds at Home.

Through this new program Audubon’s goal is to gather data that will help document the hummingbirds’ journey, and better understand how changing flowering patterns and supplemental feeding by people relate to hummingbirds’ migration and breeding success, and also climate change. Since nectar is critical to hummingbirds, we’re asking people to document which flowering plants hummingbirds are feeding on in their backyards as well as whether hummingbird feeders are supplied and used. The Hummingbirds at Home program will provide an opportunity for citizen scientists to help us learn how these changes in the environment are impacting hummingbirds. 
In this family-friendly program, participants will log hummingbird sightings and the flowering plants or feeders they visit, with free mobile technology or on desktop computers. Participants can also view hummingbird sightings online in real time. Scientists will use the data to better understand how hummingbirds are impacted by feeders, non-native nectar sources in gardens, shifting flowering times, and climate change. 



Do you enjoy watching hummingbirds and want to become involved in this program? You can participate at a level that fits your schedule – from one sighting to watching hummingbirds over several weekends throughout the program.

Menunkatuck and SEANET Will be Partnering for Beached Bird Surveys

Menunkatuck Audubon Society will be partnering with SEANET in organizing volunteers for beached bird surveys along the Connecticut shore from Madison to West Haven. 
The Seabird Ecological Assessment Network (SEANET) is a citizen science program that brings together interdisciplinary researchers and members of the public in a long-term collaborative effort to identify and mitigate threats to marine birds.
SEANET was initiated by the Tufts Center for Conservation Medicine, in collaboration with the Lloyd Center for Environmental Studies in Massachusetts, during Autumn 2002. Since this time, the project has expanded to beaches throughout New England, New York, New Jersey, South Carolina, Georgia, and Florida. 
SEANET volunteers conduct year-round beached bird surveys in order to identify and record information about bird mortality along the east coast of the United States. Data collected by hundreds of SEANET volunteers are used to examine the spatial pattern of bird carcass deposition and how it varies across time.
These surveys provide baseline information about bird mortality and can help to detect mass mortality events due to oil spills, algal toxins, and disease outbreaks. Marine birds can serve as indicators of ecosystem and human health; monitoring the threats they face and their mortality patterns can teach us about the health of the marine environment.

Amy Hopkins and Dennis Riordan have identified about 27 beaches in the Chapter area that could be surveyed, fifteen that meet the SEANET protocol of being one kilometer long and another 12 that could be combined in pairs to make about 1 km. We are now looking for people who are interested in participating in the SEANET surveys. SEANET volunteers must conduct surveys at least twice every month, close to two weeks apart. If you are only able to walk once a month, but still want to participate, we will pair you up with another volunteer so that you will generate twice monthly walks between you. If you are interested in becoming a SEANET volunteer, go to goo.gl/HI2Nw and complete the form.
Even if you aren’t a Seanetter, SEANET wants your information should you come across a SEANET tagged bird. The volunteers place orange cable ties on the wings, legs and beaks of the birds they find. Many of the volunteers also affix individually numbered aluminum tags. If you find a bird that you suspect was tagged as part of the project, please don’t disturb, move or throw it away! SEANET collects data on how long dead birds stay on the beach, and whether they move up and down
the coast with the tides. If you find a SEANET bird, please leave it where it is, snap a photo if you can, note the tag number (if present) and send the info along to Sarah Courchesne via email (sarah.courchesne@tufts.edu).
