YELLOW-RUMPED WARBLERS EATING POISON IVY

Leave a reply

All around Cape Ann, from West Gloucester to East, from Cape Hedge to Good Harbor to Cox Reservation, I have been checking out the Poison Ivy patches and sure enough, there are Yellow-rumped Warblers relishing the white waxy fruits at every locale. Who knew it was a thing 🙂 And now I have a new favorite species to add to the long list of beloved wild creatures.

According to Cornell, Yellow-rumped Warblers are the only warbler able to digest the waxes found in Wax Myrtle and Bayberries. This ability to digest waxy fruit allows the Yellow-rumped Warbler to winter as far north as Newfoundland.

Yellow -rumped warblers are versatile foragers. They eat insects in the spring, summer, and when available. You may see them picking at insects on washed up seaweed. During migration and the winter months, their habit is to eat Poison Ivy fruits, grapes, Wax Myrtle, Bayberries, Virginia Creeper berries, dogwood fruits, and Juniper berries. Yellow-rumped Warblers also eat goldenrod seeds and beach grass seed, and if you are fortunate to have them at your feeder, provide Sunflowers seeds, raisins, peanut butter, and suet.

The Yellow-rumped Warblers have been dining on PI fruits for over a month. As autumn has unfolded, I’ve added new clips to the short film below. Filmed from mid-September to mid-October I see no signs of the feast abating as there is still plenty of fruit around. More photos to come when I have time to sort though.

See a story form March of this year, Yellow-rumped Warblers in the Snow.

LEAVES OF THREE, LET IT BE

1 Reply

In thinking about our community’s efforts to Save Salt Island from deforestation and development, I wanted to share evidence that the vines and shrubs on the island are an important source of food for a host of small mammals and birds.

One of the most reviled of plants, Poison Ivy, is an excellent food plant for wildlife and will not cause the itchy uncomfortable rash if you do not touch the leaves, stems, fruits, and roots. Poison Ivy can either look like a shrub or a vine. Regardless of the shape, the leaves are easily identifiable in that they are always arranged in three; two leaves opposite one another, and between them the third leaf is borne on a stem growing at a right angle from the two shorter leaves.

Common Bonnet Fungi and Poison Ivy

Out on Eastern Point there are large patches of Poison Ivy that grow smack on the edge of very well traveled pathways. They have grown that way for decades, yet no one bothers the Poison Ivy and the Poison Ivy bothers no one. The spring blooming greenish yellow clusters of flowers are beloved by bees and myriad pollinators, while the vitamin rich white waxy berries are relished by resident and migrating songbirds alike.

In autumn, the plant’s glossy green leaves turn a brilliant red, which acts as a “red flag” to hungry songbirds. The long list of birds that dine on Poison Ivy fruits include Yellow-rumped Warblers, Eastern Bluebirds, Downy Woodpeckers, Northern Mockingbirds, Song Sparrows, Gray Catbirds, Bobwhites, and many, many more.

Poison Ivy Tips – If you come in contact, rinse the area with cold water, not soap, as soon after contact as possible. Ocean water works well when near to the beach. If you have Jewelweed growing handily nearby, smear the juice of the stem on the exposed skin. Never burn Poison Ivy. With burning,  urushiol (the poisonous oil in Poison Ivy) becomes volatilized in the smoke and you can get it in your lungs, which is very dangerous and can even lead to death.

#savesaltisland CONSERVATION MEETING POSTPONED ONCE AGAIN

Save Salt Island Friends Jayne and Andy write,

Hello protectors of Salt Island,

The agenda for the Conservation Commission meeting tonight, Wednesday April 20th, has been updated and the proponents of RDA-1703 Salt Island have requested a continuance to May 4, 2022.  The administrative record for this application has also been moved from April 20, 2022 to May 4, 2022.

Andy and I are still planning to attend to observe the vote of the request for continuation, but based on all of the past meetings, it will likely pass.  We are letting you know since your time is valuable and it would be unfortunate to have you attend unnecessarily.  Of course, if you still want to attend… GREAT!  We will continue to watch for any changes to the application between now and May 5th.

Thank you again for your patience and perseverance.

Warm regards,

Jayne and Andy

EVERYONE’S HELP IS NEEDED TO SAVE SALT ISLAND FROM DEVELOPMENT AND FROM GOAT INVASION!!! YOU CAN TAKE ACTION!

Leave a reply

The entire community’s help is needed. Salt Island is one of Gloucester’s most beautiful natural treasures and a vibrant part of our coastal ecosystem. Martignetti’s proposed future dream house for Salt Island

Why goats are a terrible idea for a coastal ecosystem

Goats used to control vegetation in places like Central Park and cemeteries have had some success however, these locations are not fragile coastal ecosystems. Goats are not discriminating and will eat everything in their path. To eradicate PI, you must dig it up by the roots.

Salt Island is an oasis of native plants and shrubs. Natural, largely undisturbed habitats, like Salt Island, provide refuge and food for resident and migrating birds alike.  Note in the photo below, which was taken at the time of installing the fence posts, the beautiful native vegetation growing at the Island.

We need to point out that the fallacy stated by Mr. Matignetti at the Conservation Committee meeting,”Poison Ivy is an invasive species,”  is incorrect. Poison Ivy is a native North America plant and is known for its value to wildlife. Poison Ivy flowers bloom early in the spring, providing nectar to myraid species of bees and other pollinators. The fruit of Poison Ivy is consumed by dozens and dozens of songbird species. The berries provide much needed sustenance in the late summer, fall, and winter. These are just some of the birds that eat PI fruits: Northern Flicker, Bobwhite. Quail, Eastern Phoebe, Cedar Waxwing, woodpeckers, Tufted Titmouse, and American Robin.

Granted, Poison Ivy is not a plant you want to become entangled with but the entire Island does not need the vegetation eradicated under the guise of removing PI. 

There are shorebirds, ducks, and gulls nesting at Salt Island, along with a highly productive shellfish bed. Lobsters are caught off the shores of Salt Island and baby lobsters need fresh, uncontaminated water. We do not want goat feces and goat worms contaminating this vibrant coastal ecosystem!

Typical fencing used for goat vegetation control is three feet tall livestock fencing-

unlike the fence posts that have been installed at Salt Island, which are permanently bolted into the granite rocks.Fence posts permanently bolted to the granite at Salt Island

Notice how far the fence posts go down on the left. This is not a “keep in the goats” fence line, but a “keep out the people fence line.”

ACTIONS YOU CAN TAKE:

Please email our City Councilors. We learned that when trying to change the dog ordinance to protect Piping Plovers that the more people that write to the Councilors, the better chance our voices will be heard. There is power in numbers. Please write in your own words, or copy paste the following –

Dear Councilor,

Please help us save Salt Island from future development, goats, and all destructive and detrimental activities to this vibrant coastal ecosystem. Thank you.

Attend the virtual Conservation Committee meeting on Wednesday evening at 6pm.

Oh how pretty! Doesn’t this bucolic scene look interesting? I had to stop and take a photo. And then began to walk toward, wanting a closer look, before catching myself. If poison ivy even looks at me, or I look at it, that most unpleasant of itchy rashes finds a home on my person.

Poison ivy is in full glorious color right now, dissipating in shades of golden yellow, tangerine, and crimson scarlet. The oils found in the foliage and stems are just as potent at this time of year as they are during the summer months.

Berries white, run in fright,

Red hairy vine, no friend of mine!

Cape Ann shores and meadows are rife with poison ivy and the best defense is to recognize the leaves and wear protective clothing. Not a plant one desires for the home garden, it is an important bee and bird food. The flowers provide nectar for pollinators in the spring and the small white berries are a winter staple for our some of our most beloved songbirds, including American Robins, Northern Cardinals, and Mockingbirds.

The Dreadfully Despicable and Despised Poison Ivy (and Why I Think it Beautiful)

Perhaps the most disliked plant of all is poison ivy, despised throughout its range for the blistering rash that oozes and itches when one has the misfortune to come in contact with any part of the plant. What is the substance that causes that most dreaded of unpleasant of rashes? Poison ivy is infused with usushiol, a compound that not only wards off humans, but caterpillars, too (generally speaking, caterpillars are a plant’s number one enemy).


Toxicodendron_radicans_01Poison Ivy in Flower

Several of my landscape design projects are located on Plum Island. I laughed initially when it was first brought to my attention that poison ivy was one of the “approved” plants permitted on Plum Island. Of course, whether approved or not, I wouldn’t dream of planting poison ivy on a client’s property, but I did want to learn more about why it was on the approved list. And here’s the reason why we might want to rethink our dislike towards poison ivy: Plum Island is home to and breeding ground for hundreds of bird species and small animals. The blossoms of poison ivy are a rich nectar source for many pollinators, and the berries are a prime winter staple for dozens and dozens of song birds, including cardinals, mockingbirds, and robins.

Malign poison ivy if you will for its dreadful rash and clamoring habit. Lets rip it out of our backyard play spaces and public pathways. But knowing it holds an important place in our ecosystem, lets allow it to continue to grow wild in wild and appropriate places. Poison ivy is one of the essential reasons why we are privy to the legions and legions of beautiful birds that dwell, nest, and migrate through our region.

Yellow-rumped warblers are able to withstand our cold winters by switching from a diet of primarily insects, to one of poison ivy berries, bayberry, and other small fruits.

1024px-Poison_ivy_vine“Red hairy vine, no friend of mine!”

The telltale reddish hairs of the vine are clearly evident in the above image; leaves, vines, stems, and hairs are all toxic to humans. As I am constantly exposed to poison ivy due to landscape design projects, and oftentimes filming and photographing in locations where poison ivy is prevalent, my number one solution to avoiding contact is to identify its presence and to wear protective clothing. Knowing poison ivy’s mnemonic rhymes will help with its identification: “Leaves of three, let it be!”, “Berries white, run in fright!”, and “Red hairy vine, no friend of mine!”
