Marian’s Wildlife Blog for September 2018

Osprey – Doug Pederson

August and September are bird migration months, and we are sad to see them go. Most of our hawks leave us mid-September when wind conditions are right, as do our hummingbirds, warblers and many others. Sometimes we wish that we could follow along as they make the journey, and now we can.

In 2013, Judy Shamoun-Baranes, a Dutch ecologist at the University of Amsterdam developed a radar tool which makes it possible to visualize bird migrations. Her team developed a visualization program in Europe and also one in the United States. Many birds migrate at night so they are very difficult to track without radar. Shamoun-Baranes used data from thirteen weather radars in the Northeast during the fall of 2010. Blue streaks show the movements of many birds together. The tools show direction, altitude, speed and the different routes birds chose on different days. Depending on weather and winds, birds may choose a southwestern route or an eastern route out over the Atlantic Ocean. read more….

The tools show direction, altitude, speed and the different routes birds chose on different days. Depending on weather and winds, birds may choose a southwestern route or an eastern route out over the Atlantic Ocean. Different bird species may favor a certain route and wait for the proper winds. Seeing these maps is more than just entertaining. Studying the routes birds take can help pilots avoid strikes and help researchers understand the choices birds make in their routes. You can take a look at one of these maps here: http://timamp.github.io/timamp/v2/case-us.html. You can see Judy Shamoun-Barnes giving an interesting Ted Talk on bird migration on UTube, August, 2016.

One of our champion migrators is the blackpoll warbler. Each fall these tiny birds leave New England and eastern Canada and fly across open water as far south as Argentina. In 2013 and 2014, a UMass Amherst research team led by William DeLuca outfitted thirty-seven blackpoll warblers with geolocators and found that the warblers complete a journey of up to 1721 miles without stops. De Luca states that even though it had long been suspected that blackpolls took this sort of marathon trip, “We were still floored to really see it.” This trip takes about three full days over open ocean, and its risky. If the birds hit bad weather en route, they may run out of fuel and just drop out of the sky. Migrating birds accomplish their missions by fattening up before they leave. In the case of the blackpoll warbler they double their weight, weighing about 16 grams before take off. De Luca states, “They really just turn into flying machines. Fuel and wings and a little navigation computer chip in their head.” DeLuca concludes, “This is one of the longest non-stop overwater flights recorded for a songbird and confirms what has long been believed to be one of the most extraordinary migratory feats on the planet”.

We wish our friends a safe journey, and look forward to their return in the spring.

Late August Reports:

Dot Mooney, Monadnock Dr. August 20, turkey vulture flew over. Goldfinch eating a few coneflower seeds, then hopped onto bird bath for a few sips to wash seeds down. August 24, hydrangeas out front attracting so many bumblebees. Early evening, at least seven chipping sparrows and five doves on ground, a chickadee on feeder. August 25, 8:50 pm, a gorgeous yellow full moon rising over back woods. August 27, some pink and white mushrooms growing near stone wall in woods. Saw a hummer visiting nearby hanging plant. Another hummer arrived and they had a brief argument over the flowers, then one chased the other away–typical hummer behavior. August 28, a bunny poking around under feeder.

Doug Pederson, August 25. At Beaverbrook Rd. bridge, osprey catching a fish. [Doug sent a terrific series of photos of the action-MH]

Marian/Bill Harman, Old Colony Drive. August 30, three female turkeys in yard., hummingbird at feeder.

September Reports:

Rosemarie Koester, Providence Rd. September 4. A white hydrangea bush in front covered with so many bees, including bumble bees enjoying the flowers–“Happy to see it”. A new bird in the yard, size of a blue jay, muted striped back, tips of tail white, slender.

Dot Mooney, Monadnock Drive. September 5, a titmouse and Carolina wren on deck, checking out potted plants and having a drink from birdbaths. September 7, watched a hummer visiting geranium on deck, briefly, it was not too impressed. These tiny birds have such long journeys ahead of them. A bit later there was what must have been a family of chipping sparrows exploring lawn and shrubs outside front door. Around noon, a young female downy woodpecker on suet. She seemed unsure of how to get the suet, but finally got the idea. One dove in tree near feeder, quietly fixing her feathers. I can hear nuthatches chatting in the big trees. One grackle stopped by for a few seeds. The clean young female downy returned to suet for more. September 8, along the back lawn, most of the sumac bushes are still green, but some of the leaves are a beautiful red-orange color. September 11, A young red-bellied woodpecker on empty feeder. He must be very confused about that. Chickadees and titmice in and out. I usually notice the first fall colors come out in the vines, then the shrubs, and the trees are last. The fall feast for wildlife is emerging under the power lines. Bears are searching for whatever rich food they can find to fatten up on. My friend on Concord Rd. recently had a bear enjoying sunflower seed in her back yard. Beautiful animals, but I for one will be happy when they are all asleep.

Marian/Bill Harman, Old Colony Dr. September 7, hummingbird at feeder. September 9, what looked to be a red-breasted nuthatch in spruce tree. September 10, huge number of squirrels killed on the roads around town and on the highways (collecting acorns which seem to be more scarce this year), cardinal family with one juvenile, four crows, five goldfinches, two chickadees, titmice, white-breasted nuthatch, downy woodpecker, four grackles, broad-winged hawk came down by street after a squirrel and missed. September 11, three grackles, one red-winged blackbird. September 13, hummingbird seen (last of the year). September 14, grackles, goldfinches feeding babies. September 17, coopers hawk flew down in our back yard and scared up about seven doves, but didn’t catch one. September 23, grackles, crow, catbird on the deck railing, baby bunny eating grass in the yard.

Beth Bonner, Plain Rd. September 11, Mom turkey and her two young came back and went right to the bird feeder. The chicks have grown and obviously remember us. We last saw them on August 11. September 24, turkeys now return up to three times daily. “Each time we see them, Bruce goes out with a coffee can of mixed seed, and dumps it under the feeders. They walk a few feet away and then immediately march right up to eat the food….Last Sunday we saw Mom in our front yard and no chicks. We watched and the two chicks came out of the woods honestly across from us and stopped at the street. We could not hear if Mom was calling them, but all of a sudden they both flapped their wings and half flew across Plain Road…..It has been fun watching the chicks grow and seeing how Mom takes good care of them”.

Mary Lyman at First Parish Church. September 18, pleasantly surprised to see a red-tailed hawk sitting on the roof peak of the meeting house entry. This was my third sighting of it on the property. [Mary sent a photo-MH]

Diane Duane, Howard Rd. September 17, I was excited to see a monarch fly near an empty lot and land on some goldenrod. At home later that day, saw a monarch on our front stand of butterfly bush. Must be heading south from a northern location.

Debbie Prato, Hayrick Lane. September 24, Canada geese, mallards, black ducks, turkeys, white-breasted nuthatches, hairy and downy woodpeckers, goldfinches, house finches, robins, grasshopper sparrows, lots of sharp-shinned, red-tailed and Cooper’s hawks, tiny toad in my vegetable garden.

Len Palmer, at Rome Drive. September 25, Saw an osprey at the heron rookery. I think it is time to go south. There was a bear on Natalie Drive, Chelmsford across Rt. 27.

Squirrel on feeder – Marian Harman

Are the critters getting smarter, or am I getting dumber? This year, the squirrels and chipmunks have been besting us at every turn. It is sometimes comforting to think that humans are smarter than other animals, but if I ever believed that, I no longer do.

As some of you know, my husband and I moved to a lovely condo in the woods last winter. We had a real deck for the first time, and after erecting several feeders complete with squirrel baffles on the deck railing, we reveled in the fact that a wide variety of birds arrived quickly. We could see the birds close up while we ate breakfast. This was much better, we thought, than our pole feeder way out in the yard of the house we had moved from. We offered shelled sunflower seed, mixed seed, thistle seed, suet, and safflower seed. We had been told that birds like safflower but squirrels don’t. We were so confidant of this that we didn’t even put a baffle on the safflower feeder. All went very well for awhile, and we were even accused of stealing other people’s birds. In the spring, we hung a hummingbird feeder and were thrilled when a lovely pair started visiting several times a day. Later in the spring, we planted patio and grape tomatoes in pots on the deck and were happy when they bloomed.

But in late spring and summer, all our plans went awry. Our gray squirrel visitors were dominated by three young siblings. One of these juveniles seemed much more athletic and intelligent than the others. The safflower was the low-hanging fruit of course. At first the squirrels ate the safflower sparingly and the birds seemed to like it almost as much as the other seeds. However, our squirrels soon developed a passion for safflower and were monopolizing that feeder. Then our young genius gray squirrel started planning for tastier fare. It studied the feeders and their defenses carefully. It crawled up the poles and tested the qualities and physics of the baffles. It seemed to be triangulating angles and calculating speed and momentum of flight, as it turned its head this way and that. Suddenly, it seemed to have a plan of attack, and would try a daring move such as jumping from the porch railing over the baffle, or taking a tremendous leap from one feeder to the next. It failed a few times and ended up falling about ten feet all the way to the ground, but was completely undeterred. Eventually, it figured out that it could just spread-eagle crawl right over the long can-type baffle, like a child climbing a coconut tree. After it was up one feeder and had finished off all the food available there, it was easy business to jump over to the other feeders. It even figured out that it could get all the sugar water in our hummingbird feeder by jumping onto the roof, hanging upside down and tipping the water with one paw while lapping it all up. Now I ask you, does a squirrel need sugar water? There is a perfectly wet pond within a few feet of the deck.

Not to be deterred, we countered with attempts of our own. We separated the feeders considerably and raised them several feet higher. That didn’t help for long. At this writing, we have gotten it down to one feeder pole with mixed seed and suet, and put on a second baffle, a large cone-shaped one. For the moment, our genius is deterred, but it is testing out this new set up trying to crack the code. We have hung the hummingbird feeder on the same pole as the others.

Our other critter problem came from the chipmunks. It turns out they love tomatoes. When our tomato plants produced fruit, the chipmunks ate them all while they were still very green. I tried spraying chili pepper water on the tomatoes, but the chipmunks seemed to like that just fine. However, Agway solved our problem with a product called Repels-All.  It is a natural concoction of all sorts of nasty smelling stuff such as “putrescent whole egg solids”, fish oil, and urea. You spray it on the tomatoes and they leave them alone. I spray it after every rain. When we pick the tomatoes, I wash them and there is no residue. They taste great. Now maybe I should try spraying that stuff on the bird feeders?

Dot Mooney, Monadnock Drive. August 4, on feeder or on ground beneath, chickadee, white-breasted nuthatches, downy woodpecker, grackle, house finch and two goldfinches. A bee that looks like a tiny bumblebee has been visiting hydrangea blossoms. White mushrooms popping up here and there. Busy little hummer visiting my potted plants on deck. Three talkative white-breasted nuthatches in woods, several chickadees, a female cardinal, one chipping sparrow, several female house finches and one brightly colored male. Heard goldfinches flying overhead, heard a hawk high in the sky. August 13, goldfinch picking at seeds of my coneflower plant on deck. Pretty buff-colored squirrel still around, hanging out with the group. August 14, five doves under feeder, a hummer and a goldfinch visited deck plants and suet. August 16, female hairy woodpecker discovered suet, very happy to stay awhile. August 18, watched two bunnies enjoying whatever good greens they could find in back lawn. August 19, sat on front steps awhile, saw two red tails circling low overhead. I kept hearing their calls, then saw there were three and they were now quite high. Five doves now and a pair of cardinals. A chickadee just announced his arrival. I love goldenrod and there is some blooming along the edge of the woods. Several very busy chipmunks gathering some sort of seed under feeder. White-breasted nuthatch and two chipping sparrows. Male dove chasing after a female as usual. Two titmice poking around some nearby shrubs. As always, so many bumblebees visiting the fragrant shrub by the front walk. One red tail flew silently past over lawn and walkway, quite low. “Mostly there is something interesting going on somewhere right outside. Just pick a window and be patient.”

Susan Mudgett, Tadmuck Rd. August 7, for the past week a pair of goldfinches in the wild thistle and at least two monarch butterflies in the milkweed seen outside my window.

Diane Duane, Howard Rd. August 7. I saw two monarchs today, one in front of my house and the other at Town Hall. So far, we have seen four monarchs near our pollinator garden in the past few weeks. Also, this morning a female turkey with seven chicks.

Tom Ennis, Almeria Circle. August 7, trees in the yard seem to have grape vines winding their way through the forest. This is a new find.

Donne Cecere, Calista Terrace. August 13, Summer report: we have had house wren nests built in three birdhouses. They like to talk loudly and make great watching. A hawk came down swiftly and took a chipmunk. Another hawk startled me when I was tending to my garden, just brushed by my head and swooped up another chipmunk. The pesky squirrels seem to have multiplied. Also, mourning doves, robins, tufted titmouse, cardinals, black-capped chickadees, blue jays, grackles, red-winged blackbirds, house finches, goldfinches, white-breasted nuthatches, rose-breasted grosbeaks, northern flicker at suet, and hummingbirds.

Leslie Thomas at Lyberty Way. August 20, two grouse seen at the entrance to the road.

Sue Bonner, Plain Rd. August 22, our mother turkey returned on August 4, with only two chicks. We continued to see the female and two chicks once or twice a day August, 5, 6, 9, 10 and 11. At the feeder, we put our mixed seed, black oil sunflower and suet and safflower. Since putting out the safflower, we seem to have more goldfinches, house finches and titmice. Other birds at the feeders include lots of sparrows, grackles, starlings, cardinals and blue jays. A crow tried to figure out how to get to the suet by hanging from the shepherd’s crook and trying to bend down to reach the suet. We have a container of water on our stonewall and a plant saucer with water on our deck. Squirrels, chipmunks and birds enjoy water at both places. The birds use the saucer on the deck for bathing too. We have several bunnies that seem to like certain plants in my perennial bed. My red-orange Millions Bells hanging plant has been a magnet for the hummingbird. We have had nine squirrels, two of which are light tan, at our stonewall where we put seed, under the feeders and even hanging on the feeders, despite the squirrel baffles. Our six blueberry bushes, which we did not net this year, have fed squirrels, chipmunks, birds, the turkey and her chicks and three deer.

Every trail a vista to share – Lowell Sun

Honorary Trust Director, Bill Harman

With rakes and clippers, Bill Harman and his team of volunteers keep Westford’s paths clear so all can enjoy. 

WESTFORD — Bill Harman walked along a neatly carved path through the woods, occasionally pausing halfway through a sentence to crouch and pick up a stray wrapper or piece of rubber from the ground.

Cleaning up the town’s natural settings is, at this point, second nature to him — after all, every week for more than five years, Harman has organized a group of volunteers to spend an hour walking through Westford’s trails, clearing any debris so they remain accessible to others.  read more…
