MONARCH BUTTERFLY MIGRATION ALERT FOR CAPE ANN, NEWBURY, IPSWICH, PLUM ISLAND!

Monarchs are currently migrating, albeit in small numbers, throughout the North Shore. The butterflies arrived several days ago and because of the rainy weather, they are in a holding pattern. When the sun reappears, look for Monarchs on any still-blooming  garden favorites such as zinnias, as well as wildflowers. Please send an email or comment in the comment section if you see Monarchs in your garden or while outdoors over the weekend and upcoming week. Thank you!

Many species of asters and goldenrods have finished flowering; instead the Monarchs are fortifying for the long journey by drinking nectar at Black Mustard flowers, and even Dandelions.

Although not native to North America, Black Mustard (Brassica nigra) is beneficial to bees and butterflies for late season sustenance. Don’t you love its lemony golden beauty in the autumn sunlight?

Black Mustard is not the easiest nor most efficient plant for Monarchs to draw nectar from. I never see the butterflies on Black Mustard unless it is very late in the migration and there are few other choices available.

The ray flowers of asters provide a convenient landing pad for butterflies. Panicle-shaped flowering plant, such as goldenrods, also provide a convenient landing pad while supplying a smorgasbord of nectar rich florets. Black Mustard provides neither. You can see in several photos in an upcoming post that the Monarchs are nectaring with their legs gripped tightly around the base of the flower.

Black Mustard is an annual plant native to Eurasia and North Africa. Cultivated widely as a condiment, medicinally, and vegetable, it came to North America via the early colonists. The plant is in bloom from May through October, or until the first hard frost, and grows well in disturbed man-made sites.

Black Mustard is a member of the Brassicaceae, also classically called the Cruciferae (Latin, meaning ‘cross-bearing’) in reference to its four ‘crossed petals’, which is commonly known as the mustard family. Black Mustard is related to cabbage, broccoli, Brussel sprouts, kohlrabi, kale, turnips, and watercress.

ATTENTION BIRD LOVING AND PHOTOGRAPHY FRIENDS – RUN, DON’T WALK, TO PARKER RIVER NATIONAL WILDLIFE REFUGE!

According to Rangers at Parker River, the 2020 fall migration at Plum Island is the best they have ever seen, with over 180 species on the current list (last ten days).

Perhaps the lessened human activity across North America has allowed for many species of birds to flourish.

I was filming at a location nearby at dawn or I would have gone at my usual daybreak time, which I find is the best time to observe birds, and wildlife of all sorts. Mid-day is not the best time to go, but it was my one and only chance and I wanted to check it out. Plum Island is gorgeous whenever you go. Autumn hues are beginning to show (especially the brilliant purple-red of PI), there are great swaths of goldenrods in full bloom, and there is a wealth of bird food, berries and seed heads, for the birds to forage upon. Stage Island and Hellcat are two current hotspots for bird sightings.

When you drive up to the kiosk where you show your membership card, ask for the species list of birds seen recently. Or click this link here:

WHY THE SAND IS PURPLE AND PINK ON CRANE BEACH, PLUM ISLAND, AND OTHER NORTH SHORE BEACHES

Hard to miss in the wintertime both at Crane Beach and at Plum Island are the layers and swirls of pink and purple sand. On a recent visit to Revere Beach I noticed there were also rivulets of pink and purple sands.

The pink and purple are mineral deposits of rose quart and garnet and come to north of Boston beaches via the White Mountains. Water and wind worn rock is carried in river waters until it meets the ocean and becomes deposited on barrier beaches. We mostly see the garnet and quartz deposits in winter as storms erode the dunes, leaving the heavier minerals exposed. During the spring and summer, the lighter white quartz sand blows back over the dunes and covers the heavier sand.

JEOL is a supplier of electron microscopes, ion beam instruments, mass spectrometers and NMR spectrometers. On a visit to Plum Island looking for Snowy Owls, several JEOL employees found purple sand. They analyzed it using an optical microscope, a scanning electron microscopes (SEM) and an energy dispersive X-Ray spectrometer (EDS).

From JEOL USA –

At first look under the optical microscope, the granules of sand appeared like scattered jewels of many colors; predominantly glassy pink angular grains, with smaller quantities of milky white rounded grains, clear angular grains, black grains (some magnetic and some not), and even the occasional green.

What could be the cause of the purple color? The answer was one that came as no surprise to the scientist, but was exciting for the beach walkers because they had an exact answer to a question that no doubt is one that many people have when they visit Plum Island – which was actually named for its beach plum bushes, not the plum-colored sand.

When large amounts of fine grained pink is intermixed with a smaller number of darker grains and dampened by rain or sea water the human eye will “see” the sand as a much darker pink to almost purple. The two most common pink minerals are rose quartz (while quartz is one of the two most common minerals on earth, the pink rose quartz variety is not so common ,especially in the New England geology, and is found only in a few isolated pegmatite deposits in NH & southern Maine which are where most gemstones originate) and the solid solution series of almandine and pyrope garnet which is also a very common mineral (and is quite common in the Seacoast area from the abundance of metamorphic rocks called mica schist and from contact metamorphism. This is also why many commercial sandpaper products have a pink color as the angular hard gains of almandine / pyrope garnet are the perfect abrasive. The most likely candidates for the white and clear are any of the feldspars and or quartz. The green is most likely epidote. Just based on the optical examination these are no more than educated logical guesses (but still guesses).

Vern Robertson, JEOL’s SEM Technical Sales Manager, originally examined the grains under a low power optical stereo microscope with the above conclusions. In addition to providing technical and scientific support to JEOL SEM customers for a multitude of applications, Vern holds a degree in Geology. After a cursory look optically, it was time to get down to some spectroscopic analysis to determine the actual mineral species present in the sand.

Individual grains of various colors were selected and mounted for examination with the JSM-6010LA+ InTouchScope SEM and for analysis using EDS. The SEM allows much higher magnification imaging with greater depth of field than a traditional OM and the low vacuum capability allows examination of the sample without the traditional conductive coating that needs to be applied for SEM imaging. However, it generates images in only black & white (electrons have no color!). One specialized detector in the SEM, the Backscatter Electron Detector, yields images with the gray level intensity directly proportional to the average atomic number (or density). This means that minerals containing only lighter elements like O, Si are darker in appearance to minerals that contain heavier elements like Fe or any of the metallic or rare earth elements.

Once located, each grain can be analyzed with the EDS. When an electron beam hits a sample it creates not only an image from the emitted electrons but creates X-rays, which when collected in a spectrum, indicate what elements are present and at what concentrations. This allows not only the elemental composition of the individual grains to be determined but the concentrations can be compared to known stoichiometry of the suspected mineral grains. The combination of color and magnetic properties from OM examination and the chemical makeup of the individual grains yield the answer.

The purple color (or more appropriately, pink color) comes from the abundance of almandine-pyrope garnet with a nominal solid solution composition of Fe3+2Al2Si3O12 to Mg3+2Al2Si3O12. As expected, the white grains are a mix of feldspars but mostly K-feldspar (potassium alumino-silicates) and quartz SiO2. The black nonmagnetic grains were a mix of a pyroxene called augite which showed its characteristic strong cleavage, (Ca,Na)(Mg,Fe,Al)(Si,Al)2O6 , and a mix of ilmenite FeTiO3 and hematite Fe2O3 which are the magnetic components. The green was confirmed to be epidote Ca2(Al,Fe)3(SiO4) 3(OH). With the exception of the high concentration of garnets the rest are common minerals one would expect to find in sands.

A SOGGY SNOWY OWL FOR A SOGGY DAY

This sweet messy-faced girl was relaxing on the limb of a craggy tree after what had clearly been a successful morning hunt. She coughed up a pellet while enjoying a rare quiet moment perched in the branches.

BEAUTIFUL RED-TAILED HAWK TAKES FLIGHT

Red-tailed perched on a chimney scanning the marsh with its keen vision.

The Red-tailed Hawk’s vision is eight times more powerful than a human’s, allowing it see a small rodent such as a mouse or vole from 100 feet away. It dove into the tall dry grass making a loud crackly rushing sound but, came up empty-mouthed. Again it flew to the top of the Pink House chimney from where, only a few moments later, it made a second dive.

When diving to catch prey, their speed may exceed 120 miles per hour, and no joke, this Hawk’s speed appeared to increase as it became torpedo-like in shape.

Successful hunting! I only captured a photo of the second half of its flight from a distance; nonetheless, you can see the mouse (or vole) in its mouth in the last photo.

MORE SNAPSHOTS OF THE BEAUTIFUL SHORT-EARED OWL, SNOWY OWL, TENDERCROP FARM, AND IPSWICH CLAMBAKE

Charlotte and I had a wonderful adventure morning checking on the owls at Plum Island. We observed several Harrier Hawks flying low over the marsh grass hunting for prey, a Short-eared Owl perched on a craggy tree, and a Snowy parked for the morning far out in the dunes. We played on the beach and she had a blast zooming up and down the boardwalk at lot no. 2.

Tiny white wedge in the distance

We next stopped at the refuge headquarters to play in the marsh boat that is part of the exhibit about the Great Salt Marsh. She brought along her own stuffed Snowy to join on the boat ride.

Next destination was a visit to see the farm friends at Tendercrop Farm. Currently in residence are a turkey, ginormous steer, pony, chickens, ducks, llama, and the sweetest miniature goat who is just wonderful with toddlers.

I purchased the best steaks we have ever had, Tendercrop’s own grass fed rib-eye, made even more magnificent cooked to perfection by Alex, with a beautiful red wine demi-glace.

Everything at Tendercrop Farm is always amazingly delicious. They have the freshest and best selection of fruits and vegetables during the winter months, bar none.

Great bunches of freshly cut pussy willows are for sale at Tendercrop

Last stop was lunch at the Ipswich Clambake. The owners and staff are just the most friendly. The clam chowder at the Clambake is perfection. Charlotte and I shared a mini super fresh fried clam appetizer and that, along with the chowder, made the best sort of lunch to top off our fun adventure morning.

Tendercrop Farm is located at 108 High Road, 1A, in Newbury.

Ipswich Clambake is located at 196 High Street, 1A, in Ipswich.

Clear Evidence of the Destructive Force of Global Warming on the Massachusetts Coastline and How This Negatively Impacts Local Wildlife

Female Piping Plover Sitting on an Egg

The recent winter storms of 2018 have provided empirical evidence of how global climate change and the consequential rising sea level is impacting the Massachusetts coastline. Whether broken barriers between the ocean and small bodies of fresh water, the tremendous erosion along beaches, or the loss of plant life at the edge of the sea, these disturbances are profoundly impacting wildlife habitats.

The following photos were taken after the March nor’easter of 2018 along with photos of the same areas, before the storm, and identify several specific species of wildlife that are affected by the tremendous loss of habitat.

Barrier Beach Erosion

Nesting species of shorebirds such as Piping Plovers require flat or gently sloping areas above the wrack line for chick rearing. Notice how the March nor’easter created bluffs with steep sides, making safe areas for tiny chicks nonexistent.

You can see in the photos of Good Harbor Beach (top photo and photos 3 and 4 in the gallery) that the metal fence posts are completely exposed. In 2016, the posts were half buried and in 2017, the posts were nearly completely buried. After the recent storms, the posts are fully exposed and the dune has eroded half a dozen feet behind the posts.

In the photo of the male Piping Plover sitting on his nest from 2016 the metal posts are half buried.

Although scrubby growth shrubs and sea grass help prevent erosion, the plants have been ripped out by the roots and swept away due to the rise in sea level.

Plants draw tiny insects, which is food for tiny chicks, and also provide cover from predators, as well as shelter from weather conditions. If the Piping Plovers return, will they find suitable nesting areas, and will plant life recover in time for this year’s brood?

Other species of shorebirds that nest on Massachusetts’s beaches include the Common Tern, Least Tern, Roseate Tern, American Oyster Catcher, Killdeer, and Black Skimmer.

Where Have All the Wildflowers Gone?

Wildflowers are the main source of food for myriad species of beneficial insects such as native bees and butterflies.

Monarch Butterflies arriving on our shores not only depend upon milkweed for the survival of the species, but the fall migrants rely heavily on wildflowers that bloom in late summer and early fall. Eastern Point is a major point of entry, and stopover, for the southward migrating butterflies. We have already lost much of the wildflower habitat that formerly graced the Lighthouse landscape.

Masses of sea debris from the storm surge washed over the wildflower patches and are covering much of the pollinator habitat at the Lighthouse.

Broken Barriers

American Wigeon Migrating at Henry’s Pond

Barriers that divide small bodies of fresh water from the open sea have been especially hard hit. The fresh bodies of water adjacent to the sea provide habitat, food, and drinking water for hundreds of species of wildlife and tens of thousands of migrating song and shorebirds that travel through our region.

The recently rebuilt causeway (2014) between Niles Pond and Brace Cove was breached many times during the nor’easter. The causeway is littered in rocks and debris from the sea.

The causeway being rebuilt in 2014.

The road that runs along Pebble Beach, separating the sea from Henry’s Pond has been washed out.

The footsteps in the sand are where the road ran prior to the storm.

Mallards, North American Beavers, Muskrats, North American River Otters, and Painted Turtles are only a few examples of species that breed in Massachusetts fresh water ponds and wetlands. All the wildlife photos and videos were shot on Cape Ann.

Migrating Black-bellied Plover

Cape Ann is hardly alone in coping with the impact of our warming planet and of rising sea level. These photos are meant to show examples of what is happening locally. Regions like Plymouth County, which include Scituate and Hingham, have been equally as hard hit. Plum Island is famously heading for disaster and similar Massachusetts barrier beaches, like Cranes Beach, have all been dramatically altered by the cumulative effects of sea level rising, and recently accelerated by the devastating winter storms of 2018.

To be continued.

Gloucester From Plum Island

I think these are Gloucester’s wind turbines, looking across Ipswich Bay. The photo was taken at Sandy Point. Please write if you believe otherwise. Thank you!

Super windy and chilly Saturday afternoon but nonetheless beautiful. I renewed our annual Parker River National Wildlife Refuge pass, which is good for one year, and think it is the best twenty dollars spent. Kudos for being the cutest pass, too!
