A young Mute Swan arrived at Niles Pond this morning. He/she seems a bit travel weary and spent most of the day sleeping. As a matter of fact, I didn’t see him eat once. This is very unusual behavior for Mute Swans who spend their days alternating between foraging, preening, resting briefly, and then resuming eating.
He at first was closer to shore, but a Coyote was skittering around the edge of the pond this morning and perhaps that is why the young visitor moved to the center of the pond.
People always ask, what causes these gigantic rings?
There’s an old weather saying: ring around the moon means rain soon. There’s truth to this saying, because high cirrus clouds often come before a storm. Notice in these photos that the sky looks fairly clear. After all, you can see the sun or moon. And yet halos are a sign of high, thin cirrus clouds drifting 20,000 feet or more above our heads.
These clouds contain millions of tiny ice crystals. The halos you see are caused by bothrefraction, or splitting of light, and also by reflection, or glints of light from these ice crystals. The crystals have to be oriented and positioned just so with respect to your eye, in order for the halo to appear.
That’s why, like rainbows, halos around the sun – or moon – are personal. Everyone sees their own particular halo, made by their own particular ice crystals, which are different from the ice crystals making the halo of the person standing next to you.
That’s a good question that is not easy to answer accurately because no halo frequency statistics are collected except in one or two mid latitude European countries.
We need to distinguish between (a) halos formed by low level diamond dust during very cold weather and (b) halos formed by ice crystals in high cirrus cloud.
Obviously (a) halos only occur in Polar regions or countries with very cold winters (Canada for example is not high latitude).
(b) Halos can occur anywhere on the planet during winter or summer. Their frequency depends on the frequency of cirrus coverage and whether it has had a history such that it contains halo forming crystals. The latter is hard to predict. For example, there are major differences in halo frequencies and types of halos across even 200 miles [300 km] in the UK.
Bottom line: Halos around the sun or moon are caused by high, thin cirrus clouds drifting high above your head. Tiny ice crystals in Earth’s atmosphere create the halos. They do it by refracting and reflecting the light. Lunar halos are signs that storms are nearby.
The Coot’s whacky-looking feet only adds to the charm of this adorable waterbird, with its chicken-shaped silhouette, white pointed beak that ends in a sploge of maroon, and garnet, bead-like eyes. Oh, and when the light hits just right, you can see the Coot’s feet are colored in shades of blue, green, and yellow.
The American Coot’s foot is an all-purpose foot so to speak. The lobes serve the bird well for both walking on dry land and for swimming. Most ducks have webbed feet, which are great for propelling through water, but which don’t work very well on land. The Coot’s lobes fall back when lifting its foot, which aids in walking on a variety of surfaces including grass, ice, and mud.
The Coot’s oversized feet also help in becoming airborne; the bird must run across the surface of the water and flap its wings vigorously in order to take off. Its palmate toe helps it swim, and lastly, the Coot uses its strong feet for battling other Coots.
The past week Eastern Point has seen a wonderful influx of wildlife, in addition to the beautiful creatures already wintering over and migrating through.
On Tuesday before Thanksgiving, a great raft of Ring-necked Ducks joined the flock of Buffleheads and Mallards at Niles Pond. Five chunky American Coots have been there for over a week, and two female Ruddy Ducks have been spotted.
Fifteen Harbor Seals were sunning and basking on the rocks at Brace Cove on Wednesday, along with several Bonaparte’s Gulls that were diving and foraging in the waves. The increasingly less timid Lark Sparrow is still here, too.
The most enigmatic of Great Blue Herons criss crosses the pond a dozen times a day but, unlike last year’s fall migrating GBH, who allowed for a closer glimpse, this heron is super people shy. He has been here for about a week and was present again today.
This morning I watched the four beautiful Mute Swans depart over Brace Rock, in a southerly direction. Will they return? Mute Swans migrate from body of water to body of water within a region. Perhaps they will return, or they could possibly have flown to a nearby location–further exploring our Island.
Leaving Niles Pond this morning and flying over Brace Cove.
The sweet Lark Sparrow has been spotted daily at Eastern Point now for over two weeks. I’ve been able to take a longer look on a sunny day and think he is an immature Lark Sparrow because he lacks the rich chestnut color of an adult.
On one fine chilly, chilly morning, he even let me spend more than a few moments watching as he dozed in the sun while puffing his feathers for warmth.
The Lark Sparrow spends a good deal of time foraging on the ground for tiny seeds. When disturbed, he flies up into the trees and at that moment you can catch a glimpse of the white outlined feathers of the bird’s long rounded tail.

Unlike Song Sparrows that dart and zoom horizontally across the landscape, when heading to the next location, the Lark Sparrow flies upward in more of a whirring helicopter movement. I love this little bird and if he stays all winter I hope he will find plenty of seeds to eat.
Compare and contrast the Song Sparrow to the Lark Sparrow. Both species are currently at Eastern Point/Niles Pond area. Both species forage on the ground for tiny seeds. The breast of the Song Sparrow is streaky while the breast of the Lark Sparrow is solid white with a dot of black feathers centered at the upper chest.

Don’t you find it fascinating, these avian visitors that are so far off course that find themselves on our shores? Here’s an account from 1905 —
The Lark Sparrow in Massachusetts.– On August 12, 1905, at Ipswich, Massachusetts, I observed at close range a Lark Sparrow (Chondesres grammacus). This makes the sixth record of this species for the State, and the fourth for Essex County. Nearly a year before this, on August 21, 1904, I took at Ipswich an adult male Lark Sparrow (Birds [Auk 104 General Notes. I. Jan. of Essex County, p. 268). It has occurred to me that stragglers in the migrations along our Eastern Coast may not be so very rare, but that they are overlooked, being mistaken for Vesper Sparrows, owing to the ‘white outer tail feathers. In both of the above instances, however, the slightly fan-shaped tail, and the fact that the white was not confined to the two outer feathers, as in the Vesper Sparrow, attracted my eye. The characteristic marking on the side of the head in the Lark Sparrow, seen with a glass within thirty feet, made the diagnosis in the second ca. From the Supplement to the Birds of Essex County by Charles Wendell Townsend.
A very rare-for-these parts Lark Sparrow was spotted by numerous birders today and yesterday at Niles Pond. The beautiful little songster kept either close to the ground foraging on tiny seeds or well camouflaged in the crisscrossing branches of trees and shrubs.

We mostly see Song Sparrows around Niles at this time of year. Compare in the above photos how plain the breast of the Lark Sparrow is to that of the heavily streaked Song Sparrow’s underparts. I write rare-for-these-parts because the Lark Sparrow is entirely out of its range as you can see in the first attached map below.
A second rare bird has been spotted on Eastern Point, a Western Kingbird. It was a rough day for photographing, too overcast, so here is a photo from wikicommons media so that if you are around the Point, you will know what to look for. The Western Kingbird is also far outside its range.
