Walking along the edge of the pond I heard a new-to-my-ears sound, an odd sort of mewing, repeated over and over again. What could that be? I snuck along as quiet as could be following the sound. To my amazement, it was a pair of Muskrats cavorting in the reeds, and they were courting and mating!!! You can just barely make out two together in the photo with the dense reeds, too dense to get a good photo, but not too dense to see what they were up to.
A female Muskrat is ready to breed at only one year of age. The breeding season lasts from March through August. A pair will mate while partially submerged, or on water-logged debris above the surface (where our little pair was mating). She may have 2-3 litters per year, with an average of 6 to 8 kits per litter.
Lest folks worry the pond will become overrun with Muskrats, they are a relatively short-lived mammal and have many, many predators including Snapping Turtles, large fish, Eastern Coyotes, Red and Gray Foxes, Weasels, River Otters, Bobcats, Great Horned Owls, and Northern Harriers. But their chief enemy are Minks and Raccoons.
For our reader’s general information, Muskrats are easy to distinguish from Beavers. They are about a tenth the size; Muskrats weigh 1 to 4 pounds whereas Beavers weighs 30 pounds or more. The muskrat’s tail is not large large and flat, but slender and elongated.
After Thursday’s storm we tried going for a beach walk at Good Harbor, Brace Cove, and Niles before giving up and finding a less windy stroll along Niles Pond. The water was a gorgeous deep ultramarine and even the inner harbor was beautiful with whitecaps.
I was concerned and did not not think the young heron could possibly find enough food after Niles Pond froze solidly over. The pond was thick with a heavy layer of ice, so thick people had been skating.
Several days ago when out for a walk, I heard a krickly sound coming from the reeds along the pond’s edge. A beautiful Red Squirrel ran across my path. A few moments later, the same krickly krickly sound, only this time when I peered in, there was the juvenile BCNH, sleepy-eyed and shifting on the cold ice.
I walked out onto the ice adjacent to where he had been standing and there, very clearly, was a trail of his perfectly delineated tracks. Not only that, but there was a hole in the ice, surrounded by several sets of his tracks. Having observed BCNH during the summer months standing stock still in one place for hours on end, I can just imagine that he must have stood over that hole for hours waiting for his dinner to swim by. Simply amazed!
If you are having difficulty viewing the photos large, double click and you should be able to see full size.
My camera lens was too long to get a close up of the tracks. I was only able to take these cell phone pics, but you can still see very clearly the heron’s tracks in the snowy ice, and the ice hole.Cape Ann is located at the tippy northern end of their year round Atlantic coastal range.
He mostly stays well-hidden in the dense thickets at water’s edge. I’ve read that Night Herons occasionally spend the entire winter in northern regions. Cape Ann is at the tippy edge of their year round coastal range. Let’s hope this youngster will survive the next several months.
Our shores abound with wonderful wild creatures we more often see in wintertime, and species we can view better because the trees are bare. The duo of male American Wigeons are still here, as are the pair of Pipits. I watched yesterday afternoon as the Pipits flew away from the beach in unison, and then returned together about twenty minutes later to continue to forage in the seaweed and sand.
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.
