Isn’t it amazing how when you begin a conversation with someone, inevitably, it always leads to the weather. What would we do if we didn’t have the weather to talk about. Maybe some of us would never speak.

Whether you’re at the supermarket, church, or just bumping into a friend on the street, the conversation always goes something like, “What a nice day?” or “boy it sure is hot enough.” Get the idea?

Well, the other day, a colleague and I started talking about whether this recent stretch of weather constituted an “Indian Summer.” Which prompted me to think, “what really is an Indian summer and what determines whether we have one or not?”

An Indian summer is unseasonably warm, dry and calm weather, usually following a period of colder weather or frost in the late autumn, in September, October or early November. The Old Farmers Almanac describes it as taking place between November 11 and 20. It states, “During true Indian summer, the atmosphere looks hazy or smokey, and the weather is calm and dry.”

Modern ideas on what an Indian summer constitutes vary, but the most widely accepted value for determining whether an Indian summer is occurring is that the weather must be above 70 degrees for seven days after the autumnal equinox. The term Indian summer has been used for more than two centuries. The origin of other “Indian” phrases are well-known as referring to North American Indians, who prefer to be called Native Americans, or, in Canada, First Nations. The term Indian summer reached England in the 19th century, during the heyday of the British Raj in India. This led to the mistaken belief that the term referred to the Indian subcontinent. In fact, the Indians in question were the Native Americans, and the term began use there in the late 18th century.

Indian summer is first recorded in Letters From an American Farmer, a 1778 work by the French-American soldier-turned-farmer J. H. St. John de Crevecoeur: “Then a severe frost succeeds which prepares it to receive the voluminous coat of snow which is soon to follow; though it is often preceded by a short interval of smoke and mildness, called the Indian Summer.”

There are many references to the term in American literature in the following hundred years or so. In the 1830s Indian summer began to be used figuratively, to refer to any late flowering following a period of decline. It was well enough established as a phrase by 1834 for John Greenleaf Whittier to use the term that way, when in his poem “Memories,” he wrote of “The Indian Summer of the heart!”

Or, Thomas DeQuincey, in a republishing of Bentley’s Works of Thomas DeQuincey, 1855, wrote: “An Indian summer crept stealthily over his closing days.”

Also, in his story The Guardian Angel, Oliver Wendell Holmes mentions “an Indian summer of serene widowhood.”

As a climatic event it is known throughout the world and is most frequently associated with the eastern and central states of the U.S., which have a suitable climate to generate the weather pattern. For example, a wide variation of temperature and wind strength from summer to winter.

Why Indian? Well, no one knows but, as is commonplace when no one knows, many people have guessed.

Some say it was from the prairie fires deliberately set by Indian tribes; from raids on European settlements by Indian war parties, which usually ended in autumn; or, in parallel with other Indian terms, it implied a belief in Indian falsity and untrustworthiness and that an Indian summer was a substitute copy of the real thing.

But my grandfather, who could spin a yarn with the best of them, had the most creative I’ve ever heard.

It seems an Indian chief was concerned about a hunting party that was delayed in returning from a late summer gathering of meat for the winter. The year had been an extremely difficult one and the tribe needed the buffalo, deer and turkey meat for their winter consumption, and the hides for clothing and shelters. Fearing the crops in the fields would go to waste before the braves returned to harvest, the chief sat at his campfire and began to feverishly smoke a pipe, and did so for days, until the air was filled with smokey, hot air.

Once the hunting party made its return, the air was still warm enough to gather the crops that had not been damaged by frost, that the chief feared would be destroyed by the impending cold weather. By warming the air with the smoke from his pipe, the chief, essentially, saved the crops.

Makes sense to me.

We’ve all heard them. The honking sounds overhead as the Canada geese move south in their familiar V formation. Let’s learn a little more about these large birds that at one time were considered extinct.

The Canada goose, Branta canadensis, is a large wild goose species. It is native to arctic and temperate regions of North America, and its migration occasionally reaches northern Europe. Like most geese, the Canada goose is primarily herbivorous and normally migratory; it tends to be found on or close to fresh water.

Extremely skilled at living in human-altered areas, Canada geese have established breeding colonies in urban and cultivated habitats, which provide food and few natural predators. The success of this common park species has led to its often being considered a pest species because of its excrement, its depredation of crops, its noise, its aggressive territorial behavior towards both humans and other animals, and its habit of begging for food (caused by human hand feeding).

The Canada goose was one of the many species described by Carl Linnaeus in his 18th-century work Systema Naturae.

According to the Oxford English Dictionary, the first citation for the ‘Canada goose’ dates back to 1772. The Canada goose is also colloquially referred to as the “Canadian goose”. A persistent urban legend gives the name origin as after an ornithologist surnamed “Canada,” but this is false.

Canada geese range from 30 to 43 inches in length and have a 50–73 inch wingspan. The male Canada goose usually weighs 5.7–14.3 pounds. The female looks virtually identical, but is slightly lighter at 5.3–12.1 pounds, and generally 10 percent smaller in linear dimensions than the male counterparts. The honk refers to the call of the male Canada goose, while the hrink call refers to the female goose. The calls are similar, however, the hrink is shorter and more high-pitched than the honk of males.

This species is native to North America. It breeds in Canada and the northern United States in a wide range of habitats. The Great Lakes region maintains a very large population of Canada geese. Canada geese occur year-round in the southern part of their breeding range, including most of the eastern seaboard and the Pacific coast. Between California and South Carolina in the southern United States and northern Mexico, Canada geese are primarily present as migrants from further north during the winter.

By the early 20th century, overhunting and loss of habitat in the late 19th century and early 20th century had resulted in a serious decline in the numbers of this bird in its native range. The giant Canada goose subspecies was believed to be extinct in the 1950s until, in 1962, a small flock was discovered wintering in Rochester, Minnesota. Harvey K. Nelson, talked Forrest Lee into leaving Minnesota to head the center’s Canada goose production and restoration program. Forrest soon had 64 pens with 64 breeding pairs of screened, high-quality birds. The project involved private, state, and federal resources and relied on the expertise and cooperation of many individuals. By the end of 1981, more than 6,000 giant Canada geese had been released at 83 sites in 26 counties in North Dakota. With improved game laws and habitat recreation and preservation programs, their populations have recovered in most of their range, although some local populations may still be declining.

In recent years, Canada goose populations in some areas have grown substantially, so much so that many consider them pests for their droppings, bacteria in their droppings, noise, and confrontational behavior. This problem is partially due to the removal of natural predators and an abundance of safe, man-made bodies of water near food sources, such as those found on golf courses, in public parks and beaches, and in planned communities. Due in part to the interbreeding of various migratory subspecies with the introduced nonmigratory giant subspecies, Canada geese are frequently a year-around feature of such urban environments.

Contrary to its normal migration routine, large flocks of Canada geese have established permanent residence along the Pacific coast of North America from south-western British Columbia (specifically Vancouver Island and British Columbia’s Lower Mainland), south to the San Francisco Bay area of Northern California. There are also resident Atlantic coast populations, such as on Chesapeake Bay, in Virginia’s James River regions, and in the Triangle area of North Carolina (Raleigh, Durham, Chapel Hill), and nearby Hillsborough. Some Canada geese have taken up permanent residence as far south as Florida, in places such as retention ponds in apartment complexes. In 2015, the Ohio population of Canada geese was reported as roughly 130,000, with the number likely to continue increasing. Many of the geese, previously migratory, reportedly had become native, remaining in the state even in the summer. The increase was attributed to a lack of natural predators, an abundance of water, and plentiful grass in manicured lawns in urban areas.

Canada geese are primarily herbivores, although they sometimes eat small insects and fish. Their diet includes green vegetation and grains. The Canada goose eats a variety of grasses when on land. The Canada goose also eats beans and grains such as wheat, rice, and corn when they are available. In the water, it feeds from aquatic plants.

In urban areas, it is also known to pick food out of garbage bins. They are also sometimes hand-fed a variety of grains and other foods by humans in parks. Canada geese prefer lawngrass in urban areas. They usually graze in open areas with wide clearance to avoid potential predators.

Canada geese are known for their seasonal migrations. Most Canada geese have staging or resting areas where they join up with others. Their autumn migration can be seen from September to the beginning of November. The early migrants have a tendency to spend less time at rest stops and go through the migration much faster. The later birds usually spend more time at rest stops. Some geese return to the same nesting ground year after year and lay eggs with their mate, raising them in the same way each year. This is recorded from the many tagged geese which frequent the East Coast.

Flying in the V formation has been the subject of study by researchers. The front position is rotated since flying in front consumes the most energy.

The lifespan in the wild of geese that survive to adulthood ranges from 10 to 24 years.

Canada geese instinctively nest on higher ground near water. Known predators of eggs and goslings include coyotes, Arctic foxes, northern raccoons, red foxes, large gulls, common ravens, American crows, carrion crows and both brown and American black bears.

Once they reach adulthood, due to their large size and often aggressive behavior, Canada geese are rarely preyed on, although prior injury may make them more vulnerable to natural predators. Beyond humans, adults can be taken by coyotes and grey wolves. Avian predators that are known to kill adults, as well as young geese, include snowy owls, golden eagles and bald eagles and, though rarely on large adult geese, great horned owls, and peregrine falcons. Adults are quite vigorous at displacing potential predators from the nest site, with predator prevention usually falling to the larger male of the pair. Canada geese are quite wary of humans where they are regularly hunted and killed, but can otherwise become habituated to fearlessness towards humans, especially where they are fed by them. This often leads to the geese becoming overly aggressive towards humans, and large groups of the birds may be considered a nuisance if they are causing persistent issues to humans and other animals in the surrounding area.

Canada geese are susceptible to avian bird flus.

In North America, nonmigratory Canada goose populations have been on the rise. The species is frequently found on golf courses, parking lots, and urban parks, which would have previously hosted only migratory geese on rare occasions. Owing to its adaptability to human-altered areas, it has become one of the most common waterfowl species in North America. Canada geese are protected from hunting and capture outside of designated hunting seasons in the United States by the Migratory Bird Treaty Act, and in Canada under the Migratory Birds Convention Act. In both countries, commercial transactions such as buying or trading are mostly prohibited and the possession, hunting, and interfering with the activity of the animals are subject to restrictions.

In Maine, the Early Canada geese may be hunted from September 1 – 25, in the north, south and coastal zones. The Regular Canada Geese, including white-fronted geese, may be hunted, in the north zone, from October 1 through December 9; in the south zone, October 1 through October, and October 30 through December 26; and coastal zone October 1 through October 12, and October 27 through January 2, 2021.

Canada geese have been implicated in a number of bird strikes by aircraft. Their large size and tendency to fly in flocks may exacerbate their impact. In the United States, the Canada goose is the second-most damaging bird strike to airplanes, with the most damaging being turkey vultures. Canada geese can cause fatal crashes when they strike an aircraft’s engine. The FAA has reported 1,772 known civil aircraft strikes within the United States between 1990–2018.

As a large, common wild bird, the Canada goose is a common target of hunters, especially in its native range. Drake Larsen, a researcher in sustainable agriculture at Iowa State University, described them to Atlantic magazine as “so yummy…good, lean, rich meat. I find they are similar to a good cut of beef.”

In 2000, the North American population for the geese was estimated to be between 4 million and 5 million birds.

During the still of the night at camp, we can hear the sounds of barred owls communicating with each other.

One night last week, we could hear three calling out for each other from different locations. It’s not quite as soothing as listening to the loons, but it does put me back to sleep.

However, one evening, one of our neighbors said they heard a screech owl one evening. That got me to thinking. I didn’t think there were any in Maine.

Generally, it is known there aren’t that many different species of owls in Maine. Mainly, we have the Great Horned Owl, Northern Saw-Whet Owl and the very common Barred Owl. The Barred Owl and the Great Horned Owl live in a wide variety of forested habitats and occupy dense forests, open woodlands, clear-cuts, and even urban environments such as golf courses, cemeteries, and parks with adjacent woodlots.

But first, let’s look at the screech owl.

The northern screech-owls are found in eastern states, such as New Jersey and New York. The screech owls are named for their piercing calls. The normal territorial call is not a hoot as with some owls, but a trill consisting of more than four individual calls per second given in rapid succession (although the sound does not resemble screeching or screaming). They also have a kind of “song” which is used in courtship and, as a duet, between members of a pair. Calls differ widely between species in type and pitch, and in the field are often the first indication of these birds’ presence, as well as the most reliable means to distinguish between species. The distinctness of many species of screech owls was first realized when vastly differing calls of externally similar birds from adjacent regions were noted.

According to a state website, if there are any screech owls in Maine, they would be found in the extreme southern part of the state. Actually, eleven species of owls live in or visit Maine for all or a portion of the year. The great horned owl and the barred owl are the most widely distributed owls in the state.

Most owls are nocturnal predators, with hooked bills and needle-sharp talons. They have wide wings, light bodies, and feathers specially designed to allow them to silently swoop down on prey. Depending on the species, owl calls are characterized as being either a hoot, a screech, or a whistle.

The northern saw-whet owl, Aegolius acadicus, is a small owl native to North America. Saw-whet owls are one of the smallest owl species in North America. They can be found in dense thickets or conifers, often at eye level, although they can also be found some 20 feet up. Saw-whets are often in danger of being preyed upon by larger owls and raptors. Northern saw-whet owls are also migratory birds without any strict pattern.

Their habitat is coniferous forests, sometimes mixed or deciduous woods, across North Ameri­ca. Most birds nest in coniferous type forests of the North but winter in mixed or deciduous woods. They also love riparian areas because of the abundance of prey there. They live in tree cavities and old nests made by other small raptors. Some are permanent residents, while others may migrate south in winter or move down from higher elevations. Their range covers most of North America including southeastern and southcentral Alaska, southern Canada, most of the United States and the central mountains in Mexico.

They can weigh from 1.9 to 5.3 ounces, making them one of the smallest owls in North America. They are similar in size to the American robin.

The northern saw-whet owl makes a repeated tooting whistle sound. Some say they sound like a saw being sharpened on a whetstone. They usually make these sounds to find a mate, so they can be heard more often April through June when they are looking for mates. Despite being more common in spring, they do vocalize year round.

The great horned owl, Bubo virginianus, also known as the tiger owl (originally derived from early naturalists’ description as the “winged tiger” or “tiger of the air”) or the hoot owl, is a large owl native to the Americas. It is an extremely adaptable bird with a vast range and is the most widely distributed true owl in the Americas. Its primary diet is rabbits and hares, rats and mice, and voles, although it freely hunts any animal it can overtake, including rodents and other small mammals, larger mid-sized mammals, birds, reptiles, amphibians, and invertebrates.

The great horned owl is generally colored for camouflage. The underparts of the species are usually light with some brown horizontal barring; the upper parts and upper wings are generally a mottled brown usually bearing heavy, complex, darker markings. All subspecies are darkly barred to some extent along the sides, as well.

The great horned owl is the second-heaviest owl in North America, after the closely related, but very different-looking snowy owl. Although the snowy owl is not common in Maine, I have seen one on two different occasions. Once on the fence post of a pasture, and the other standing in the breakdown lane on the interstate highway.

The great horned owl is heavily built, with a barrel-shaped body, a large head, and broad wings. Its size can vary considerably across its range, with populations in interior Alaska and Ontario being largest and populations in California and Texas being smallest, though those from the Yucatán Peninsula and Baja California appear to be even smaller. Adult great horned owls range in length from 17 to 25 inches, and possess a wingspan of three to five feet). Females are somewhat larger than males.[

They are distributed throughout most of North America. I once saw a great horned owl in flight ahead of us while riding a snowmobile trail in Palermo. It was after dark and I can say they are a magnificent bird.

Typically, great horned owls are highly sedentary, often capable of utilizing a single territory throughout their mature lives. Although some species such as snowy owls, northern saw-whet owls, long-eared and short-eared owls are true migrants, most North American owls are not migratory and will generally show fidelity to a single territory year around. In great horned owls, mated pairs occupy territories year-round and long-term. Territories are established and maintained through hooting, with highest activity before egg-laying and second peak in autumn when juveniles disperse Most territorial de­fense is per­form­­ed by males, but females frequently assist their partners in hooting contests with neighbors or intruders.

The barred owl, Strix varia, also known as the northern barred owl or, more informally, hoot owl, is a large species of owl.

Barred owls are brown to gray overall, with dark striping on the underside contrasted immediately above that with similarly-dark and tight vertical barring about their throat and nape. Barred owls are largely native to eastern North America, but have expanded their range to the west coast of North America where they are considered invasive. Mature forests are their preferred habitat, but they can also acclimate to various gradients of open woodlands. Their diet consists mainly of small mammals, but this species is an opportunistic predator and is known to prey upon other small vertebrates such as birds, reptiles, and amphibians, as well as a variety of invertebrates.

The barred owl is distributed throughout most of the eastern United States, as well as much of southern Canada. They are found as far northeast as much of Nova Scotia (western two-thirds), New Brunswick and in much of Québec, up to Lake Mistassini, and Ontario, up to Moosonee.

The barred owl ranges in every part of the eastern United States continuously from northernmost Maine down throughout New England, the Mid-Atlantic states, much of the Midwest, the Southeast United States and all of Florida. A wandering barred owl was once seen flying over Lake Michigan 30 miles from the nearest land.

The barred owl, like most owls, is largely adapted to nocturnality. Between 5 a.m. and 8 p.m., juvenile barred owls were recorded to sleep an average of 28 percent of each hour. Peak times in Minnesota were found to be right after sunset and just before dawn. Nonetheless, they are not as fully nocturnal as many owls and rank around sixth amongst 19 regular North American owl species for the regularity of their activity outside of nightfall, especially in particular circumstances such as when a rival or a human impersonator is emitting barred owls calls or whilst hunting. Often daytime activity tends to be early in the morning or around dusk but potentially at any time (overcast days being preferred).

Owls are interesting creatures. An old myth exists that owls are intelligent because they look intelligent. Well, here is the truth: The wise owl appears in everything from The Iliad to Winnie the Pooh. But, it turns out, though they’re excellent hunters, owls probably aren’t any smarter than a lot of other birds. In fact, they may be significantly worse at problem solving than other big-brained birds like crows and parrots.

Several people now have shown me photos of a large bird that is seen grazing in the fields of central Maine. I’ve seen them before, but reports of sightings have become more frequent. They would be sandhill cranes.

The sandhill crane, Antigone canadensis), is a species of large crane of North America and extreme northeastern Siberia. The common name of this bird refers to habitat like that at the Platte River, on the edge of Nebraska’s Sandhills on the American Plains. This is the most important stopover area for the subspecies.

Adults are gray overall; during breeding, their plumage is usually much worn and stained, particularly in the migratory populations, and looks nearly ochre. The average weight of the larger males is 10 pounds, while the average weight of females is just under 9 pounds. Sandhill cranes have red foreheads, white cheeks, and long, dark, pointed bills. In flight, their long, dark legs trail behind, and their long necks keep straight. Immature birds have reddish-brown upperparts and gray underparts. The sexes look alike. Sizes vary among the different subspecies; the average height of these birds is around to feet, seven inches, to four feet, six inches. Their wing chords are typically 16.5 – 23.6 inches, tails are 3.9 – 10.4 inches.

These cranes frequently give a loud, trumpeting call that suggests a rolled “r” in the throat, and they can be heard from a long distance. Mated pairs of cranes engage in “unison calling”. The cranes stand close together, calling in a synchronized and complex duet. The female makes two calls for every one from the male.

Sandhill cranes’ large wingspans, typically five feet, five inches to seven feet, seven inches, make them very skilled sflyers, similar in style to hawks and eagles. Using thermals to obtain lift, they can stay aloft for many hours, requiring only occasional flapping of their wings, thus expending little energy. Migratory flocks contain hundreds of birds, and can create clear outlines of the normally invisible rising columns of air (thermals) they ride.

Sandhill cranes fly south for the winter. In their wintering areas, they form flocks over 10,000. One place this happens is at Bosque del Apache National Wildlife Refuge, south of Albuquerque, New Mexico. An annual Sandhill Crane Festival is held there in November.

Sandhill cranes have one of the longest fossil histories of any extant bird. A 10-million-year-old crane fossil from Nebraska is said to be of this species, but this may be from a prehistoric relative or the direct ancestor of sandhill cranes and not belong in the genus. The oldest unequivocal sandhill crane fossil is 2.5 million years old, older by half than the earliest remains of most living species of birds

Sandhill cranes are fairly social birds that usually live in pairs or family groups through the year. During migration and winter, unrelated cranes come together to form “survival groups” that forage and roost together. Such groups often congregate at migration and winter sites, sometimes in the thousands.

Sandhill cranes are mainly herbivorous, but eat various types of food, depending on availability. They often feed with their bills down to the ground as they root around for seeds and other foods, in shallow wetlands with vegetation or various upland habitats. Cranes readily eat cultivated foods such as corn, wheat, cottonseed, and sorghum. Waste corn is useful to cranes preparing for migration, providing them with nutrients for the long journey. Among northern races of sandhill cranes, the diet is most varied, especially among breeding birds. They variously feed on berries, small mammals, insects, snails, reptiles, and amphibians.

Sandhill cranes raise one brood per year. In nonmigratory populations, laying begins between December and August. In migratory populations, laying usually begins in April or May. Both members of a breeding pair build the nest using plant material from the surrounding area. Nest sites are usually marshes, bogs, or swales, though occasionally on dry land. Females lay one to three (usually two) oval, dull brown eggs with reddish markings. Both parents incubate the eggs for about 30 days. The chicks are precocial; they hatch covered in down, with their eyes open, and able to leave the nest within a day. The parents brood the chicks for up to three weeks after hatching, feeding them intensively for the first few weeks, then gradually less frequently until they reach independence at 9 to 10 months old.

As a conspicuous ground-dwelling species, sandhill cranes are at risk from predators, which are probably the main source of mortality. Mammals such as foxes, raccoons, coyotes, wolves, cougars, bobcats, and lynx hunt them given any opportunity, the first three mainly hunting large numbers of young cranes, the latter four types more rarely taking full-grown cranes in ambush excepting the prolific bobcat. Corvids, such as ravens and crows, gulls, and smaller raptors such as hawks (largely northern harriers or red-tailed hawks) feed on young cranes and eggs.

Cranes of all ages are hunted by both North American species of eagles. Mainly chicks and possibly a few adults may be preyed on by great horned owls and even the much smaller peregrine falcons has successfully killed a 6.8-pound adult sandhill crane in a stoop.

Sandhill cranes defend themselves and their young from aerial predators by jumping and kicking. Actively brooding adults are more likely to react aggressively to potential predators to defend their chicks than wintering birds, which most often normally try to evade attacks on foot or in flight. For land predators, they move forward, often hissing, with their wings open and bills pointed. If the predator persists, the crane stabs with its bill (which is powerful enough to pierce the skull of a small carnivore) and kicks.

In the 20th century, sandhill cranes were generally extirpated east of the Mississippi River. Although sandhill cranes are not considered threatened as a species. Resident populations, not migratory birds, cannot choose secure breeding habitat. Many subpopulations were destroyed by hunting or habitat change. Their desirability as a delicious game bird brought them the nickname of “Rib-eye of the sky” by a small group of modern hunters. The greater sandhill crane proper initially suffered most; by 1940, probably fewer than 1,000 birds remained. Populations have since increased greatly again. At nearly 100,000, they are still fewer than the lesser sandhill crane, which, at about 400,000 individuals, is the most plentiful crane alive today.

Some migratory populations of sandhill cranes face population threats due to interspecies competition with snow geese. duced offspring for annual releases into the refuge.

So, it is fair to summize that although they were generally extirpated east of the Mississippi River, they are making a comeback, as frequent sightings in the central Maine area are not uncommon.
