A face you got to adore

 The mid-day of the week is named for the Norse God, Odin. He was also known as Woden or Wotan. Unlike many of the other days of the week, this day did not correspond roughly with the Roman designation for the day. (The Roman’s named Wednesday for the Messenger God – Mercury – In Romanian, the day is still known as miercuri). The early Scandanavians and Germans believed that Odin was the chief god of Asgard and as such deserved to have a day of the week named for him. The Anglo-Saxons used the word, Wodnesdaeg.

Wednesday is often referred to as “hump day” because of its position as the middle day of the work week. If the work week were a hill, then Wednesday would be the crest. It is all down hill from there. (Whether the down hill ride is a coast or a descent into a swamp is left to the individual.)

Great weather, mild and sun have made the beginning of November a wonderful treat for many. Myself included, now the shoulder is nearly healed have been ebiking the Harbourfront Trail, Burlington Harbour into Cootes Pardise

and Grindstone Creek while this weather attracts many others also. As site coordinator at pics4twitts I am pleased to share the images with you.

Endangered Spring Migration It’s All About Timing

Just as scientists are beginning to answer basic questions about migration, many migratory birds and other animals are in trouble

Are you starting to see some of your favorite birds come back from their wintering grounds? As the seasons change, many bird species come and go in the natural phenomenon of migration. Today, scientists are just beginning to answer some of the most basic questions about migration. But a shadow hangs over their research: Many migratory birds—and other migratory animals–are in trouble.

MIGRATION BASICS

Spring Migration begins

Migration all year

What is migration? Many creatures wander, but only some are true migrants. Most biologists define migration as repeated seasonal movement between breeding and non-breeding grounds by the same individuals.

How far do birds migrate? Thanks to tracking devices, we now know the astounding distances that some migrating species travel. For sheer distance, nothing beats migrating birds. Sooty shearwaters astonished scientists by flying more than 40,000 miles in a loop from New Zealand to Chile, Japan, Alaska and California before a trans-Pacific trip back to New Zealand. The birds averaged more than 200 miles per day for 200 days.

Longest Known Non-stop Bird Flight: The real migration champ was a bar-tailed godwit that flew 6,340 miles nonstop between New Zealand and North Korea, where it rested briefly before continuing nearly a thousand additional miles to its breeding grounds in Alaska.

HOW DO BIRDS FIND THEIR WAY?

Migratory Birds

There are a range of techniques migrating birds use to navigate:

* Earth’s magnetic field: This was discovered by a series of experiments in the mid-1970s which reversed magnetic fields around songbirds, triggering them to fly the wrong direction. It is now known that some 50 species including birds follow magnetic pathways.
*Circadian clocks: innate temporal rhythms in the biochemical, physiological or behavioral processes of all living things, from plants to birds
*Internal compasses: Using the sun or stars as a compass to determine direction
*Smells: Some birds, including pigeons, use olfactory clues to find their way.
*Geographical features such as mountain ranges and coastlines. Most migrants seem to rely on a combination of these techniques depending on conditions.

WHY SCIENTISTS NEED TO UNDERSTAND MIGRATION
“The nonbreeding season drives a lot of what happens during rest of the annual cycle,” says Peter Marra, a research scientist at the Smithsonian Migratory Bird Center at the National Zoo. That cycle’s middle stages—the actual travel—remain terra incognita to scientists. The sheer number of habitats used at different points during migration presents a formidable challenge to conserving migratory birds.

NEW TECHNOLOGIES TO STUDY MIGRATION
The recently announced ICARUS Initiative will launch a satellite devoted to migratory animals and develop tiny, powerful transmitters that will allow researchers to follow creatures as small as insects across broad stretches of time and space.

WHAT ARE THE THREATS TO MIGRATORY BIRDS?

The sights and sounds

*Habitat loss and degradation. The habitats of migratory species nearly everywhere are under pressure from deforestation, farming and expanding human populations. Human-made obstacles also hinder travel. In many cities, skyscrapers, for example, kill migratory songbirds.
* Global warming. Researchers are reporting new behaviors among migratory animals worldwide that may stem from changing climate—shifts in breeding ranges, mistiming of cues and departures, for example. “Since the wintering habitats are changing at different rates than more northerly habitats, things can get really of out sync,” says the Smithsonian’s Marra.

Out of whack: In the Netherlands, some populations of pied flycatcher have crashed because the birds are arriving from African wintering grounds too late to feast on a once predictable bounty of caterpillars. Higher springtime temperatures in Europe are causing the insects to hatch earlier than they once did.

CAN MIGRANTS ADAPT?

No one knows. Recently, some birds have shown flexibility by changing routes or timing or breeding sites in response to new environmental conditions. In the Midwest, for instance, ducks are arriving later in the fall and resting longer before continuing south, perhaps in response to higher temperatures.

Along the east coast of Massachusetts, where temperatures are rising and the insects on which birds feed on hatching sooner, 8 of 32 migratory songbirds looked at have begun arriving earlier from their wintering grounds—primarily species that winter in the southern United States as opposed to farther away in the Tropics.

“But I think it would be dangerous to assume that all species can adapt,” says Princeton University ecologist David Wilcove. As Wilcove writes in his book No Way Home: The Decline of the World’s Great Animal Migrations, “The irony is that just as the phenomenon of migration is slipping away, we are entering a golden age for studying it.”

Spring Migration: It’s All About Timing

Timing and luck

From January to June, each migratory species has its own special time to return to summer breeding grounds
Somewhere in North America, there is probably some kind of migratory movement of birds every day. But spring migration—the mass movement of birds toward their breeding grounds—happens with predictable timing each year. The precise local timing varies, of course, with latitude and elevation. “Early spring” might mean early February in the southernmost states, late March or early April in the north, or even May in the far north and high mountains.

Mass Migrations

Among the first groups of birds to move north are waterfowl: ducks, geese, and swans may begin migrating as soon as frozen lakes and marshes start to thaw. Even in the northern Provinces, flocks of waterfowl may arrive in late February. Also on the move this early are some species that migrate mostly within North America, spending the winter as far north as they can. They include killdeer and red-winged blackbirds.

Some birds of prey also start to migrate in early spring. Bald eagles, rough-legged hawks and red-shouldered hawks are actively moving north even while wintry conditions still prevail.

Other surprisingly early migrants include purple martins, returning from South America and reaching Florida and Texas by late January and making it to northern states by the end of March.

Blue heron nesting zone

Many native sparrows tend to be early migrants, with large numbers moving in southern states in March and in northern states by early April. Kinglets and sapsuckers are in this moderately early wave as well. And most blackbirds move north during the first half of the spring.

 

Shorebirds (sandpipers, plovers and their relatives) have a protracted migration, with some species represented among the earliest and latest migrants. Pectoral sandpipers and American golden-plovers, wintering in South America, come back to southern provinces by the end of February and reach northern provinces by March. Many other species migrate later, with peak passage in most areas during April and May. Long-distance migrants that winter in southern South America, white-rumped sandpipers peak in  central Canada and  United States in late May or early June.

Southern Ontario

 

The great northward flood of songbirds that have wintered in the tropics—including warblers, tanagers, buntings, grosbeaks, orioles, vireos and thrushes—occurs primarily during April and May, filling North American woodlands with color, song and activity. For many birders, warblers are particular favorites; there are several places in the country where you can see more than 30 species of these tiny, colorful gems during the course of the season.

Deer Migration Huge

By early June, aside from a few shorebirds and straggling songbirds, spring migration is over across most of North America. This is when birders turn their attention to local nesting species—and get ready to watch for the first of the fall migrants, which in some areas start showing up by early July.
