Sandhill Cranes Are On the Move!

"Spring swoops onto the prairie on a brisk, bold breeze. A warbling, trumpeting, chirping noise gets louder and louder. Soon hundreds of thousands of sandhill cranes fill the sky. They're on the move!" ~ On the Move: Mass Migrations by Scotti Cohn

It's that time of year again -- the time when hundreds of thousands of sandhill cranes head for Nebraska from their wintering grounds in Texas, New Mexico, Arizona and Chihuahua, Mexico. Here's an informative article with great photos: _500,000 Cranes Are Headed for Nebraska in One of Earth’s Greatest Migrations_

A report that aired on NBC News: _Thousands of cranes arrived in Kearney, Neb., stunning birdwatchers with their beauty._

Get Warmed Up for the Salamanders!

"Spring paints the forest in fresh shades of purple, yellow, and green. Warm rain falls in drips and drops on the cold ground. Spotted salamanders crawl out of their underground homes after dark. . . This is their big night, and soon they are on the move." ~ On the Move: Mass Migrations by Scotti Cohn

The spring migration of the spotted salamander usually occurs after a hard rain and temperatures are around 55 degrees Fahrenheit, especially after a week or so of warmer temperatures to help warm the ground. This year, the salamanders at Ruffner Mountain Nature Preserve in Alabama got moving near the end of last month. Further north, certain species of salamanders, frogs, and toads are just now gearing up for the event.

Salamanders make a big difference in ecosystems because of the amount of insects they consume, and they are prey for birds and small mammals. Here is an interesting article about research and studies that are being done about salamanders: Ohio State researcher discusses salmander study in the county.

In some areas, roads are closed during the period of time that salamanders are traveling to their breeding ground. Crossing brigades are organized to protect the salamanders. Some communities plan special activities during which people can view the migration firsthand and learn more about why it takes place. For example, in Arcadia, Massachusetts, "Big Night" hikes and activities are scheduled for March 29 of this year: Arcadia's Big Night.

Bald Eagles On the Move!

In winter, bald eagles that live in certain areas of North America have to leave their nesting areas because those areas freeze up, and the birds cannot find enough food to survive. For example, each year, hundreds of bald eagles overwinter in the Red Wing and Wabasha areas near the Mississippi River in Minnesota. The best viewing opportunities there are in December through March.

By January, many eagles that live in states and provinces to the north have traveled hundreds or thousands of miles to join hundreds of year-round resident bald eagles in California. On some midwinter statewide surveys, more than 1,000 bald eagles have been counted in California. The largest concentration of wintering eagles is found in the Klamath Basin, on the California-Oregon border. Best viewing opportunities are December through March.

 

The start of the new year in Illinois means bald eagle watching season throughout the state. The eagles fly in by the thousands and stay through March. One way to see these birds in their natural habitat is by going on a Bald Eagle Safari in Rock Island.

 

The Delaware River valley is another important wintering habitat for bald eagles. Depending on weather conditions, the eagles begin arriving in mid-December. By mid-March most eagles begin the return to their breeding areas located to the north. Some eagles migrate from as far away as Canada.

Here Come the Elephant Seals!

"Most of the year, northern elephant seals live alone. They swim, dive, and hunt. Come winter, they are on the move. They haul out on land, and soon the beach is covered with seals. They squawk, squeak, bellow, belch, grunt, and gurgle." (from On the Move by Scotti Cohn)

"From December through March a breeding colony of elephant seals can be observed from Elephant Seal Overlook near Chimney Rock, above beautiful Drakes Bay. The males are the first to arrive here, in December, to stake out a claim on the beach. Then pregnant females begin to arrive and soon give birth to a single pup. Subadult and juvenile animals arrive and the colony can number close to one hundred animals.  Point Reyes National Seashore is one of only about a dozen sites where northern elephant seals breed worldwide."

Time for the Tundra Buggy Cam!

It's 32 degrees Fahrenheit and snowing today "way up north" in Manitoba, Canada, and the polar bears are back! They are gathering along the Hudson Bay to wait for ice to form. At this time, the bears are in a state known as "walking hibernation."

You can keep an eye on them via the Tundra Buggy Lodge camera located in Churchill, Canada. Best viewing hours are 10:00am - 4:00pm, Central Time. You can help scientists by simply taking a snapshot!

Snakes Alive!

"It's the end of a sunny autumn day in the forest. . . Every year at this time, snakes that live in cold climates travel to dens to spend the winter. They often return to the same den each year, and large groups of snakes may share the same den." ~ On the Move

Monarch Butterflies on the Move!

"Up north, the autumn air is chilly. Monarch butterflies flutter their brilliant orange and gold wings. Soon they are on the move. More and more monarchs join the flight until tens of millions of monarchs are flying south together...

copyright Susan Detwiler

...These butterflies have not made this trip before. Somehow they know to take the same route as the monarchs who lived before them. They even stop to rest in the same places. Once they reach their southern home, the monarchs will sleep for much of the winter." (from On the Move by Scotti Cohn)
