“They start coming in on Valentine’s Day, peak on Saint Patrick’s Day, and are gone on Tax Day.” That’s what experienced observers say about the thousands of Sandhill Cranes that descend every year upon the Big Bend, the part of the Platte River between Grand Island and Lexington, Nebraska. The annual spectacle is the subject of a feature article in the April 2015 issue of BirdWatching.
Scientists say the birds are members of the Mid-Continent Population. They spend the winter in southeastern Arizona, New Mexico, Texas, and central and northern Mexico and breed in Canada and northwestern Minnesota and as far away as western Alaska and southeastern Asia.
Following a millennia-old route, the cranes stop along the Platte — a winding thread of riparian habitat in what was once tallgrass prairie but is now a sea of corn — to rest and build up fat reserves for the next stage of their trip. The birds even sleep in the river. Broad and shallow, it braids through sandbars and islets, providing safe overnight accommodations.
Watching the Sandhills come to the river in the evening is a delight. Every birder should experience it at least once.
When to see them
The cranes depart their wintering areas between late February and early March and arrive at the North Platte and Platte River valleys in late February. Numbers peak from mid- to late March.
The birds depart Nebraska from early to mid-April and arrive at nesting areas in Manitoba in late April, in Alaska from early to mid-May, and in Siberia no sooner than early May.
Other cranes to look for
Whooping Cranes are occasionally seen with Nebraska’s Sandhill Cranes, but they’re not the only rare cranes to watch for.
Common Crane, a Eurasian species, has also been found — and so regularly that it’s now thought to be annual. The state’s last report was in April 2014, when one was discovered in a group of 1,000 Sandhills near Elm Creek, a town between Kearney and Lexington.
Birders reported individual Common Cranes eight months later in west Texas and New Mexico, adding fuel to speculation that Common Cranes spotted in interior North America probably joined populations of Lesser Sandhills on their breeding grounds in northeastern Asia and then accompanied them to and from their wintering areas.
