Chicagoers enjoy the sights and sounds of sandhill cranes, which have recently moved overhead as large, noisy birds fly south.

Bird lovers in the area are eager to expect an annual flyover, but this year’s move has been a source of anxiety for regular crane observers.

Who to check Weekly bird counts provided by staff in the Jasper Pulaski Fish and Wildlife Area of ​​Indiana — A major resting place for cranes along the eastern flyway before the last push to Florida — the number noticed was dramatically less than expected. Reference: The number of weeks in 2020 has steadily increased from 11,255 in early November to over 16,000 on 17 November. By November 2, less than 2,000 sandhill cranes had arrived at Jasper Plaskey in 2021, and by November 18, only 4,452 had arrived at the scene. ..

Given that the Midwestern subspecies of the sandhill crane was once reduced to only 20 nesting pairs, the threat of a serious population decline came to mind.

After all, the bird was simply procrastination.

On Tuesday, Jasper Plaskey reported 28,652 cranes. He can recall that this is the largest increase for Nathaniel Miller, the Conservation Director of Audubon’s Great Lakes.

“I’m glad to see these numbers,” said reassuring Miller, who theorized that warm autumn weather was likely to have played a role in delaying the departure of cranes from the northern breeding grounds.

“The migration of birds is not yet well understood, but we know they are given clues by the weather,” he said.

Indeed, the crane has Gradually arrived at Jasper Plus Key According to Miller, this year was due to rising temperatures due to climate change, but not as significantly as this year.

Sandhill cranes have proven to be elastic, but changes in mobility habits can outweigh their ability to adjust, he said. For example, wetland-loving birds may travel further north in the summer, chasing cool temperatures and encounter forest areas that do not suit their needs.

It’s an ever-growing and more assertive warning alert, Miller said, lending urgency to legislation as proposed. Growing climate solution lawThis will allow farmers to adopt practices such as maintaining or restoring wetlands on land that are currently poorly provided to wildlife in terms of food and shelter.

“Most of our land is privately owned, so we need to be able to work on these lands,” Miller said.

Now here, Miller encouraged people to take in the sight of tens of thousands of sandhill cranes with Jasper Plus Key. This is a gathering that he likened to a bird festival.

He said the crane is a very sociable bird and is always talking. They form a close family unit that travels together (unlike Chicago’s beloved Prover), hang out for weeks at Jasper Plus Key, and make friends just like humans make bonds with their neighbors. According to Miller, the crane has the feeling that it may even decide when to leave Jasper Pluskey based on when its peers are ready to go.

He said they are such an incredible seed and a major motivational factor in driving conservation efforts.

“Birds are durable, if you give them a chance to fight,” Miller said.
