Snobs und blue collars worker in Chicago. 6-7 Minuten.

"There are two squirrel species in Chicago, and they are very particular about where they live. Gray squirrels tend to live in ritzy neighborhoods, while fox squirrels thrive in more affordable areas. A local biologist thinks he’s finally figured out why."

Nuts about squirrels. 3/4 Stunde!

"Not much more than a century ago, in towns and cities across North America, we still hunted squirrels - for dinner! That made them rare, but now that's all changed. Squirrels are a wonderful example of nature adapting to the fast-paced urban life that dominates much of their former territory. And, yet, we pay little attention to these furry creatures that share our city parks and streets. We see them every day, scurrying around our parks looking for nuts, tearing through our backyards and fearlessly leaping through the air from tree to tree, but most of us know very little about our furry fellow urbanites. What makes them so squirrelly and do they really remember where they bury their nuts? In Nuts about Squirrels, meet the scientists who are foraging for answers. Getting inside their heads to figure out what makes them tick is no easy task, but Joel Brown from the University of Illinois at Chicago, has designed some creative experiments to do just that. He takes advantage of their passion for nuts and seeds to reveal their inner 'landscape of fear' and gives us a tour of a typical backyard from a squirrel's perspective. Perhaps Joel Brown gets some of his squirrel insider information from watching Rowdy - his 'pet' squirrel - "a rehabilitation failure." Whatever it is he's inspired hundreds to become citizen squirrel scientists who are building a detailed picture of North America's squirrels. The Nature of Things is hosted by the world-renowned geneticist and environmentalist, David Suzuki, the program is in its 55th season, a landmark by any standard."

ist zweimal der gleiche Link. Hat einmal CTRL+C nicht geklappt.

Argh....

Irgendwie funktionieren die beiden ersten Links sowieso nicht so, wie sie sollten. Hier ist noch mal der erste.

Ich hatte die beiden Videos schon vor längerer Zeit gefunden und sie mir angeschaut. Interessante Ergebnisse.
