Birds of a weather migrate together

MARINE ON ST. CROIX — We may not be able to see the levels of CO2 in our atmosphere, but we can see the birds in our backyard. A presentation at the Marine Community Library on March 17 took a close look at the ways that bird behavior indicates changes in the climate, changes that aren’t always obvious in our day-to-day lives. Don Arnosti is the conservation policy director for the Izaak Walton League, which promotes conservation of the natural world. His presentation began with a demystification of climate change and the results of the U.N. Climate Change Conference that took place in Paris in 2015, and moved on to the ways that birds have been indicating the changes in global climate in your own backyard. “They’re everywhere, and they are sensitive indicators to what is going on the earth,” Arnosti said. For birds, survival is all in the timing. Arnosti said that the gradual changes won’t be too tough on short-distance migrants, such as chickadees, cardinals, waterfowl and other birds. The most alarming change is to the lifestyle of the long-distance birds, which spend their winters in tropical climates and rely on the length of the day to tell them when to return north. Unlike the short-range migrants, these birds have no idea that spring has come early, and they may return to find that some of their major food sources are no longer available. For example, neotropical warblers depend on a large caterpillar population to feed themselves and their young. “One pair of evening grosbeaks can eat up to 50,000 caterpillars during breeding season,” Arnosti said. But since the weather has warmed up sooner than these birds were expecting, those caterpillars have already retreated into cocoons, which is not a food source for the birds.

LILA students visit Mount Everest via Google Expedition, an upcoming app for Android devices.

Students ogle through goggles on Google virtual tours BY JACKIE BUSSJAEGER STAFF WRITER

FOREST LAKE — Sitting in a common area at Lakes International Language Academy (LILA) upper school, students gazed in wonder at the icy slopes of Mount Everest. Each student had goggles strapped to his or her face, and each was experiencing their first venture into a Google Expedition—an educational journey to the corners of the world that can’t be reached by school bus. “Expeditions is a virtual reality platform built for the classroom,” claims Google.com. The company has been offering free trials of this app to schools around the world before it becomes widely available in fall 2016. There are more than a hundred destinations to choose from. Here’s how it works: an Android device is situated horizontally in a pair of goggles that block out distractions. The destination is controlled with a tablet device, navigated by the class instructor. Students can look up, down and in every direction to view an immer
