Earth Notes: The Look of Love, for Barn Swallows

Each year barn swallows dart and swoop in summer skies to catch insects. But these flashy blue and orange aerialists aren’t on the hunt for only food. As is true with our own species, barn swallows use athletics and appearance to show off to the opposite sex.

With their distinctive forked tails, barn swallows are widespread. On multiple continents they build mud cup nests under bridges and in barns and other human structures. But their choice of mates varies from place to place.

Promotheus Solar

Flagstaff’s Southside Murdoch Community Center is about to get solar panels installed on its roof. That’s not innovative—but the way the panels are being paid for is. Thanks to 87 small-scale investors and a company named Solar Mosaic, the center will enjoy long-term energy savings without big upfront costs.

Solar Mosaic focuses on financing clean energy projects with help from what it calls the “power of the crowd.” So far the company has funded five solar projects in California and Arizona.

Earth Notes: The Desert’s Crusty Nursery

Crusty Soil

Many parts of the Colorado Plateau are covered with distinctive soil crusts. Scientists are learning more about how they aid ecosystems—especially by providing good places for plants to grow.

Soil crusts rely on tiny organisms called cyanobacteria that are good at colonizing bare soil. In cold regions, frost heaving can give a dark, pinnacled appearance to soil covered with cyanobacteria. And that complicated micro-topography is key to what comes next.

Earth Notes: Grand Canyon Weather, Right Now

A picture of the Grand Canyon on a snowy day from the southern edge.

Each year an average of 250 people are rescued from inside Grand Canyon. Many of them are hikers unprepared for the substantial temperature difference between the top of the rim and inside the canyon. Hikers can be surprised as they start with pleasant 70-degree temperatures at the top and approach a dangerous 100 degrees, or more, near the river.

Now the National Weather Service is working to address that gap in perceptions. With help from the Park Service, it installed two weather stations inside the Canyon: one at Indian Garden Campground, the other at Phantom Ranch.
