Smithsonian scientists in Minnesota to help preserve songbird species

A pair of scientists with the Smithsonian Institute Migratory Bird Center in Washington, D.C., are outfitting wood thrush birds in Minnesota with tiny backpacks in an effort to help preserve the rapidly declining songbird species, the Pioneer Press reports.

The devices the scientists are putting on the birds – located in the forests of northern Washington County – weigh less than a dime and contain "geolocator" tracking devices, which will be used to preserve the wood thrushes' habitat, the paper says. The backpacks go over the birds' hips and legs, and sit on their backs with an antenna attached to pick up a GPS signal.

One of the scientists, Calandra Stanley, tells the Pioneer Press "one of the biggest threats to migratory songbirds is forest fragmentation," and maintaining their forest habitat "is probably the biggest thing that could help migratory songbirds in Minnesota."

The scientists hope to put sensors on 25 wood thrush birds, and have tagged 14 of them so far, the Pioneer Press says.

Similar efforts to protect the wood thrush have been made in places like Kentucky, the Lewisboro Ledger reports.

According to the publication, the National Audubon Society identified the wood thrush as the priority species for conservation.

The society says the population of the songbird has declined about 50 percent since the mid-1960s.

Scientists slogging through Minnesota wetlands

An ongoing research project, the first large-scale objective measurement of wetland quality in Minnesota, is under way to size up the health of roughly 10 million acres of wetlands in the state, roughly 20 percent of Minnesota's landcover. Wetlands face a variety of threats, including agricultural development and invasive species.

Building a better beer? U of M scientist helps map barley genome

An international team that includes University of Minnesota scientist Gary Muehlbauer has mapped the genome of barley, one of the world's most important and genetically complex cereal crops, and a key beer ingredient. The researchers say the findings could lead to higher yields and a grain that can more easily handle climate change.
