Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

Research team identifies genetic structure of painted bunting

A research team has identified the genetic structure of the painted bunting, a neotropical migratory songbird, using microsatellite DNA and single nucleotide polymorphisms to develop high-resolution markers. Using this information, the team can differentiate between individual birds breeding in different Oklahoma populations and across the U.S., as well as between the eastern and western painted buntings, and identify the species pattern of migration and population of origin. The team is working to better understand why certain painted bunting populations are declining. The painted bunting breeds primarily in the U.S. during the summer and migrates to Mexico, Central America, southern Florida and the Caribbean over the winter. Male painted buntings are brightly colored, which makes them highly sought after as pets, particularly in Mexico, Central America and Europe. Pet market birds examined for the study are most likely from the central breeding population in the U.S.
