Katie Percy and Lauren Solomon, both with the Audubon Society, trap a prothonotary warbler to gather information about them in the Bluebonnet Swamp. Since two of their subjects have migrated back to Baton Rouge after summering in Latin America. Last year, the Audubon Society tagged a bunch of warblers with tracking devices to help figure out why their numbers are decreasing.

The Audubon Society is asking for volunteers to help contribute to science over the holidays.

In the coming weeks, the conservation organization will be hosting the annual Christmas Bird Count, which for 117 years has helped researchers track bird populations across the Western Hemisphere, the Audubon Society said in a news release.

Several events have been scheduled throughout south Louisiana, including a Dec. 30 outing in the Baton Rouge area. There also are events in St. Tammany Parish, Plaquemines Parish, Grand Isle, Thibodaux, Cheneyville and other places.

Audubon expects more than 72,000 volunteers to collect data at more than 2,500 locations, creating detailed survey data that scientists couldn't collect on their own, the release states.

"To date over 200 peer-reviewed articles have resulted from analysis done with Christmas Bird Count data," the organization wrote. "Bird-related community science efforts are also critical to understanding how birds are responding to a changing climate.

"This documentation is what enabled Audubon scientists to discover that 314 species of North American birds are threatened by global warming as reported in Audubon’s groundbreaking Birds and Climate Change Study."
