Each species is slightly different with some feeding, some grooming and some snuggling. But can we call it love? Join us for this pre-recorded program to discuss bird courtship.”

Michelle Campanis, education coordinator at the University of Tennessee Arboretum, and naturalist Stephen Lyn Bales will discuss aspects of avian pair bonding in a pre-recorded program for February’s First Thursday Nature Supper Club, the press release said.

President Joe Biden will appoint Merlin Theodore of Oak Ridge National Laboratory to the National Science Board, the White House said in an announcement last week.

Theodore is the first full-time researcher from a national laboratory to serve on the National Science Board, the governing board for the National Science Foundation, according to ORNL.

“Merlin’s appointment to the National Science Board is indicative of her accomplishments as a researcher, her contributions to national missions, and her advocacy for women and minorities in science,” said interim ORNL Director Jeff Smith.

Theodore is one of eight new board members. The National Science Board is made up of 25 members appointed by the president, and they serve six-year terms.

The National Science Board pursues the goals and function of the NSF, including the duty to “recommend and encourage the pursuit of national policies for the promotion of research and education in science and engineering,” according to the White House news release.
