Patrick O’Neal (left) and Justin Char (middle), members of EnCouncil, the engineering student council, construct birdhouses April 9 in the parking lot of Uncas A. Whitaker Hall for Biomedical Engineering. Joining them is Boris Chenomordik (right) from the University of Louisville. EnCouncil members built the birdhouses alongside delegates representing engineering student councils from across the country who were in St. Louis for the National Association of Engineering Student Councils’ national conference, hosted by EnCouncil. The birdhouses will be sold at Thurtene Carnival, April 16-17 with proceeds going to WashU Build, the campus chapter of Habitat for Humanity.
