Their music is for the birds -- and Still on the Hill is proud to make it. Kelly and Donna Mulhollan, known for their prolific catalog of Ozark music, will perform their "Words on Birds" set 6 p.m. May 7 at the Bailey Center at Mount Sequoyah in Fayetteville. It's a fundraising event for Arkansas Audubon Society Halberg Ecology Camp and Northsong Wild Bird Rehabilitation, and the evening will also include a silent auction for the needle-felted birds Donna started creating during their pandemic hiatus.
