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.
