The preferred habitats of Common Grackles include open shrublands, forest edges, and marshland edges with shrubs. BCN trends indicate a significant moderate increase. Sizeable populations in urban areas and agricultural areas are poorly represented by BCN Survey point counts, which are usually located in preserved areas. Photo: © Gregg Williams
