COMMON GRACKLE
Preferred habitats include open shrublands, forest edges, and marshland edges with shrubs. BCN trends, although not statistically significant, may indicate that this species is fairly stable in our area. 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 |
