Topic: Do you chase rare birds that accidentally occur in our area outside of their normal migration range? If so, you enjoy finding vagrant birds, a phenomenon many Marin County birders pursue at the Outer Point within Point Reyes National Seashore and other California coastal areas. This presentation will highlight the reasons for vagrancy in birds, noting how birds navigate during migration and reasons for their orientation errors that result in their unexpected presence primarily from mid-August through October in west Marin County. In addition, the discovery of vagrancy at the Outer Point by Rich Stallcup and David DeSante will be discussed, along with the role vagrancy may play in colonization and eventual speciation of birds.
