Changes In Bird Populations In East Bay Bird Populations

The Golden Gate Birder, the blog of the local Bay Area Audubon Chapter had an informative post by Bob Lewis.

He analyzed the findings of Oakland’s Christmas bird counts over the past thirty-eight years and identified which bird populations had the greatest increases and losses. The largest percentage increases were Raven, Red-shouldered Hawk, Pygmy Nuthatch, American Crow and Common Merganser.   (I have certainly seen large Raven and Crow increases in my north Berkeley flatlands neighborhood. ) The birds with the biggest losses in the Oakland bird counts were White-winged Scoter, Bonaparte’s Gull, Northern Pintail, Red Knot, and Horned Lark.
