Losers: Declining and Uncertain Populations

I have been busy re-tagging all my images since it turned out that Cornell’s All About Birds site was not up-to-date on its populations trends. I realized this when I began noticing differences in their information compared with Partners in Flight. Cornell told me to rely on Partners in Flight and that they would have their site updated in January. You may have noticed also that I updated my earlier Winners page in accord with my updated tags.

Birds whose populations are declining include: American Kestrel, Baltimore Oriole, Barn Swallow, Blue Jay, Brown Thrasher, Brown-headed Cowbird, European Starlings, House Sparrow, Indigo Bunting, Little Blue Heron, Long-tailed Duck, Mallard, Northern Flicker, Northern Harrier, Northern Mockingbird, Northern Shoveler, Oak Titmouse, Red-winged Blackbird, Short-eared Owl, Song Sparrow, Western Meadowlark, and Wood Stork.

Species whose populations are uncertain are: Downy Woodpecker, Green Heron, and White-throated Sparrow. Declining and uncertain populations are not necessarily a sign that the species is threatened with extinction, since several of these species have very large populations to begin with.  Nevertheless, they bear watching.
