Hi Group,
Thanks to the Horicon Marsh Bird Club Newsletter, here
are some estimated populations of the five most numerous
bird species in North America.
American Robin - 310,000,000
Dark-eyed Junco - 260,000,000
Red-winged Blackbird - 190,000,000
Red-eyed Vireo - 140,000,000
White-throated Sparrow - 140,000,000
The Landbird Population Estimate Database may be the
most fantastic bird survey of the decade.
Best wishes,
Lance
