That's a helpful site, although the list includes only "land birds," so
no estimates for ducks, geese, gulls, rails, pelicans, cormorants, etc.
But it lists Red-winged Blackbird as the third most abundant land bird
in North America. The top 20 are below.

One source you can peruse is the Partners In Flight Database 

 

http://www.rmbo.org/pif_db/laped/default.aspx

 

 

Most of the estimates are based on BBS data, but at least they're a
starting point for getting a sense of the most common species in North
America.

 

Have fun.

Bill -

 

Just to set the record straight, I have participated in the annual CBC
at Clarence Cannon each year for a number of years, and I DO know that
counting birds is NOT easy (although I don't count birds in the same
small area 3-4 times/month). 

 

I didn't intend to imply such a thing -- just thinking that maybe one or
more of the top birding organizations had compiled various counts from
across the nation to come up with some educated nationwide "estimates".

 

Thanks for your comments.

NO ONE counts the common ones completely. These are estimates. The
closest "estimates" might be from the Breeding Bird Survey. This survey
probably actually counts birds on a small fraction of a percent of all
the habitat in North America. As one example of how these are estimates,
there is ONE BBS route in the entire Missouri Bootheel. I conduct that
one, and usually count around 400 RWBL. I have little doubt there are
upwards of half a million or more in the entire Bootheel. A hundred bird
counters could drive themselves insane and still not get a complete
count of them. Then, there is error associated with these estimates. Did
the "representative" areas get counted? Were the observers good at
counting? Was the weather ideal for counting? How detectable were the
birds? All these and many other factors mean that estimates have error.

 

"Threatened" and "endangered" are legal definitions at the federal
level, and a species gets on those lists by petition. these petitions
are accepted oftentimes based on "best professional judgment". Some
counts of these species are very accurate (Whooping Cranes are large and
visible and very rare, and a complete count is obtained every year.)
Many of the Hawaiian forest birds, on the other hand, are in
poorly-accessed areas, in trees, not very visible, etc. Many of the
"counts" of these are ballpark estimates as a result (300-400, for
example).

 

The oft-repeated statement that Red-winged Blackbirds are the most
common bird in North America is not really based on any hard numbers.
Rather, it is based on estimates from small areas, relative abundance of
Red-wings (that is, they are often the most common species in many, many
habitats), their wide distribution, and counts done by USDA folks of
winter flocks in many areas. That being said, who knows? They may NOT be
the most abundant species in North America, but my money is on them.

 

If you think counting birds is easy, try it in a small area, and repeat
it 3-4 times over a month. You will be amazed at the variation in your
counts!

	Bill -

	 

	I totally agree with your synopsis, however, the question is --
does a reputable birding organization publish a list of "estimated"
total North America bird counts?

	 

	One would think, as these organizations are "counting" the
threatened and/or endangered species, they would also "count" the rest
of the birds (if they didn't count the others, how would they know which
ones were most threatened or endangered?).

	I would submit that Snow Geese are relatively completely counted
by CBC, because the circles often center on refuges. Red-wings are
undoubtedly less thoroughly counted by CBCs. The Breeding Bird Surveys
may give a better picture, but there are a lot of assumptions there,
too.

	 

	Of course, NO ONE has complete counts for any common
species--only the rare, threatened or endangered ones (sometimes).

		MO-Birders -

		 

		I am trying to resolve a question about N.A. bird
populations and I hope someone on MO-Birds can assist me.

		 

		I was discussing bird populations with my brother and I
mentioned that I believed the most common bird in North America was the
Red-winged Blackbired (a statistic I've believed was true for some
time).  He came back with a list from the most recent CBC, which shows
the Snow Goose at #1.
