Most Recent Update: 21 March 1997.
Warning!This is a review version of the 1996 analysis and summary.
There are still some rough edges showing, and we would appreciate hearing
your comments and suggestions!
This program allows you to display trends for
3 time intervals, by either species or region.
This program allows you to display annual indices of
abundance for any species in any region.
These are preliminary versions of the new abundance maps, estimated
over the interval 1982-1996.
These are maps of population change, based on the 1966-1995 interval.
These are maps of observed species richness and composite population change,
for all species and 12 species groupings of management interest.
These lists provide mean abundances
for all species encountered on the BBS in a state/province,
summarized by physiographic region.
This program allows you to estimate mean abundance from BBS
data for any species, at any location in the survey area. (Sorry,
no Alaska data in this yet. Maybe next week!)
These maps, based on BBS data in Alaska, are very rough.
We will update them occasionally.
This program allows you to estimate (and plot) population change
for any species, on any BBS route.
This program allows you to estimate population change for
any species and time interval, in any region covered by the BBS
This link transfers you to the species identification section,
in which is contained pictures, songs, and identification tips
of most North American Bird Species.
This link transfers you to the species information section,
that contains links to species-specific information such as life history,
identification, distribution maps, pictures, and songs.
Test your skills of identifying North American bird
songs, pictures, and breeding and wintering distributions.
