Christmas Bird Count: Circle history report request
This site is a relic of an earlier stage in the development
of the Christmas Bird Count Database. For the current
version, see the National Audubon Society's
Christmas Bird Count pages.
- This page now includes data from New Mexico through
the latest CBC. Data from all other states goes only through
- Because I assume this page will be used mainly by New Mexico
records workers, all bird names are lumped assuming a
New Mexico locale, e.g., all Rufous-sided Towhee records
are assumed to be for Spotted Towhee. If this inconveniences
you, please let me know and I'll add a feature to disable
this name lumping.
You can use this page to request a report summarizing the
records from a single CBC circle. The taxonomy used is of the
Forty-third supplement to the American Ornithologists'
Union Check-List of North American Birds, published in 2002.
`Index to Christmas Bird Counts' to find the lat-long coordinates of the circle.
Jot down these coordinates (or print the pages for your states or
provinces of interest).
Note: Some circle have changed names or
moved their centers over the years. If the center has
shifted, note all the different coordinates it has used.
For example, the Clayton, NM count has used two different
centers, 3630 10313 and 3633 10315.
For information about the index page, see
`Christmas Bird Count: Using the index to counts'.
See also the
experimental count index, which presents the same information
in a more attractive form. The author plans to enhance this
index eventually so that you can click on the name of a circle
to get the historical report.
- Return to this page and enter the coordinates in the fields below.
Enter the four-digit latitude (as ddmm, where
dd=degrees and mm=minutes) in the first field,
and the five-digit latitude (dddmm) in the second.
(If there are multiple centers, enter the other coordinates
on the successive lines.)
- The default format uses 8 data columns per line. You may
wish to adjust this value so that the report will fit on your screen.
- Click on the Generate CBC Report button. Please be patient,
especially for circles with a long history. Some reports may take
several minutes to generate, not counting the time required to
download the report.
For a discussion of how to read the report, see
`Interpreting the CBC circle history report'.
