Christmas Bird Count history report system | |
The Christmas Bird Count of the National Audubon Society is a unique resource for ornithological researchers: a continent-wide survey of early winter bird numbers going back to 1900. Each published census is a count of all the birds in a 15-mile-diameter circle on one day between mid-December and early January.
This document describes the implementation of a Web-based application to display a report showing the history of a given circle or combination of circles.
This system is built on top of a number of existing layers that are documented elsewhere.
All scripts are written in the Python programming language. For more information, see the main Python web site or the author's Python tutorial or Python reference guide.
pycbc: A Python interface to the Christmas Bird Count
database describes the database
that holds the raw data.
A general system for describing the kinds of birds is
presented in xnomo3: A system for
representing bird taxonomoy.
In particular, the database uses the system of six-letter
codes described here. For example, American Robin is
encoded as AMEROB, and Zone-tailed Hawk as
ZOTHAW. The linked document discusses how
each such code represents a specific taxonomic grouping.
