body mass, fat mass and wingspan data of birds entered by a researcher,
CAFE calculates flight energetics, potential migration distances
and flight speeds. Formulas and calculations in CAFE are based
entirely upon those published in Pennycuick (1989): "Bird
Flight Performance: a Practical Calculation Manual", Oxford
University Press. Any questions regarding specific formula calculations
should be investigated there, and all publications using CAFE
should cite Pennycuick (1989) as well as CAFE. All variable names
and abbreviations have been kept as close to those used by Pennycuick
(1989) as possible.
Pennycuick (1989) included a 5.25" floppy with programs
in BASIC which performed functions similar to those of CAFE,
several improvements have been made by this rebirth. These include:
multiple record input capability
the ability to both read data from and save output to tab-delimited
files (such as those created and read by spreadsheet applications).
