Throughout the code, we use these definitions.
Bird codes are case-insensitive, and in free-field situations they may be shorter than the maximum length.
Hence, we defined a stanardized bird code as one that has been uppercased and right-padded with spaces to the maximum length. This value is typically used as a key in dictionaries for looking up bird codes.
A name in the usual order, e.g., “Little Blue Heron”.
When the English name of a kind of bird has multiple words
(counting hyphenated groups as single words), the
inverted name has the form
“generic, specific”, where the generic part is the last word and the
specific part is all the
other words. For single-word names, there is no
difference.
Here are some examples.
| Normalized name | Inverted name |
|---|---|
| Little Blue Heron | Heron, Little Blue |
| Black-crowned Night-Heron | Night-Heron, Black-crowned |
| Sora | Sora |
