Are you looking for a way to speed up your field notes so you can focus on actually looking at birds? Do you see birders using codes for birds on listservs and want to look them up? Do you want to enter your eBird checklists faster?

Alpha codes are four letter abbreviations assigned to bird species as a quick way to refer to them. These codes are commonly used in field notes to quickly record sightings and other situations where writing down the entire species name is impractical. This app allows you to search and learn the alpha codes created using the Pyle and DeSante (2003) system which defines alpha codes for all 2078 species recorded in the AOU (American Ornithologists’ Union) area. You can quickly search by either the birds name or by the alpha code.

Easy Banding codes / 4 letter codes

Next time you want to make sure you’re not crazy, that there isn’t anything normally called a YHBB or a CEWA, you can check here instantly. One thing well.

Terrific app, needs taxonomic update

I rely on this app (ver. 2.2) as the quickest way to search for band codes and proper scientific names but it is out-of-date. It could benefit from adding new US birds (accepted vagrants) and a taxonomy update, reflecting splits:
- Western Scrub-Jay to California and Woodhouse’s in 2016;
- Clapper Rail to Clapper and Ridgway’s in 2014;
- genus split for the North American cormorants in 2021.
- et al.
