Look up bird species by 4-letter alpha code or common name.
Four-letter alpha codes are a quick shorthand for referring to North American bird species and vagrants. But sometimes they can be overwhelming.
Goldeneye lets you search by alpha code or species name to look up:
- alpha codes
- common names
- species with potentially confusing alpha codes
- codes that are not in use because of conflicts (e.g. PRWA)
Goldeneye is also available as a website: http://alphacodes.net
Goldeneye supports all species, subspecies, species complexes, and named hybrids included in the Bird Banding Laboratory (BBL) and Institute of Bird Population's (IBP) alpha code lists. When the authorities use different codes for the same species, the other codes are indicated in the listing. IBP codes are preferentially listed first everywhere except for BBL-specific listings (e.g. the listing for "CAGO," a BBL-only code)

- (2018-01-18) Jerald Reb: Goldeneye is an awesome tool that makes finding the correct alpha code quick and easy! Previously I would have to google search an unfamiliar code and spend five minutes searching for it; now I can do that in seconds!
- (2018-01-10) Santi Tabares Erices: SO much better than searching up the code when I couldn't remember. Quick and convenient, plus showing confusion species is super helpful as well!
- (2017-11-28) Ben Meredyk: MUCH better in every way than searching up a PDF. Speedy and elegant. I love it.
- (2017-11-28) Fyn Kynd: So quick and easy! Previously, if I ever couldn't remember a code, I would have to go to a PDF of all the codes and Ctrl + Ctrl F... this is so much better!
- (2017-11-28) Bryan Calk: Ever needed to know what the heck your birding friends mean when they say they saw a BTYW land on a ROYT? Here's your quick, easy, and elegant solution.
- (2017-11-28) L M: A great idea! I wanted to find a website or something like this, but a chrome extension is a much better way of doing it. It's fast, easy and compact. I love that you can search both ways, putting the species name, or the 4 letter code. Another great feature is that it shows similar names that could be confused with the one you searched.
- (2017-11-28) Emma Schneider: Absolutely amazing. I don't know many alpha codes, so I'm certain that this is going to help me. It's fast and accurate, and it's just a great thing to have for searching up alpha codes quickly and effectively.
- (2017-11-28) Ryan Andrews: Fast, accurate, effective. Perfect for searching up codes you don't recognize quickly.
