Frequently Asked Questions

What are the system requirements for BNA?

We recommend you use one of the following browsers to access BNA: Internet Explorer, Chrome, Firefox or Safari. The minimum version required for Internet Explorer is Version 10.0. Users must have cookies and JavaScript enabled for full functionality.

I cannot seem to find a particular species. Why?

Please keep in mind that BNA only includes the regularly breeding birds of Canada and the United States (including Hawaii). Birds that pass through this region, just as vagrants, regular migrants, or occasional breeders are not covered by BNA. For information about species found in Mexico, Central America and South America, please check our sister publication Neotropical Birds.

Can I still purchase hardcopy BNA accounts?

Yes you can; Buteo Books now owns the remaining inventory of the paper copies of the Birds of North America single species accounts. Please call Buteo Books at 800-722-2460 or email customerservice@buteobooks.com for more information.

How do I cite the BNA database or an individual species account from BNA?

To cite the BNA database as a whole, you can use one of two formats:

The Birds of North America (P. Rodewald, Ed.). Ithaca: Cornell Laboratory of Ornithology; Retrieved from The Birds of North America: https://birdsna.org; AUG 2015.

or if you need to go with more standard author/date format:

Rodewald, P. (Editor). 2015. The Birds of North America: https://birdsna.org. Cornell Laboratory of Ornithology, Ithaca, NY.

When citing a species account, give the author's name(s) and initials and the year of publication in parentheses. If the publication has been revised, use the revised date. Otherwise, use the original print date. Next list the species name followed by the site information. You may add the date you accessed the information. See the examples below.

Haig, Susan M., and Elliott-Smith, E. (2004). Piping Plover. The Birds of North America (A. Poole, Ed.) Ithaca: Cornell Laboratory of Ornithology; Retrieved November 2, 2004, from The Birds of North America: https://birdsna.org/Species-Account/bna/species/pipplo/

Marti, C. D. (1992) Barn Owl. The Birds of North America (A. Poole, Ed.) Ithaca: Cornell Laboratory of Ornithology; Retrieved from The Birds of North America: https://birdsna.org

Note: The Recommended Citation section of the accounts may contain the citation for the print version of BNA. Please use the format above instead.

What should I do if I find an error in a species account?

The BNA editorial staff welcomes your input on errors in the species accounts. We will work to correct these as quickly as possible. Please email your corrigenda to Paul Rodewald, BNA editor.

It is our goal to have all BNA species accounts continually updated, with the initial emphasis on recent species splits and accounts published early in the series. If you have updates to contribute to a species account, please email Paul Rodewald, BNA editor.

I am an AOU member and cannot access BNA through the AOU. Help!

If you are a current, paid member of the AOU, you can access BNA through the AOU proxy server. You will need your AOU login ID and password, which is the following: User name: AUK + 00 + your OSNA number (the username is case specific, make sure you begin with "AUK00" plus your OSNA number), Password: your last name, with the first letter uppercase. You will enter this login information here, at the AOU/BNA proxy server. If you have forgotten or do not know your OSNA number, you can contact the AOU business center at business@osnabirds.org. Please DO NOT try to enter your AOU login/password on the BNA's main site page, you will NOT be able to login this way.
