This database is a quantitative summary of the published literature on the diets of bird species.
This website (https://aviandiet.unc.edu) allows users to explore the most up-to-date database information, and to generate basic summaries by diet or prey item.
A developmental R package is available here for exploring, summarizing, and filtering the database in the R environment.
Note that the dietdb database object loaded with this package may be slightly out of date relative to the AvianDietDatabase.txt file in this repository.
Instructions for entering and cleaning new diet data information can be found here.
Did you find an error in the database? Do you know of a published study with quantitative diet information that is not included in our database?
