Bird-DB: A database for annotated bird song sequences

- We describe a database for records of bird songs annotated for phrase types.
- The database will further analysis of bird song syntax.
- The files in this database and their metadata are available for pubic download and analysis.
- A mechanism is described for uploading user-generated recordings, annotations and metadata.

Projects on the acoustic monitoring of animals in natural habitats generally face the problem of managing extensive amounts of data, both needed for - and produced by - observation or experimentation. While there are many publicly accessible databases for recordings themselves, we are aware of none for annotated song sequences. In this paper, we describe our database system of bird vocalizations and introduce our online sample repository for the community of researchers studying the syntax of bird song.
