Bird-DB: A database for annotated bird song sequences

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. © 2015 Elsevier B.V.
