The Corvids Literature Database (CLD) is online since spring 2006. Its aim is to record all known publications (citation format) about Crows, Ravens, Jays, and Magpies worldwide. Several thousand papers about Corvids can be found by using powerful literature search engines. But none of them is able to handle crow-specific search keys, like for example "Show me all papers with information about Nesting of the Black-billed Magpie". A few cited specimens can already be found at GBIF or museum websites. The database provides specimens and observations of Corvids found in published papers of the Corvids Literature Database.
