The Internet Bird Collection (IBC) is a non-profit endeavour with the ultimate goal of disseminating knowledge about the world's avifauna. It is an on-line audiovisual library of the world's birds that is available to the general public free of charge. While the initial aim is to post at least one video or photo per species, the long-term objective is to eventually include material showing a variety of biological aspects (e.g. feeding, breeding, etc.) for every species.
Jag letade efter en ljudinspelning på iberisk gransångare. Den fanns där och var inspelad av Theng den 18 maj 2007, Busör, Halland.
