Bird Species Database
(BSD) is being compiled in a framework of the Arctic Birds
Breeding Conditions Survey (ABBCS) of the International Wader
Study Group (IWSG). BSD aims at providing information on
distribution, numbers and breeding status of birds in the Arctic,
with the focus on last-breaking and, thus usually unpublished
information. The primary source of data is questionnaires filled
in by contributors to the ABBCS, while data from literature are
being added occasionally.
