BIRD SPECIES DATABASE: INTRODUCTION

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on distribution, numbers and breeding status of birds in the Arctic, with the focus on last-breaking and, thus usually unpublished information.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.
