Start of 40th annual worldwide waterbird count


Most observers are members of enthusiastic voluntary networks, with professional coordination at the national level. Altogether they spend about 50,000 hours on this fieldwork. Wetlands international organizes a standard method for the count, which makes it easy to compare yearly census data. Each year, between 30 million and 40 million waterbirds are counted in every continent except Antartica.

Every three years Wetlands International summarises all the count data in the publication Waterbird Population Estimates; the fourth edition will be released shortly. This publication is a unique source of information on the trends in the world’s waterbird populations, offering crucial information on 878 waterbird species.

The IWC is more than a program to estimate the size of waterbird populations; from the outset it has been a global tool for waterbird conservation. The IWC makes it possible to monitor changes in waterbird numbers and distribution, to improve knowledge of little-known waterbird species and to raise awareness of the importance of waterbirds.

With waterbirds being very good indicators for assessing the status of wetlands globally, regular tracking of waterbird populations also helps to identify priorities for the conservation of wetland sites at the local, national and international level. It is a guideline for Intergovernmental Agreements on the Environment such as the Ramsar convention on wetlands, the Convention on Migratory Species (CMS, Bonn Convention) and the specific agreements about flyways.
