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.
