Résumé :	The breeding numbers of Common Tern in the Netherlands during the course of the 20th century are reviewed. The current size of the Dutch population is about 12,000-13,000 pairs, down from around 45,000 in the 1930s. Most colonies are situated along the coast. The population has collapsed three times during the 20th century, in each case due to anthropogenic factors (egg collecting and shooting early in the century and during World War II, pollution in the 1960s). Today the population has not yet fully recovered from the last pesticide induced crash in the 1960s. It is argued that at least in the most important Dutch colony on Griend poor prey availability is probably the limiting factor, resulting in low breeding success and preventing further population growth.
