Résumé :	Based on experience gathered during a longterm research project at Wilhelmshaven (Lower Saxony, Germany), methodological recommendations are given for studies of reproductive biology and breeding success of Common Terns. Aspects considered here are intervals and practice of control checks in the colony, field equipment, marking of nests and eggs, fencing of nests (as a prerequisite to determine fledging success), age characteristics of Common Tern chicks and data recording. A field box for efficient storage and transport of equipment is described. Chicks can be weighed reliably on an electronic balance within such a box. Common causes of egg and chick losses are explained. Sampling of pellets and food remains is recommended.
