Mogelijke oorzaken van slecht broedsucces in de visdiefkolonie bij terneuzen. Stand van zaken en aanbevelingen - 2003
Context of the study
Since 1997 the Dutch Coastal and Marine institute (RIKZ) monitors the coastal breading birdsin the Delta area. One of these breading birds is the common tern. In 1994 the colony in Terneuzen was struck by serious signs of illness, while the other colonies in the delta area remained healthy. The number of breading couples decreased strongly, and the broedsucces vertaling!!!! was bad. In 1999 and these signs of illness vanished the number of breading couples increased again. However, from 2000 on the eggs show anomalies (small cracks or bulges) which indicate that the population still hasn't recovered.
