Monitoring van kustbroedvogels in de SBZ-V ‘Kustbroedvogels te Zeebrugge-Heist’ en de westelijke voorhaven van Zeebrugge tijdens het broedseizoen 2014

In Zeebrugge all 3 tern species used to exceed the threshold of 1% of their respective biogeographic population considerably. In 2014 none of the tern species reached this threshold.

Crested Lark, Northern Wheatear, Mediterranean Gull and Yellow-legged Gull used to breed in the Zeebrugge port but in 2014 these species were no longer recorded. The numbers of Oystercatchers and Common Gull seem to have stabilised at a level much lower than before. Only the population of Common Ringed Plover is rather stable at about 8 pairs.Following a slight reduction in 2013, the populations of Herring and Lesser Black-backed Gulls further and strongly declined in 2014. Both species used to exceed the 1% level (maxima of 1.2 and 2.8%, respectively for Herring and Lesser Black-backed Gull), the number of Herring Gulls dropped to 0.2% of the total biogeographic population while that of Lesser Black-backed Gull dropped to 0.6%. This decline is due to disturbance by foxes and a decreased availability of suitable nesting areas.
