1 Exe Estuary SPA/Ramsar
Non-breeding populations; Avocet Black-tailed godwit Dark-bellied brent goose Dunlin Grey plover Oystercatcher Slavonian grebe restore Waterbird assemblage (>20,000 individuals)

2

3 Focusing on Oystercatcher
At designation the Exe supported 3980 individuals (5 year peak mean) At present 46% decline since classification. Possible reasons for decline Shell-fish resource (local factor) Human disturbance (local factor) Kleptoparasitism (local factor) Breeding productivity (off-site effect) Climate change (global effect)

4 Current & future work areas
Darvic ringing of oystercatcher over-winter and inter-annual survival fitness of individuals determining site turn-over and fidelity Functionally linked land GPS tagging?
