Brief_description
Tidal lagoon and open estuary of the Knysna River. Globally significant numbers of the near-threatened African Black Oystercatcher in winter, and nationally significant numbers of this and Cape Shoveller in summer, when good numbers of Yellowbilled Duck also occur in some years. Noteworthy counts of Grey Plover, Greenshank, Curlew Sandpiper and Whimbrel in summer, and of Blackwinged Stilt in winter. Seasonal variation in types of birds using site well shown by biomass and total count graphs: large numbers of small birds (mostly shorebirds) in summer and smaller numbers of large birds (cormorants, egrets, ibises, gulls) in winter. Critically threatened by siltation from local urban development; important threats are bait collection, recreational activities and harassment by dogs.
