This paper tests the possibility that, primarily through their effect on invertebrate prey densities, sediment characteristics can be used to predict the densities of shorebirds (Charadrii), on the inner banks of the Wash, east England. 192 quadrats were established with, on most shores, a transect of nine quadrats from the marsh edge to the Low Water Mark (LWM). Shorebirds were counted in winter in each quadrat. The densities of the main invertebrate prey species were sampled in early winter/late autumn at the mid-point of each quadrat, together with the sediment particle size and organic content. The time for which each quadrat was inundated over high water spring tides was also measured |
