TL;DR: In this paper, the authors conducted a survey of 77 saltmarsh sites around the coast of Britain in 1985 and 1996 and found that breeding densities were lowest on heavily grazed plots, and there was some evidence, from the larger number of survey sites for which data were available in 1985, that breeding density tended to be highest on lightly grazed and moderately/heavy grazing plots.

TL;DR: It is suggested that kleptoparasitism might be infrequent because birds could reduce its likelihood by adjusting their behaviour, with only a minimal cost in terms of a reduced intake rate.

TL;DR: Winter oystercatcher abundance in the Burry Inlet was correlated, however, with the number of birds wintering in the UK, and the abundance during spring was reduced, suggesting that overwinter cockle losses due to predation, fishing, and other sources of mortality cause increased prey depletion when the biomass of cockles at the start of the winter is small.

TL;DR: Data presented in this paper suggest that birds attempting to maximize their intake rate incur significant costs, in addition to those associated with searching for and handling prey, which are included in the Charnov model.

TL;DR: In this article, the authors report the results of two surveys of the same sample of 77 saltmarsh sites around the coast of Great Britain, conducted in 1985 and 1996 to estimate breeding abundance and the conservation status (i.e. stable, increasing or declining) of redshank Tringa totanus nesting on saltmarshes.
