Prey selection of a captive Oystercatcher Haematopus ostralegus hammering Mussels Mytilus edulis from the ventral side

The results replicate previous findings that ventral hammerers select Mussels of intermediate size, select against thick-shelled Mussels, abandon an increasing proportion of Mussels with increasing size and do nor pick up Mussels covered with barnacles.

Diet and foraging behaviour of oystercatchers ( Haematopus ostralegus ) and grey plovers ( Pluvialis squatarola ): The importance of intertidal flats

Results of a study on the feeding behaviour, diet and energetic needs of oystercatchers and grey plovers at the Bay of Heist, Belgium, using focal bird observations and macrobenthos sampling show the overall size of prey estimated was significantly correlated with the corresponding biomass.

Vigilance during food handling by Oystercatchers Haematopus ostralegus reduces the chances of losing prey to kleptoparasites

Evidence that scanning is associated with the high incidence of intra-specific food stealing among mussel-eating Oystercatchers is presented and the extra time which the less aggressive birds spent in vigilance seems best understood as a tactic for reducing food loss to kleptoparasites.

Morphology of the foolish mussel(Mytilus trossulus) : variation and defense

This thesis shows musical diversity in foolish mussels (M trossulus) in Howe Sound, British Columbia, is potentially important to interactions with mussel predators of the rocky intertidal community, and reviews the concepts of keystone species and trait-mediated indirect interactions, and makes the case that traitmediated interactions impact the structure and dynamics of the Howe Sound rocky interTidal community.

Foraging behaviour of oystercatchers Haematopus ostralegus specializing on different species of prey

Adult oystercatchers Haematopus ostralegus specializing on four prey species, the mussel Mytilus edulis, the winkle Littorina littorea, the ragworm Nereis diversicolor, and the clam Scrobicularia

The Impact of Bird Predation on Marine and Estuarine Bivalve Populations: A Selective Review of Patterns and Underlying Causes

Throughout the world, estuaries and coastal seas are important for many species of waders, ducks and geese either as a refueling site on migration or as wintering areas (see Davidson and Pienkowski

Prey Depletion and the Regulation of Predator Density: Oystercatchers ( Haematopus Ostralegus ) Feeding on Mussels ( Mytilus Edulis )

The outcome of these opposing tendencies expresses itself in a compromise, whereby the richest feeding areas are filled first, and as increasing numbers of birds utilize the area, marginal feeding areas come into use.

Optimal Foraging: A Selective Review of Theory and Tests

The general conclusion is that the simple models so far formulated are supported are supported reasonably well by available data and that the author is optimistic about the value both now and in the future of optimal foraging theory.

Optimal Foraging: Attack Strategy of a Mantid

A simple model of breadth of diet for a randomencounter situation is developed and compared to the behavior of a real predator, the mantid, Hierodula crassa, to show that this mantid supports the predicted behavior.
