Oystercatcher (Haematopus ostralegus) Science Article 3 abstract Variation in rearing conditions, due either to parental or to environmental quality, can result in offspring of different quality (e.g. body condition, immune function). However, evidence is accumulating that egg size and composition can also affect offspring quality. In Oystercatchers Haematopus ostralegus , high-quality rearing conditions result in […]

Not all Oystercatchers Haematopus ostralegus select the most profitable common ockles Cerastoderma edule: a difference between feeding methods.
Oystercatcher (Haematopus ostralegus) Science Article 1 abstract We use an optimality model to describe prey choice by wintering Oystercatchers Haematopus ostralegus using different feeding methods . Birds fed on Common Cockles Cerastoderrrea edule, which they opened by either exclusively hammering or stabbing. The model includes probabilistic time costs associated with successful and unsuccessful prey handling, […]

Competitive abilities of oystercatchers (Haematopus ostralegus) occupying territories of different quality
Oystercatcher (Haematopus ostralegus) Science Article 2 abstract In territorial species, habitat heterogeneity results in some individuals occupying poor quality siteswhile others occupy high quality sites. Floaters (mature nonbreeders) may accept a low quality territory, because it is the best they can get and defend (
