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 (

PARENTAL ROLES AND THE MATING SYSTEM OF THE LONG-TOED STINT CALIDRIS SUBMINUTA
Long-toed Stint (Calidris subminuta) Science Article 2 abstract The mating system of the Long-toed Stint is poorly known. Observations of several broods in western Kamchatka in 1989 suggest a monogamous mating system in which incubation is shared, but with males caring for the brood after hatching Pavel S. Tomkovich, WSG Bull. 57: 42-43. Download article […]

First record of a long-toed stint (Calidris subminuta) in New Zealand
Long-toed Stint (Calidris subminuta) Science Article 1 abstract On 31 August 1997 Sheila Petch and Nick Allen were at Jarvis Road, Lake Ellesmere looking for shorebirds newly arrived from the Northern Hemisphere. While looking at a flock of recently arrived red-necked stints (Calidris ruflcollis) they noticed a bird of similar size, but with pale legs […]
Individual auditory recognition in the least tern (Sterna albifrons)
Little Tern (Sterna antillarum) Science Article 1 abstract Playback experiments performed in a colony of Least Terns near Fort Macon, North Carolina, demonstrated that adults can distinguish the call of their mate from that of a stranger. Sonagram analysis of the ‘Purrit-tit-tit’ call, the most common vocalization used when an adult approaches its mate, revealed […]
