Stopover behaviour and departure decision of northern wheatears, Oenanthe oenanthe, facing different onward non-stop flight distances
Abstract. On the small North Sea island Helgoland (54°11′ N, 07°55′ E) we studied the stopover ecology of two subspecies of northern wheatear, Oenanthe oenanthe, during spring migration. BirdsExpand

Differential timing of spring migration in northern wheatears Oenanthe oenanthe: hurried males or weak females?
In a field experiment on the island of Helgoland (southeast North Sea), we investigated whether migration strategy or competition between the sexes cause the differential timing of spring migrationExpand

Seabirds and offshore wind farms in European waters: Avoidance and attraction
The extent to which seabirds are displaced from, or attracted to, offshore wind farms (OWFs) is uncertain, but rapid development of OWFs in European waters could conflict with seabird conservation.Expand

Daily stopovers as optimal migration strategy in a long-distance migrating passerine : the Northern Wheatear Oenanthe oenanthe
Selection for early arrival is expected to shape optimal stopover decisions in migrating birds to minimise time spent on migration. Optimality models predict that fuel loads at departure fromExpand

Effects of ship traffic on seabirds in offshore waters: implications for marine conservation and spatial planning.
Most anthropogenic influences on marine ecosystems, except for river- or terrestrial-borne pollution, involve some sort of vessel activity. Increasing anthropogenic activities mean that manyExpand

Intake rates and the functional response in shorebirds (Charadriiformes) eating macro‐invertebrates
As field determinations take much effort, it would be useful to be able to predict easily the coefficients describing the functional response of free‐living predators, the function relating foodExpand

Prevalence and intensity of excretion of coccidial oocysts in migrating passerines on Helgoland
Prevalence and intensity of excretion of coccidial oocysts in actively migrating passerines (Turdus philomelos, Fringilla coelebs, Sylvia borin, Phoenicurus phoenicurus) were assessed in spring andExpand

Feeding ecology of dunlins Calidris alpina staging in the southern Baltic Sea, 1. Habitat use and food selection
The feeding habits of migrating dunlins Calidris alpina staging in different non-tidal coastal habitats in the southern Baltic Sea are described. The study also focuses on the structure of theExpand

Optimal bird migration and predation risk: a field experiment with northern wheatears Oenanthe oenanthe
Summary 1 Experiments testing predictions of optimal migration theory so far have concentrated on time and energy as the expenses that birds strive to minimize during migration. Taking advantageExpand
