Rethinking classic starling displacement experiments: evidence for innate or for learned migratory directions? Open
In an attempt to encourage the discourse on sources of individual variation in seasonal migration patterns and the microevolution of bird migration, we here critically examine the published interpretations of a now classic displacement stu…
Changes in the waterbird community of the Parc National du Banc d’Arguin, Mauritania, 1980–2017 Open
Summary The Parc National du Banc d’Arguin in Mauritania hosts the largest concentrations of coastal waterbirds along the East Atlantic Flyway. In spite of this importance, a review of the changes in the numbers of waterbirds in the area i…
Young Birds Switch but Old Birds Lead: How Barnacle Geese Adjust Migratory Habits to Environmental Change Open
Long-distance migratory animals must contend with global climate change, but they differ greatly in whether and how they adjust. Species that socially learn their migration routes may have an advantage in this process compared to other spe…
Northward range expansion in spring‐staging barnacle geese is a response to climate change and population growth, mediated by individual experience Open
All long‐distance migrants must cope with changing environments, but species differ greatly in how they do so. In some species, individuals might be able to adjust by learning from individual experiences and by copying others. This could g…

Food web consequences of an evolutionary arms race: Molluscs subject to crab predation on intertidal mudflats in Oman are unavailable to shorebirds Open
Aim Molluscivorous shorebirds supposedly developed their present wintering distribution after the last ice age. Currently, molluscivorous shorebirds are abundant on almost all shores of the world, except for those in the Indo‐West Pacific …
Marine biorhythms: bridging chronobiology and ecology Open
Marine organisms adapt to complex temporal environments that include daily, tidal, semi-lunar, lunar and seasonal cycles. However, our understanding of marine biological rhythms and their underlying molecular basis is mainly confined to a …
Colony-Breeding Eurasian Spoonbills in the Netherlands: Local Limits to Population Growth with Expansion into New Areas Open
It has been suggested that in most colony-breeding birds, food availability in thefeeding areas surrounding the colonies limits, and thereby regulates, populationsize. However, population size is also determined by adult survival, which wi…
The waterbirds of Parc National du Banc d’Arguin: Evaluation of all complete winter counts, workshop proceedings, and a future perspective Open
This is the report of an initiative to evaluate the results and methodology of all shorebird counts of the Banc d’Arguin in Mauritania. This was done by means of a workshop with all participants of the 2017 count expedition and a selection…
Red knot habits: An optimal foraging perspective on tidal life at Banc d’Arguin Open
Voedselvoorkeuren en sociaal gedrag verschillen tussen culturen wereldwijd, geldt niet alleen voor mensen. In dit proefschrift onderzoeken we het gedrag van kanoeten, wadvogels die overwinteren op de subtropische wadplaten van de Banc d’Ar…
Red knot habits : An optimal foraging perspective on intertidal life at Banc d’Arguin, Mauritania Open
Food preferences and social behaviour differ among cultures worldwide, not only in humans. This thesis describes studies of the behaviour of red knots, shorebirds that winter on the subtropical intertidal mudflats of Banc d’Arguin in Mauri…
Diet preferences as the cause of individual differences rather than the consequence Open
Summary Behavioural variation within a species is usually explained as the consequence of individual variation in physiology. However, new evidence suggests that the arrow of causality may well be in the reverse direction: behaviours such …
