Shorebird feeding specialists differ in how environmental conditions alter their foraging time

Feeding specialisation is a common cause of individual variation. Fitness payoffs of specialisation vary with environmental conditions, but the underlying behavioural mechanisms are poorly understood. Such mechanistic knowledge, however, is crucial to reliably predict responses of heterogeneous populations to environmental change. We quantified spatiotemporal allocation of foraging behaviour in wintering Eurasian oystercatchers (Haematopus ostralegus), a species in which feeding specialisation can be inferred from bill shape. We combined GPS and accelerometer data to quantify foraging...

Data from: Cumulative energetic costs of military aircraft, recreational and natural disturbance in roosting shorebirds

Knowing the consequences of disturbance for multiple species and all disturbance sources is crucial to mitigate disturbance impacts in densely populated areas. However, studies that observe the complete disturbance landscape to estimate cumulative costs of disturbance are scarce. Therefore, we quantified responses, frequencies and energetic costs of disturbance of four shorebird species on five high tide roosts in the Wadden Sea. Roosts were located either in a military air force training area or were predominantly...

Seed mass, hardness and phylogeny determine the potential for endozoochory by granivorous waterbirds

Ádám Lovas-Kiss, Orsolya Vincze, Erik Kleyheeg, Gábor Sramkó, Levente Laczkó, Réka Fekete, Attila Molnár V. & Andy Green
Field studies have shown that waterbirds, especially members of the Anatidae family, are major vectors of dispersal for a broad range of plants whose propagules can survive gut passage. Widely adopted dispersal syndromes ignore this dispersal mechanism, and we currently have little understanding of what traits determine the potential of angiosperms for endozoochory by waterbirds. Results from previous experimental studies have been inconsistent as to how seed traits affect seed survival and retention time in...
