Great variability in nest lining size: support for thermoregulation but not for anti-predatory adaptation hypothesis

Popis výsledku v původním jazyce

Nest lining is a key component in nests of many bird species. Among ground nesting birds with open nests, it usually consists of dry sticks and stalks creating a thermoregulatory insulating layer for the eggs. However, a bigger nest lining can attract predators and increase nest mortality. The factors influencing behavioural plasticity in birds facing the tradeoff between nest lining thermoregulation and conspicuousness for predators have remained poorly understood. The Northern Lapwing Vanellus vanellus, a visibly incubating shorebird with an active nest defence against potential predators, demonstrates great variability in the size of nest lining and, at the same time, is subject to a high frequency of nest predation. We analysed the variability of nest lining size across time and space in 915 measurements of 601 lapwing nests in South Bohemia, Czech Republic, 2010 to 2015. We show that lapwing nests placed closer to small water pools with generally cooler microclimates had bigger nest lining. The
