Data from: Long-term and large-scale analyses of nest predation patterns in Australian songbirds and a global comparison of nest predation rates

Vladimír Remeš, Beata Matysioková & Andrew Cockburn
Juvenile mortality is one of crucial drivers of life-history evolution, and predation is the main cause of nest loss in birds. Thus, understanding how nest predation and failure vary in nature is important for understanding life history evolution and, moreover, for effective conservation. We used published data and unpublished records to study factors influencing nest predation and total failure in 138 populations of 90 species of Australian songbirds. Daily predation (average 2.0% d^−1) and failure...

Data from: Cross-fostering eggs reveals that female collared flycatchers adjust clutch sex ratios according to parental ability to invest in offspring

E. Keith Bowers, Pavel Munclinger, Stanislav Bureš, Petr Nádvorník, Lenka Kučerová & Miloš Krist
Across animal taxa, reproductive success is generally more variable and more strongly dependent upon body condition for males than for females; in such cases, parents able to produce offspring in above-average condition are predicted to produce sons, whereas parents unable to produce offspring in good condition should produce daughters. We tested this hypothesis in the collared flycatcher (Ficedula albicollis) by cross-fostering eggs among nests and using the condition of foster young that parents raised to...

Data from: Faithful females receive more help: the extent of male parental care during incubation in relation to extra-pair paternity in songbirds

Beata Matysioková & Vladimír Remeš
Parental care provided by males occurs in a diverse array of animals and there are large differences among species in its extent compared to female care. However, social and ecological factors responsible for interspecific differences in male’s share of parental duties remain unclear. Genetic fidelity of females has been long considered important. Theory predicts that females should receive more help from their mates in raising the offspring in species with high genetic fidelity. Using avian...

Data from: Nest predation in New Zealand songbirds: exotic predators, introduced prey and long-term changes in predation risk

Vladimír Remeš, Beata Matysioková & Andrew Cockburn
Predation is a major factor in ecology, evolution and conservation and thus its understanding is essential for insights into ecological processes and management of endangered populations of prey. Here we conducted a spatially (main island through to offshore islets) and temporally (1938-2005) extensive meta-analysis of published nest predation rates in New Zealand songbirds. We obtained information on nest predation rates from 79 populations (n = 4838 nests) of 26 species of songbirds belonging to 17...
