Why don't birds lay more eggs?
Pat Monaghan,Ruedi G. Nager +1 more
TL;DR: Fifty years ago David Lack put forward a key hypothesis in life-history theory: that avian clutch is ultimately determined by the number of young that parents can provide with food, which needs to be extended to encompass the full demands of producing and rearing the brood.
Journal ArticleDOI
Experimental demonstration that offspring sex ratio varies with maternal condition
TL;DR: Experimental evidence is provided of an adaptive, facultative adjustment of sex ratio in response to changes in maternal condition in wild birds, which is commonly tested in wild populations.
Journal ArticleDOI
Carotenoids and egg quality in the lesser black-backed gull Larus fuscus: a supplemental feeding study of maternal effects
Jonathan D. Blount,Peter F. Surai,Ruedi G. Nager,David C. Houston,Anders Pape Møller,Michael L. Trewby,Malcolm W. Kennedy +6 more
TL;DR: The results suggest that carotenoids could be one resource responsible for egg quality maternal effects in birds, and the possible implications of carOTenoid–mediated effects on phenotype for fitness in mothers and their offspring are discussed.
Journal ArticleDOI
The price of eggs: increased investment in egg production reduces the offspring rearing capacity of parents
TL;DR: This work experimentally increased egg production in gulls and then examined their capacity to rear a control clutch, finding that the capacity of parents to rear the control brood was substantially reduced solely as a consequence of having themselves produced one extra egg.
Journal ArticleDOI
Prey selection and foraging performance of breeding Great Tits Parus major in relation to food availability
TL;DR: The results provide evidence why perfect timing of breeding is so important for the Great Tit, and contribute to the understanding of the causal link between food supply, growth and breeding success.
