TLDR
The nutritional requirements of egg formation in lesser blackbacked gulls Larus fuscus L., are investigated through a series of feeding experiments providing additional food of different quality.Abstract:
The use of supplementary feeding experiments to investigate the relationship between food supply and clutch and egg size in birds has yielded disparate results, some authors showing an advancement in laying date and/or increased clutch size in response to additional food whereas other studies have found no effect. Here we investigate the nutritional requirements of egg formation in lesser blackbacked gulls Larus fuscus L., through a series of feeding experiments providing additional food of different qualityread more

Carry‐over effects as drivers of fitness differences in animals
TL;DR: Carry-over effects are likely to be far more widespread than currently indicated, and they could feasibly be responsible for a large amount of the observed variation in performance among individuals, and warrant a wealth of new research designed specifically to decompose components of variation in fitness attributes related to processes across and within seasons.

Intraspecific variation in egg size and egg composition in birds: effects on offspring fitness
TL;DR: It is suggested that the most important effect of variation in egg size might be in determining the probability of offspring survival in the first few days after hatching, and the hypothesis that large eggs give rise to heavier chicks at hatching is supported.

Seabirds as monitors of the marine environment
TL;DR: In this paper, the authors used stable isotopes of N and C from the same feathers used for mercury measurement, a technique that also permits the monitoring of trophic status over time or between regions.

Avian egg size: variation within species and inflexibility within individuals
TL;DR: Egg size appears to be a characteristic of individual females, and yet the traits of a female that determine egg size are not clear, and the available evidence suggests that egg size may be more flexible within individuals.

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.

TL;DR: Evidence for food limitation in the context of life history theory is reviewed because it provides a fundamental framework from which to interpret.

Food supplementation experiments with terrestrial vertebrates: patterns, problems, and the future
TL;DR: The typical population response to food supplementation was two- to three-fold increase in density, but no change in the pattern of population dynamics, which points to the need for researchers to conduct food supplementation experiments in tropical environments.

TL;DR: The first book to approach the morphological, physiological and behavioral development of birds from an ecological and evolutionary perspective, this approach allows new insights into previously unrelated phenomena such as mate recognition, navigational ability, song, sibling aggression and fratricide.

Relationship between egg size and post-hatching chick mortality in the herring gull (Larus argentatus).
TL;DR: In a series of egg transfer experiments carried out on the Isle of May, Scotland, it has been possible to demonstrate at least two factors contributing to this differential mortality of herring gull chicks, namely the size disadvantage and the sequence of hatching.
