Avian Life History Evolution in Relation to Nest Sites, Nest Predation, and Food
Examination of variation and covariation of life history traits of 123 North American Passeriformes and Piciformes in relation to nest sites, nest predation, and foraging sites found that number of broods was much more strongly correlated with annual fecundity and adult survival among species than was clutch size, suggesting that clutch size may not be the primary fecundation trait on which selection is acting. Expand Food as a limit on breeding birds: a life-history perspective
Evidence for food limitation in the context of life history theory is reviewed because it provides a fundamental framework from which to interpret. Expand Nest Predation and Nest SitesNew perspectives on old patterns
Although the competition paradigm has been challenged, alternative explanations are rarely explored for birds, and new hypotheses need to be developed and examined. Expand Nest Predation Among Vegetation Layers and Habitat Types: Revising the Dogmas

Nesting mortality in general appears to be greater in shrub and grassland habitats, and species in these habitats are showing some of the most consistent long-term population declines, but evaluation of predation is complicated by habitat disturbance. Expand Parental care and clutch sizes in North and South American birds.
A detailed study of bird species in Arizona and Argentina shows that Skutch's hypothesis explains clutch size variation within North and South America, but neither Skutch’s hypothesis nor two major alternatives explain differences between latitudes.

The contrasting and interacting roles of food limitation versus mortality (nest predation) make birds an intriguing system for examining ecological and evolutionary causes of life history variation. Expand Nest predation increases with parental activity: separating nest site and parental activity effects
Both parental activity and nest sites exert antagonistic influences on current estimates of nest predation between nesting stages and both must be considered in order to understand current patterns of nestpredation, which is an important source of natural selection. Expand Parent birds assess nest predation risk and adjust their reproductive strategies.
It is shown that in safer environments parents increased investment in young through increased egg size, clutch mass, and the rate they fed nestlings, and that nest predation plays a key role in the expression of avian reproductive strategies. Expand Effects of ambient temperature on avian incubation behavior
It is demonstrated why linear correlation analyses across a wide range of temperatures can be inappropriate based on development of an incubation model for small birds that incorporates how ambient temperature influences both embryonic development and adult metabolism. Expand A new view of avian life-history evolution tested on an incubation paradox
It is shown that parents of species with lower adult mortality exhibit reduced nest attentiveness and that lower attentiveness is associated with longer incubation periods, however, the incubation period is also modified by juvenile mortality. Expand
