Avian vocal mimicry has been described in a variety of contexts, suggesting its function is multifaceted within and across species; however, basic empirical data describing mimetic signal prevalence and context are lacking for numerous species. We ex

Genetic analysis of avian mating systems has revealed that more than 70% of monogamous species show incidence of offspring parentage that does not match the social partner. Extra-pair parentage (EPP) has been linked to a variety of factors, including

Predation on eggs of marbled murrelets (Brachyramphus marmoratus) has been linked to poor recruitment of young, especially in California, Oregon, and Washington. Corvids have been implicated as the most influential egg predators on murrelets. Remnant

Effectiveness of rehabilitating wildlife following oil spills has been controversial. Impacts include mortality or changes in behavior affecting health or reproduction. Immediately following a bunker fuel oil spill on San Francisco Bay, California, U

Several species of birds and mammals cache food items, which in harsh conditions may translate into improved survival or reproductive success. Animals may benefit from evaluating the quality of cache items in terms of size, nutrition and storage viab

The handicap hypothesis broadly argues that ornamental traits and displays are costly to produce and are a function of individual quality and condition. Consequently, the extent of ornament expression can act as an honest indicator of quality, condit

Individuals that maintain pair bonds over multiple breeding attempts are often able to improve reproductive success compared to conspecifics that switch partners. However, the behavioral mechanisms driving this ‘mate familiarity effect’ are still

We explored the consequences of male and female explorative and risk-taking behaviors that are components of a behavioral syndrome, as well as basic demographic and physical characteristics of three measures of reproductive performance in Steller's J

Several species of animals, particularly corvids, will sample from a collection of items before making a decision. There is an expected trade-off between investing effort in making better choices and increased exposure to risk. Little is known about

The concept of partner compatibility in monogamous animals implies that individuals may reproduce better when paired to a partner with similar traits than to a higher quality, but dissimilar individual. We investigated whether partner similarities in
