Biparental care is a critical and, occasionally, unequally shared obligation that ensures that young survive to maturity. Such care may be complicated in systems in which one parent, typically the male, is unsure of his genetic relatedness ...
Generalization of learned preferences covaries with behavioral flexibility in red junglefowl chicks [0.03%]

The relationship between animal cognition and consistent among-individual behavioral differences (i.e., behavioral types, animal personality, or coping styles), has recently received increased research attention. Focus has mainly been on li...
Socio-ecological conditions and female infidelity in the Seychelles warbler [0.03%]

Within socially monogamous breeding systems, levels of extra-pair paternity can vary not only between species, populations, and individuals, but also across time. Uncovering how different extrinsic conditions (ecological, demographic, and s...
Experimental field evidence that out-group threats influence within-group behavior [0.03%]
实验田间证据表明外群威胁影响内群行为

In social species, conspecific outsiders present various threats to groups and their members. These out-group threats are predicted to affect subsequent within-group interactions (e.g., affiliation and aggression) and individual behavior (e...
Effects of manipulated levels of predation threat on parental provisioning and nestling begging [0.03%]
操控捕食者威胁水平对亲鸟育雏及雏鸟乞食行为的影响

Parental provisioning behavior is a major determinant of offspring growth and survival, but high provisioning rates might come at the cost of increased predation threat. Parents should thus adjust provisioning activity according to current ...
Experimentally induced antipredator responses are mediated by social and environmental factors [0.03%]
实验证明抗捕食者反应由社会和环境因素介导

Frank Groenewoud et al.
Nest predation is a common cause of reproductive failure for many bird species, and various antipredator defense behaviors have evolved to reduce the risk of nest predation. However, trade-offs between current reproductive duties and future...
Natal habitat and sex-specific survival rates result in a male-biased adult sex ratio [0.03%]

The adult sex ratio (ASR) is a crucial component of the ecological and evolutionary forces shaping the dynamics of a population. Although in many declining populations ASRs have been reported to be skewed, empirical studies exploring the de...

Wildlife can respond to urbanization positively (synanthropic) or negatively (misanthropic), and for some species, this is a nonlinear process, whereby low levels of urbanization elicit a positive response, but this response becomes negativ...
Collective responses to heterospecifics emerge from individual differences in aggression [0.03%]

Variation in individual behavior among group members impacts collective outcomes. The ability of both individuals and groups to outcompete others can determine access to resources. The invasive Argentine ant, Linepithema humile, dominates r...
Breeding success but not mate choice is phenotype- and context-dependent in a color polymorphic raptor [0.03%]
在一种色彩多型的猛禽中，育雏成功而非配偶选择具有表型和情境依赖性

Morph-specific mate choice has been proposed as one of the evolutionary mechanisms that contribute to the maintenance of variation in color polymorphic systems. Coloration usually covaries with other phenotypic traits affecting life history...
