Familiarity modulates preference for joint feeding with conspecifics in rats

This study shows that rats prefer joint feeding with unfamiliar non-cagemates over solitary feeding, indicating a high degree of social tolerance and prosocial behavior.

An exploratory study of behavioral traits and the establishment of social relationships in female laboratory rats

This study explores how individual behavioral traits affect social relationship formation in female rats, finding that exploration and boldness influence early stages while activity affects later stages.

Discrimination of conspecific head orientations and learning set formation in Bengalese finches

This study shows Bengalese finches can discriminate between conspecific frontal and lateral head orientations and form a learning set during training, but without a clear categorization boundary.

Measuring context dependency in birdsong using artificial neural networks

This study uses artificial neural networks to measure context dependency in birdsong, finding that context dependency decreases with finer syllable classifications.

Female Bengalese finches recognize their fathers song as sexually attractive

The study shows female Bengalese finches prefer their fathers' song over unfamiliar songs, suggesting early-life experience influences mate choice.

Effects of domestication on neophobia: A comparison between the domesticated Bengalese finch (Lonchura striata var. domestica) and its wild ancestor, the white-rumped munia (Lonchura striata)

This study compares neophobic responses between domesticated Bengalese finches and their wild ancestor, finding reduced neophobia in domesticated birds due to changes in selection pressure.

Domestication effects on aggressiveness: Comparison of biting motivation and bite force between wild and domesticated finches

This study compares aggressiveness and bite force between wild and domesticated finches to explore domestication's impact on behavioral traits.

Domestication effects on immune response: comparison of cell-mediated immune competence in wild and domesticated Bengalese finch

This study compares cell-mediated immune competence between domesticated Bengalese finches and their wild ancestor, finding higher immunocompetence in domesticated birds, suggesting no trade-off but a positive relationship with reproductive traits.
