Analysis of CR1 Repeats in the Zebra Finch Genome [PDF]
Journal of Systemics, Cybernetics and Informatics, 2013 Most bird species have smaller genomes and fewer repeats than mammals. Chicken Repeat 1 (CR1) repeat is one of the most abundant families of repeats, ranging from ~133,000 to ~187,000 copies accounting for ~50 to ~80% of the interspersed repeats in the ...

Discrimination of natural acoustic variation in vocal signals
Scientific Reports, 2021 Studies of acoustic communication often focus on the categories and units of vocalizations, but subtle variation also occurs in how these signals are uttered.

Stable Propagation of a Burst Through a One-Dimensional Homogeneous Excitatory Chain Model of Songbird Nucleus HVC [PDF]
, 2006 We demonstrate numerically that a brief burst consisting of two to six spikes can propagate in a stable manner through a one-dimensional homogeneous feedforward chain of non-bursting neurons with excitatory synaptic connections.

Journal of Animal Ecology, EarlyView.This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

The American Biology Teacher, 1979 IANIMALS IN GENERAL and vertebrates in particular display little of their repertoire of behaviors in confined situations. Classroom observations of the behavior of Planaria, Daphnia, and Anolis often are less than rewarding for students. However, the problems encountered in observing organisms in their natural environments need not restrict the ...

To transduce a zebra finch: interrogating behavioral mechanisms in a model system for speech. [PDF]
, 2017 The ability to alter neuronal gene expression, either to affect levels of endogenous molecules or to express exogenous ones, is a powerful tool for linking brain and behavior. Scientists continue to finesse genetic manipulation in mice.

Social information about others' affective states in a human‐altered world
Journal of Animal Ecology, EarlyView.Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Molecular architecture of the zebra finch arcopallium
Journal of Comparative Neurology, 2019 AbstractThe arcopallium, a key avian forebrain region, receives inputs from numerous brain areas and is a major source of descending sensory and motor projections. While there is evidence of arcopallial subdivisions, the internal organization or the arcopallium is not well understood.

The birds of the Bush Heritage, Cravens Peak Reserve [PDF]
, 2009 Bird communities were studied in two subregional areas of Cravens Peak, the Toko Plains and the Simpson-Strzelecki Dunefields, using the point counts method. A total of 42 2ha 20 minute surveys, 46 five-hundred metre radius area surveys and 170 5km drive

Ethology, EarlyView.We raised fall field crickets in acoustic environments of silence, their own song, traffic noise, or the song of the recently introduced Japanese burrowing cricket and measured development, size, and adult survival. We found that crickets reared with burrowing cricket song developed more quickly than crickets reared in silence.
