Novel Approach to Inter‐Onset‐Interval Ratio Uncovers Music‐Like Rhythmic Patterns in Budgerigar (Melopsittacus undulatus) Warble Song

Annals of the New York Academy of Sciences, Volume 1557, Issue 1, March 2026.
Recent work on non‐human animal vocalizations has offered new insights into rhythmicity. In an attempt to improve upon methods commonly used in animal rhythm research, we investigated the rhythmic structure of budgerigar song. Our proposed statistical approach showed rhythmicity in human music but not language, and uncovered non‐random structured ...

Grassland bird diversity and abundance in the presence of native and non-native grazers

Avian Conservation and Ecology, 2021
Temperate grassland biomes are globally imperiled, and grassland birds are in precipitous decline as a result. The majority of North America's grassland birds breed on rangelands occupied by domestic cattle, but reintroductions of bison to restore ...

Semiparametric regression for circular response with application in ecology

Scandinavian Journal of Statistics, Volume 53, Issue 1, Page 54-101, March 2026.
ABSTRACT A regression model for a circular response variable depending on a linear or a circular predictor is presented in this paper. The conditional density belongs to a parametric flexible family that allows for asymmetry and varying peakedness around the modal direction.

Novelty Induces Behavioural And Glucocorticoid Responses In A Songbird Artificially Selected For Divergent Personalities [PDF]

, 2017
Stress physiology is thought to contribute to individual differences in behaviour. In part this reflects the fact that canonical personality measures consist of responses to challenges, including novel objects and environments.

Stable immune function during moult regardless of age‐specific moulting strategy in a European passerine

Journal of Avian Biology
Moult, the regular replacement of feathers, is a resource‐intense avian annual‐cycle stage. Resource allocation to support feather regrowth may require downregulation of other physiological processes, such as immune function, which is critical for ...

Chance, long tails, and inference: a non-Gaussian, Bayesian theory of vocal learning in songbirds

, 2017
Traditional theories of sensorimotor learning posit that animals use sensory error signals to find the optimal motor command in the face of Gaussian sensory and motor noise.
