Shifting Syllable Production in an Ex Situ Population of a Critically Endangered Songbird
Zoo Biology, EarlyView.Bali mynas produced songs containing more syllables under increased anthropogenic disturbance. ABSTRACT Singing is an ecologically important behaviour for songbirds. Syllables function as the building blocks of birdsong, so changes to their production will have implications for overall song structure.

Habitat imprinting in breeding territory selection of a long‐lived bird of prey
Journal of Animal Ecology, EarlyView.A unique long‐term dataset has allowed this study of an important habitat selection mechanism, habitat imprinting, in a species which is typically extremely challenging to study. It gives us better understanding of the role of early experience in selection of breeding sites in long‐lived species with high breeding site fidelity.

Nighttime roosting substrate type and height among 4 strains of laying hens in an aviary system1
Poultry Science, 2019 Multi‐tiered aviaries for laying hens are designed to provide resources, such as perches, that allow birds to perform natural behaviors, thus improving their welfare. This research examined nighttime roosting heights and substrates used by laying hens of

Integrative Zoology, EarlyView.This study examines the ecophysiological responses of common waxbills to temperature variation in Portugal. We measured body condition and basal metabolic rate (BMR) during summer and winter across two regions in Portugal. Body condition was negatively correlated with temperature, while the relationship between BMR and temperature varied seasonally. In

Methods in Ecology and Evolution, EarlyView.Abstract Collection of large behavioural data‐sets on wild animals in natural habitats is vital in ecology and evolution studies. Recent progress in machine learning and computer vision, combined with inexpensive microcomputers, has unlocked a new frontier of fine‐scale markerless measurements.
