The Ontogeny of Vocal Rhythms in a Non‐Human Primate

Developmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT Rhythm is a fundamental aspect of human behaviour, and musical rhythm provides one of its most elaborate instances. Unlike speech, this rhythmic behaviour is characterized by the production of temporal patterns structured around small‐integer ratios, which emerge early in life and change systematically across development.

Genome‐Wide Homozygosity Predicts Inbreeding Depression in the Hihi/Stitchbird (Notiomystis cincta) Better Than Realised Load

Evolutionary Applications, Volume 19, Issue 5, May 2026.
ABSTRACT Population declines result in increasingly small populations, which often experience an increase in inbreeding. Inbreeding may be negatively associated with fitness traits like survival and reproduction, that is, inbreeding depression, and is therefore detrimental to population persistence and adaptive potential.

Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

Journal of Anatomy, Volume 248, Issue 5, Page 830-842, May 2026.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, Volume 248, Issue 5, Page 873-887, May 2026.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.
