TL;DR: Dual constraints (one biotic, one abiotic) on the song frequency range of urban animals are revealed for the first time, consistent with the hypothesis that birds with longer beaks and therefore longer vocal tracts sing songs with lower maximum frequencies because longer tubes have lower-frequency resonances.

TL;DR: The annual cycles of Pygoscelis penguins are reviewed to better understand what is known about their phenology, what causes known changes, and how their Phenology influences fitness.

TL;DR: This report describes the methodology associated with the Zooniverse project Penguin Watch, and presents anonymised volunteer classifications for the 73,802 images, alongside the associated metadata (including date/time and temperature information).

TL;DR: This is the first report of PenCV in Chinstrap Penguins and the first detection outside of Ross Island, East Antarctica, and future samples from Antarctic wildlife should be screened for these and other viruses to determine the prevalence and potential impact of viral infections.

TL;DR: The results support the idea that aggregations of gentoo chicks decrease an individual’s energetic expenditure when wet, cold conditions are present, and find significant differences in aggregation behavior between the lowest latitude site, Maiviken, South Georgia, and two of the higher latitude sites on the Antarctic Peninsula, suggesting this behavior may be colony specific.
