The link between colorfulness and extinction risk across the world's passerine birds

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as coloration directly affect human interactions with wildlife.

Exploring the exploration: implications of leaving or remaining at the natal site during the early stages of independence in a partially migratory bird

Ibis, Volume 168, Issue 4, Page 1210-1229, October 2026.
Despite being an important fraction of any animal population, juveniles are a severely understudied group. Juveniles often need to learn an array of skills that allow them to survive independently and do so while undertaking decisions that may impact their fitness, recruitment and survival, having therefore relevant demographic implications.

Life‐stage variation in Sable Shearwater (Ardenna carneipes) physiology assessed using proteomics

Ibis, Volume 168, Issue 4, Page 1500-1515, October 2026.
Life‐stage transitions in seabirds involve substantial shifts in physiological demands, yet the molecular mechanisms underpinning these changes remain poorly resolved. Here we applied untargeted data‐independent acquisition mass spectrometry (DIA‐MS) to characterize and compare the plasma proteomes of fledgling and adult Sable Shearwaters Ardenna ...

Food supplementation reduces early‐stage nest attendance under adverse weather conditions in Red Kites

Ibis, Volume 168, Issue 4, Page 1410-1421, October 2026.
Parental care strategies have evolved to ensure optimal offspring rearing under varying environmental conditions. Nest attendance is a fundamental behaviour providing protection against predators and adverse weather, but it is traded against time spent foraging.

Counter‐factual simulation highlights requirements for additional management to avert extinction of a relict Tītī/Sooty Shearwater population

Ibis, Volume 168, Issue 4, Page 1348-1363, October 2026.
Seabirds play key ecological roles but face increasing threats worldwide. Among them, Tītī (Sooty Shearwater) Ardenna grisea are among the most abundant and culturally significant species in the Southern Hemisphere but are also threatened. Kapiti Island, Aotearoa (New Zealand), holds a Tītī colony which, despite eradication of non‐native mammalian ...

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

Journal of Anatomy, Volume 249, Issue 4, Page 705-713, October 2026.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...

Metastasis of Invasive Ductal Carcinoma of the Breast to the Uterine Cervix 30 Years Post‐Mastectomy: A Case Report

Journal of Obstetrics and Gynaecology Research, Volume 52, Issue 10, October 2026.
ABSTRACT Metastasis of invasive ductal carcinoma of the breast to the uterine cervix is rare, with only one report of a case occurring more than 20 years after the primary surgery. A 69‐year‐old woman presented with abnormal uterine cervical cytology (atypical glandular cells without tumor diathesis) 30 years after undergoing breast cancer surgery ...
