Metastatic Leiomyosarcoma Involving Bone and Kidney in an Adult Budgerigar (Melopsittacus undulatus)

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
A 2‐year‐old male budgerigar presents with swelling of the medial left leg. Soft tissue neoplasia is suspected after empirical treatment fails. Histopathology and immunohistochemistry (α‐SMA and desmin positivity, vimentin negativity) confirm leiomyosarcoma, with metastasis to bone and kidneys. This case documents uncommon metastatic spread in an avian

Demographic responses to population recovery illustrated by 30 years of monitoring a once critically endangered parrot

Journal of Applied Ecology, Volume 63, Issue 8, August 2026.
These findings highlight the dynamic nature of demographic processes throughout population recovery and emphasise the value of continued monitoring beyond apparent recovery to detect density‐dependent shifts in demographic rates of wildlife populations.

Using customs data to understand overlooked trade in non‐CITES birds between Africa and Asia

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract The international trade in live birds poses risks to animals, people, and biodiversity. To effectively mitigate these risks, decision‐makers require information on the volume, dynamics, and direction of trade. Despite Africa once being the largest exporter of birds by region, very little data exist on recent trade in live birds not listed on ...

Balancing conflict and coexistence: Interactions between invasive monk parakeets and native urban birds

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract Biological invasions often generate complex ecological paradoxes, particularly when invasive species act as ecosystem engineers that simultaneously compete with and benefit native communities. Understanding these dual dynamics is critical for managing urban biodiversity.
