Shifting Seasons: Long‐Term Insights Into Climate Change Effects on Bird Phenology From Ringing Data

Ecology and Evolution, Volume 15, Issue 10, October 2025.
This study analyses a 25‐year bird ringing dataset from Spurn Bird Observatory to assess how climate change affects migratory bird arrival times and species abundance. While there was a weak association between climate and abundance trends, phenological timings are significantly affected.

Ectoparasite and trichomonosis management improve nestling golden eagle (Aquila chrysaetos) health and survival: An effective mitigation strategy

Journal of Applied Ecology, Volume 62, Issue 10, Page 2764-2773, October 2025.
For sensitive or at‐risk bird species, treating parasites and disease can improve nest productivity and support population growth, making it a valuable conservation tool. In areas with high concentrations of poultry bugs or where eagles consume avian vectors of Trichomonas spp., pathogen and parasite treatments may serve as an effective mitigation ...

Wildlife health risk analysis for conservation translocation: A scalable approach illustrated for wader population restoration

Conservation Science and Practice, Volume 7, Issue 9, September 2025.
We present a methodological framework for health risk analysis (disease risk analysis) for conservation translocation that enables the process to be scaled and adapted to the project context. We illustrate its application to two wader (shorebird) population restoration projects with differing translocation plans.

Surviving in a changing world: weather and juvenile condition matter for a long‐lived avian predator, but blood parasites do not appear to

Oikos, Volume 2025, Issue 7, July 2025.
Survival is commonly the most critical factor influencing population growth in long‐lived species. Hence, identifying factors shaping variation of survival rates is crucial to understand and predict population trajectories in a changing world. We investigated the factors influencing survival in a long‐lived diurnal bird of prey, analysing the effectsof
