This study finds that blackcaps with Plasmodium coinfections have impaired oxidative status during autumn migration, affecting lipid damage and antioxidant capacity, with impacts on fitness and population dynamics.

The paper examines feather microstructure variation in great tits across urban-rural pairs, finding elevation and UV-B radiation, not urbanisation, drive geographic differences.

This study uses whole genome re-sequencing data from European robins to explore how migration behavior influences population structure, demography, and selection pressures across different geographic regions.

This study examines how environmental factors affect body condition in European robins, finding sex- and age-specific declines linked to temperature and soil moisture, with impacts on survival and population trends.

This study finds that malaria-like infections in juvenile birds delay their post-juvenile moult, potentially reducing their fitness by prolonging the period of incomplete plumage.
