Condition- and parasite-dependent expression of a male-like trait in a female bird.Timing of initial arrival at the breeding site predicts age at first reproduction in a long-lived migratory bird.Excretion patterns of coccidian oocysts and nematode eggs during the reproductive season in Northern Bald Ibis (Geronticus eremita)Social and environmental factors modulate leucocyte profiles in free-living Greylag geese (Anser anser).Experimentally elevated levels of testosterone at independence reduce fitness in a territorial bird.Effects of mate separation in female and social isolation in male free-living Greylag geese on behavioural and physiological measures.Intra-sexual competition alters the relationship between testosterone and ornament expression in a wild territorial bird.Characterizing demographic variation and contributions to population growth rate in a declining populationMeasures of predator diet alone may underestimate the collective impact on prey: Common buzzard Buteo buteo consumption of economically important red grouse Lagopus lagopus scotica
