AB  - Accumulation of persistent organic pollutants (POPs) in wildlife may be 
      influenced by the physical and biotic environment, and concentrations vary 
      greatly among areas, seasons, and individuals. Different hypotheses about sources 
      of variation in perfluoroalkyl substance (PFAS) concentrations were examined in 
      eggs (n = 107) of tawny owls (Strix aluco) collected over a 24-yr period 
      (1986-2009) in Norway. Predictor variables included the North Atlantic 
      Oscillation (NAO), temperature, snow, food availability (vole abundance), and 
      individual traits such as age, body condition, and clutch size. Concentrations of 
      both perfluoro-octane sulfonate (PFOS) and perfluoroalkyl carboxylates (PFCAs) 
      varied several fold in the population, both inter- and intra-annually. Moreover, 
      individuals laid eggs with several times higher or lower PFAS concentrations 
      within few years (1 yr-5 yr). After controlling for temporal trends (i.e., 
      declining PFOS and increasing PFCA concentrations), both PFOS and PFCAs were 
      positively associated to the winter NAO in the previous year (NAOy - 1 ), 
      suggesting that atmospheric transport may be affecting the input of PFASs to the 
      local ecosystem. Perfluoro-octane sulfonate was negatively related to 
      temperature, but the pattern was complex as there was an interaction between 
      temperature and the feeding conditions. The PFOS accumulation was highest in 
      years with high vole abundance and low to medium temperatures. For PFCAs, there 
      was an interaction between NAOy - 1 and feeding conditions, suggesting that 
      strong air transport toward Norway and high consumption of voles led to a 
      moderate increase in PFCA accumulation. The individual traits, however, had very 
      little impact on the concentrations of PFASs in the eggs. The present study thus 
      suggests that annual variation in environmental conditions influences the 
      concentrations of PFASs in a terrestrial raptor such as the tawny owl.
