AB  - It is widely accepted that body concentrations of persistent organic pollutants 
      (POPs) tend to increase with trophic level (TL). Yet, little attention has been 
      paid to the causes in the underlying differences in POP body concentrations 
      between species occupying similar TLs. In this paper we use two modeling 
      approaches to quantify the importance of migration and opportunistic feeding, 
      relative to that of trophic level, in explaining interspecific differences in 
      polychlorinated biphenyl (PCB) body concentrations between 6 Arctic seabird 
      species breeding in the Barents Sea: Little Auk (Alle alle), Black Guillemot 
      (Cepphus grylle), Brunnich's Guillemot (Uria lomvia), Common Eider (Somateria 
      mollissima), Black-legged Kittiwake (Rissa tridactyla), and Glaucous Gull (Larus 
      hyperboreus). As a first approach, we use additive models to analyze two 
      independent data sets (n = 470 and n = 726). We demonstrate that migration, 
      opportunistic feeding, and TL significantly (p < 0.001) increase PCB body 
      concentrations by a factor 3.61-4.10, 2.66-20.95, and 2.38-2.41, respectively. 
      Our second approach, using a mechanistic bioaccumulation model, confirmed these 
      positive effects on the body burdens but suggested lower effects of migration, 
      opportunistic feeding, and TL (1.55, 2.39, and 2.38) than did our statistical 
      analysis. These two independent approaches demonstrate that the effects of 
      migration and opportunistic feeding on seabird body burdens can be similar to 
      that of an increase of one TL and should therefore be accounted for in future 
      analyses.
