This dataset represents a modeling effort intended to explore the impacts of oiling on migratory birds. The purpose of this model is to provide a first principles approach to predict potential biological impacts of altered energetics dynamics in north American migratory birds due to oiling of feathers. This data includes predicted theoretical impacts on migration timing, wintering latitude, starvation rates, and increased food uptake. This data was generated through model implementation in R (R Core Team 2020; Version 4.0.4).
During 2015, beachcast bird survey programs (Beach Watch and BeachCOMBERS) reported higher than average deposition of common murres (Uria aalge) on central and northern California beaches from August through December. Increased common murre mortality was not reported for southern California beaches. International Bird Rescue (IBR) located in Fairfield, CA and other coastal wildlife rehabilitation centers received more than 1,000 live, stranded and debilitated murres from Sonoma County to San Luis Obispo County during August – October. Approximately 2/3 of birds admitted to IBR were after-hatch-year birds in emaciated body condition and in various stages of molt, with extremely worn plumage. To determine the probable...
