Nocturnal flight activity (NFA) and diurnal flight activity (DFA)\u2014Nocturnal and diurnal flight activity can influence the risk of collision; therefore, we used available information to estimate the amount of time each species spent flying during night and during day. Time spent in the rotor sweep zone (RSZt)\u2014 the percentage of time each species spends flying at the same height as wind turbine blades (as opposed to above or below the sweeping zone of the blades) will influence collision vulnerability. Based on flight-height analyses and published accounts, we estimated each species\u2019 percentage of time flying within the rotor sweep zone (RSZ; 10-200 m above the water). Macro-avoidance (MA)\u2014The macro-avoidance values for species indicate the species-specific probability of avoidance with wind power infrastructure. For each species, we derived this value from observed macro-avoidance (via human observation and radar) at existing offshore wind power sites. In cases where species-specific data were not available, we used information from similar taxa. \nThese data support the following publication: Adams, J., Kelsey, E.C., Felis J.J., and Pereksta, D.M., 2016, Collision and displacement vulnerability among marine birds of the California Current System associated with offshore wind energy infrastructure: U.S. Geological Survey Open-File Report 2016-1154, 116 p., https://doi.org/10.3133/ofr20161154.\nThese data were updated in August 2017: 5 values in the relative displacement vulnerability column have been updated.
