| Summary: | This data file consists of state-space model-derived locations and individual data used to analyze transmitter effectsfor sea ducks in Eastern North America and is associated with the manuscript "Assessing year-round habitat use by migratory sea ducks in a multi-species context reveals seasonal variation in habitat selection and partitioning" published in Ecography. Columns are organized as follows: id - unique identifier species - species from which the centroid was obtained (BLSC = black scoter, COEI = common eider, LTDU = long-tailed duck, SUSC = surf scoter, WWSC = white-winged scoter) date- date of location (mm/dd/yy) jday - Julian date of location year - calendar year of location lon - longitude of location lat - latitude of location b - average assignment of location to either migrant (1) or resident (2) across all runs of the state-space model b.5 - most probable behavioral category based on average state assignment(1 = b ≤1.5 2 = b > 1.5) sex - sex of individual (M = male, F = female) age - age of individual (HY = hatch year, SY = second year, TY = third year, ASY = after second year, ATY = after third year, AHY = after hatch year capture_reg - general area where individual was captured capture_subreg - specific region within capture region where individual was captured stage - period of the annual cycle to which the centroid belongs (W = winter, B = breeding, S = spring staging, M = fall staging and molt, WM = winter migration, BM = breeding migration, MM = molt migration, SM = spring migration) site - position of centroid within season (i.e., W1 = first site occupied during winter, W2 = second site occupied, etc.) cycle - number of annual cycles following transmitter attachment (1 = first cycle after attachment, 2 = second cycle after attachment, etc.) season - season of annual cycle in which centroid occurred (W = winter, F = fall, B = breeding, S = spring)
