Data: Implanted satellite transmitters affect sea duck movement patterns at short and long time scales

This data file consists of state-space model-derived locations and individual data used to analyze transmitter effects for sea ducks in Eastern North America and is associated with the manuscript "Implanted satellite transmitters affect sea duck movement patterns at short and long time scales" published in Condor. 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

tracking_day - number of days post-transmitter deployment

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)
