Data for Songbirds initiate migratory flights synchronously relative to civil dusk

Data for published paper in Movement Ecology "Songbirds initiate migratory flights synchronously relative to civil dusk". <br> These three datasets include all data necessary to recreate results and figures in the paper. Variable explanations for each are below. <br> <strong>Net_Displacement.Rdata</strong> Motus_First_Tag_ID = unique identifier for each individual Species_Season = identifier for species and season observed Mig_Time = time elapsed in hours between detection and departure Net_Displacement_Dist_Neg = distance in kilometers between detection site and departure site Shape = variable needed for ggplot plotting <br> <strong>Departure_Time.Rdata</strong> Species_Season = identifier for species and season observed Spring_or_Fall_Departure = Season of departure Year = year of departure Age = Age at departure (HY = hatch year, AHY = after hatch year, SY = second year, ASY = after second year) Sex = sex of individual Departure_DateTime_UTC = departure date and time in UTC time zone Sunset = time of local sunset in UTC Dusk = time of local civil dusk in UTC Min_After_Sunset = time of departure in minutes elapsed since sunset Min_After_Dusk = time of departure in minutes elapsed since dusk SunAngle_Degrees = sun elevation angle at departure Motus_First_Tag_ID = Motus Tag ID for each individual ID = unique ID of each individual <br> <strong>Clouds_and_Departure_Time.Rdata</strong> Year = year of departure Species_Season = identifier for species and season observed Min_After_Dusk = time of departure in minutes elapsed since dusk Tot_Cloud_Cover.HrOf.31km = estimated total cloud cover for the hour of civil dusk Overcast = binary overcast (&gt;= 95%) vs. mostly clear (&lt;= 25%) variable
