Summary
In this data set, records (rows) represent the distance between primary daytime roosts and night (feeding) locations of ducks marked with telemetry in California in years 2015-16, 2016-17, and 2017-18, during October - March. Years 2015-16, 2016-17, and 2017-18 represented drought, non-drought, and non-drought, respectively. Matchett and company (2020; see Larger Work section for citation) summarized this data set in figures E3 and E4 to compare distances moved among months, years, and for two regions (Suisun Marsh and California except Suisun Marsh). Matchett and company examined the effect of drought on distributions of ducks by evaluating differences in spatial distributions of duck locations within and among years and between the [...]

Matchett and company (2020; see Larger Work section for citation) summarized this data set in figures E3 and E4 to compare distances moved among months, years, and for two regions (Suisun Marsh and California except Suisun Marsh). Matchett and company examined the effect of drought on distributions of ducks by evaluating differences in spatial distributions of duck locations within and among years and between the two regions. Matchett and company used this data set to summarize distances between duck nighttime (feeding) locations and primary sanctuaries used for daytime roosting. Data set columns refer to temporal and spatial attributes of locations in relationship with distance between primary roost sites and nighttime duck locations. Column 1 is Region (Suisun Marsh or California excluding Suisun Marsh) where locations were recorded, column 2 is Year class (2015-16, 2016-17, 2017-18), column 3 is Month class (October-November, December-January, February-March), column 4 is Distance to primary sanctuaries (km) referencing the distance from nighttime locations.

Purpose
We leveraged a subset of telemetry data (years 2015-18) that was collected as part of a longer-term research project to examine the possible influence of drought and habitat availability on nighttime space use and spatial distributions. Anticipated use of this data set is limited to assessment of nighttime space use by ducks during months in fall-winter in California.
