GPS-marked waterfowl and harrier locations from January 2019 through August 2020 in western North America

These data describe bird locations obtained from backpack-mounted GPS loggers on several species of waterfowl and of Northern Harrier captured and marked in California and Oregon. Both cursory and opportunistic quality control have been performed on these data during the course of data collection. These methods include identification of mortalities and translational errors in digital transmission of data resulting in gross positional or temporal errors such as transposed digits.
