The purpose of this dataset is to identify important pintail flight corridors in the Grassland Ecological Area along Highway 152 where increased urbanization is projected, provide baseline flight path information necessary to evaluate impacts of future urbanization and other landscape changes, and provide insight into how urbanization and wetland habitat impact pintail flight paths.
North-south flight paths of radio-tagged female northern pintails were monitored in a section of Highway 152 near Los Banos, California during 4 and 11 November and 9 December 1992 on their way from daytime roost sites in the north to nocturnal feeding sites in the south part of the Grassland Ecological Area. The dataset includes spatial and temporal information of 53 flight paths from 42 different pintails. Accuracy of individual data fields has been reviewed. Data collection is completed.

Positional accuracy of individual locations is limited by: uncertainty in telemetry locations (observer error) and possible data entry errors. Although, all reasonable attempts have been made to limit these factors, positional accuracy for any individual point should not necessarily be considered minimal. The appropriateness of multiple scales of inference, is the end-users responsibility to justify and the originators assume no responsibility for incorrect or misleading uses of this data.
