Summary

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.

Description

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.

Use limitations

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.

Supplemental information
METHODS Highway 152 Zones I delineated 5 zones along Highway 152, using road intersections or waterways to mark the boundary between adjacent zones that contained different levels of urbanization. Listed from west-to-east, the zones were: 1) WEST, a 2.7-km zone from Volta Road to Los Banos Creek on the west border of Los Banos; 2) CITY, the 5.3-km Los Banos zone; 3) EASTCITY, a 1-km zone from Ward Road on the east border of Los Banos to San Luis Canal; 4) NEAREAST, a 1.3-km zone from San Luis Canal to Sante Fe Grade; 5) FAREAST, a 9.7-km zone from Sante Fe Grade to San Juan Road (Fig. 1). I used photographs that I took during October 1992 flights and a Geographic Information System to estimate urbanization, measured as the percent of each zone that had buildings within 100 m of Highway 152, and to estimate the distance from Highway 152 in each zone to the nearest flooded area. Pintail Flight Paths As part of a 3-year study of northern pintail wintering ecology, 58 Hatch-Year (HY) and 65 After-Hatch-Year (AHY) female pintails were captured, radiotagged, and released in the San Joaquin Valley, California during August and September, 1992 (Fleskes 1999). On 4 November, 11 November, and 9 December, 1992 (all hunting days with clear evenings and days, dates selected because work schedules permitted and numerous radiotagged pintails were flying daily to the SGL), I used truck-mounted directional antennae to determine (Fleskes 1999) the afternoon location of all radiotagged pintails that were present in the NGL and EGL. Technicians stationed in tracking vehicles at the borders of the 5 Highway 152 zones scanned for all radiotagged pintails until an hour after sunset and determined the zone over which each pintail that went to the SGL flew. I continued monitoring all birds, and when signal strength decreased and movement stopped for more than 1-2 minutes, I triangulated the initial landing location for those that landed in the SGL. I used the ARC/INFO (Environmental Systems Research Institute, Incorporated, Redlands, California, USA) computer program and a Geographic Information System with digitized maps to plot the NGL or EGL starting location and the SGL ending location. If the line connecting the starting and ending location crossed in the Highway 152 zone where I observed the pintail crossing, I assumed and plotted a direct flight line. If the line connecting the starting and ending location crossed outside the Highway 152 zone where I observed that the pintail crossed, I plotted a Highway 152 crossing point as the midpoint of the known crossing zone (except in one instance where I was able to determine the actual crossing location).
