ECOLOGY OF FEMALE NORTHERN PINTAILS DURING WINTER IN THE SAN JOAQUIN VALLEY, CALIFORNIA by Joseph P. Fleskes A DISSERTATION submitted to Oregon State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy Complete: Novem Commencement: June Ecology of female northern pintails during winter in the San Joaquin Valley, California.

To improve understanding of pintail ecology, we radiotagged hatch-year (HY) and after-hatch-year (AHY) female northern pintails (Anas acuta) in the San Joaquin Valley (SJV), and studied.

Abstract. - Female Northern Pintails (Anas acuta) were sampled in California's three main Central Valley win-tering regions (Sacramento Valley, Suisun Marsh, San Joaquin Valley) during September-October before most re-gional movements occur and microsatellite and mitochondrial DNA were analyzed to examine population structure and relatedness. Fig. 1. Regions of California and areas within the San Joaquin Valley used by northern pintails during Sep-Mar, magnitude, timing, and causes of female pintail mortality during winter are needed to effectively manage continental pintail populations (USFWS and CWS , Reynolds et al. ).

To improve understanding of pintail ecology, we radiotagged hatch-year (HY) and after-hatch-year (AHY) female northern pintails (Anas acuta) in the San Joaquin Valley (SJV), and studied their survival throughout central California, USA, during September-March, We used adjusted Akaike Information Criterion (AICc) values to contrast known-fate models and examine variation in. 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, (Fleskes ). To determine relative importance of habitats available in the Grassland Ecological Area (GEA) to wintering female northern pintails, Anas acuta, we studied habitat use relative to availability (i.e., habitat selection) in the GEA during September through March, for Hatch-Year (HY) and After-Hatch-Year (AHY) female pintails that were radio tagged during August-early October in.
