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.

The Central Valley Bird Club (CVBC) is dedicated to the study of the distribution, status, ecology, and conservation of birds in the Central Valley of California. SOCIAL LINKS CV Birds on 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.

Ramey, Joseph P. Fleskes, Joel A. Schmutz, Michael J. Yabsley, Evaluation of blood and muscle tissues for molecular detection and characterization of hematozoa infections in northern pintails (Anas acuta) wintering in California, International Journal for Parasitology: Parasites and Wildlife, /, 2, ( In addition, food resources (both relative and absolute abundances) were lower during winter than summer.
From these data I infer that the intensity of interspecific competition and its effect on waterfowl community structure is seasonal, with greater resource limitation and, therefore, resource partitioning during "lean" winter months than. The San Joaquin Valley is a sediment-filled depression, called a basin, that is bound to the west by the California Coast Ranges, and to the east by the Sierra Nevadas.
It is classified as a forearc basin, which basically means that it is a basin that formed in front of a mountain range. The San Joaquin Valley (/ ˌ s æ n hw ɑː ˈ k iː n / SAN whah-KEEN) is the area of the Central Valley of the U.S.
state of California that lies south of the Sacramento–San Joaquin River Delta and is drained by the San Joaquin comprises seven counties of Northern and one of Southern California, including, in the north, all of San Joaquin and Kings counties, most of Stanislaus.
Pintail Flight Paths As part of a 3-year study of northern pintail winter- ing 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 Au- gust and September, (Fleskes ). We examined carcass composition and proximate food composition of ruddy ducks (Oxyura jamaicensis), northern shovelers (Anas clypeata), and northern pintails (Anas acuta) wintering on agricultural drainwater ponds in California during – Lipids varied seasonally in northern shovelers and northern pintails.
Protein did not fluctuate except in ruddy ducks whose protein mass increased. The Central Valley of California (), USA, is one of the most important waterfowl wintering areas in the world (BellroseGilmer et al.
).Half or more of the northern pintails (Anas acuta; hereafter pintail) in North America migrate to and winter in California, arriving as early as the first week of August and remaining through March (BellroseAustin and Miller ).

AprJun Adult (i.e., after first calendar year) female pintails (n = ) were captured and radio-marked during late August through early October of each study year at three wetland locations; the Colusa Basin in the northern CVC, the Suisun Marsh just to the west of the CVC, and the Grassland Ecological Area and Mendota Wildlife Area in the southern CVC.
Northern pintail Anas acuta (hereafter pintail) populations wintering within Suisun Marsh, a large estuarine managed wetland near San Francisco Bay, California, USA, have declined markedly over the last four decades.

The reasons for this decline are unclear. Information on how hunting and other factors influence the selection of vegetation types and sanctuaries would be beneficial to manage. San Joaquin Valley, valley in central California, U.S., the southern part of the state’s vast Central Valley.
Lying between the Coast Ranges (west) and the Sierra Nevada (east), it is drained largely by the San Joaquin River. The valley is one of the most productive agricultural regions in the.Pintails were radio tagged during August - early October at MWA (n = ), other San Joaquin Valley areas (n = 27), or Suisun Marsh (n = 2).
Before duck hunting season (i.e., Prehunt), pintail distribution at MWA generally tracked marsh flooding although distribution was more concentrated during the .A California Chapter of the National Audubon Society Serving the communities of Stockton, Lodi, Tracy, Manteca, Escalon, Ripon, and Lathrop--All of San Joaquin County.
