Flight speeds of northern pintails during migration determined by satellite telemetry Flight speeds of northern pintails during migration determined by satellite telemetry
Speed (km/hr) during flight is one of several factors determining the rate of migration (km/ day) and flight range of birds. We attached 26-g, back-mounted satellite-received radio tags (platform transmitting terminals; PTTs) to adult female Northern Pintails (Anas acuta) during (1) midwinter 2000–2003 in the northern Central Valley of California, (2) fall and winter 2002–2003 in the...

Spring migration of northern pintails from California's Central Valley wintering area tracked by satellite telemetry: Routes, timing, and destinations Spring migration of northern pintails from California's Central Valley wintering area tracked by satellite telemetry: Routes, timing, and destinations
We used satellite transmitters to track the 2000–2003 spring migrations of adult female Northern Pintails (Anas acuta L., 1758) from California's Central Valley, USA. PTT-tagged Pintails departed during late February to mid-March, and 77%–87% stopped first in the region of south-central Oregon, extreme northwestern Nevada, and northeastern California (SONEC). Subsequently, most Pintails...

Habitat selection by female northern pintails wintering in the Grassland Ecological Area, California Habitat selection by female northern pintails wintering in the Grassland Ecological Area, California
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, 1991-94 for 196 Hatch-Year (HY) and 221 After-Hatch-Year (AHY) female pintails that were radio tagged during August-early...

Effects of backpack radiotags on female northern pintails wintering in California Effects of backpack radiotags on female northern pintails wintering in California
To test whether backpack radiotags impacted the wintering biology of northern pintails (Anas acuta), I attached spear-suture (SSU, n=82 in 1993) or harness (HAR, n=337 in 1991-1993) backpack radiotags to female Hatch-Year (HY) and After-Hatch-Year (AHY) pintails after their autumn arrival in California. I evaluated impacts of radiotags on 1) wintering population distribution; 2) flock...

Migratory birds in North America are an international resource shared by Canada, the United States, and Mexico. Ultimate population management authority in the U.S. lies with the U.S. Fish and Wildlife Service (FWS), but states participate in development of management decisions through the Flyway system. The FWS, state wildlife agencies, and nongovernmental organizations participate...

Selection of flooded agricultural fields and other landscapes by female northern pintails wintering in Tulare Basin, California Selection of flooded agricultural fields and other landscapes by female northern pintails wintering in Tulare Basin, California
Habitat selection and use are measures of relative importance of habitats to wildlife and necessary information for effective wildlife conservation. To measure the relative importance of flooded agricultural fields and other landscapes to northern pintails (Anas acuta) wintering in Tulare Basin (TB), California, we radiotagged female pintails during late August-early October, 1991-1993...
