Survival of adult female northern pintails in Sacramento Valley, California Survival of adult female northern pintails in Sacramento Valley, California
North American populations of northern pintails (Anas acuta) declined between 1979 and the early 1990s. To determine if low survival during winter contributed to declines, we estimated winter (last week of Aug-Feb 1987-90) survival for 190 adult (after hatching yr [AHY]) female radio-tagged pintails in late summer in Sacramento Valley (SACV), California. Survival rates did not vary by...

Changing patterns of goose harvest on California public hunting areas Changing patterns of goose harvest on California public hunting areas
We summarized hunter visits, success, and the magnitude and species-subspecies composition of tho goose harvest recorded on California public hunting areas (PHAs) during 1950-89. Of six geographic regions, the Northeast accounted for the largest portion of the PHA harvest (55%); most of the remainder occurred in the Sacramento (30%) and Imperial (10%) Valley regions. Harvest, hunter...

Survival and other observations of adult female northern pintails molting in California Survival and other observations of adult female northern pintails molting in California
Survival rates of nine adult female Northern Pintails (Anas acuta) that became flightless after being radio-marked in the Sacramento Valley, California in August 1987-1989 were estimated. Seven of the radio-marked pintails molted in the Sacramento Valley, a nontraditional molting region, and two flew 280 km north to the Klamath Basin to molt. Molting marshes were dominated by emergent...
