Survival of female northern pintails wintering in the Playa Lakes region of northwestern Texas
Article Abstract:
Winter survival rates, documented periods of mortality and identified possible causes of mortality for 159 and 168 radiotagged female pintails was investigated in several winter and migration areas including Playa Lakes Region (PLR) of northwestern Texas during 23 October 2002-18 February 2003 and 10 October 2003-18 February 2004, respectively. It was found that there was a positive linear correlation between body mass at time of capture and survival rates during winter for 2003-2004 with lower survival probably due to fewer wetlands being available in the PLR.

Survival of common goldeneye Ducklings in interior Alaska
Article Abstract:
The first-known estimates of duckling survival for common goldeneyes were provided at the northern limit of their range in Interior Alaska in 2002 and 2003. It indicated that precipitation had a consistent negative effect on duckling survival in both years across models, whereas duckling age did not explain much of the variation in daily survival rates.
