Use of habitats by female northern pintails wintering in southwestern Louisiana
Article Abstract:
The breeding population of pintails was 39% below average in 1996, and winter habitat conditions have been positively linked with annual changes in pintail breeding populations. The use of habitats by female pintails in south west Louisiana was investigated with the use of radiotelemetry, to determine diel use of refuge and non-refuge sites, and test the Tamisier hypothesis that the use of refuges is not linked to hunting. This was rejected when it was found that diurnal use of refuges was much higher during hunting seasons. Fallow and rice agriculture was used extensively by females, with the habitats representing 68-93% of use at night, and this is an important consideration in the management of wintering pintails.

Direct recovery rates of lesser scaup banded in northwest Minnesota: sources of heterogeneity
Article Abstract:
The heterogeneity of direct recovery rates in hunter-killed lesser scaup was investigated. To this end, the hypothesis of condition bias in lesser scaup banded in northwest Minnesota was tested. Results showed that body mass of recovered birds at capture was lower than those that were not recovered. Logistic expression findings also revealed that the probability of recovering a bird decreased as body mass increased and that this probability of recovery increased with the date of first capture.

Survival of female northern pintails wintering in Southwestern Louisiana
Article Abstract:
Radiotelemetry was used to estimate survival rates of female pintails wintering in southwestern Louisiana. Female survival during hunting was lower than during nonhunting seasons. Survival did not differ in relation to winter or condition, while hunting mortality did not differ in relation to winter, condition or region. Hunting mortality rates if pintails in southwestern Louisiana remain high despite conservative hunting regulations.
