Mississippi Alluvial Valley Forest Conversion: Implications for Eastern North American Avifauna

Because bottomland forests of the lower Mississippi Alluvial Valley (MAV) are valuable as breeding, wintering, and en-route habitat during migration, we investigated the impact of changing land uses in the MAV on avian abundance and diversity at the local and continental scales. Checklist inventories from 5 studies conducted in the MAV during 1985-1992 confirmed that bird species that occur in the MAV represent a substantial proportion of the entire avifauna of eastern North America (ENA). Of 236 landbird species reported for ENA, 200 (85%) occur in the MAV; we recorded 149 landbird...


Habitat Use by Eastern Wild Turkey Hens in Southeastern Louisiana

Seventeen female eastern wild turkeys (Meleagris gallopavo silvestris) were fitted with transmitters and monitored continuously during March 1984-May 1985. Mean home range for 4 hens that survived the 15-month study period was 677 ha. Adult (i = 66 ha) and subadult (i = 149 ha) home ranges differed (P < 0.05) during spring and may be related to nesting activities. Mean home ranges during summer, fall, and winter were 124,402, and 254 ha, respectively. Average distance traveled in 24 hours did not differ (P > 0.05) between age classes or among seasons. Subadults and adults differed (...
