Interpretive Summary:

Technical Abstract: During the past seven consecutive years (1999-2007), aerial surveys by fixed-wing aircraft were conducted to monitor and quantify the wintering cormorant numbers. In addition, during the past two winters 2005-2006 and 2006-2007, 20 double-crested cormorants were captured, leg banded, and fitted with global positioning system (GPS) satellite transmitters and another 18 cormorants were fitted with radio transmitters and remotely monitored to determine movement patterns within the Mississippi Delta and their respective roost sites. Of the 20 GPS satellite transmitters, only 4 birds’ transmitted locations during their spring migration for each year, and only 2 birds’ transmitted locations for a full year. The information gained from this study to determine movement patterns will assist catfish farmers within the Mississippi Delta as well as the policy- and management decisions regarding this species.
