Survival and Recovery Rates of Mottled Ducks in Georgia 2006-2013

SEAFWA Journal Volume 2, March 2015

The mottled duck (Anas fulvigula) naturally occurs in two populations: one in the coastal marsh of the western Gulf of Mexico and another in peninsular Florida. A third, introduced, population occurs on the southern Atlantic coast in South Carolina and Georgia. Most mottled ducks in Georgia occur on Altamaha Wildlife Management Area, McIntosh County. In 2006, we began banding mottled ducks in Georgia using airboats at night and collected banding and recovery data from 2006 through spring 2014. We used Program MARK to estimate survival rates, Seber recovery rates, and Brownie recovery rates...

Survival and Recovery Rates of Mottled Ducks Banded in Texas and Louisiana

SEAFWA Journal Volume 2, March 2015

The Western Gulf Coast population of the mottled duck (Anas fulvigula) is dependent on the Gulf coastal marsh to complete its entire life cycle. Band recovery data can be used to monitor mottled duck populations by estimating annual survival, indexing harvest rate, and assessing movements. Band returns from hunting seasons 1997 - 2013 were used to evaluate factors influencing annual survival, recovery rates, and movements of mottled ducks in Texas and Louisiana. For banding years of 1997 - 2013, 58,349 normal, wild mottled ducks were banded and released in Texas and Louisiana. Since 2002,...
