Movements of American White Pelicans Breeding at Medicine Lake National Wildlife Refuge, Montana

Metadata Updated: January 29, 2020

Medicine Lake National Wildlife Refuge (MLNWR) in northeastern Montana is home to one of the largest colonies of American white pelicans in the United States (Sidle et al. 1985). This colony has been in existence since the late 1930s, and the number of breeding pairs has grown steadily (current 10-yr average = 3700 nests) (Madden and Restani 2005). Despite the presence of this significant “trust” resource, managers at MLNWR possess little information on the ecology of these birds and therefore are unable to identify and address management concerns or conservation threats.

Beginning in 2002, satellite telemetry and banding was employed to monitor the wide-ranging and local movement of pelicans breeding at MLNWR. Satellite telemetry is the most cost-effective and feasible method to monitor wide-ranging foraging movements of birds (Rodgers 2001). Another advantage of satellite telemetry is that birds can be tracked regularly during migration and in wintering areas, so a complete picture of annual movements and use areas is gained. Determining the origin of wintering pelicans is important because of the growing conflicts with the aquaculture industry: simultaneous increases are occurring in both catfish farming along the Gulf Coast and in the continental pelican population (Belant et al. 2000, Sauer et al. 2004). Identifying breeding ground origins of depredating pelicans and their winter use areas along the Gulf Coast will aid management of this emerging conflict.

Also included, as separate digital holdings, are the tabular data sets used in completion of the aforementioned report. -2002 Banding Schedule -2003 Banding Efforts -2004 Banding Efforts -2005 Banding Efforts + Notes -2006 Banding Efforts
