Postbreeding Movements of Frigatebirds Tracked with Satellite Telemetry [PDF]

The Condor, 2006
AbstractUsing satellite telemetry, we studied the postbreeding movements of Great (Fregata minor) and Magnificent Frigatebirds (F. magnificens) at two breeding colonies in the Indian and Atlantic Oceans. After breeding failure, 67% of the birds with satellite transmitters remained on the breeding colonies and continued to perform foraging trips similar
