Using Decoys to Attract Seabirds Biologists are placing seabird decoys on Coronado Islands located in the Baja California Pacific Islands off of Mexico. Decoys are wood models that are shaped and painted to look like seabirds. They are used as a “social attraction” technique that tells certain seabird species that this is a good place to nest. Other techniques include broadcasting seabird sounds and use of mirrors. The mirrors make the decoys appear more numerous and reflections of live seabirds give the appearance of movement. MSRP is funding this effort to restore Brandt’s and Double-crested Cormorant populations that nest on these islands.
