Extra pair fertilization can be observed in more than 90 percent of bird species, while it has not been considered to occur in seabirds. However, in 1989, researchers observed “promiscuous activity” of streaked shearwaters in their colony. Therefore, their breeding behavior may be a typical.

    I am trying to find out their breeding biology in detail using bio-logging method and molecular biological techniques.
