Shearwater Chicks are Hatching !

Over two thirds of the 64 nests we have been monitoring since late July have hatched chicks already and we are getting ready to start tagging the parent wedge-tailed shearwaters by the end of this week. We wait until the chick has been left unattended by the parents at the nest before we tag the adult birds. The parents will provision the chicks until the second half of November, when they disperse from breeding colonies.

About This Project

Wedge-tailed Shearwaters leave Hawaiʻi at the end of the nesting season (November) and return in spring (March - April). During their winter dispersal, shearwaters are threatened by fisheries and marine debris. Yet, we do not know where they go and whether their migrations shift in response to changing ocean conditions. Mapping their year-round distributions and the threats shearwaters face at sea, will facilitate the broader conservation of this species throughout their life cycle.
