Abstract

Information on wing-molt timing is summarized for three southern-breeding taxa of Oceanites storm petrels: Wilson’s Storm Petrel O. [o.] oceanicus, Fuegian Storm Petrel O. [o.] chilensis, and Pincoya Storm Petrel O. [o.] pincoyae. Timing of molt in seabirds is often poorly known for breeding adults and differs in relation to migration distance, starting sooner in shorter-distance migrants. The trans-equatorial migrant Wilson’s Storm Petrel has a novel, complete wing molt added into its first cycle, something lacking in the shorter-distance migrant and more sedentary Fuegian and Pincoya storm petrels. More data are needed to establish wing-molt timings with respect to age and breeding status in Pincoya and different populations of Fuegian Storm Petrels, which may help elucidate taxonomic relationships.
