The most intreaguing and un-explained aspect of the life history of this species is its regular inland occurrence (see distribution). This means that 'Fuegian' storm-petrels likely breed inland to some extent. If this is true, and nest sites are discovered, it would open up a whole new perspective on storm-petrel breeding biology, and may well contribute to solving other inland storm-petrel mysteries, such as those of Ringed, Elliot's, and Markham's Storm-Petrels.
Given this species's wide range oceanic range and huge population, it seems possible that studies on Wilson's Storm-Petrel could be a good indicator of the changing ocean temperatures, salinities, and pH levels.
Whether or not 'Fuegian' Storm-Petrel (O. o. chilensis) is it's own species or not is also in question. This could be determined thorough studies of genetics, vocalizations, and other aspects of the taxa's biology.
