In my research activities on Phillip Island off Norfolk, South Pacific, I have recorded an example of cross-fostering with a species of Pterodroma incubating and rearing an Ardenna (Puffinus) species.  This nest was followed (several visits then surveillance camera) from incubation until the near-fledged chick left the nest area following abandonment of breeding pair. I am seeking examples of other burrowing species doing the same.  If unpublished material of similar extent, I and my co-authors are happy to work towards a joint note in an ornithological publication.
