Actually, its not weird at all. Manx commonly winters in southern Argentina
and there have been records on the Chilean side of the Straits of Magellan.
Like Dennis mentioned, all it takes is for these birds to go north on the
wrong side of South America. Greater Shearwaters also are found around the
Straits of Magellan at times. A weird record, however, is that of Little
Shearwaters off the coast of Chiloe Island in Chile. Rather than strays,
this implies that they may breed nearby- odd. It does affirm that the
pelagic area is the undiscovered frontier in birding, we have a lot to learn.
