Tweeters,



The discovery of a south bound breeding site seperate from the northern breeding site in Neotropical migrants by Rohwer et al. is a remarkable find. However, it should be noted that this phenomena has been hypothesized for many years in Sedge Wrens in eastern North America with much evidence to support it.



For those interested I'd recommend reading:



Bedell, P. A. 1996. Evidence of dual breeding ranges for the Sedge Wren in the central Great Plains. Wilson Bull. 108:115-122.
