Dennis et al.,

The claim that some neotropical migrants breed twice in a year, once in the
US and a second time in western Mexico, is an intriguing one. However, with
all due respect to Sievert Rohwer and Keith Hobson, who are both highly
experienced and respected ornithologists, I won't be convinced until they
have evidence from leg-banded birds that nesting has occurred in both areas
in the same year-- something that has not yet been shown. Evidence from
brood patches, mineral composition of feathers, etc., rates as
circumstantial evidence in my books.

Always the skeptic!
