At least five species of birds that breed in North America in spring or summer breed again, in Mexico, en route to their southern wintering grounds, say University of Washington-led researchers. Such "migratory double breeding" had not been documented in the Americas before. The loss of Mexican nesting grounds may explain some birds' population declines.
