First Evidence For A Second Breeding Season Among Migratory Songbirds
excerpts from above:
Quote:
Biologists for the first time have documented a second breeding season during the annual cycle of five songbird species that spend summers in temperate North America and winters in tropical Central and South America...
Quote:
...the researchers found individuals from five species -- yellow-billed cuckoos, orchard orioles, hooded orioles, yellow-breasted chats and Cassin's vireos -- that were breeding rather than molting.
