There are about ten thousand living species, more than half of which are passerine, or "perching" birds and the United States is home to 1107 different species. Birds are social, communicating with visual signals, calls, and songs. Evidence suggests that songbirds evolved 50 million years ago in India, Sri Lanka, Australia, New Zealand, and New Guinea, before spreading around the world. Thankfully the birdwatchers of the world, most of us, can really enjoy their beautiful colors in this 24"x 30" 1000 piece puzzle. Artist: Wendy Russell
