Chicks' sex isn't just a matter of chance
In 1939, a man walking his dog in Brooklyn noticed Hollywood finches for sale in a store. The reddish-brownish seed eaters are native to the dry Southwest, including Southern California. A 1918 law was supposed to have protected such North American migratory birds from capture and sale as caged birds—though the rule was seldom enforced. The dog walker complained to authorities, and this time they began a crackdown. When some store owners around the city realized that they would get in trouble, they opened the cages and let the evidence fly away.
