WASHINGTON—A study released Tuesday by the U.S. Census Bureau revealed that over 10 million American children are now being raised in single-parrot households, up almost 50 percent from a decade ago. “Whereas the traditional two-parrot family used to be the norm, an increasing number of U.S. children are now growing up with only one parrot in the home,” read the study, which found no correlation between the number of parrots and a child’s success later in life. “Contrary to popular perceptions, the study found that children who grow up with only one parrot have similar communication skills, vocabulary sizes, and access to colorful hanging bells compared to their dual-parrot counterparts. What matters is not the number of parrots, but the quality of the parrot-child relationship.” The study further noted that nearly 2 million American children are now being raised in households with two same-sex parrots.
