“Birds are not as loyal to their partners as you might think, with divorce, child abandonment and remarriage a common part of birds’ life,” a new book has shown. Author and biology professor Bridge Stutchbury, dispels the love-bird belief that birds pair up for life. “In terms of the top 10 beliefs about birds, the lasting pair bonds that we think about, do occur in some birds, but in most of the little songbirds that we studied, no,” the professor from York University in Toronto said. The divorce rate among greater flamingos is 99 percent.

Stutchbury’s book, The Private Lives of Birds, based on 20 years of research from radio filming and DNA testing shows male Acadian flycatchers fertilize(使受孕) females far away from their home nests, “ The main discovery is that so many birds do divorce for what humans would describe as selfish reasons,” Professor Stutchbury said. She noted that females may seek out males that are more colorful and better singers, or look to “step up in the world” and move to areas that are safer and have more food. “Females are looking for the highest quality male so that their children will be of high quality,” she added.

Professor Stutchbury said shorter summers may drive females to leave their nests before their young are fully grown up so they can quickly find new mates（配偶） and lay more eggs, leaving the males to feed the hungry chicks on their own.

Males can double their success in producing children by fertilizing neighboring females, but only “mates” care for the young, and some are none the wiser. “  They can’t tell when the egg comes out and whether it’s theirs or not,” She said. “They have no way to know.”

Divorce is surprisingly common among birds, and most live with one partner for only a few months or years. Divorce rates range from 99 percent in the greater flamingo to zero in the wandering albatross(信天翁).
