Divorce in the Canary Islands Stonechat (Saxicola dacotiae)
2005
Illera, Juan Carlos
I report the first case of divorce for the Canary Islands Stonechat (Saxicola dacotiae), an endemic bird species of the semiarid island of Fuerteventura (Canary Islands, Spain). I studied 72 pairs during three breeding seasons (2000––2001, 2001–– 2002, and 2002––2003). In 2001––2002, a female divorced after a successful first nesting. This female settled in a neighboring territory where the owner was unpaired, built a new nest, and laid four eggs. The low rate of divorce (1.4%%) suggests that unforced mate changes by Canary Islands Stonechats are rare.
