Male and female cactus wrens mate for life and are similar in appearance. They protect their established territory (where they live throughout the year) and aggressively defend their nests from predators. Cactus wrens also destroy the nests of other bird species, pecking or removing their eggs. There are many symbols that have been attributed to the wren by the Celts, some of which include creative, quick, active, free spirited, friendly, determined, light-hearted, quick witted, and always willing to share. Wren reminds us of the medicine of using what is available to us and shows us the most effective ways to build in our own circumstances and environment.
