Clean Break

Human parents generally live year-round with the same mate and maintain ties with their children throughout their lives. House Wren young seldom return close to the territory where they grew up, and after they disperse there is no evidence that they recognize their parents, or vice versa. Moving away from their natal territories may help prevent parent-offspring matings.

For the first 5 or 6 days after the eggs hatch, the mother spends most of her time keeping the chicks warm while the father provides most of their meals. All that work may be what prompts the female to leave the family. They share feeding duties more equally during the next week or 10 days, until the young leave the nest. Producing a second batch is easier if she skips the last grueling week or two of provisioning fledglings. She can recharge her batteries by moseying off and, while on vacation, looking for a new Casanova.

The bonds between House Wren mates may seem tenuous, but they last exactly as long as they need to.
