Male Marsh and Sedge wrens are famous for piercing other wren eggs, even their 
own. It is one of the suggested reasons for building more than one nest 
structure by the females. House wrens are poor choices for yard nesters as they 
will pierce every egg that is weak enough for their bills to hole.

I think that Laurie's idea is a good one.  All of the other
cavity nesting songbirds, including bluebirds, compete
with each other--why not wrens?

Wrens have the habit of "piercing" and removing
eggs of bluebirds and Tree Swallows, so why not
other wrens?
