[Bluebird-babble] House Wrens in bluebird box

[Melissa Dove]

We have bluebirds incubating 5 eggs in one next box on the corner of our 40 
acre property and I just discovered over the weekend that house wrens were 
making a next in a bluebird box close to our home.  Do I need to worry that 
the house wrens may attack the bluebird eggs?  They are probably at least 
1/8 of a mile from each other.

Thanks,
Melissa
