Give a birdhouse some privacy

Active birdfeeding areas make terrible nesting sites  - too much going on. Areas near birdbaths are "no-nest zones" too. Nesting birds, whatever the species, tend to be very territorial and dislike the constant activity around a birdfeeder or birdbath.

You may see birds near a feeder but that doesn't mean they're nesting there.  Trees and shrubs near feeders are merely staging areas  - intermediate perches to see if a feeder or birdbath is safe, or the food's promising.

A nesting bird doesn't want to be scrutinized for even a second. She (usually it's a female) is terribly vulnerable and the nestlings are helpless.(That's also why most female birds aren't brightly colored)

Wrens have a tough time making up their minds

Before selecting a mate, a male Wren locates four or five possible nest sites, and seeds each of the areas with lots of sticks and other nest-building materials. Then he chooses a mate. The mate/female then chooses the best nesting site and builds the real nest, using the materials put there by the male.

She'll lay 4 to 8 eggs but, like all birds, won't begin sitting on them ("incubating") until the last one's laid.  That way they're all hatched at the same time.
