Good man! I put out 4 more yesterday. I added plexiglas entrance reducers to thwart the sparrows nesting ability. I reduced all the openings to 1 1/8".
They pecked away at the opening on one of my wren houses and got it big enough to get inside. It's been fun watching them try to get through the plexiglass reducer. They just can't!
Hopefully the wrens, chickadees, nuthatches and titmice will make use of them.
My bluebirds are doing an admirable job of defending their nest box. We sere sitiing out enjoying the sun yesterday and watching them dive bomb squirrels, grackles, starlings, sparrows and even a crow.
They've got a full nest built but no eggs yet. Still not enoug bugs and such around yet I guess.
