Perch or no perch???

Hey there, the bird houses continue to develop.  The first batch of 14 went really well but the question of having a perch or not was on the mind of birders.  In an attempt to make a nice birdhouse that birds will use and folks will want in their gardens we are trying new things.  If you are a birder and have thoughts...I'd be glad to her them.

This past weekend we did the Zilker Garden Show in Austin texas.  Here is a shot of the two houses side by side.  In the shot you can see the perch or no perch option and the smaller hole size in the no perch option.  The smaller hole size is what we are currently using on all the bird houses.  After the drying and firing shrinkage the hole is not at about 1" to 1 1/8".  The birders like it better...time will tell what the birds think.
