Oh, my goodness – Tammy & Fred – I read this incorrectly and yes, it calls for 1 1/4 to 1 3/8″ for the wire opening!! We have made 3 of these and I checked the one closest to house and it is 1 1/2″ so I’m assuming the rest are, too. I can’t believe we both read this wrong. We will correct this problem by adding another wire just below the present one, which will be no problem. THANK YOU, THANK YOU, BOTH! It is possible the 1st one we made was correct – I haven’t checked yet, but the blues did fledge 5 birds from it last year.
