Well, my bluebird pair have built a second nest in the same box as the first and have deposited their first egg this morning – ANOTHER WHITE EGG LIKE LAST BOX. Seems to indicate that once a female lays white eggs they will continue to do so in the future. I don’t really care, but it is interesting and new. They checked out a different box for a while but ended up with the same box as last year. I will be looking for egg #2 tomorrow.
P.W. We had a VERY hot day today – in the upper 90’s – so hubby and I put on the sparrow spooker and heat shield like we did for last box. They seemed to accept it very well, but will keep an eye on the box tomorrow morning.
