I have had a pair BB’s all winter long, a first for me as far as I know, and they have been checking out the front box for weeks going in and out often and defending it last week against a starling and a Carolina Wren. Well this past Thursday I saw mama taking in nest building material, but only saw her in there today. It has turned cold again here, below freezing so maybe that has something to do with the halt to the nest construction.
I also have an extra male, I think one of the off spring of this pair from last year. I hope he finds a mate and takes up residence in my second box.
Happy Blue Birding Everyone,
