I finally was able to the see the layer cake of nests that were built within it that as far as I know successfully produced three families of birds, each of a different species between February and early July...I have a series of this layer cake on the blog (below)...I have never had such a productive nest box ...And I do not not what its secret is. -- Brush Freeman Independent and affiliated Field Biologist 361-655-7641 http://texasnaturenotes.blogspot.com/ Finca Alacranes., Utley,Texas The greatest musician of all time is mother nature.
