Dear Friends:

study of a nestWhen J.J. Cardinal’s customer, Rodger Bloomfield, Linden, MI, was giving his nest boxes their seasonal cleaning, he discovered two distinctive nests in one box. The first nest was clearly an eastern bluebird’s nest and piled high atop the bluebird’s nest was the nest of a house wren.

House wrens, though small in size, are quite aggressive and will often take over even an established nest as is shown here:

1) The nest as first seen;
2) The nest being broken down revealed eggs characteristic of the house wren: mauve in color with sparse cinnamon speckles;
3) Upon closer inspection 4 bluebird eggs were found;
4) The wren may have had as many as eight eggs and only five hatched or perhaps the wren abandoned the nest site also. Thank you for providing this interesting series of photographs Mr. Bloomfield.
