Our home is a giant nest box...

We have a Mourning Dove (Zenaida macroura) nesting on roof bracket at the corner of our front porch.  Its nest is on top of an old American Robin nest on top of another American Robin nest.  Mourning Doves are not the best nest builders.  Building on top of an older nest is a common strategy.  In fact a Mourning Dove nested in the same location last summer.

Some of their nest material choices are questionable.  Like using a Honey Locust branch with 2 - 3 inch thorns as part of the nest lining...

So far this year we have had two nests of American Robin chicks (on another roof bracket) and one nest of House Finches (in a hanging fern) fledge from our house.  Right now, in addition to the Mourning Dove, the House Finch pair is building another nest in the other hanging fern!
