Mourning Dove nest on ground with chicks

Recently there was a discussion partly online about Mourning Doves nesting on the ground, especially after numerous finds on BARE ground in Hidalgo Co.  Several profess having ever seen the species do this.  So this evening Paul Sunby and I were out in Edwards Co. and flushed a bird off the side of a road cut.  Here is a photo of the nest with 2 chicks on limestone.  The exception here being instead of bare ground in the case of the Hidalgo Co. birds, the parent of these chicks actually constructed a nest of sorts.
