Phenology: Mourning Dove Copulation Log

It's a copulation "log" in two ways: (1) that it is my logging of a copulation event between two Mourning Doves (Zenaida macroura), and the fact that (2) the copulation literally took place on.....a log!

So, the event begins down at the old make-out spot with a single male, checking out the scene.........

His patience pays off....

Then, the showing off begins....

 ....and continues.....

Then, the preening of eachother begins....

The girl also decides to show off a bit....

This is followed by alittle more co-preening......

....and more.....

The picture says it all, I should think!

....next the cuddling.....

But eventually, that inevitable awkwardness sets in....

They apparently try to ignore eachother with alittle self-preening. Perhaps hoping the other will get the hint and leave.  They both work pretty hard at putting out the "take a hike" vibe, but it doesn't seem to work.

....but neither is willing to give it up.....

For a moment, it appears they might confront the elephant in the room....but the male gets the wrong idea.

...and so it's back to pretending the other isn't there.....

Finally, they put a bit of space between themselves.....

...and the male starts to plan his exit strategy....

They both must have left, because that was the last picture of either!

Notes on Mourning Dove reproduction.  In our neck of the woods it is common for this species to reproduce from April through September, so this is a tad early compared to a "normal" year.  The reproductive behavior outlined above is typical, although there is often much head-bobbing, etc. that doesn't really come out in still photos.  Although my commentary above gives the impression that they don't want to be around eachother after copulation, the Mourning Dove is actually a seasonally monogamous species (they remain in the same pair during a single nesting season).  So, these two will probably be together for much of the rest of the season, and there is even some evidence that this species will re-pair with the same individuals in subsequent years.  The co-preening behavior and the self-preening behavior outlined above is typical of this species during pair-bond formation and copulation.  Nests are often a loosely aggregated bundle of materials (pine needles, etc.) that are placed in dense foliage.  Females usually lay one to two eggs at a time.
