On the Ant Trail

While hiking a trail through Carara National Park we came upon the end of an ant army marching through the forest.  There were a number of birds there, cleaning up after the ants.  The birds don’t eat the ants; they eat the insects the ants scare up during their insistent travel through the vegetation.  This was a Chestnut-backed Antbird, which perched awhile and gave us great looks.
