This depicts a Steller's jay in the process of retrieving some of his cached acorns...but one "got away"! Forgotten acorns buried by jays are one of the oak tree's most effective means of seed dispersal. Otherwise ones that fall and sprout directly below the parent tree typically die.
I built a clay model based on photos of Scrub jays to get the pose and perspective, took photos of my own yard dirt, and then went around hunting in my yard for oak sprouts to dig up (found a bunch actually).
