In some cultures, seeing a bird perched atop the highest limb on a tree is viewed as an omen of magnificence, hope, peace and even prosperity. Of course, other cultures glance and consider it nothing at all, and some cultures even consider birds spiritual beings with varying degrees of omen-ship that sways good or bad depending on the species.
I think this robin was simply scouting for a nest location while taking advantage of the remaining light from this blazing late-winter sunset. Maybe armed with a little bit of that “hope” in its wings as it prepares for the next cycle of parenthood.
