The robin-themed song, Rockin' Robin, is on my mind because I recently encountered a "rockin' robin" when I was in The Ramble portion of Central Park and came upon a lone American Robin who was not rockin' in the treetops but rather was rockin' on the ground as seen in the set of pictures atop this entry.
It is also on my mind because today is Holy Thursday and I'm thinking about an answer to a question (What is the significance of robins in the bible?) re this avian creature and Christianity.
One web-answer to the question states this: "There is no mention of a Robin in the Bible, what I believe your friend was alluding too is the ancient story that a Robin perched on the cross when Jesus was dying and pricked itself on a thorn and that is how Robins have a red breast."
Another web-writer states: "One day, about 2,000 years ago, one of the brown birds was perched on the branch of a tree when it saw Jesus being pulled through the streets of Jerusalem, bent under the weight of a heavy cross. A crown of thorns pierced His head making it bleed. The small brown bird felt sorry for Him and flew down. To ease the pain a little it plucked out a thorn from His head. On the thorn was a drop of blood which fell onto the breast of the small bird. That red stain is there to this day. As thanks for the efforts of that one small brown bird to ease Christ’s suffering, all the small brown birds, male and female, were given a red breast by God."
These stories are probably fake news in terms of specifics, for as someone (who identifies himself as Corey) proclaims, "If there are robins in the Bible, they wouldn't be the same genus as robins in North America (or Australia). I'm not sure how far East Erithacus is distributed, but that'd be the genus most likely to appear in the Middle East. A related group of birds are called thrushes."
Rather these theories re the coloring of a robin's breast are factual, the idea of a little bird easing suffering is certainly true. Many people who observe nature, especially the "little things" within it — such as little birds — are eased of some of their suffering from trials and tribulations (and please know that I'm not comparing their sufferings to the suffering of Christ).
Whatever your individual thoughts may be, it's interesting to ponder the idea that a robin's red breast can ease suffering.
