Here is an interesting video about some the Raven family members. They are quite productive. Enjoy! Maybe that is how they were able to accomplish what this verse mentions:
And it will be that you shall drink from the brook, and I have commanded the ravens to feed you there.” (1 Kings 17:4 NKJV)
Also, read Dr. James J. S. Johnson’s Article “Clever Creatures: ‘Wise from Receiving Wisdom’”.
