Next, ask yourself if electricity is a form of energy. If it's energy, then electricity is not the movable charges. Instead, electricity is made of invisible electromagnetic fields, and it doesn't wiggle back and forth within the AC cables. Instead it can only exist in the space outside the wires, and not within the metal.
Cardinal Color: One of the first and most obvious qualities about the cardinal is his color. Cardinal red is so called because it is one of the three primary colors. The primary colors are red, blue and yellow. All other colors are a combination of these three basic colors. That the visual spectrum begins with red hints at the importance of the cardinal, beginning with his powerful visual presence.
Note that the adult male summer tanager is also bright red, but it lacks both the crest and the black face. In the Southwest, the northern cardinal overlaps with the very similarly shaped pyrrhuloxia, but note their color differences. Female and immature pyrrhuloxias are very similar to female and immature cardinals.
