Trivia

 * She is another Female bird along with Matilda and Stella
 * She is the second female bird to simply have black eyes, after Matilda, as five out of the six birds in Angry Birds Stella are female birds with actual eye colors (light blue, green, brown, orange, and yellow).
 * Silver's design has characteristics in her physical appearance resembling the character "Silver the Hedgehog" from SEGA's "Sonic the Hedgehog" video game franchise.
