Name: unnamed falcon

Note: trained falcon of Scarlet Witch and/or Quicksilver
At a time when the Professor Xavier sensed (through Cerebro), the presence of a powerful new menace, he wanted to recruit new members into the X-Men. Xavier astrally contacted Quicksilver and the Scarlet Witch, who were in Romania, taking a sabbatical from the Avengers. Quicksilver was testing his speed by chasing a trained falcon.
Quicksilver specifically referred to the Falcon as Wanda's falcon. He said: "My control is now as unfaltering as my speed, my sister! I can now keep pace precisely with your trained falcon!"
As far as we know, Quicksilver and the Scarlet Witch were never again portrayed as owning a trained falcon.
