I was gifted this magnificent belt that features the logo of several Marvel characters, specifically members of the Avengers. From top to bottom: Nick Fury/S.H.I.E.L.D., Hulk, Iron Man, Thor, unknown, Captain America, Hawkeye, and Black Widow. My question is: what character is represented by the image between Thor and Captain America? I think that it could be Scarlet Witch or Falcon, my brother thinks that it's Ant-Man. Who is it?
Based upon the results of a few Google searches, that symbol appears to be one of several used for Falcon. See "New Disney Cast Member Pin" (the same pin also is offered at a pin trading database); also see (less authoritatively) the MCU Wiki and, oddly, animal information site Animalia Life.
Here's a screenshot of the first linked webpage, in case it ceases to exist.
