Pittsburgh Thunderbirds Logo

Pittsburgh Thunderbirds - one of American Ultimate Disc League's expansion teams - unveiled their team logo last week.  The black and gold colors are congruent with Pittsburgh sports teams. The logo seemingly borrows from 2 existing AUDL teams – lightning bolt from Madison Radicals and the bird profile with hook-like beak similar to Montreal Royal.

While we're on the topic, the logo appears to embody "Lightning" more than 'Thunder.'
