It means he gets two attacks. Each of those attacks get +5 on the attack roll.<br/>Each attack that hits then deals 1d4-2 damage (a minimum of one damage, not 0 by the way; every successful attack deals at least one damage no matter what.)<br/>You need a full attack action in order to make both attacks, though. Which the bird should get this round (last round it used a move action to get to the robot)
