Use your mouse to control the direction of the flock! You can break open the glowing orbs to release more birds. Some orbs will need to be hit multiple times before they release more birds. If it seems like it is taking a while to break open the orb, try collecting more birds and return back with a bigger flock. If the orb seems to disappear before the birds break free, use your flock to see where the orb is hiding.
