the bird sings on step 33 (btw, the middle step is 25 (33 - 8))
he walks down 12 steps and picks up a pebble
33 - 12 = 21
He takes one step up and tosses the pebble over his left shoulder
21 + 1 = 22
Now, he walks up the remaining steps three at a time which only takes him 9 paces
3 x 9 = 27; 27 + 22 = 49

Duh! I started off with x/2 when it should have been (x+1)/2!
