At Chloe's house, you reach a point where you must go downstairs for breakfast. Before talking to Chloe's mom about breakfast, find the bird perched on a cabinet in the living room. Open a window on the wall to the left, then "scare" the bird (the option appears when you are close to it). It will fly to another perch. Scare it a second time, and it will fly out the window. (If the window isn't open, it will fly to a third perch, and next back to it's original point).
Once the bird is outside, go outside and locate it on a fence above a large kid's drawing. Take a picture when prompted to get the trophy.
Any of the "optional photo" trophies can be easily obtained after finishing the episode by using chapter select and playing again in photo mode.
