Move in and out of the attic containers until the crow appears at the window, then click it.
Official in-game clue: "Many things are staring from the window! Click on that bird!"
Where: Day 1 Night, in the attic, during Searching the Attic.
Why it gets missed
The clue tells you to click a bird that is not there yet.
Arrive in the attic, look at the window, and there is no crow. Most players conclude the achievement belongs to a later visit, or that they have already missed it. Neither is true — the crow is summoned by activity in the room, and the clue simply does not mention that step.
What to do
- In the attic, open and close the containers — go in, come out, repeat.
- Watch the window between moves.
- When the crow appears, click it.
There is no counter and no hint that it is working, which is the same design as petting the horse at the other end of the day.
While you are in the attic
The chest here takes the stars 4 2 3, left to right, and that combination is asked for again during the post-credits secret — write it down. Details on the attic chest page.
One more for this block: Checking for Intruders is not in the attic at all. Go back to the corridor window where you served the tea.
