Steam Community guide by Munty.

Overview

In this guide I will show you where to find all the Sparrows I've found in the game.
So far I've found 19 out of the 20 Sparrows.
The 20th sparrow was found by Socks in the comments. Thanks Socks!

Sparrow #4

Note: This is above ball pit #6. I suspect you need to fill up the ball pit in order to catch the sparrow.

Hotel

In the Hotel the room move around.
As noted in the comments, which rooms the Sparrows appear in seems to be random for each playthrough. Once you have checked a room for a sparrow however, you can click on the rooms number plate and that will add a red strikethrough to the number. The number plates will always stay with the same rooms no matter where in the hotel the room has been moved to.
