I used the photo in Wayfair of these little stick-on birds as a guide as to how to display them together in bird groups.  They come as individual pieces, including some of the branches and twigs.  So you can be creative in how you set up the branches (or extend them), and which birds you want on which perches.  There are so many of them, I put them on our bedroom wall, in the kitchen, and in my bathroom (Girl Cave).  As a backyard-birder, I really enjoy having these little tweeters on the walls in my house.  Spouse likes 'em, too, and he hates anything "too cute". 

Pros: Easy peel 'n stick.
