A free program for Android, by iim mobile.
This free application for smartphones has a beautiful collection of bird wallpapers. They are designed to be the most attractive, and at the same time, the most interesting. The user interface is so simple that even the younger ones can easily navigate through the application.
The collection of wallpapers includes a large variety of birds such as parrots, eagles, owls, hummingbirds, hawks, swans, and many more. All of them are in full HD quality, and they look even better than the pictures of real birds.
The best thing about this application is that it is completely free. The developers are so dedicated to creating free applications that they are willing to put in the time and effort to make this one the best.
