Free Birds Screen Saver is a collection of color photographs of rare varieties of birds. It displays the images as a slideshow, with periodic bird call sounds. Options let you choose the time delay between images (in seconds or minutes), select which transition effects to use, and stretch the images to fit the screen or display them in their original size. This screen saver also supports Microsoft Plus!. This lets you select "hot corners&quot\; on your screen to automatically display the screen saver, or prevent it from appearing.
