Facebook's News Feed has received a seasonal greeting message for the first time. The social network added an animation to celebrate the first day of spring/fall. If you're in the northern hemisphere, you may see a message with birds and if you're in the southern hemisphere, the message has falling leaves.
These animations, which are somewhat reminiscent of Google's Doodles, are only shown on mobile devices.
An internal team at Facebook designed the animations. These notifications join other News Feed messages that are intended to get users to "express their feelings and connect with things that matter."
If you click the greeting, you'll be able to create your own seasonal post that reads "welcoming spring" and features the seasonal graphic.
