Little is known about the history or origins of the Space Eagle. The Space Eagle is Mighty Eagle when he entered the Space Wormhole. Space Eagle is summoned using Sardine Cans, just like the Mighty Eagle. When the sardines are launched, a space warp will appear and the Space Eagle will do some damage to the level. The player then continues to play the level as normal with the remaining birds. An Eagle Highscore still appears.
Unlike Mighty Eagle, there are no time restrictions on use, and you can use several per level. You can earn them through gameplay achievements, and he is available as an in-app purchase on iOS and Android via the Android Market (Google Play).
Tip: When you get 100% Total Destruction on all the levels of an episode, a feather will appear next to the episode's object. It was formerly three feathers with a glowing color, but it was replaced with this in recent updates.
If you look in the birds game sprites on Angry Birds Space's files for PC, you can see Space Eagle in the sprite sheet along with the other birds.
The Space Eagle somewhat resembles a raven or crow with it's purple plumage. It also has two plume feathers on top of his head. The Space Eagle's beak appears to be strongly curved, but that's to be expected. Space Eagle appears much larger than Earth-going Mighty Eagle but is much weaker
In the Beak Impact levels, Space Eagle is replaced by the Mighty Buzzard, that behaves the same way but it's dark blue, happy, old, with white hair and with a different beak in appearance.
