Angry Birds won't be making its way to Facebook anytime soon, a new report claims.

According to The Next Web, which says it spoke with Rovio's Peter Vesterbecka, the wildly popular game won't be available on Facebook until May, two months after it was expected to launch on the social network.

Last week, Rovio announced that Angry Birds would be coming to Facebook and said it would launch in March. Vesterbecka reportedly told The Next Web that he was "not sure how the March date got in there."

Rovio did not immediately respond to request for confirmation of the May launch.

Rovio's hit game has been an unbridled success in the mobile space. The title is available to iOS-based devices, Android-based products, and the Nokia N900. It's also available in Apple's Mac App Store. Since its launch, the game has performed extremely well on all the platforms it has been made available on. It's currently the top paid app for the iPad and the second most popular paid app on the iPhone. It holds the second spot in the Mac App Store.

But when it's made available to Facebook users, Angry Birds will be facing off with several popular competitors.

In January, CityVille catapulted to the top of Facebook, hitting 100 million active users in just over a month after its release. The title is flanked by several other popular titles, including CityVille predecessor FarmVille, which currently has nearly 50 million active users on the social network.

It should be rather interesting to see if Rovio's Angry Birds will be able to overcome those competitors as easily as it has vanquished others in the mobile space.
