The pink bird's name in Angry Birds is "Stella".
the original angry bird
In angry birds, the birds' names are never revealed. Most people just call them by the color of them. For example, the black bomb bird is called "Black Bird." The yellow bird that speeds up is called "Yellow Bird." Therefore, I doubt one of the birds would be called filcker.
There are actually three blue birds in the original Angry Birds as well as in Angry Birds Space. They are simply referred to as Blue Birds. Alias' for these birds include The Blues, Glassjaw Birds and Cluster Birds. In Angry Birds Rio, Blu and Jewel are both blue in coloration although they are Blue Macaws.
