Mayastra

Meiastre ( rum. Pasărea Măiastră , the magic bird) is a character of Romanian folklore , a fabulous bird helping Fat Frumos in his battles and trials.

In one cycle of fairy tales, Mayastra manages to steal three golden apples , which the magic apple tree gives once a year. Only the royal son can injure and catch her. In some cases, wounded or captured, the magic bird takes its real form - turns into a fairy .
