The Shining Swan - P. K. Butler - Bog

In Ireland, where her great-grandmother owns a castle, Claire learns that she is the descendant of a magical race that once ruled ancient Éire. And like her ancestor Gealala, a 13th-century ruler known as the Shining Swan, Claire possesses an ability to summon birds. In fact, four raptors come unbidden to assist her in fulfilling a hereditary destiny to protect endangered waders. Irish curlews, nearly extinct, have chosen to nest on the shores of Lough Gur, the Enchanted Lake. To save their threatened habitat, Claire relies on a host of friends, including a neighbor's eight-year-old foster child and expert fairy hunter. Together they decipher long-hidden clues to revive the mystical power of a mythical past.
