Take a look at this awesome remote controlled eagle. This thing is huge -- over 9 feet, actually. In addition to soaring, the eagle can also fly in loops and hover in place against the wind. This has to be the most impressive bird-like flying toy I've seen so far.
From the RC eagle description:
This is the remote controlled bald eagle with a 9 1/2' wingspan that catches the wind for broad, soaring turns. It is powered by a gimbal-mounted engine and propeller that provides nimble, multi-directional vector movement which replicates the bird of prey's agile turns and dives. The natural curvature of the nylon/polyester wings creates an airfoil that provides lift for the carbon fiber frame and wing struts. The transmitter controls the eagle up to 500' away; trim controls allow fine adjustment to left, right, up, and down thrust of the propeller.
