The Darting Bird Quilt Block is a 9-patch block made up of squares and half square triangles. The overall design is asymetrical, and if you look at it going one way you see the bird, but if you look at it the other way, it looks more like a flower or a crown. Either way, it has a lovely effect when grouped together or when paired with other blocks.
Below is an illustration of four darting bird quilt blocks, with each block rotated 90 degrees.
