The yellow bird, a well balanced piece that spins, like a weather vane, in any breath of air, is really a letter opener, designed by Yohei Oki. It joins the micro-lego cockatiel, a green porcelain parrot, plastic barn owls, Rosellas and lorrikeets,  a pair of pottery budgeerigars, a mirror generic bird, a finely constructed black net sparrow and a Lalique dove.  It must be the shape, the two clean lines that meet at beak and tail tip - perhaps a reminder of of the egg, that makes small scale birdables so appealing.  At least that's my excuse.
