Ornithocephalus, bird head, is the name of this orchid, and the flowers really resemble little birds with tiny heads and long beaks. Their size is only about 1/5" = 5 mm.
I turned this picture upside down. In fact, the iris-like foliage of this epiphytic plant is growing downwards and the flowers are non-resupinate. Edit
: resupination: the "lips" of the nearly all orchid flowers we find in garden centers or at exhibitions are at a 6 o'clock position. This is what we humans consider to be the "normal" way but in fact these flowers are rotated by an angle of 180° - they are resupinate! Originally, the lip is at the 12 o'clock position and moves to 6 o'clock during the development of the flower bud. Only for some species, the position of the lip remains unchanged.
