00:00 (hummingbird chirping)
00:03 The blue-throated hummingbird is native to these forests.
00:08 This spy version hovers just like the real thing.
00:13 In the heart of this grove,
00:16 half a billion monarch butterflies lie sleeping.
00:20 They have traveled from as far as Canada
00:27 to escape the cold northern winter.
00:30 How they return to this exact spot is a mystery.
00:36 Like the butterflies, hummingbirds feed on nectar,
00:41 so our spy isn't seen as a threat.
00:43 While resting, they cluster together
00:47 to conserve precious warmth.
00:49 But as winter ends, the sun warms their fragile wings.
00:55 (birds chirping)
00:58 Once they reach a critical 13 degrees Celsius,
01:03 they start to fly.
01:04 As the day warms, the forest comes to life.
01:14 Spy hummingbird won't harm these delicate butterflies.
01:24 (birds chirping)
01:26 Its moving parts are shielded to keep them safe.
01:29 Butterflies can even safely land on its wings.
01:33 It soon captures something quite extraordinary.
01:52 (gentle music)
01:54 What starts as a trickle soon becomes a stream.
02:03 Then grows into a cascade.
02:20 A spectacle that has rarely been filmed.
02:23 And our spy is harmlessly in the very heart of it.
02:47 Beauty also lies in the detail.
