Good pictures, wonderful caption. So much of nature, I think, invites the metaphor of breathing. Cf. also Barry Lopez (in Arctic Dreams) on the shifting seasons of the Arctic, on “migrations as breath, as the land breathing. In spring a great inhalation of light and animals. The long-bated breath of summer. And an exhalation that propelled them all south in the fall.”
