I watched this a few nights ago and it's still on my mind. Flying over mountainous dense forest with no hope of a safe landing while swerving to stop the birds from flying into the propeller was exciting. But what got me was them waking up at dawn and going to bed in the same room at night, every day for weeks, wearing a yellow jump suit (so that the chicks would bond/imprint with them as surrogate mothers). Attenborough even says, "the pay is awful" - they are basically volunteers.

This makes me think of the "Moral Equivalent of War" - I mean, in some ways we really are in a war for sanity - nothing else explains such level of motivation. Those women are literally living their lives to the full fighting for something they passionately believe in.
