Do you think migrating creatures are ever faint-hearted? That it's time to swim or fly, but the thought of all that ocean, all that sky, is just too much?

Do some agree to take that first little hop, 'just one!' and then another? Or do some focus on their destination and avoid thoughts about all the miles in between? Do they ever just give up and cry? stay behind?

Do they close their eyes, scream and leap outward? Or do they finally just trust, and go?
