"The fact that kiwis probably don't care about flying ruined it (for me). [...] Am I the only one who thinks this? I'm not missing the point[...]"
No, you _are_ missing the point. Or you are being too much of a quasi-Autistic realist to think a little metaphorically (even though it should be fairly obvious that the bird is being anthropomorphized).
And to frankqb: [SPOILER] The bird was painstakingly nailing trees to a cliffside so that it could -- for one brief, self-destructive time in its life -- live out its dream to be able to fly, or at least to have the illusory feeling of soaring over a forest. 5 years 7 months ago
Keep living your dreams. Or something like that.
It took me a while to see what that bird was doing. Creative animal I must say 5 years 4 months ago
