A flock of blue birds often flutters around in the branches as I walk near Deer Creek, the male's colors so intense, blue with rosy breasts, the females more subtle and equally beautiful. A little way down the road a male pileated woodpecker occasionally works a tree trunk, so dressy in his polished black with white trim and his fancy red hat. He's so much bigger than the blue birds. Simultaneously sharing the same sky space are bald eagles, down from the Susquehanna, feeding on fresh meat put out for them in the field.

Such a size range. Just like humans. And who is to say which is more valuable?
