Answer:
Wonder at the bear's beauty, its solitude, its clumsy attempts to feed itself on human rubbish.
Explanation:
In "Shadow of the Pines", the character of Mr. Hernandez is in a safe spot observing a "she-bear". And unbeknownst to the bear, he had been observing her go through the 'prize',<em> "[nosing] around in the pine needles for abandoned remnants of long-forgotten picnic lunches."
</em>
But the sentence that best demonstrates how captivated Mr. Hernandez was by the bear is the way he describes her. He <em>"wonder[ed] at the bear's beauty, its solitude, its clumsy attempts to feed itself on human rubbish."</em> This shows his fascination with the female bear, his interest in the wild animal's behavior.
