I watched the ospreys hunting over the lake behind the house. One by one, they would stalk the defenseless fish swimming too close to the surface and then dive into the lake when they'd selected their victim. Not a moment later, they'd break through the surface with a poor fish flailing and fighting for its life, only to carry it away and bring it to its final demise.

Which words reveal how the author feels about the birds?

Dive, break
Stalk, defenseless
Lake, house
Lake, swimming
