A red-tailed hawk was hunting. A few days before, we had taken pictures of a such a hawk with breakfast in her beak.
Today, she was in the branches on the far side of the greenbelt, barely visible through the trees. She surveyed her domain, waiting for any movement. After several minutes surveillance, she'd fly to another location and resume her watch. Any time the hawk took flight, the crows in the area all cawed excitedly, sending an alarm.
This happened several times as my husband and I watched the hawk move to various locations.
We continued on the boardwalk and on our return, the squirrels were back.
Obviously the hawk had succeeded. The crows were quiet and the blue jays were visible again.
Everything was back to normal. The queen of the food chain had breakfast.
