I am amazed at his keen observation skills.

The owl is a nocturnal bird, known for its sharp vision and quiet flight.

He was watching the flight of the airplane.

The bird is flying in the sky.

He didn't know that fact.

I saw a bird in the park.

He is really knowledgeable and always teaches us new information.

He found out the truth and was surprised.

His dynamic visual acuity as a baseball player is very excellent.
