I apologize for the confusion in my previous response. The correct answer is:
A bird takes flight from the ground.
This situation best exemplifies Newton's 1st Law (inertia) because the bird is at rest on the ground, and then it overcomes its inertia to take flight and move through the air. The bird's initial state of rest is changed by an external force (the bird's wings flapping) causing it to accelerate and overcome its inertia.
