Hi Shubh,

Initially the bird's speed was less than the speed of the car.

After hitting the car, the bird falls on the bonnet of the car. Hence, we can say that the final speed of the bird becomes equal to that of the car.

However, the car is still travelling with the same speed. So, the bird undergoes larger change in speed than the car.

Hence, the bird suffers larger change in momentum than the car.
