Police were called after a goose smashed through a taxi window.
Nottinghamshire Police said they received a call about the bird flying into the vehicle in the Radford area, over the radio on Monday.
The force said the goose was taken to the vet and the taxi driver had to repair the damage to the car.
In a tweet, Radford Road Police said: "When a colleague asked if a call had been received about a goose flying into a taxi over the radio, we had to see it to believe it.
"Goose was taken to the vets & unfortunately the taxi had to repair the damage.
"We think he may be trying to find his way to #goosefair #randomjob."
The driver, Nayyar Tabasam, said he had just dropped off a passenger at the city's university when he heard a huge crash from behind.
He said: "I thought somebody had thrown something at the car for a start so I slowed down to see if I could see anyone around but there was no-one.
"I then stopped and took a look in the back, where the glass from the window was, and I saw this big bird in my car.
"Of course it was a shock at the time, I didn't see anything as the goose was coming from the side and it made a lot of noise.
"A friend and I made a call to the police, who advised us on taking the goose to the vets, and just after this a couple of officers passing by came over, helped and reassured us which was great."
