The teacher, from Detroit, spotted the squirrels Thursday as she ushered her students through a campus tour, The Ann Arbor News reported Friday. She noticed the young squirrels were not in their nest and a crow was eyeing one that appeared to have been left behind.
The teacher, whose name was not reported, first tried to shoo the crow away from the squirrels and then to draw the mother's attention to the danger. The mother squirrel instead turned on the teacher.
Diane Brown, a spokeswoman for the Detroit Public Schools, said the teacher fell while running back to the bus to get away from the angry squirrel. The animal bit or scratched her ankle, but the teacher was able to get up and escape.
