One person who was attacked by the crows was Mr Cheng Kok Siong, who was walking from shopping mall Junction 8 to his home in Toa Payoh North along the path.
A crow was seen diving down from a tree branch above Mr Cheng and pecking at his black jockey cap.
“I was walking back home from Bishan Junction 8 to Toa Payoh, suddenly I felt a bird attacking me,” Mr Cheng told CNA.
“I continued walking since the bird didn’t continue attacking me,” he added.
Mr Cheng said that he normally walks down the same path between 3pm and 4pm, and that this was the first time he had been attacked.
“My concern is once in a while my kid would cycle this way or walk this way. Next time I would not walk this path,” he said.
He added that he might take the path which goes past Guangyang Primary School instead along Bishan Street 12.
CNA has contacted NParks and the Bishan-Toa Payoh Town Council for more information.
