North Shore residents say somebody is poisoning hungry sparrows and leaving them to die on roads and footpaths.
Browns Bay resident Kate Mitchell said she found about six birds "stumbling around on the ground" on Clyde Rd on Saturday evening.
"They looked like they had been poisoned, so I got a box and collected them all and took them to the SPCA."
She was told the birds had been given a drug that made them sleepy and once unconscious they froze to death overnight.
