Boise police and the state Department of Fish and Game are investigating after several ducks and geese at Julia Davis park have been shot with blow darts.
Some ducks were shot in their heads and necks, one was shot in its wing.
Authorities say they were likely shot yesterday evening or early today.
The Idaho Fish and Game says they've heard that at least five of the birds had been shot but it's hard to get a tally because many of the animals can still fly.
Two injured Canada geese have been captured and are recovering from their injuries.
The other animals are still on the loose and suffering.
Anyone with information about the crime is asked to call Ada County dispatch at 208-377-6790.
