The fearsome hunting skills of a wild rattlesnake have been caught on camera for the first time.
Using a specially designed camera trap, a BBC crew managed to film the snake killing and then eating his victim - a small mouse - in the wild.
The mouse died almost immediately after being stabbed and injected with the timber rattlesnake's deadly venom.
The snake hunt was filmed in New York State, US, under the guidance of rattlesnake expert Harry Greene.
He helped the crew track the snake by using radio telemetry.
The footage forms part of the BBC One series Life in Cold Blood.
Life In Cold Blood is on BBC One on Monday, 25 February at 2100 GMT.
