Three baby parrots were stolen during a burglary in Middleton.
The four-week-old Green Neck Parrots were snatched during a break-in the early hours of Sunday morning, and may die if they are not found.
Police have launched an investigation into their disappearance.
The chicks were being hand reared by their owner after being rejected by their mother.
Police say the tiny birds require hand feeding every two hours to stay alive.
Greater Manchester Police have shared a picture of the chicks and are appealing for anyone with information to contact the force.
"Unknown offenders have stolen three Green Neck Parrots which are four weeks and have been rejected by their mother so the victim was hand rearing them.
