Prosecutors in America are trying to work out whether they can use a parrot as a witness in a murder case after it apparently described the last words of the victim.

Glenna Duram, 48, is charged with the murder of her husband, Martin, in front of the couple's pet African grey parrot at their home in Michigan in 2015.

His relatives believe Bud overheard the couple arguing and has been parroting back their final words, switching between a male and female voice.
