You've got to get obsessed and stay obsessed

have not read the books seen the film HBP. Cannot recall seeing a black bird in a cage but have seen a white and black bird in a cage on Wiki in an entry birds on the seventh floor but also have seen an empty cage in the Draco poster at Harry Potter Wall art. Will have to review film to see if black bird is visible in any cage...is he ? Will also have to see if bites appear to be in apple to have any leaning towards theories. Sniggering at shop where second cabinet is kept can be interperted in several ways. Will have to review part where black bird ? Flies ? from cabinet at Hogwarts....BUT if this is a black bird why would it appear then ? Would DM send it then leave before it returned or just leave it in the cabinet afterwards. Additional scenes in HBP do not show any birds. Believe DM felt remorse as he caused bird to die. the poster of Draco at Harry Potter Wall Art seems to show this. Would really like an explanation if both birds can be seen in a cage anywhere ? Some posts in other forums talk about black bird being seen being put into cabinet in film. Does this make sense ? thanks for any help
