No, a rabbit could not have eaten a bird. If a rabbit is extremely aggressive (due to anxiety, insecurity), it is perhaps possible that a rabbit might attack a bird: but there's absolutely no chance a rabbit would or could eat a bird.
Take it to someone who would know such as a veterinarian or a pet store that deals with birds.
Me, Maro, would like a cat, rabbit, a bird, a puppy, or any animal that doesn't need me to clean it's poo and has fur. An animal(s) that you can take care of properly and wanted to have for a long period of time. I would Love a cat, bunny, bird, or a fish... I don't really like dogs as pets for myself. I love dogs, but I don't want one. To much work.....

your rabbit may have an open wound you are un aware of, take them to the vet and tell them about this probelm.
The easiest bird to take care of is a parrot. All they do is eat and speak.
