Final answer:
The Zimbabwe bird is actually fashioned after the Bateleur eagle, an emblematic symbol of Zimbabwe, which is not listed among the provided options.
Step-by-step explanation:
The Zimbabwe bird is fashioned after the Bateleur eagle (Terathopius ecaudatus), which is not one of the options provided in the question. The odds are that this was an error in the provided options. The Bateleur is a medium-sized eagle with striking black, white, and chestnut plumage, known for the adults' short tails and vibrant facial colors. It is an emblematic part of the Zimbabwean culture and features prominently on the national flag, symbolizing the nation's history and identity. It is neither an ostrich, guinea fowl nor black-bellied bustard.
