Mound-bird is a term used to describe birds that build mounds or excavate burrows in the earth for their nests. The term is often associated with the Australian brush turkey, a large ground-dwelling bird that is a skilled mound-builder. However, there are several other birds that exhibit similar nesting behaviors and could also be referred to as mound-birds. These include the mallee fowl, the orange-footed scrubfowl, and the megapode. Other words that could be used as synonyms for mound-bird would be ground-nesting birds, earth-burrowing birds, or mound-builders. All of these terms describe birds that utilize the ground as a nesting site.
