Morphology
The meaning is fully compositional: 'ratite' denotes large, flightless birds and 'bird' denotes a feathered animal, so 'ratite bird' simply refers to a bird that is a ratite. Although somewhat redundant and technical (since 'ratite' already implies 'bird'), the overall sense is directly derivable from the constituent meanings, making it transparent to learners who know both words.
Etymology
Ratite bird gets its name from a word meaning 'raft' because these birds have a very flat breastbone that looks like a little raft instead of the high ridge used for flight. So, the name helps explain why ratite birds 'cannot fly' and are large, flightless birds.
