However, a similar material, hydroxyapatite, has led to successful bone healing in a critical defect model in pigeons (Columba livid) (14) Other bone stimulatory materials reported for use in bone defects in birds are an autogenous bone graft taken from the carina, an allogenic demineralized bone matrix, a ratite cancellous bone xenograft, and bone morphogenetic protein-2.
Emus like their cousins the ostriches are slightly unfortunate birds in that their body structure doesn't have a 'keel' (ratis, in Latin, from where we get ratite) to support their wings when extended, thereby rendering them incapable of flying even if they wanted to.

"Kiwi Simile" is an unusual, humorous nature educational book that combines pungent, witty, graphic-like illustrations with fascinating factoids and details about the life and habits of the New Zealand kiwi, a threatened species which is described as a bird and an "honorary mammal." The kiwi is the smallest Ratite, a category of flightless bird species.
Biologists in the 1970s debated whether the kiwi and other flightless ratite birds arose when flightless common ancestors drifted apart by riding on landmasses that fragmented and separated.
A new study by the University of Adelaide's Australian Centre for Ancient DNA (ACAD), has solved a 150-year-old evolutionary mystery about the origins of the giant flightless "ratite" birds, such as the emu and ostrich, which are found across the southern continents.

This is technically correct, though as Caughley pointed out, there is no forest ratite to replace the moa, but there are other browsers such as deer (and possum) which would provide not the same browse, but a browse that would help maintain the forest in as near to its pristine condition as it is possible in the 21st.

Indeed, while Ratite is no doubt right to emphasize the philosophical contributions of these philosophical works, Abhinava sometimes speaks in a theological register in the TIN and IPVV, even though Utpala essentially avoids doing so in his IPK and IPV.
