Is it possible that Dromornis feed almost exclusively on the nestlings of colony nesting birds, for example pelicans during some periods of the year and on ratites like the emu during dry seasons? Their hoof like feet would come in to good use only in hot sand and coarse grass/brush but would limit their locomotion in muddy marshes but not seasonally flooded grasslands. The massive bill and head structures may also have had a function in the dispatching of monitor lizards and snakes. The shield like bills of the gallinules and hornbills come to mind. Gallinules forage on animals as do hornbills. Ground Hornbills may be similar in some ecological aspects with Dromornis. But the size of the body suggests to me that during the wet seasons the species lived as a semi aquatic species. Perhaps its chicks were reared in flooded grasslands much in the same manner as Rheas.
Question: Is it certain the Dromornis was the largest? The largest variety of Moa was up to 3m, so maybe some sort of comparison would be good? JD
who was the first to know about these animals? —Preceding unsigned comment added by 69.137.7.0 ( talk) 23:31, 18 February 2010 (UTC)
Fossilworks and some papers refers Bullockornis as Dromornis planei. I wonder whether the page should be merged?
Per the discussion above, and as noted by @ FunkMonk: on the individual species pages, the three stand along articles Bullockornis, Dromornis stirtoni and Dromornis australis, should be rolled into this article per WP:Paleo guidelines, and to avoid information redundancies.
Hi there, I do not specialize in researching prehistoric birds, but I do research a lot on Cenezoic mammals in general (only majorly edited for Enhydriodon but I plan on expanding a lot of Cenezoic mammal pages in general in the near-far future), so I feel like I can chime in regarding a recent edit war on the extinction subsection from @ 103.49.5.53, Materialscientist, and Roundish: (I don't know how to properly tag an anonymous IP). I can definitely understand the intent behind the reversions of the anonymous IP, but I think the IP user has a point since Dromornis did not exist by the Pliocene let alone the Pleistocene unlike Genyornis. As cited by one source linked at the end of this sentence, Dromornis only existed during the late Miocene, the difference between it and Genyornis of the Pleistocene being that "D. stirtoni lived life in the slow lane, that is, it did not experience any selection pressure to grow quickly, something it shared with most large birds that lived on islands. As such, it took several years to reach adult body size and took only a few more years for skeletal maturation. This contrasts with G. newtoni, that lived in what may have been turbulent, stochastic times with unpredictability in terms of rainfall, available browse-forage, and so forth (e.g., Martin, 2006; McInerney et al., 2022), and these birds may have been under strong selection pressure to grow more rapidly to adult body size, after which skeletal maturity could occur more at a more leisurely pace (hence several more LAGs in the OCL)." [1] It therefore does not make any sense to blame humans for the extinction of Dromornis because humans arrived during the late Pleistocene while Dromornis already went extinct before the Pliocene as opposed to Genyornis. Dromornis and Genyornis lived in two different time periods with different environments and competition. PrimalMustelid ( talk) 18:15, 7 January 2023 (UTC)
