Re: Alvarezsaurs, their snout,myrmecophages and woodpeckers

Well, I'm sorry to say this, but you are wrong. Ant-eating birds coexist with ant-eating mammals in many parts of the world; for example, flickers coexist with ant eaters in South America, many species of woodpecker coexist with pangolins in Southeast Asia, and the Australian treecreepers, some of which are ant specialists, coexist with the numbat in Australia.

Well I guess you get me wrong.I know these coexist in these regions but what I ment we only have small myrmecophagous birds in these regions.To me this seems like niche partitioning. Large myrmecophages are always mammals in these regions while the only really small myrmecophagous mammal is the neortropical dwarf anteater. By contrast ALL tropical myrmecophagous birds are small,while they grow,or used to grow into large respectable sizes in areas devoid of these large myrmecophagous mammals,were birds with this diet occupy the anteating niches for both small and large species.
