Alvarezsaurs, their snout,myrmecophages and woodpeckers

["Brian Lauret" <zthemanvirus@hotmail.com>]

Hi y'all
There's something that always puzzles me.Maybe it's just me being silly but 
I wonder: Is it realistic to illustrate all of those myrmecophagous (except 
Rapator perhaps,it seems a bit to large for such a diet) alvarezsaurs with 
snouts just like typical theropods while all living myrmecophages (with the 
exception of aardwolf,sloth bear and marsupial anteater,wich seem to be 
pretty primitive in their specialisation anyway)have their jaws stuck for 
the greatest part in a sort of skin presumably to create a tube for the 
tongue.Surely alvarezsaurs have been around for a long time so they surely 
had the timeframe to evolve into specialised myrmecophages.
And regarding animals with these diets,i wish to mention I think woodpeckers 
are the avian equivalent of animals like pangolins and anteaters. It seems 
strange to me we only used to have those big-ass woodpeckers like the 
Ivorybill in regions without large myrmecophagous mammals (in such 
relatively ant-less regions flight might be a nessecary equipment for 
myrmecophages of this scale)and small woodpeckers in areas that do have 
those while the largest members of a particular birdclade are usually the 
tropical ones.Woodpeckers do have those extremely long tongues and 
such..........just a thought.
Correct me if I'm wrong.
