yes, I'm not really being critical- they are quite lifelike though I think maybe its the colour that seems a bit out of place- even if its accurate for the Pampas- here grey might have been better, but I'm sure they will tone down.
When the weather gets warmer the keepers on this section will being the process of getting the anteaters to use the paddock and mounds, until then it's highly unlikely that they'll be spotted outside much.
It may be interesting, I recently observed wild giant anteaters and how they really feed. It turned that anteaters don't dig into termite mounds. Don't believe pictures and some staged documentaries!
Anteaters dig into the dry earth around mounds. I guess there termite walkways are almost unprotected. They dig with one paw, often just a little, sometimes deeper, like a man reaching into the rabbit hole. And they do it very often - almost every minute they stop, scratch the earth, throw away a lump of compacted dirt or two, put nose in, go further.
If Chester or other zoo wished to perfectly replicate Giant Anteater behaviour, it could make a series of narrow, deep pits (maybe 2 feet deep and 8 inches wide), drop the food in, and fill them maybe with fist-sized stones or pieces of wood.
