Head in the sand…not quite. Ostriches have been observed swallowing sand and small stones, possibly to aid digestion.
I seem to remember that the whole “head in the sand” thing started out as “head in a bush” with someone philosophising that ostriches did the whole “I can’t see you so you can’t see me” thing.
There’s nothing quite like humans’ assumption about animal behaviour.
Today, with yet again no new requests, I aim to fly in the face of knowledge and learning by giving you an ostrich with its head in the sand…
