During my little campaign trip I saw at least 20 echidnas! They were everywhere!  Prickly little bulldozers on determined missions to find termites.  They seem to be able to move through any obstacle.  If you get too close or make unexpected noise they double down, curl into an impenetrable ball and seem to be able to literally descend into the earth disappearing before your eyes.  If you sit silently at a reasonable distance they soon emerge and continue on their mission to find termites.  Very interesting to watch, quite fascinating.  I was very happy to see so many in a single day.  In the past I have rarely seen them and only in the desert not the forest.  It was a very gloomy overcast day with fine drizzle.  Difficult to photograph a dark creature that keeps his head down most of the time.  I found by lying on my stomach about twenty metres in front of an echidna on a mission I was able to be on eye level with them and capture the face and in a few images the eyes.  Here is a couple.  I like the first one which details his sandy little snoot, this must have been a good spot because he stopped and began digging and feeding.
