They're mostly solitary, elusive animals. With highly sensitive hearing and a good sense of smell they're easily able to avoid unwelcome company, even of their own kind. So the coming together of echidnas for breeing is quite a sight and a relatively rare chance for us to view echidnas in the wild.
Along with platypuses, echidnas are the only living members of an ancient order of mammals, the monotremes. Last century, echidnas caused an uproar among scientists when in a Scottish naturalist William H. Caldwell announced to the British Academy that monotremes lay eggs. At the time it was even proposed that humans evelved from reptiles.
She's one of very few people to have seen echidnas mating. Fact file: When: Echidnas breed in Winter. Where: Echidnas are Australia's most widely distributed mammal. Other info: Lovelorn male echidnas queue up behind a female, nose to tail, forming long trains. The most likely time to catch sight of them is around dusk or dawn when they're out foraging, although in southern Australia in winter they can also be out and about in the middle of the day. Echidnas don't like to get hot and, depending on where they are in Australia and the time of the year, they'll change from day active to night active.
One of the best signs that an echidna is about is the mark they make with their snout in soft sand and soil when they're searching for food, a small triangular furrow with a round hole at its apex.
Also they have distinctive cylindrical blunt ended scats faeces , about the size of human's small finger. Echidna trains can last anywhere up to 6 weeks before mating eventually happens. During this time the echidnas can be seen walking, foraging and just simply resting together. Echidna trains can have any number from two to 11 echidnas, though three to four is more usual. The males sometimes move from one train to another.
The males follow the female and sometimes make advances by nudging her tail or side with their nose. When the female signals that she's ready to mate another colourful display of the echidna's sexual behaviour begins the mating rut.
The female stops and often partially digs her front legs and head in near the base of a tree or bush. The male echidnas start digging a trench beside the female.
They then try to push each other aside, and end up digging around the bush as well as beside the female. The result is a doughnut-shaped rut which about centimetres deep. The rings have puzzled many a bushwalker. Eventually the males begin pushing each other head to head until only one remains in the trench with the female.
Mating finally begins, with the male having dug slightly under the female. He turns on his side and they mate cloaca to cloaca. If there is only one male, the mating ring becomes a simple straight trench. Men who kidnapped Piggie the echidna had hoped to find crocodiles. Read more.

Rough week? Echidna cam is here to help By Andy Jeffrey. Mortality and Health Survival rates Morrow and Nicol report that high mortality of young occurs during the period when mothers remain within their nursery burrows the first two weeks of lactation Cause of death unknown, but may be related to temperature conditions Rismiller and McKelvy report that, on Kangaroo Island, only 8 of 22 young that hatched survived to weaning The authors estimated that a female echidna may only produce one young every 4 to 6 years, despite an annual breeding cycle Other critical life periods may include the first few months after weaning and during dispersal Nicol and Andersen b Predators Augee et al.
Life in the Slow Lane "When we look at the details of echidna biology, we are not looking at a 'living fossil' that has failed to join modern mammals such as ourselves in the 'fast lane', but [rather, the echidna has] found a niche in the 'slow lane' that is so successful that it has remained there for millions of years.
