Here are some monotremes

A few days ago I posted an essay about my summer travels to conferences, linked by my incessant search for otters. Included in the post was a truly terrible picture of a platypus. The photo was taken from a platypus viewing hide in Yungaburra, Queensland, about an hour outside of Cairns. We sat patiently for quite a while at dusk, waiting for the platypus to show. By the time it did, the sun was so low there was not enough light to take a decent picture.

Platypus aren't just easy to see in Yungaburra. Canberra, where I live, happens to be one of the easiest places to see platypus in Australia. At the Tidbinbilla Nature Sanctuary there is a boardwalk over a wetland where wild platypus are active during the day. With a little patience and, ideally, some binoculars, platypus can be viewed well at anytime. I thought I'd post some better pictures of platypus taken at Tidbinbilla to offset the terrible one I posted last week. I am not, however, a professional photographer, and professionals could get much better photos than these!

Platypus are monotremes, the last mammals on Earth that lay eggs. The only other monotremes still around are the echidnas, of which there are four species. Three are critically endangered animals that only live on the island of New Guinea, and the fourth is the reasonably common short-beaked echidna, which lives on both New Guinea and Australia. Canberra is also a great place to see echidnas, though they are by no means as easy to see as the platypus. Some of the best places to see them around Canberra are Black Mountain and Mulligan's Flat.

The Australian National University, where I work, is the only university in the world (as far as I know) that is home to both platypus and echidna, which is pretty special.
