Dear J-E Missy/Kalli,
My last blog post mentioned two of my favorite new animals that I’ve seen in Tasmania: the duck-billed platypus, and MacLeay’s Swallowtail. Both of those animals are native to both Tasmania and mainland Australia, meaning they evolved here over millions of years.
Nick was wondering “if you will see a koala bear.” Koalas do live in Australia, but only on the mainland. Since Tasmania is a smaller island to the south, and you have to either fly or take a boat and cross 150 miles of choppy water from mainland Australia, koalas would have to be champion swimmers to get here by themselves. People often “introduce” animals and plants to places far away where they can’t bring themselves. Sometimes those introduced species can become a problem, because they don’t stay in balance with the rest of the living things in the place that they are introduced to. Because of the problems it has had with introduced species, Australia is now very careful about what it lets people bring into the country, and to islands like Tasmania. When you fly here, there are specially trained sniffer dogs in the airport that check you and your luggage out to make sure you haven’t brought in any kind of fruits, vegetables, animals, or any products made from them that could be carrying pest species.
I don’t know if anyone has ever tried to introduce the koala bear to the wild in Tasmania, but there is another introduced animal whose name sounds kind of similar: the kookaburra. It is a big bird that is known for its incredibly loud “laugh.” Actually, to me it sounds more like a combination of all of the loud jungle noises you could possibly imagine. Kookaburras live in family groups, so there are often several of them whooping it up at once.
Laughing kookaburras are native to eastern mainland Australia, but people brought them to other parts of the country, where they are now considered a pest. They nest in holes where parrots and owls usually would, and will eat baby birds and other little animals that can’t hide well or escape from them. Watching them in the old gum trees is entertaining, but when they show up, other birds leave. Last week I was hiking through a rainforest where there should have been great habitat for birds, but the only bird I saw or heard for hours was a kookaburra.
So, to answer your question, I won’t see a koala in Tasmania unless I go to a zoo. But I have seen its cousin, the native wombat, which looks like a small bear and has a face similar to a koala’s. It moves faster than a koala, though, so I sneak and spy on it when it is looking for food at dusk.
What native and introduced animals do you think live in Maryland?
