Interesting/Little Known introduced populations

I just heard about Moose in New Zealand! @Chlidonias How much do you know about this?

I didn't read that article until just now, but after reading it I do agree they are not truly wild.

 

I don’t know. Maybe not free-ranging...but if they are not managed, feed and breed on their own, and live outside year round? As wild a population as lives in many protected areas in their natural range. Or as wild as many bison and wapiti populations in North America. I’d say that legally the animals are probably considered livestock, but otherwise they meet four of the five criteria (my own I admit) to be considered a wild animal.

They do note a mention in Lone Pine’s Field Guide to Mammals of California.

 

I guess the main question is will they continue to increase or at least hold stable. A good point regarding the bison, most of them are still monitored and managed to some degree.

 

On a different topic, for those familiar with the spread of Rosy-faced Lovebirds in the Phoenix AZ area, do you think they might manage to start spreading across the southwest? Looking at Ebird data they are pushing outwards from the suburbs to some extent, as well as some outlying records. They have been doing quite well overall.

I remember when I was a child I used to go with my friends to catch bettas in a dam near La Habana. For me, was normal to find bettas, years later I learn that bettas are from Asia. But in Cuba are very common in dams, ponds, lakes or slow rivers. I captured bettas in La Habana and Pinar del Rio, mostly red/brown variants but also green, blue and even albino.

The Cuban Grassquit was introduced in the Bahamas in the 1960s. According to the story that is widely spread in Cuba, a plane carrying hundreds of those birds (the destinations varies) was forced to land in the Bahamas due to an emergency. A lot of the birds died, but the rest were released and they settle and flourish till the present day.

 

Very interesting about the moose and brush tailed rock wallaby.

Do you know how any of New Zealand’s invasive species got there? For some species is is quite obvious why they’ve been introduced, such as deer and game bird for hunting purposes, but for other species it’s a lot less clear. I’d especially like to know the origins of the various Australian marsupials, tahr, chamois and hedgehogs.

 

If you’re interested in the history of New Zealand’s introduced species, I suggest you consult the book “Naturalized Mammals of the World” (Christopher Lever; 1985) which provides a considerable amount of detail about the introduction of non-native mammal species to New Zealand. This book provides the dates of the introductions, the person responsible for the introduction and the sources of the original animals (e.g. the Duke of Bedford donated three pairs of tahr from Woburn Abbey in 1904; Franz Josef, Emperor of Austria, donated eight chamois in 1907 etc).
