I was very fortunate to observe a flock of Swift Parrots on their short term stay at Mt Annan Botanic Gardens last year. In summer they move to Tasmania to breed.
These beautiful birds are critically endangered. One of the reasons is that their nesting habitat in Tasmania is being destroyed. There are large areas of national parks in Tasmania, but these birds move around depending on food sources. And quite often the best food is that provided by flowering Eucalypts in logging areas.
Some people care for the future of these unique birds. One person who does is Bob Brown. He has recently been arrested twice for protesting about their habitat loss. The real crime is that the habitat of the birds is being destroyed.
