Carnaby's Cockatoo suffers 37 per cent population decline in one year

Flocks of Carnaby's Black Cockatoo are iconic sights for the people of Perth, the Swan River Region and the forests of the South west. But comparing two population surveys in 2010 and 2011 showed a 37 percent decline in numbers across the Swan river region. That is a 37 per cent decline in one year.

According to Statistical modelling based on the 2011 Great Cocky Count the population of Carnaby’s cockatoos (Calyptorhynchus latirostris) in the Swan Region was between 5200 and 8600 birds. A year earlier it was estimated that the population was 8000 to 10,000.

Wandering Albatross Riding the winds of climate change

We are stacking the climate dice against the survival of many species on planet earth. A few species may be able to ride the changes, at least temporarily. And so it is with the largest of birds, the wandering albatross, with some populations of this species able to take advantage, so far, of the changing winds of climate change. But for how long?

Global warming has caused the westerly winds in the Southern Ocean to increase in intensity and move poleward. The wandering albatross, with a three metre wing span, spends much of it's life soaring above the ocean searching for food, with the changes in the winds increasing it's foraging ability, breeding capacity and reducing it's conflict with commercial long line fishing operations.
