Cockies falling dead from the trees

From Martine Maron (Applied ecologist @ The University of Queensland. Deputy director, Threatened Species Recovery Hub. Conservation policy, biodiversity offsets, woodland birds):

48.9 degrees C on the farm (western Vic) yesterday. Cockies falling dead from the trees. People and wildlife cannot withstand the extremes we are already experiencing and this is just 1 degree of warming. We are on track for more than 4. 

The sulphur-crested cockatoo is an iconic Ozzie bird, found across Australia, and well adapted to the Australian climate and its hot summers.  If cockies are dying from the heat, things are grim indeed.
