This is a Common Brushtail Possum (Trichosurus vulpecula) in one of the palm trees in our front yard. I took this photo on the evening of 26 March 2011.
The Common Brushtail is a nocturnal marsupial native to Australia and the largest of all possums. These possums thrive in cities and have a love of fruit trees and vegetable gardens.
During the daytime, brushtail possums take shelter in dens which may be located in tree hollows, logs, dense undergrowth and even roof spaces of houses.
