A Little Penguin chick, more commonly referred to as a Fairy Penguin chick, has its head measured by a National Parks and Wildlife Service ranger near its man-made hutch on the foreshore of Sydney Harbour October 25, 2001. The National Parks and Wildlife Service is conducting studies on 70 breeding pairs of endangered penguins in what is believed to be the world's only colony in a major city. The decline in their once-extensive population is thought to have been caused by habitat destruction as urban development encroaches and predatory attacks by cats and dogs.
