Staff at the Norfolk Island National Park and Botanic Garden have photographed unusual behaviour by Norfolk Island Boobook Owls. As this image shows, the birds are hunting in broad daylight - something unheard of with the Southern Boobook, the species to which the Norfolk birds belongs.
The hunting by Boobooks of large rodents is also regarded as highly unusual, as the species feeds primarily on insects.
The population of the Norfolk Island Boobook had been reduced to just one female until she bred successfully with two male Boobooks introduced from New Zealand. National park manager Coral Rowston reports that the population is now about 40.
