The Northern Territory is home to expansive and varying eco-systems from desert, savannah woodlands, and sandstone plateau to wetlands, mangrove and monsoon forests. It also welcomes unique weather patterns – a perfect combination that brings in over 400 bird species. Several bird species are native and unique to the NT, including the White-throated Grasswren, White-lined Honeyeater, Hooded Parrot, Chestnut-Quilled Rock Pigeon, Banded Fruit-Dove, Partridge Pigeon (Red-faced) and Helmeted Friarbird. A further 14 rare species, including the Gouldian Finch, can also be spotted throughout the territory.
