A useful app
This Lite edition seems to function well. I am an American with limited knowledge of Australian birds. This app only describes 59 birds. However, they are well described. There are a number of color illustrations of each species, male and female. There are also nest illustrations. Many species have vocalizations available. There are detailed range maps available, in color. There is also a substantial amount of text describing each species. There is also a search function which allows you to find a bird based on features, appearance, color, etc. The app also apparently allows you to specify your home range. All in all, a good app. Full app is rather pricey, but may be worth it.
