The current app version contains the descriptions and images of all 700+ bird species found in Paraguay. Moreover, an ornithological dictionary (English, French, Spanish, Portuguese) and illustrations of bird anatomy are included.
Apart from using the optional backup and restore functions for Field Notes and Favorites, the app runs completely offline and there is no need for an internet connection during usage in the field.
As with "The Birds of South America", which contains more than 3,000 birds found on the entire continent, also "The Birds of Paraguay" runs on any iOS device and can exchange Field Notes and Favorites lists between identical versions on two or more devices via Bluetooth.
