In The Birds of Bolivia all species of birds regularly found in Bolivia (>1,300) are described, and their approximate size given in inches and tenths of inches.

The range of each species is indicated, often in much detail. In addition to the birds‘ geographical ranges, the altitudinal zones which they inhabit are given. The zones and their limits are:

• Tropical Zone:
sea level to 4500–5000 ft
(1,400 to 1,500 m)

• Subtropical Zone:
4500–5000 to 7500–8500 ft
(1,400–1,500 m to 2,300–2,600 m)

• Temperate Zone:
7500–8500 to 9500–11,500 ft
(2,300–2,600 m to 2,900–3,500 m)

• Páramo or Puna Zone:
9500–11,500 ft to snow line
(2,900–3,500 m)

The current app version contains the descriptions and images of 1,375 bird species found in Bolivia. Moreover, an ornithological dictionary (English, French, Spanish, Portuguese) and detailed illustrations and drawings of bird anatomy are included.

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 Bolivia runs on Android devices and can exchange Field Notes and Favorites lists between identical app versions on devices of other users by exchanging export files.
