Store description excerpt

Professional Field Guide (Bird Identifier) for 680 bird species inhabiting Russia - from Eastern Europe to the Russian Far East, and from the Arctic Ocean to the Central Asia. The list of bird species included in the app can be viewed at https://ecosystema.ru/eng/apps/20birds_ru.htm BIRDS IDENTIFIER The application has a built-in polytomic Bird Identifier (filter), which helps to determine the unknown bird by 24 different features. To do this, select the geographical region, the size of the bird, plumage coloration, streaks, beak and feet shape and color, distinctive features of appearance, behavior, habitats, location of a sitting bird, song and calls, daily activity, nest size, shape, construction material and location, eggs size and color. The Identifier will help you to narrow down the range of species for unknown bird. PHOTOS AND DESCRIPTIONS For each of 680 species, a photo of the bird in nature is provided (the image can be enlarged), as well as a text description of its appearance, behavior, features of reproduction and nutrition, distribution and migration. BIRDS CALLS For each of 680 bird species, the app provides one combined recording, including male songs and several most typical calls – alarm, aggression, interaction, contact and flight calls, etc. Each of the recordings can be played in four different ways: 1) once, 2) in a loop without interval, 3) in a loop with an interval of 10 seconds, 4) in a loop with an interval of 20 seconds. QUIZ The app has a built-in Quiz, which can train you to recognize birds by their voices and appearance. You can play the quiz repeatedly – the questions for recognizing species alternate in random order and are never repeated! The difficulty of the Quiz can be adjusted – change the number of questions, change the number of answers to choose from, turn on and off bird images. IN-APP PURCHASES The main features of the app are free - for each bird species, you can view its image and text description and add species to Favorites (these features are available offline), as well as to play the recording of its voice (if you have an Internet connection and no more than 1 time per minute).
