Avefy allows you to learn and practice the skill in identifying birds by the sounds they make.

From a wide possibility of different environments in pine forests, holm oaks, cities, thickets and many more, it is practiced playing with the birds that can be found in each one of them.

There are four levels of difficulty that are differentiated by the number of bird species to be identified and their overlapping singing activity over time. The successes and failures score differently also in each level. It can be practiced individually or compete with other players.

For all the bird species that appear, a card is available with their image and information about their distribution in Spain and population trends, as well as the description of their song.

The names of the birds are available in Spanish, Catalan, Galician, English, Portuguese and Latin.

Each game lasts 5 minutes, in that period there will be a list of different species every 20 seconds that will change if they are identified. Those that are not identified after 20 seconds are considered failures.
