For each species we have created a file containing the basic information presented in a simple and visual way for finding out more and localizing it. As well as the photograph and the song, codes have been added to indicate the habitat where the species is most commonly found, and the approximate degree of difficulty associated with finding it (low, average or high). A brief description of its status is also given and, if necessary, advice for finding it. Finally a map is added showing a selection of the best areas for observing it in the breeding period.

In some cases it is better to find the species in the winter or in areas bordering the province of Lleida; then the map appears blank and the appropriate suggestions are given in the text. Foreseeably, (and more so in the case of birds due to their mobility) the status, distribution and the populations described here will vary in some cases, and that is why we will be very grateful to receive your contributions.
