The identification of the different swift species is not easy! It is particularly difficult to distinguish the most similar species such as the Common Swift, the Pallid Swift and the Plain Swift. The large number of poorly identified birds impoverishes the data collected, making it difficult to determine the distribution and phenology of these species, as well as establishing trends that allow an assessment of the status of their populations. Here you will find a summary of the information published in this article, which aims to contribute to the accuracy of the identification of swifts.
