The favourable properties of natural soundscapes are changing, due to declining bird populations and their new geographic distribution. As a consequence, the trill of birds is changing and birdsongs at dawn are becoming quieter and less varied.

Mountain birds in decline in Europe

28 de January 2019Anna Ramon Revilla

CREAF and ICO (Catalan Ornithological Institute) researchers Sergi Herrando and Lluís Brotons have participated in a study that shows populations of birds described as “mountain specialists” to have fallen by 10% in a decade in Europe. The situation is even more alarming in the Pyrenees and elsewhere in the Iberian Peninsula, where mountain bird populations fell by 21%.


Birds and butterflies are key indicators for the measurement of biodiversity loss

11 de November 2015Anna Ramon Revilla

According to a study in which CREAF participated, the populations of birds or butterflies living in open habitats have been negatively affected by the loss of field and scrubland habitat. Conversely, species which live in forests have been favored. These variations were related with changes in the Catalonian (and Mediterranean) landscape over the last few decades.
