Cities threaten millions of years of bird evolution

31 de May 2017Anna Ramon Revilla

A study led by Daniel Sol, CISC researcher based at CREAF, shows that cities preserve 450 million years less evolutionary history compared to natural environments. Birds capable of surviving in highly urbanized environments have undergone recent evolution. The arrival of exotic species does not compensate for poor urban evolutionary diversity.

Singing in higher pitches is no guarantee of success for city birds

20 de November 2015Laia Núñez Casillas

An international study with participation of CREAF has concluded that singing in higher pitches is no guarantee of success for city birds. This was after observing city-dwelling birds in around 20 cities worldwide, Barcelona being one of them. The researchers compared around 400 species and analyzed whether these were more abundant in their natural habitat or in urban areas. What is certain is that species which sing at higher pitches are heard better against the low tones of the city, but there are other abilities which are more important when adapting to urban life, such as finding food and avoiding urban dangers.

100 birds in your city and you don’t see them

Parrots at public parks and gulls flying landfills. Those are examples of some birds that have found the ideal place to live in our cities. We are increasingly demanding to create urban infrastructures and offer better services to citizens, but we are indirectly creating a new ecosystem for urban birds.
