On the lookout for danger: House Sparrow alert distance in three cities

The House Sparrow Passer domesticus, closely associated with human presence along urban–agricultural landscapes and widely distributed outside its native range, has shown great morphological and physiological variations, with its plasticity linked to its invasiveness. Yet, there is a dearth of knowl...
