hello everyone,

an interesting paper was just published today in PNAS. this study reports
that following the traditional birdfeeding practices (bits of bread and a
handful of seed) in urban areas does affect populations of wild birds in
cities by favouring introduced species (which are either omnivores or
granivores) over native species (which are more specialised in their food
preferences):

hopefully, this study will be the first of many that investigate the
ecological effects of birdfeeding!
