There must be something more than habitat loss or pesticides.
Outside of Central Asia sparrows are introduced species, adapted to live on remains of our towns. Urban environments is the natural habitat of sparrows, like rats with wings. They don't belong to the wilderness. If sparrows are also disappearing then the loss of natural habitat is not the only answer.
Edit: from this graph [0] it seems that the loss is concentrated on introduced species (such as sparrows), shorebirds and insectivores.

- filboidstudge 7y agoIt sounds like you are referring specifically to the House Sparrow (Passer domesticus) which is not native to North America and is indeed strongly associated with urban environments.[0] But the native New World sparrows to which the article refers are a separate group of species and are dependent on natural habitat.[1] [0] https://en.wikipedia.org/wiki/House_sparrows https://en.wikipedia.org/wiki/House_sparrows [1] https://en.wikipedia.org/wiki/American_sparrow https://en.wikipedia.org/wiki/American_sparrow
