House Sparrow Project
Spring 2025
The House Sparrow Project has come to an end. We are now analysing the results and will share them with you soon.
House sparrow populations have declined by 69% in England since the 1970s and have been listed as a species of conservation concern. The drivers of this are still not fully understood but we want to change this.
The House Sparrow Project aims to establish where house sparrows occur in Essex and why this may be. This species is associated with human dwellings, so they are likely present in most neighbourhoods. However, we must gather data on areas where house sparrows are absent, too.
