Work on House Sparrows
Our work on House Sparrows has, in addition to data collected through the BTO House Sparrow Survey, involved examination of data collected through both BTO Garden BirdWatch and the Garden Bird Feeding Survey. This work is ongoing, underlining that there is still more to learn about the reasons behind the decline in House Sparrow populations.
