Little is known about how shifting small mammal populations in response to climate change will affect the bird species that they predate. This project is relying on historical sampling and 2014 field surveys and trapping to examine how red squirrel populations have shifted in the mountains of Vermont and New Hampshire and how birds may be affected by these shifts.
The results of this work allow agencies to target efforts towards at-risk target species and habitats. Preliminary results have shown that red squirrels have not shifted upslope, and songbird reproductive success is highly affected by red squirrel presence.
