Nature Sightings | Sudbury Valley Trustees

Our Nature Sightings images depict the many species of wildlife that make their homes in the SVT region.

SVT protects and cares for some of this region’s most important forests, wetlands, and grasslands—natural areas that provide homes to the wildlife we see on walks, in our back yards, and in fleeting glimpses on roadsides.

SVT is grateful to the many members and friends who share their photographs and videos with our Nature Sightings page for everyone to enjoy.

We also post selected images to our Facebook and Instagram pages, and we send a monthly Nature Sightings e-newsletter to interested subscribers.

Each year, we collect some of our favorite images into an online photo album:

Best of 2025 Best of 2024 Best of 2023 Best of 2022 Best of 2021 Best of 2020
