Celebrating 10 Years of Nature’s Notebook
This month we celebrate one of our long-time observers. Cathie Bird has been submitting observations to Nature’s Notebook for all 10 years of the program! At her home in Tennessee, she tracks the phenology of Northern Cardinal, Black-capped Chickadee, and more! Cathie has created a rich, long-term dataset that can show changes in phenology over time.
