Spring has officially sprung in Vermont! The trees are budding and flowering, plants are beginning to emerge and some are blooming, seasonal bird species are returning, and the weather is warm. The signs and sights of spring were visible in Centennial Woods, a lot of bird songs could be heard, but very few birds were seen. I was able to see two robins, but only heard the other birds. I heard the song of an American Crow, a Northern Cardinal, an American Robin, a Black-Capped Chickadee, and a Wood Thrush. Grey squirrels were also very busy chasing each other around. Grass and ferns were beginning to grow and green up again. The stream through Centennial Woods was flowing. Spawn could be seen swimming and water striders dotted the surface. I believe the spawn that were seen in the stream were Brook Trout. Here is an image:

In addition to observing the signs of spring in Centennial Woods, I also observed how different species interact within Centennial Woods. Species interaction diagram:
