Mini Activity- Snag Watch: Dead snags are one of the most important components of a resident bird’s winter habitat. As you commence your bird walk, list or map each dead tree (a.k.a. snag) you pass, keeping an eye out for cavities (i.e., holes). Over the course of your walk, ruminate on the relationships between snag size and cavity size. You may find a correlation between the abundance of snags/cavities and bird abundance, especially at dusk. Use a stick to rap on some snags with prominent cavities and see what pops its head out to investigate (though don’t overdo it- be courteous to our winter wildlife). Why are snags important, and what species are most likely to utilize them?
During my bird walk, I was not able to locate any dead trees, therefor I didn't find any dead snags. There are only a few trees in my backyard, and within the trees that are around my house there is no dead trees. With snags that I have seen in the past, the bigger the snag, the bigger the cavity size. The bigger cavity sizes allows for more/bigger animals to make that cavity their home. Snags are important to wildlife because they give animals a natural shelter and nesting location. They also provide a food source for some animals. Usually squirrels, raccoons, and smaller mammals live in these cavities in dead snags. For bird species, woodpeckers, jays, doves, and song perching birds live in these cavities.
