Jefferson County is home to an abundant variety of bird species. To celebrate and preserve these species and their habitats, we are excited to offer a Big Year in 2018. 

Join fellow community birders in identifying by sight or sound the largest number of species of birds within Jefferson County between January 1 through December 31, 2018.
