Laura Erickson's For the Birds

This bird that spends much of its life on the forest floor has a song that reaches the heavens. Wood Thrushes are declining due to a variety of factors, from all the problems associated with forest fragmentation to acid rain, which dissolves calcium from the soil, making it less available for invertebrates, and ultimately leading to eggshell thinning in the Wood Thrushes that depend on those invertebrates for their own calcium supply. It took 40 years for Laura to add this one to her yard list, but that’s where she got her only recording!
