Read this excerpt from a blog. I recently visited the city council’s web page and was startled to discover that the council members are making plans to build a new sports park at Bass Lake. We must do whatever we can to stop this from happening. This area is a popular nesting ground for the Lucy’s warbler, a threatened bird species. Removing trees and changing the landscape of this area will destroy the warblers’ habitat. For more information about the threats facing these rare and lovely birds, visit http://www. lucyswarbler. wiki.
