The "red list" of Stephen Cushman's new volume of poetry is the endangered species register, and the book begins and ends with the bald eagle, a bird that bounded back from the verge of extinction. The volume marks the inevitability of such changes, from danger to safety, from certainty to uncertainty, from joy to sadness and back again. In a single poem that advances through wordplay and association, Cushman meditates on subjects as vast as the earth's fragile ecosystem and as small as the poet's own deflated fantasy of self-importance: "There aren't any jobs for more Jeremiahs."Simultaneously teasing the present and eulogizing what has been lost, Cushman speaks like a Shakespearean jester, freely and foolishly, but with penetrating insight.
