The Cooper's Hawk presents the general reader and professional biologists interested in birds and nature, with an authoritative account of the breeding biology of the what is perhaps the most abundant, backyard breeding raptor in North America. This urban status exists despite cross-generational human persecution through shooting of individuals and indirect felling of forests, their apparent preferred nesting habitat. Using conversational prose, the natural history of the bird's diet, including bird feeder use and disease concerns, courtship behavior, and the ecological themes of breeding density, reproductive success, and adult survivorship are described. There too is a focus on how and why fieldwork is conducted on this ubiquitous city dweller who preys mostly on birds, or 'urban fast food.' How urban birds may differ from their rural counterparts is addressed, and especially highlighted is the novel aspect of reproductive deceit in this red-eyed, blue-backed predator, as, unlike all other birds of prey studied to date, it is highly promiscuous. The text is complemented with original art and especially crisp photographs that demonstrate this bird's natural history.

Описание: What usually struck people about Joe Rosenfield was his wit and unwavering love for Grinnell College. In fact, Rosenfield once said about the college: "After about my third week in the place I'd fallen in love with it. A team of horses couldn't have dragged me away." His passion for the college and its success shined in his dedication to the Grinnell Board of Trustees, where he served from 1941 until his death in 2008. Rosenfield's favorite sport, even counting his 5 percent stake in the Chicago Cubs, was making money for Grinnell. His own out-of-the-box thinking and close friendship with famous investor Warren Buffett helped grow Grinnell College's endowment from $78,000 at the beginning of Rosenfield's board service to just over $1 billion more than a half-century later. "Mentor" will take you on a journey through Rosenfield's life, from his days as a Grinnell student in the early 1920s to serving as the chairman at Younkers to becoming an instrumental figure in Grinnell College history. The stories inside display Rosenfield's steadfast desire to make a positive impact, one of the many reasons he was beloved by so many.- KAY BUCKSBAUM George Drake first came to Grinnell as an undergraduate in the class of 1956.
