The double-crested cormorant, found only in North America, is an iridescent black waterbird superbly adapted to catch fish. It belongs to a family of birds vilified since biblical times and persecuted around the world. Thus it was perhaps to be expected that the first European settlers in North America quickly deemed the double-crested cormorant a competitor for fishing stock and undertook a relentless drive to destroy the birds. This enormously important book explores the roots of human-cormorant conflicts, dispels myths about the birds, and offers the first comprehensive assessment of the policies that have been developed to manage the double-crested cormorant in the twenty-first century. Conservation biologist Linda Wires provides a unique synthesis of the cultural, historical, scientific, and political elements of the cormorant’s story. She discusses the amazing late-twentieth-century population recovery, aided by protection policies and environment conservation, but also the subsequent U.S. federal policies under which hundreds of thousands of the birds have been killed. In a critique of the science, management, and ethics underlying the double-crested cormorant’s treatment today, Wires exposes “management” as a euphemism for persecution and shows that the current strategies of aggressive predator control are outdated and unsupported by science.

This is the story of the survival, recovery, astonishing success, and controversial status of the double-crested cormorant. After surviving near extinction driven by DDT and other contaminants from the 1940s through the early 1970s, the cormorant has made an unprecedented comeback from mere dozens to a population in the millions, bringing the bird again into direct conflict with humans. Hated for its colonial nesting behavior; the changes it brings to landscapes; and especially its competition with commercial and sports fishers, fisheries, and fish farmers throughout the Great Lakes and Mississippi Delta regions, the cormorant continues to be persecuted by various means, including the shotgun. In The Double-Crested Cormorant, Dennis Wild brings together the biological, social, legal, and international aspects of the cormorant's world to give a complete and balanced view of one of the Great Lakes' and perhaps North America's most misunderstood species. In addition to taking a detailed look at the complex natural history of the cormorant, the book explores the implications of congressional acts and international treaties, the workings and philosophies of state and federal wildlife agencies, the unrelenting efforts of aquaculture and fishing interests to "cull" cormorant numbers to "acceptable" levels, and the reactions and visions of conservation groups. Wild examines both popular preconceptions about cormorants (what kinds of fish they eat and how much) and the effectiveness of ongoing efforts to control the cormorant population. Finally, the book delves into the question of climate and terrain changes, their consequences for cormorants, the new territories to which the birds must adapt, and the conflicts this species is likely to face going forward.

Populations of Double-crested Cormorants have been increasing rapidly in many parts of the U.S. since the mid-1970s. This abundance has led to increased conflicts, both real and perceived, with various biological and socioeconomic resources, including recreational fisheries, other birds, vegetation, and hatchery and commercial aquaculture production. This document describes and evaluates six alternatives (including the proposed action) for the purposes of reducing conflicts associated with cormorants, enhancing the flexibility of natural resource agencies to deal with cormorant conflicts, and ensuring the long-term conservation of cormorant populations.

Populations of Double-crested Cormorants have been increasing rapidly in many parts of the U.S. since the mid-1970s. This abundance has led to increased conflicts, both real and perceived, with various biological and socioeconomic resources, including recreational fisheries, other birds, vegetation, and hatchery and commercial aquaculture production. This document describes and evaluates six alternatives (including the proposed action) for the purposes of reducing conflicts associated with cormorants, enhancing the flexibility of natural resource agencies to deal with cormorant conflicts, and ensuring the long-term conservation of cormorant populations. There are four chapters that make up the critical components of an Environmental Impact Statement. Chapter 1, Purpose and Need, describes the purpose of and need for the action. Chapter 2, Alternatives, describes the six management alternatives that we considered: (1) Continue current cormorant management practices (No Action); (2) implement only nonlethal management techniques; (3) expand current cormorant damage management practices; (4) establish a new depredation order to address public resource conflicts (PROPOSED ACTION); (5) reduce regional cormorant populations; and (6) establish frameworks for a cormorant hunting season. Chapter 3, Affected Environment, introduces the reader to the environmental categories upon which the analysis of alternatives in chapter 4 is based: cormorant populations, fish, other birds, vegetation, Federally-listed Threatened and Endangered species, water quality and human health, economic impacts, fish hatcheries and environmental justice, property losses, and existence and aesthetic values. Chapter 4, Environmental Consequences, analyzes the predicted impacts of each alternative on the environmental categories outlined in chapter 3 and in comparison to the No Action alternative. The environmental analysis presented in Chapter 4 indicates that the PROPOSED ACTION: will cause the estimated take of less than160,000 DCCOs, which is not predicted to have a significant negative impact on regional or continental DCCO populations; will cause localized disturbances to other birds but these can be minimized by taking preventive measures, leading to the action having beneficial effects overall; will help reduce localized fishery and vegetation impacts; will not adversely affect any Federally-listed species; is likely to help reduce localized water quality impacts; will help reduce depredation of aquaculture and hatchery stock; is not likely to significantly benefit recreational fishing economies or commercial fishing; may indirectly reduce property damages; and will have variable effects on existence and aesthetic values, depending on perspective.
