Studies the benefits and costs of group living as illustrated by colonies of the gull-like seabird on salt marshes and sandy beaches of the east coast of North America. Examines such behavior as predator detection and defense, and competition for mates, nesting sites, and food. The observation of 30

This book is a result of the authors’ more than 40 years of study on the behavior, populations, and heavy metals in the colonial waterbirds nesting in Barnegat Bay and the nearby estuaries and bays in the Northeastern United States. From Boston Harbor to the Chesapeake, based on longitudinal studies of colonial waterbirds, it provides a clear picture of the toxic trends and effects of heavy metals in the aquatic environment. The authors take a food web, ecosystem approach to contaminants, using population dynamics, habitat selection, and inputs to the bay to examine metal levels. They also look at the human dimension, discuss what metals in birds tell us about human exposure, and describe stakeholder involvement in these issues.The book covers numbers and dynamics, colony sites and locations, and prey contaminant levels, and compares them to other comparable coastal estuaries. It uses colonial waterbirds as the focal point for an ecosystem approach to metals that begins with prey fish and goes through invertebrates to humans. Additionally, it provides information based on long-term integrative studies the authors have done on metal levels and bird species and compares the findings with data from the Harbor Estuaries Program, other Northeast bays, the Great Lakes, and the Wadden Sea.

Join Joanna Burger and Michael Gochfeld as they guide readers to New Jersey’s most marvelous natural spectacles. From mating horseshoe crabs in the Delaware Bay to goldenclub and orchids at Web’s Mill Bog, the authors show us Garden State nature at its best.While New Jersey boasts far more than 25 nature spectacles, the authors have selected those that are the most dramatic, predictable, and characteristic of the state so readers can easily enjoy them over and over again. Being in the right place at the right time makes all the difference, so the guidebook is organized by season to ensure the best viewing.Each chapter begins with a photo and a brief description of the spectacle. A listing of key locations, directions, and the best time to visit follows. A prime habitat section provides a brief characterization of the appropriate surroundings to look for the plant or animal spectacle. The description provides ambiance, natural and life history information allowing readers to enjoy fully what they are observing. A final section lists an agency or organization where more information can be found.The book contains maps as well as a calendar of recommended events, including the Lambertville Shad Festival and the Barnegat Bay Duck Decoy Festival. The authors also list a number of other spectacles that while they didn’t make the top 25 list, but are well-worth checking out-including a tongue-in-cheek look at what may be New Jersey’s best-known wildlife, humans at the shopping mall.This book grows from the authors’ quarter century of exploring the state’s estuaries, bays, fields, and forests, observing and enjoying its natural habitats. They’ve written the perfect guidebook for everyone, whether you are ready to head off to the great outdoors or prefer to read about nature from the comfort of your armchair.
