Dr. David Mizrahi – Connecting the Dots: Understanding Dramatic Declines in a Widespread Migratory Shorebird
November 5, 2018
Dr. Mizrahi will review 20 years of research to unravel connectivity in Semipalmated Sandpipers populations throughout the annual cycle and determine what factors during the winter, migration and breeding periods underlie significant declines in populations, especially those migrating through the Western Atlantic region. He will also discuss conservation efforts that address several of the major stressors these populations are experiencing.
Dr. David Mizrahi earned his PhD in Zoology at Clemson University under the direction of Dr. Sidney Gauthreaux. His dissertation research focused on the ecology, physiology and behavior of Least and Semiplamated Sandpipers during spring migration staging periods in Delaware Bay. Since 1999 he has held the position of Vice-president for Research and Monitoring at New Jersey Audubon. Under his direction, the department has become a leader in the conservation of migratory birds. Many of the department's projects are regional in scope and in some cases, international. Research and Monitoring staff is currently working on projects to conserve young forest habitats used by conservation concern species like Golden-winged Warbler and Prairie Warbler, assess the status of Black Rail populations in New Jersey, restore habitats for beach nesting birds like Piping Plover and American Oystercatcher. Dr. Mizrahi's area of expertise is the ecology and conservation of shorebirds with a primary focus on Semipalmated Sandpipers and other shorebird species that winter in northern South America and migrate through the western Atlantic region. Since 1995, he has conducted important research on the ecology and behavior of shorebirds using soft-sediment habitats in Delaware Bay, including investigating the relationship between horseshoe crab egg availability and weight gain potential in Semipalmated Sandpipers, relationships between habitat use and foraging strategies, and migration phenology and connectivity using nanotag technology. In 2008, he initiated a comprehensive shorebird research and conservation program in northeastern South America with partners in Suriname, French Guiana and Brazil. This includes work on spatial relationships between wintering, migrating and breeding populations using remote sensing techniques and stable isotopes, habitat use and foraging behavior, physiological preparation for northward migration, the impacts of shrimp aquaculture on foraging behavior and contaminants exposure, and addressing illegal and unregulated shorebird hunting in the region. His current research endeavors to develop apparent winter survival estimates for Semipalmated Sandpipers in the northern region of South America and use these and similar data from migration staging and breeding areas to develop a full life-cycle, migration network model that helps to focus conservation strategies for the species.

Among more than one hundred awards he has received worldwide are the U. S. National Medal of Science, the Crafoord Prize (equivalent of the Nobel, for ecology) of the Royal Swedish Academy of Sciences, the International Prize of Biology of Japan; and in letters, two Pulitzer Prizes in nonfiction, the Nonino and Serono Prizes of Italy, and the COSMOS Prize of Japan. He is currently Honorary Curator in Entomology and University Research Professor Emeritus, Harvard University.
Dr. Katharine Parsons – Piping Plover Protection in Massachusetts: Recovering Populations and Facing Climate Change
January 7, 2019
Begun in 1987, Mass Audubon’s Coastal Waterbird Program (CWP) annually monitors Piping Plover (Charadrius melodus) nesting activity and protects habitat at 195 beach sites along 260 km of Massachusetts’ coastline. Nesting at these locations are approximately 220 pairs of plovers—a third of the Massachusetts population listed as “threatened” under state and federal endangered species laws. The CWP has investigated occurring and predicted climate change impacts to beach nesting Piping Plovers including rates of nest overwash. In addition, we have evaluated the impact of beach stabilization practices such as renourishment and beach re-vegetation on brood range and overall nesting success. Very little information is available to assist in guiding these practices with regard to optimizing habitat for plovers. As coastal conditions worsen from climate change effects, the stakes will increase for both protecting the built environment and providing beach habitat for endangered wildlife.
Katharine Parsons, Ph.D., Director, Coastal Waterbird Program, Mass Audubon, received her Bachelor’s degree from Smith College and Ph.D. in Ecology from Rutgers University. She has 35 years of experience in coastal waterbird research, management and policy in the northeast. Since 2011, Dr. Parsons has directed Mass Audubon’s Coastal Waterbird Program which works with coastal communities throughout Massachusetts to protect rare birds and their habitats. Her research has been published in over 45 peer-reviewed scientific publications. She is past-President of the Waterbird Society. In addition, Dr. Parsons is a Lecturer at Harvard’s Graduate School of Design where she has taught courses in landscape ecology, and currently teaches a seminar in coastal ecology entitled Changing Natural and Built Coastal Environments. over 45 peer-reviewed scientific publications. She is past-President of the Waterbird Society.

Dr. John Marzluff – Gifts of the Crow
June 3, 2019
Crows are mischievous, playful, social, and passionate. They have brains that are huge for their body size and exhibit an avian kind of eloquence. They mate for life and associate with relatives and neighbors for years. And because they often live near people—in our gardens, parks, and cities—they are also keenly aware of our peculiarities, staying away from and even scolding anyone who threatens or harms them and quickly learning to recognize and approach those who care for and feed them, even giving them numerous, oddly touching gifts in return. The ongoing connection between humans and crows—a cultural co-evolution—has shaped both species for millions of years. And the characteristics of crows that allow this symbiotic relationship are language, delinquency, frolic, passion, wrath, risk-taking, and awareness—seven traits that humans find strangely familiar.
With his extraordinary research on the intelligence and startling abilities of corvids—crows, ravens, and jays—scientist John Marzluff tells amazing stories of these brilliant birds in Gifts of the Crow, shining a light on their fascinating characteristics and behaviors. Teamed with artist and fellow naturalist Tony Angell, they offer an in-depth look at these complex creatures and our shared behaviors, illustrated with gorgeous line drawings. Crows gather around their dead, warn of impending doom, recognize people, commit murder of other crows, lure fish and birds to their death, drink beer, turn on lights to stay warm, design and use tools, use cars as nutcrackers, windsurf and sled to play, and work in tandem to get cheese whiz out of a can. Their marvelous brains allow them to think, plan, and reconsider their actions.
With its abundance of funny, awe-inspiring, and poignant stories, Gifts of the Crow portrays creatures who are nothing short of amazing. A testament to years of painstaking research, this fully illustrated, riveting work is a thrilling look at one of nature’s most wondrous creatures.
John Marzluff, Ph.D., is Professor of Wildlife Science at the University of Washington. His research has been the focus of articles in the New York Times, National Geographic, Audubon, Boys Life, The Seattle Times, and National Wildlife. PBS’s NATURE featured his raven research in its production, "Ravens," and his crow research in the film documentary, "A Murder of Crows."
John Marzluff is James W. Ridgeway Professor of Wildlife Science at the University of Washington. His graduate (Northern Arizona University) and initial post-doctoral (University of Vermont) research focused on the social behavior and ecology of jays and ravens. He was especially interested in communication, social organization, and foraging behavior (e.g., The Pinyon Jay, 1992, Academic Press). His current research brings this behavioral approach to pressing conservation issues including raptor management, management of pest species, and assessment of nest predation. His book, In the Company of Crows and Ravens (with Tony Angell, 2005 Yale U. Press) blends biology, conservation, and anthropology to suggest that human and crow cultures have co-evolved. This book won the 2006 Washington State Book Award for general nonfiction. With his wife, Colleen, he has just published Dog Days, Raven Nights (2011 Yale University Press), which combines reflection with biology and the recreational pursuit of dog sledding to show how a life in science blooms. Gifts of the Crow (2012 Free Press) applies a neurobiological perspective to understand the amazing feats of corvids. Welcome to Subirdia (2015 Yale University Press) details the urban ecology of birds, their challenges and triumphs, and how we can best conserve them. He has led studies on the effects of military training on falcons and eagles in southwestern Idaho, the effects of timber harvest, recreation, and forest fragmentation on goshawks and marbled murrelets in western Washington and Oregon, conservation strategies for Pacific Island crows, and the effects of urbanization on songbirds in the Seattle area. Dr. Marzluff has authored over 150 scientific papers on various aspects of bird behavior and wildlife management. He is a member of the board of editors for Acta Ornithologica, Landscape Ecology and Ecological Applications. He has edited Avian Conservation: Research and Management that includes 40 chapters detailing research approaches to conserve avian biodiversity throughout the world (1998, Island Press), Avian Conservation and Ecology in an Urbanizing World (2001, Kluwer Academic Publishers), Radiotelemetry and Animal Populations (2001, Academic Press), Urban Ecology: An International Perspective on the Interaction Between Humans and Nature (2008, Springer), and Perspectives in Urban Ecology (2011, Springer). He is currently a member of the U.S. Fish and Wildlife Service’s Recovery Team for the critically endangered Mariana Crow, a former member of the Washington Biodiversity Council, and a Fellow of the American Ornithologist's Union.
