Richard Carlson

Richard started birding as a child in Minnesota 70 years ago. After a brief interlude at Harvard, where he majored in caving, mountain climbing, winter mountaineering and economics, he began birding again in Washington DC with the Maryland Ornithological Society. He was one of Chan Robbin’s volunteers in establishing the first Breeding Bird Surveys. Bribed by the Nixon administration to leave town with a fellowship to Stanford, he moved West in 1969. He worked at Stanford Research Institute, where he co-authored “Solar Energy in America’s Future” and led field trips for the Santa Clara Valley Audubon Society. He became President of the San Francisco Bay Bird Observatory and expanded his birding to Latin America. He has birded throughout the Neotropics and in Africa, Australia, Antarctica, India, China and Europe. He hopes to ultimately see at least half the birds of the world. He and his wife Pat now migrate between homes in Tucson and Lake Tahoe depending on where the birds are.


Les Corey

Les_CoreyLes grew up on a farm in New England and migrated from a rural coastal town along the Connecticut River to the desert and sky islands of Arizona in 1996. He has always been closely connected to the land and nature and has been hooked on birding for over 40 years after being smitten by his first Hooded Warbler during migration at a park in New Haven. Les has been a conservation executive for more than 38 years and birds and birding has always been an important element of his life.

Les has a long history with Audubon having first joined as a member in 1970 while organizing Earth Day programs at college. Beginning in 2001, Les held several leadership positions with National Audubon Society for 12 years where he oversaw field operations nationwide. His personal passion has always been focused on setting ambitious goals, harnessing the spirit of community collaboration, and translating it into meaningful conservation results – especially for birds and wildlife. Early in his career Les served as the Executive Director for both the Connecticut Audubon Society and the Audubon Society of New Hampshire where he initiated many programs including establishing several new Audubon Centers and sanctuaries. One of his favorites was working with Nellie Teale to establish the Edwin Way Teale Sanctuary at their farmstead in Eastern Connecticut. He has always been active with local Audubon Chapters and fondly remembers participating in Christmas Counts with Roger Tory Peterson as members of Potapaug Audubon in Old Lyme and tagging along on New Haven Bird Club field trips with 12 year old David Sibley.

A professional biologist, Les earned a BS degree in environmental biology for the University of Southern Connecticut and a Master’s degree in Forest Science from Yale University’s School of Forestry and Environmental Studies. Prior to his work with National Audubon, Les was a Vice President of The Nature Conservancy for 15 years and directed state programs in Connecticut and Arizona.

During his career he has raised millions in public and private funds for specific conservation projects protecting critical habitat for such diverse places as the San Pedro River, San Rafael Valley grasslands, Sonoran Desert, Tidelands of the Connecticut River, Long Island Sound, Darien Park in Panama, Rio Bravo Park in Belize, and Blue Mountains National Park in Jamaica. Les has led many Audubon and Conservancy expeditions outside the U.S. to generate support for conservation programs and expand his life list.

He currently serves on the Board of the Arizona Open Land and Water Trust, the Pima County Conservation Acquisition Commission, and works with the Arizona Wilderness Coalition. Les was instrumental in establishing the Arizona Common Ground Roundtable and chaired a committee advising Arizona’s Growing Smarter Commission. The recipient of numerous awards and special recognition for his achievements in conservation, his most cherished, the Charles Callison Award, was presented to Les in 2011 for his dedication to Audubon’s mission and for being a life-long champion of conservation.

Les and his family reside in Tucson, Arizona and is looking forward to semi-retirement and spending more time with our avian friends. In his free time Les enjoys birding, photography, hiking, gardening and exploring the wonders of nature with his spouse Bonnie and their four grandchildren.


Ed Curley

A graduate of the University of Arizona, Ed Curley was employed by the Pima County Regional Wastewater Reclamation Department (RWRD) for over 35 years. Prior to his retirement, Mr. Curley served as Strategic Planning Manager for the Department. In this position, he analyzed state and national water quality initiatives; coordinated regional water quality planning; managed the Wastewater Advisory Committee and worked with jurisdictions and tribal entities served by RWRD. His previous assignments included the development of 20-year $1.4 billion Capital Improvement Plan for the Department and Metropolitan Facility Plan Updates.

From 1995–2007, Ed served as Project Director of the Arid West Water Quality Research Project (AWWQRP), an EPA grant administered by RWRD to research the science and policy issues of water quality standards for arid environments. The Project produced a series of major technical and policy papers, published numerous scientific articles and made over 250 presentations throughout the West and the nation. Mr. Curley was co-editor of the resulting book: “Relevance of Ambient Water Quality Criteria for Ephemeral and Effluent-Department Watercourses of the Arid Western United States” published by the Society for Environmental Toxicology and Chemistry (SETAC 2008).

He is a past President and a longtime member of the Board of Directors of the Western Coalition of Arid States (WESTCAS). Ed has received a National Environmental Achievement Award from the Association of Metropolitan Sewage Agencies in 2002, a Metropolitan Pima Alliance “Common Ground” Award in 2005, and the WESTCAS President’s Award in 2007. Ed also received the WESTCAS Founders Award in both 1997 and 2015.

Ed became involved with birding in the early 1980’s and took part in the first birdathons held by Tucson Audubon. His favorite birding experiences include finding Elegant Trogons along Cave Creek, watching condors soar directly overhead on the updraft from a hot hillside in Southern California and taking a very foggy, choppy boat ride to see Atlantic puffins off the coast of Maine. Ed also served on the Tucson Audubon Board of Directors during this period and has been an active supporter of birding and the environment ever since.

Ed is currently involved with policy and research on water resources and the natural/built environment on an international scale. In 2011, Ed made a presentation on “The Role of NGOs in the Formation of US Water Policy” to the 3rd International WATArid Conference in Paris, France. Most recently, Ed has been a stakeholder in a multi-year European Union/United States joint venture titled the Sustainable Water Action (SWAN) Project. SWAN has brought together the scientific and stakeholder communities related to water resources management in Europe and the United States to establish a long-term sustainable water network though a “Transatlantic Water Dialogue”. Ed has participated in annual SWAN conferences in Europe and the United States and co-authored several articles on sustainable water resources with other SWAN stakeholders.


Kimberlyn Drew

Head_shot_Nov15Kimberlyn Drew has been in business and sales since she helped in her mom’s insurance agency as a kid. She went on to sell advertising to put herself through UCLA, then moved to Tucson to attend the UA’s Eller School for her MBA. After a successful corporate career at Honeywell, she returned to sales with a real estate license. When Kimberlyn joined Long Realty in 2006, she was one of the first members of Tucson Audubon’s nascent Birds & Business Alliance.

Kimberlyn Drew and her husband Andy Moore have been Audubon members since the mid-90’s, and have attended many Riparian Family Institutes, the Institute for Desert Ecology, and Bird & Wildlife Festivals with their daughter, Phoebe (a budding birder). Kimberlyn was the Honorary Chair for the 2015 Gala.

Kimberlyn is excited to join Tucson Audubon’s Board of Directors, to take her support for this important environmental organization to the next level, and to learn how she can put her business background to use in new and productive ways.


Laurens Halsey

Laurens has been passionate about (or maybe even obsessed with!) birds and birding for practically his entire life. His interest in birding was inspired by his parents, whom he delighted with his identification of an Indigo Bunting at the age of four (pronounced “Indian Bunny”). But birding has always meant more than just identifying the bird and moving on. Even as a young teenager, he sought a deeper connection with the birds. He wanted to get to know the birds, observe & study their plumages, behaviors, habits, and habitats. Once familiar with birds in his home state, he wanted to see more of the birds, and has birded throughout the United States from Washington to Florida, Maine to California, Texas, Alaska, and off three coasts. Laurens began visiting the premier birding destination of southeast Arizona in the early eighties and became a resident of the area in 1999.  Though he is most captivated by birds, Laurens is also enthusiastic about all creatures in the wild, whether they are covered with feathers, fur, scales, or some sort of exoskeleton. Today Laurens is a birding guide and wildlife photographer.  He formed Desert Harrier Guiding Services in 2007 and conducts day guiding & private tours for individuals & small groups throughout southeast Arizona and beyond. Guiding and sharing his photographs is Laurens’ way of helping others connect with nature. Laurens is a voting member of the Arizona Bird Committee, volunteers for Tucson Audubon and the Friends of Madera Canyon, and is an avid eBirder and regional eBird reviewer. He lives just outside of Madera Canyon near Green Valley with his very tolerant wife and the most precious cat in the world.

Doug Johnson

Doug was born in Maine and has lived in nine other states before moving to Arizona in 2017. He was seriously exposed to being in nature while a Boy Scout in California and Oklahoma, and took up birding in 1991. He was diagnosed in a serious case of the Listing Disease not too long after his first field trip with New Jersey Audubon. Doug has birded most regions of the U.S. and parts of Central America, South American, Europe, Asia and Africa. His son (an excellent birder) and wife (a reluctant, spousal birder) have accompanied him on some of these expeditions. Doug describes himself as a middling birder with poor eyesight and worse hearing. Recently he has started taking photographs of birds and hopes to advance, sometime, beyond the bird-on-a-stick level.

Doug received a Bachelor of Arts (Chemistry and History) from Grinnell College in 1973 and a Ph.D. (chemistry) from Northwestern University in 1977. He had career associated with chemistry in the chemical industry, academics and the petroleum industry. He and his wife recently retired and relocated to Arizona. Doug hopes to apply the appropriate experiences from a technical career to the Tucson Audubon Society Board of Directors.


R. Cynthia Pruett

Cynthia-Pruitt-with-raffle-tickets-by-Kendall-KroesenFor a long period I was what you might call a “lapsed birder”. I started birding in college with a boyfriend who became my husband and we traveled all over the United States while he was in the service; leading to a pretty comprehensive bird list. Then suddenly, other life activity got in the way and for about 25 years birding was shelved. In the late 80’s I was introduced to an avid woman birder at an environmental conference and the passion came back. My work career involved many executive jobs, some of them key environmental positions, which only reinforced my understanding of the need to protect important habitat around the world. It’s (the birding) led to many trips to many countries, a joy of seeing both new and revisited birds and of course, to becoming active in Audubon chapters, both here and in Virginia.


Deb Vath

Deb_VathDeb has been an elementary and middle-school teacher/librarian for most of her professional career. Noting that children rarely engage in outdoor activities, Deb has made it her mission to mentor students and provide opportunities for them to enjoy and appreciate southeast Arizona’s great outdoors. With the support of Tucson Audubon, she has developed the Trekking Rattlers, a local middle school student group that offers monthly nature outings to underprivileged youth. Deb offers birding opportunities to various youth groups in the Tucson Valley.
