Learn a little more about the dynamic people that volunteer their valuable time to lead the varied field trips that Tucson Audubon has to offer. 

Kathe Anderson

Kathe Anderson

Kathe is an avid birder, leading bird walks, teaching classes, and counting birds for several bird surveys to help real scientists with data collection. For over 15 years, she’s led hundreds of walks for individuals, conservation organizations, private groups, and life-long learning programs, and taught dozens of hands-on birding-related classes for organizations such as the Verde Valley Nature and Birding Festival, Southwest Wings Nature Festival, Southeast Arizona Birding Festival, Mesa Community College, ASU’s Osher Life-long Learning Program, Arizona State Parks, The Nature Conservancy, the Desert Botanical Garden and others. She loves sharing her passion with others. She’s an active member of the Phoenix area and Tucson Audubon Societies. If it’s not fun, it’s not worth it.

Bowers 300x200

Bob and Prudy Bowers

Prudy and Bob have been nature nuts for decades, backpacking the Sierra and scuba diving the globe. In 2002, they retired from Oregon and moved to Tucson for the desert, the birding and easy access to Mexico, their favorite out-of-state destination for the past 45 years together. Their volunteer work includes Catalina State Park, Christmas Bird Counts, and two Tucson Bird Count parks. They love to share these interests with others, and especially enjoy introducing the joy of birding to beginners and those with mobility issues. When leading field trips, they focus on anecdotal information about birds, and they would rather have all participants see fewer birds than record a checklist seen only by a few. As participants know, home baked goodies are always provided. Their articles and photographs can be found at birdingthebrookeandbeyond.com.

Scott Crabtree 300x200

Scott Crabtree

Scott has been interested in birds from infancy, but it was a university course which got him started in birding in 1972. A career in the Navy had him cutting his birding teeth on pelagic species, and expanded his range around the country: the Carolinas, California, Connecticut, Texas, the Aleutian Islands, and the mid-Atlantic. He has: been on the board of directors for the San Antonio (TX) Audubon Society and the Baltimore Bird Club; conducted Breeding Bird Survey routes on the Aleutian Island of Adak; contributed to both additions of the Maryland Breeding Bird Atlas. Scott’s migratory days are over and is a full-time resident of Tucson.

Ray Deeney 300x200

Ray Deeney

A Brooklyn native, Ray Deeney began birding seriously about 1990 in New Jersey where he spent most of his adult life prior to moving to Tucson in 2011. At that time he retired as an attorney specializing in law and mental disability issues. Previously he had been a special education teacher, a social worker and a teacher at Seton Hall Law School for twelve years. In New Jersey he was also very active with New Jersey Audubon including field trips, Christmas bird counts and various citizen science projects.

Tim Helentjaris

Tim started paying attention to birds as a graduate student in the early 70’s in Utah, have since birded most extensively in the West but also on trips to Alaska, Hawaii, C. & S. America, Australia, New Zealand, Kenya. More of a biologist than a lister, I enjoy questions about bird behavior and occurrence, particularly the status of pioneering Mexican species in Arizona, as well as discovering new areas in Arizona that are under-birded. I also spend a lot of my time working on surveys of potential and existing IBA’s in AZ. Enthusiastic eBirder as I see the value of all of these data, given my previous career in science as a biologist.

John Higgins

John Higgins thinks wandering outside all morning looking at birds with some other sociable people is a great way to spend his time. He has been lucky enough to have birded from the Amazon to Alaska to Austria. He has been taking out field trips for Tucson Audubon for twenty years. John especially likes easy-going trips with beginner birders looking for easy-to-see birds, such as driving around looking at thousands of big Sandhill Cranes or sitting on a shady bench looking at close-up hummingbird feeders. John’s trips almost always end with eating apple pie or ice cream.

Holly is retired from the US Forest Service where she had a fulfilling career as a wildland firefighter and fire manager. Coming from a family of birders and nature enthusiasts, she is a lifelong backyard birder, and outdoor recreationist. Most every morning she is out walking and birding to increase her County Year and Life Lists, and her knowledge of local birds. She also birds wherever travels take her, which is often to the Caribbean for scuba diving with her husband, George, where they “list” fish as well. Besides leading birding field trips for various organizations, she participates in IBA and other bird surveys including Christmas Bird Counts. Holly is a great fan of eBird and other mobile birding applications. She is always willing to share how the use of these technologies has enhanced her birding experience.

Luke Safford 300x200

Luke Safford

Luke grew up in a family that loved the outdoors and quickly blossomed into a birder after his grandparents gave him his first bird book when he was seven. He was enamored with the idea of keeping track of the day-to-day bird life in his back yard near Tacoma, WA. Luke became involved in Yakima Valley Audubon and served on the board, as field trip coordinator, CBC compiler, and field trip leader. His favorite spot was along the Yakima River on the Poppoff Trail, where he led a weekly bird walk for three years. At the end of 2014 Luke and his family moved to Tucson and he quickly began attending, then leading, the Sweetwater Wetlands bird walk. This trip is one of Luke’s favorite moments of the week, catching up with the “regulars,” meeting new people from all over, helping new birders, and soaking in the bird life.

Laurel Salvador 300x200
