John Chenoweth & Bill Reiner
John Chenoweth and Bill Reiner have been birding together since they worked as a team on the refuge from 2001 to 2004. In those years, they mapped territories of the refuge’s two endangered bird species, though their primary task was monitoring and control of the oak wilt fungus, earning them the nickname The Oak Wilt Boys. Today they are both employed as biologists with the City of Austin, where they continue to monitor and protect Golden-cheeked Warblers and Black-capped Vireos on lands of the Balcones Canyonlands Preserve. They enjoy challenging each other’s bird and plant identification skills, and sharing with refuge visitors their passion for exploring the natural communities of the Texas Hill Country.

Mary McCarley has always loved nature and photography. She traveled the US for many years as a professional dancer enjoying the outdoors along the way, but didn’t discover a more focused interest in birds until moving to the Texas Hill Country in 2007.

She is currently a member of Travis Audubon Society and helped establish and lead trips for Travis Audubon’s Young Birders Club, including the Bird-a-thon. She has volunteered with the Balcones Canyonlands NWR, including assisting during the Balcones Songbird Festival and participating in the last 6 Christmas Bird Counts.

Cheryl McGrath has lived in Austin since 1982, and has been actively birding Central Texas for the past ten years. Growing up in Central New York, her mother was an avid birder, who in 1975 spotted a Snowy Owl hanging out in nearby fields. It was a good bird to launch a life list, and a life-long fascination with birds great and small!
Dr. Jim Mueller
Dr. Jim Mueller is the Inventory and Monitoring Zone Biologist for six National Wildlife Refuges in central and east Texas. His office is at Balcones Canyonlands National Wildlife Refuge where one focus of his work is the management of woodlands, shrublands, and grasslands as habitat for native wildlife. He is currently leading a project to map the distribution of the Golden-cheeked Warbler population throughout its breeding range.
Dennis Palafox is a native Texan and first moved to Austin in 1975. He has B.S. and M.S in Biology. He has close to 40 years of experience in the natural resources field. Dennis developed his interest in birds as part of job duties. He says he “officially” became a birder about 14 years ago after taking Byron Stone’s Sparrow Class. He has expanded his knowledge about birds by taking classes, attending workshops, and by participating in Breeding Bird Surveys and Christmas Bird Counts. He has birded throughout Texas and the U.S. as well as Central America and Europe.
Dennis has been leading field trips for the Travis Audubon Society (TAS) for about three years. Recently, he became the TAS Field Trip Committee Chair. Dennis believes that birding should be a fun learning experience. He particularly enjoys leading field trips for new birders because he enjoys seeing their enthusiasm as they become more familiar with birds. His philosophy in leading field trips is that it’s a collaborative effort whereby the leader participates as a facilitator and works with participants to locate, identify, and become more familiar with birds. He also enjoys the social aspects of birding because he gets to make new friends with a shared common interest. More recently, like other birders, he has developed an interest in photographing and digiscoping birds. His goal is to take a picture of every species he sees.
Randy life has been defined by birds & birding since 1972. His focus is Texas and North American birds although he enjoys neotropical birding and has traveled widely in Mexico and Central America. Pinkston has a wildlife science degree from Aggieland and at one time hoped to make some sort of living in birds. Instead, he took the easy way out and became a surgeon so that he could afford to live a comfortable life while birding. He has led numerous birding tours in Texas & Arizona over the past 30+ years, including several central Texas winter sparrow workshops for Texas Ornithological Society. As a Life Member of TOS he has done Pineywoods breeding warbler trips and has served on its Bird Records Committee. He co-authored the Texas column for North American Birds magazine since 2004. Recently Randy has taken an interest in birding with a digital camera and telephoto lens.
