David Benn begin birding in the 1970’s when a birder relative discovered a Yellow-green Vireo in his mother’s Brownsville yard (where later the first documented USA Golden-crowned Warbler was discovered) and he wondered what all the interest was. It turned out to be pretty compelling. As a Brownsville native his birding experience since has mostly been limited to South Texas and points south, including half a dozen trips to Central and South America and dozens of birding trips to Mexico. When he’s not thinking about going birding somewhere he’s probably thinking about going fishing.

Cindy Beckman is a retired public school teacher. Prior to founding Cheepers!, she organized and led trips for groups of students and parents, as well as for smaller groups of friends, family, and birders to destinations in the US and Central and South America. Cindy wrote about her experiences with young birders who she mentored during her 35 years as an educator, earning her WildBird Magazine’s 2007 “Birder of the Year” award. She is an avid photographer, eager to share images with fellow travelers. Cindy’s ABA life list tops 600, and her world list just went past the 3700 mark on a recent tour to southern Ecuador.
Jim Beckman is a retired Senior IT Project Manager who has been an avid birder for over 20 years. He has traveled extensively for most of his adult life, and loves to share birding experiences with others. He’s skilled at spotting birds and helping others find birds in the dense forest, although he frequently defers to expert local guides for positive identification. Always eager to help anyone who needs a bit of extra time or information to “get on” a bird, Jim is a valuable asset on any birding tour, regardless of the location. Jim’s ABA life list is just under 600, and his world list stands at 3644.

Carlos Bethancourt was born in Panama City in 1978 and raised in the small rural village of Huile, next to the Canal Zone. It was here where he learned many lessons of nature from his mother and grandmother, both of whom were deeply connected to nature and involved with conservation. After high school Carlos was awarded a scholarship to Mt. Hood Community College in Oregon, where he studied natural resources and received his first formal training in ornithology. Carlos began his career at the Canopy Tower in October of 2000 and has since attended numerous birding conferences and conventions in the US and Great Britain, where he led tours, workshops and presented programs on Panama birds. Carlos is a very popular and a much-requested guide, a testament not only to his birding ability, but also to his sincere friendly demeanor. When not guiding, Carlos is busy at the office working on marketing and other projects for the Canopy Tower & Canopy Lodge.

Erik Bruhnke has had a love for birds since he was a child. He graduated from Northland College in Wisconsin with a Natural Resources degree in 2008.

He has counted migrating raptors at the Corpus Christi HawkWatch in Texas. His avian field experiences have taken him throughout Oregon, Washington, Montana, Idaho, North and South Dakota, Maine, Texas, and western Canada. Erik’s wildlife photography has won national awards, and his writings have been featured in Birder’s Guide via the American Birding Association, BirdWatching, and Birdwatcher’s Digest. Erik leads tours for Victor Emanuel Nature Tours as well as his own business, Naturally Avian Birding Tours. Although he loves all birds, Erik is a devoted raptor and gull nerd. He currently splits his time between the tropics of South Texas and the Northwoods of Minnesota. He loves to cook and bake in his free time, often while sipping bird-friendly coffee.

John Brush
born in Iowa but raised in Texas, John’s early life is summed up perfectly by the saying “I wasn’t born in Texas, but got here as fast as I could.” Son of an ornithologist, John was out watching birds with his father at an early age. John got his B.S. from the University of Texas – Pan American (UTPA) in Fall 2013, and is back at UTPA to get his Master’s in Biology. One of his main interests is how we can make our urban areas better for bird diversity. His interest in conservation of birds in the Valley has seen him work at Quinta Mazatlan World Birding Center (2008-2014), conduct research with UTPA, and appear as a guest speaker for local nature centers and organizations. Nothing makes John happier than enjoying the incredible biodiversity of the Lower Rio Grande Valley and he is thrilled to be able to share that beauty and excitement with others.

Chip Clouse is a tour guide and sales/marketing rep for The Partnership for International Birding (PIB).

Tom Dunkerton
was a nature enthusiast as a kid growing up in NYC, he got his first birding field guide from his future wife when he was 18. Everything after that is all her fault!  Moving to Florida in 1995 allowed many of those wishful field guide images to come to life and he was hooked for good. Spending 4 years as a research technician studying the Florida Scrub-jay nurtured his intimate knowledge of Florida scrub habitat and it’s residents. Annually leading field trips for Florida Audubon chapters through Merritt Island National Wildlife Refuge as well as private birding adventures and photography workshops, Tom shares his passion with anyone who wants to tag along. Unending hours in the field inspired Tom to take up photography as well, to share what he saw with friends and family. That soon blossomed into photo presentations all over Florida and the southeast as well as a few contest accolades. It’s safe to say Tom is the walking definition of an OCD birder/nature photographer! He also is an Opticron Sport and Nature Optics prostaff, trying to help the world see Nature’s beauty a little clearer.

Kyle O’Haver grew up in Missouri spending much of my time in the woods and ponds of my grandparent’s farm. I grew up loving hunting, fishing, and catching all kinds of critters, but birds have always got my attention. Attending the University of Missouri-Columbia I found an amazing class called ornithology and loved it. Working with Missouri Department of Conservation in Fisheries and then an internship and seasonal interpretation job with Missouri State Parks, I finally landed a job with Estero Llano Grande State Park and World Birding Center. Three years as a park interpreter and three years as the Natural Resource Specialist created the obsessed birder you get today. Now running my own park and spreading the good word on birding, I hope my passion for birds pours into others like my children Sibley (not a coincidence) and Kaleb.
