Past-President: Wendy Loeffler

Ms. Loeffler is a senior project manager and senior biologist with RECON Environmental, Inc. She obtained both a B.A. and M.A in Biology from California State University, Fullerton, where she studied the diets of locally nesting seabirds. Upon completion of her advanced degree, Ms. Loeffler entered the environmental consulting world. She worked first and briefly in Orange County, and then settled with RECON in San Diego over 17 years ago. She holds a recovery permit to study and survey for the coastal California gnatcatcher, fairy shrimp, and the Quino checkerspot butterfly. She has trained and conducted surveys for desert tortoise and flat-tailed horned lizard, as well as focused surveys for rare plants, sensitive riparian bird species, burrowing owls and other sensitive raptors, and assisted with mammal trapping, insect inventories, and pitfall trapping.

Ms. Loeffler has been involved with the local chapter for almost 5 years, starting out as the membership chair and subsequently being appointed as the Interim President when the previous leadership stepped down. She looks forward to growing the local chapter and seeing the program expand to provide greater benefit to southern California wildlife biologists. Ms. Loeffler resides in La Mesa, California with her son Garrett.

Colleen earned her bachelor’s degree in Biology and Spanish from the University of Wisconsin—Green Bay, and her master’s degree in Fish and Wildlife Management from Montana State University in Bozeman, where she examined survival and habitat use of greater sage grouse in southwestern Montana. She is interested in conservation biology, population dynamics, and habitat use of birds. Before coming to the Zoo, Colleen worked as a wildlife rehabilitator where she trained several raptors for educational purposes, and as a whooping crane tracker where she used radio and satellite telemetry to monitor a reintroduced population of whooping cranes. She has been a member of The Wildlife Society since college and has presented her work at a number of conferences over the years. Colleen loves that she gets to work outdoors and be creative to figure out how to answer research questions in the field. Her love for animals and nature grew from her time spent outdoors in the North Woods of Wisconsin.
